Aging accentuates and bone marrow transplantation ameliorates metabolic defects in Fabry disease mice. (1/381)

Fabry disease is an X-linked metabolic disorder caused by a deficiency of alpha-galactosidase A (alpha-Gal A). The enzyme defect leads to the systemic accumulation of glycosphingolipids with alpha-galactosyl moieties consisting predominantly of globotriaosylceramide (Gb3). In patients with this disorder, glycolipid deposition in endothelial cells leads to renal failure and cardiac and cerebrovascular disease. Recently, we generated alpha-Gal A gene knockout mouse lines and described the phenotype of 10-week-old mice. In the present study, we characterize the progression of the disease with aging and explore the effects of bone marrow transplantation (BMT) on the phenotype. Histopathological analysis of alpha-Gal A -/0 mice revealed subclinical lesions in the Kupffer cells in the liver and macrophages in the skin with no gross lesions in the endothelial cells. Gb3 accumulation and pathological lesions in the affected organs increased with age. Treatment with BMT from the wild-type mice resulted in the clearance of accumulated Gb3 in the liver, spleen, and heart with concomitant elevation of alpha-Gal A activity. These findings suggest that BMT may have a potential role in the management of patients with Fabry disease.  (+info)

Fifteen-year follow-up of a heterozygous Fabry's disease patient associated with pre-excitation syndrome. (2/381)

A 47-year-old woman with heterozygous Fabry's disease with pre-excitation syndrome has been followed up for 15 years. Diagnosis was confirmed by the typical electron microscopic feature of the endomyocardial specimen and a decreased plasma alpha-galactosidase activity. As the disease progressed, the interventricular septum thickened from 11 to 17 mm as measured by echocardiography, while the AH interval was prolonged from 80 to 140 msec. In Fabry's disease, the PR interval has been reported to be variable from short PR to AV block. Therefore, this case may be helpful to understand the time course in the AV conduction abnormalities with the progression of Fabry's disease.  (+info)

Biopsy-proven cardiomyopathy in heterozygous Fabry's disease. (3/381)

A 23-year-old woman with heterozygous Fabry's disease who had acroparesthesia was admitted to hospital for precise examination of the disease before childbearing. She had no cardiac-related symptoms and no abnormality on physical examination. The alpha-galactosidase A activity in her leukocytes was present, but lower than normal. However, the endomyocardial biopsy showed specific changes for Fabry's disease. As Fabry's disease is a rare X-linked recessive inborn error of glycosphingolipid metabolism, heterozygous females are usually asymptomatic, but rarely can be affected as severely as hemizygous males. This is an isolated case of heterozygous Fabry's disease in a female in whom cardiac involvement was detected by endomyocardial biopsy, although she had no cardiac abnormality on physiological examinations. In conclusion, endomyocardial biopsy is useful for evaluation of the cardiac involvement of Fabry's disease even in an asymptomatic case.  (+info)

Infusion of alpha-galactosidase A reduces tissue globotriaosylceramide storage in patients with Fabry disease. (4/381)

Fabry disease is a lysosomal storage disorder caused by a deficiency of the lysosomal enzyme alpha-galactosidase A (alpha-gal A). This enzymatic defect results in the accumulation of the glycosphingolipid globotriaosylceramide (Gb(3); also referred to as ceramidetrihexoside) throughout the body. To investigate the effects of purified alpha-gal A, 10 patients with Fabry disease received a single i.v. infusion of one of five escalating dose levels of the enzyme. The objectives of this study were: (i) to evaluate the safety of administered alpha-gal A, (ii) to assess the pharmacokinetics of i.v.-administered alpha-gal A in plasma and liver, and (iii) to determine the effect of this replacement enzyme on hepatic, urine sediment and plasma concentrations of Gb(3). alpha-Gal A infusions were well tolerated in all patients. Immunohistochemical staining of liver tissue approximately 2 days after enzyme infusion identified alpha-gal A in several cell types, including sinusoidal endothelial cells, Kupffer cells, and hepatocytes, suggesting diffuse uptake via the mannose 6-phosphate receptor. The tissue half-life in the liver was greater than 24 hr. After the single dose of alpha-gal A, nine of the 10 patients had significantly reduced Gb(3) levels both in the liver and shed renal tubular epithelial cells in the urine sediment. These data demonstrate that single infusions of alpha-gal A prepared from transfected human fibroblasts are both safe and biochemically active in patients with Fabry disease. The degree of substrate reduction seen in the study is potentially clinically significant in view of the fact that Gb(3) burden in Fabry patients increases gradually over decades. Taken together, these results suggest that enzyme replacement is likely to be an effective therapy for patients with this metabolic disorder.  (+info)

Glycosphingolipid depletion in fabry disease lymphoblasts with potent inhibitors of glucosylceramide synthase. (5/381)

BACKGROUND: Fabry disease is an inherited X-linked disorder resulting in the loss of activity of the lysosomal hydrolase alpha-galactosidase A and causing the clinical manifestations of renal failure, cerebral vascular disease, and myocardial infarction. The phenotypic expression of this disorder is manifest by the accumulation of glycosphingolipids containing alpha-galactosyl linkages, most prominently globotriaosylceramide. METHODS: Based on quantitative structure activity studies, we recently reported two newly designed glucosylceramide synthase inhibitors based on 1-phenyl-2-palmitoylamino-3-pyrrolidino-1-propanol (P4). These inhibitors, 4'-hydroxy-P4 and ethylenedioxy-P4, were evaluated for their ability to deplete globotriaosylceramide and other glucosylceramide-based lipids in Fabry lymphocytes and were compared with N-butyldeoxynojirimycin, another reported glucosylceramide synthase inhibitor. RESULTS: Concentrations as low as 10 nmol/L of 4'-hydroxy-P4 and ethylenedioxy-P4 resulted in 70 and 80% depletion, respectively, of globotriaosylceramide, with maximal depletion occurring at three days of treatment. There was no impairment of cell growth. In contrast, N-butyldeoxynojirimycin only minimally lowered globotriaosylceramide levels, even at concentrations as high as 10 micromol/L. Globotriaosylceramide depletion was confirmed by the loss of binding of FITC-conjugated verotoxin B subunit to the lymphoblasts. CONCLUSIONS: These findings suggest that selective glucosylceramide synthase inhibitors are highly effective in the depletion of globotriaosylceramide from Fabry cell lines. We suggest that these compounds have potential therapeutic utility in the treatment of Fabry disease.  (+info)

Twenty novel mutations in the alpha-galactosidase A gene causing Fabry disease. (6/381)

BACKGROUND: Fabry disease, an X-linked inborn error of glycosphingolipid catabolism, results from the deficient activity of the lysosomal exoglycohydrolase alpha-galactosidase A (EC 3.2.1.22; alpha-Gal A). The nature of the molecular lesions in the alpha-Gal A gene in 30 unrelated families was determined to provide precise heterozygote detection, prenatal diagnosis, and define genotype-phenotype correlations. MATERIALS AND METHODS: Genomic DNA was isolated from affected males and/or carrier females from 30 unrelated families with Fabry disease. The entire alpha-Gal A coding region and flanking intronic sequences were analyzed by PCR amplification and automated sequencing. RESULTS: Twenty new mutations were identified, each in a single family: C142R, G183D, S235C, W236L, D244H, P259L, M267I, I289F, Q321E, C378Y, C52X, W277X, IVS4(+4), IVS6(+2), IVS6(-1), 35del13, 256del1, 892ins1, 1176del4, and 1188del1. In the remaining 10 unrelated Fabry families, 9 previously reported mutations were detected: M42V, R112C, S148R, D165V, N215S (in 2 families), Q99X, C142X, R227X, and 1072del3. Haplotype analysis using markers closely flanking the alpha-Gal A gene indicated that the two patients with the N215S lesion were unrelated. The IVS4(+4) mutation was a rare intronic splice site mutation that causes Fabry disease. CONCLUSIONS: These studies further define the heterogeneity of mutations in the alpha-Gal A gene causing Fabry disease, permit precise heterozygote detection and prenatal diagnosis, and help delineate phenotype-genotype correlations in this disease. +info)

Clinicopathologic analysis of 124 biopsy-proven peripheral nerve diseases. (7/381)

We reviewed dinical, histological and ultrastructural findings of 124 cases of sural nerve biopsy specimens to delineate the trends of peripheral nerve diseases in our institute. Eighty-one were men and 43 were women. We categorized them into five groups: specific diagnosis (66 cases, 53.2%), axonal degeneration type (47 cases, 37.9%), demyelinating type (4 cases, 3.2%), mixed axonal degeneration-demyelinating type (6 cases, 4.8%) and normal (1 case, 0.9%). Cases with specific diagnosis included 21 inflammatory demyelinating polyneuropathy (15 chronic inflammatory demyelinating polyradiculoneuropathy, 6 Guillain-Barre disease), 13 hereditary motor and sensory neuropathy (7 Charcot-Marie-Tooth type I, 6 Charcot-Marie-Tooth type II), 10 vasculitis, 6 toxic neuropathy, 4 leprosy, 3 diabetic neuropathy, 2 alcoholic neuropathy, 1 Fabry's disease and other specific diseases (5 cases). In our cases, the proportion of specific diagnoses was higher, while the proportion of demyelinating peripheral neuropathies and normal were lower than those of Western series. The results of this study indicate that 1) a dose clinicopathologic correlation is important to make a precise diagnosis of peripheral nerve biopsy, 2) Biopsy under strict indication may reduce unnecessary histologic examination, 3) There is no difference in disease pattern of peripheral neuropathy between Western people and Koreans.  (+info)

Characterization of two alpha-galactosidase mutants (Q279E and R301Q) found in an atypical variant of Fabry disease. (8/381)

The mutant products Q279E ((279)Gln to Glu) and R301Q ((301)Arg to Gln) of the X-chromosomal inherited alpha-galactosidase (EC 3.2.1. 22) gene, found in unrelated male patients with variant Fabry disease (late-onset cardiac form) were characterized. In contrast to patients with classic Fabry disease, who have no detectable alpha-galactosidase activity, atypical variants have residual enzyme activity. First, the properties of insect cell-derived recombinant enzymes were studied. The K(m) and V(max) values of Q279E, R301Q, and wild-type alpha-galactosidase toward an artificial substrate, 4-methylumbelliferyl-alpha-D-galactopyranoside, were almost the same. In order to mimic intralysosomal conditions, the degradation of the natural substrate, globotriaosylceramide, by the alpha-galactosidases was analyzed in a detergent-free-liposomal system, in the presence of sphingolipid activator protein B (SAP-B, saposin B). Kinetic analysis revealed that there was no difference in the degradative activity between the mutants and wild-type alpha-galactosidase activity toward the natural substrate. Then, immunotitration studies were carried out to determine the amounts of the mutant gene products naturally occurring in cells. Cultured lymphoblasts, L-57 (Q279E) and L-148 (R301Q), from patients with variant Fabry disease, and L-20 (wild-type) from a normal subject were used. The 50% precipitation doses were 7% (L-57) and 10% (L-148) of that for normal lymphoblast L-20, respectively. The residual alpha-galactosidase activity was 3 and 5% of the normal level in L-57 and L-148, respectively. The quantities of immuno cross-reacting materials roughly correlated with the residual alpha-galactosidase activities in lymphoblast cells from the patients. Compared to normal control cells, fibroblast cells from a patient with variant Fabry disease, Q279E mutation, secreted only small amounts of alpha-galactosidase activity even in the presence of 10 mM NH(4)Cl. It is concluded that Q279E and R301Q substitutions do not significantly affect the enzymatic activity, but the mutant protein levels are decreased presumably in the ER of the cells.  (+info)

Fabry disease is a rare X-linked inherited lysosomal storage disorder caused by mutations in the GLA gene, which encodes the enzyme alpha-galactosidase A. This enzyme deficiency leads to the accumulation of glycosphingolipids, particularly globotriaosylceramide (Gb3 or GL-3), in various tissues and organs throughout the body. The accumulation of these lipids results in progressive damage to multiple organ systems, including the heart, kidneys, nerves, and skin.

The symptoms of Fabry disease can vary widely among affected individuals, but common manifestations include:

1. Pain: Acroparesthesias (burning or tingling sensations) in the hands and feet, episodic pain crises, chronic pain, and neuropathy.
2. Skin: Angiokeratomas (small, red, rough bumps on the skin), hypohidrosis (decreased sweating), and anhydrosis (absent sweating).
3. Gastrointestinal: Abdominal pain, diarrhea, constipation, nausea, and vomiting.
4. Cardiovascular: Left ventricular hypertrophy (enlargement of the heart muscle), cardiomyopathy, ischemic heart disease, arrhythmias, and valvular abnormalities.
5. Renal: Proteinuria (protein in the urine), hematuria (blood in the urine), chronic kidney disease, and end-stage renal disease.
6. Nervous system: Hearing loss, tinnitus, vertigo, stroke, and cognitive decline.
7. Ocular: Corneal opacities, cataracts, and retinal vessel abnormalities.
8. Pulmonary: Chronic cough, bronchial hyperresponsiveness, and restrictive lung disease.
9. Reproductive system: Erectile dysfunction in males and menstrual irregularities in females.

Fabry disease affects both males and females, but the severity of symptoms is generally more pronounced in males due to the X-linked inheritance pattern. Early diagnosis and treatment with enzyme replacement therapy (ERT) or chaperone therapy can help manage the progression of the disease and improve quality of life.

Alpha-galactosidase is an enzyme that breaks down complex carbohydrates, specifically those containing alpha-galactose molecules. This enzyme is found in humans, animals, and microorganisms. In humans, a deficiency of this enzyme can lead to a genetic disorder known as Fabry disease, which is characterized by the accumulation of these complex carbohydrates in various tissues and organs, leading to progressive damage. Alpha-galactosidase is also used as a medication for the treatment of Fabry disease, where it is administered intravenously to help break down the accumulated carbohydrates and alleviate symptoms.

Trihexosylceramides are a type of glycosphingolipids, which are complex lipids found in animal tissues. They consist of a ceramide molecule (a sphingosine and fatty acid) with three hexose sugars attached to it in a specific sequence, typically glucose-galactose-galactose.

Trihexosylceramides are further classified into two types based on the type of ceramide they contain: lactosylceramide (Gal-Glc-Cer) and isoglobotrihexosylceramide (GalNAcβ1-4Galβ1-4Glc-Cer).

These lipids are important components of the cell membrane and play a role in various biological processes, including cell recognition, signal transduction, and cell adhesion. Abnormal accumulation of trihexosylceramides has been implicated in certain diseases, such as Gaucher disease and Tay-Sachs disease, which are caused by deficiencies in enzymes involved in their breakdown.

Enzyme Replacement Therapy (ERT) is a medical treatment approach in which functional copies of a missing or deficient enzyme are introduced into the body to compensate for the lack of enzymatic activity caused by a genetic disorder. This therapy is primarily used to manage lysosomal storage diseases, such as Gaucher disease, Fabry disease, Pompe disease, and Mucopolysaccharidoses (MPS), among others.

In ERT, the required enzyme is produced recombinantly in a laboratory using biotechnological methods. The purified enzyme is then administered to the patient intravenously at regular intervals. Once inside the body, the exogenous enzyme is taken up by cells, particularly those affected by the disorder, and helps restore normal cellular functions by participating in essential metabolic pathways.

ERT aims to alleviate disease symptoms, slow down disease progression, improve quality of life, and increase survival rates for patients with lysosomal storage disorders. However, it does not cure the underlying genetic defect responsible for the enzyme deficiency.

1-Deoxynojirimycin (DNJ) is an antagonist of the enzyme alpha-glucosidase, which is involved in the digestion of carbohydrates. DNJ is a naturally occurring compound found in some plants, including mulberry leaves and the roots of the African plant Moringa oleifera. It works by binding to the active site of alpha-glucosidase and inhibiting its activity, which can help to slow down the digestion and absorption of carbohydrates in the small intestine. This can help to reduce postprandial glucose levels (the spike in blood sugar that occurs after a meal) and may have potential benefits for the management of diabetes and other metabolic disorders. DNJ is also being studied for its potential anti-cancer effects.

Alpha-N-Acetylgalactosaminidase (also known as alpha-GalNAcase) is an enzyme that belongs to the class of glycoside hydrolases. Its systematic name is N-acetyl-alpha-galactosaminide galactosaminohydrolase. This enzyme is responsible for catalyzing the hydrolysis of the terminal, non-reducing N-acetyl-D-galactosamine residues in gangliosides and glycoproteins.

Gangliosides are sialic acid-containing glycosphingolipids found in animal tissues, especially in the nervous system. Glycoproteins are proteins that contain oligosaccharide chains (glycans) covalently attached to their polypeptide backbone.

Deficiency or dysfunction of alpha-N-Acetylgalactosaminidase can lead to various genetic disorders, such as Schindler and Kanzaki diseases, which are characterized by the accumulation of gangliosides and glycoproteins in lysosomes, leading to progressive neurological deterioration.

Aphorisms are concise, pithy statements that express a general truth or principle in a clever or memorable way. They often relate to a specific area of knowledge or experience, such as medicine or morality. In the context of medicine, medical aphorisms are sayings or phrases that convey important principles or wisdom related to the practice of medicine. Examples include "First do no harm" (Hippocrates) and "When in doubt, cut it out" (William Stewart Halsted).

Proverbs, on the other hand, are traditional sayings that express a general truth or piece of advice based on common sense or folk wisdom. They often take the form of simple sentences or phrases and may be metaphorical or figurative in nature. Medical proverbs might include sayings like "The patient's own doctor is the best" or "An ounce of prevention is worth a pound of cure."

Together, aphorisms and proverbs can serve as useful tools for medical professionals to remember important principles and practices, as well as communicate complex ideas in a simple and memorable way.

A hemizygote is an individual or a cell that has only one copy of a particular gene, as opposed to the usual two copies (one from each parent) in a diploid organism. This condition typically occurs when the gene is located on a sex chromosome (X or Y). For example, males in humans are hemizygous for all genes located on the X chromosome since they have only one X chromosome and one Y chromosome. If a recessive allele is present on the X chromosome of a male, he will express that trait because there is no corresponding allele to mask its effect. In contrast, females have two X chromosomes and would need to inherit two copies of the recessive allele to express the trait.

The pulvinar is a part of the brain that is located in the thalamus, which is a structure situated deep within the brain. The pulvinar plays a crucial role in visual processing and attention. It is the largest nucleus in the thalamus and is composed of several subdivisions, each with distinct connections to different areas of the cerebral cortex.

The pulvinar receives inputs from various sources, including the retina, superior colliculus, and visual cortex. It then sends outputs to multiple regions of the visual cortex, as well as other parts of the brain involved in attention and awareness. The pulvinar has been shown to modulate the flow of information between different areas of the visual system, allowing for the integration of visual information with other sensory inputs and attentional processes.

Damage to the pulvinar can result in a variety of visual deficits, including impairments in visual attention, object recognition, and motion perception. Additionally, some studies have suggested that the pulvinar may be involved in the regulation of consciousness and arousal.

Glycosphingolipids are a type of complex lipid molecule found in animal cell membranes, particularly in the outer leaflet of the plasma membrane. They consist of a hydrophobic ceramide backbone, which is composed of sphingosine and fatty acids, linked to one or more hydrophilic sugar residues, such as glucose or galactose.

Glycosphingolipids can be further classified into two main groups: neutral glycosphingolipids (which include cerebrosides and gangliosides) and acidic glycosphingolipids (which are primarily gangliosides). Glycosphingolipids play important roles in various cellular processes, including cell recognition, signal transduction, and cell adhesion.

Abnormalities in the metabolism or structure of glycosphingolipids have been implicated in several diseases, such as lysosomal storage disorders (e.g., Gaucher's disease, Fabry's disease) and certain types of cancer (e.g., ganglioside-expressing neuroblastoma).

Metabolic brain diseases are a group of disorders caused by genetic defects that affect the body's metabolism and result in abnormal accumulation of harmful substances in the brain. These conditions are present at birth (inborn) or develop during infancy or early childhood. Examples of metabolic brain diseases that are present at birth include:

1. Phenylketonuria (PKU): A disorder caused by a deficiency of the enzyme phenylalanine hydroxylase, which leads to an accumulation of phenylalanine in the brain and can cause intellectual disability, seizures, and behavioral problems if left untreated.
2. Maple syrup urine disease (MSUD): A disorder caused by a deficiency of the enzyme branched-chain ketoacid dehydrogenase, which leads to an accumulation of branched-chain amino acids in the body and can cause intellectual disability, seizures, and metabolic crisis if left untreated.
3. Urea cycle disorders: A group of disorders caused by defects in enzymes that help remove ammonia from the body. Accumulation of ammonia in the blood can lead to brain damage, coma, or death if not treated promptly.
4. Organic acidemias: A group of disorders caused by defects in enzymes that help break down certain amino acids and other organic compounds. These conditions can cause metabolic acidosis, seizures, and developmental delays if left untreated.

Early diagnosis and treatment of these conditions are crucial to prevent irreversible brain damage and other complications. Treatment typically involves dietary restrictions, supplements, and medications to manage the underlying metabolic imbalance. In some cases, enzyme replacement therapy or liver transplantation may be necessary.

Sphingolipids are a class of lipids that contain a sphingosine base, which is a long-chain amino alcohol with an unsaturated bond and an amino group. They are important components of animal cell membranes, particularly in the nervous system. Sphingolipids include ceramides, sphingomyelins, and glycosphingolipids.

Ceramides consist of a sphingosine base linked to a fatty acid through an amide bond. They play important roles in cell signaling, membrane structure, and apoptosis (programmed cell death).

Sphingomyelins are formed when ceramides combine with phosphorylcholine, resulting in the formation of a polar head group. Sphingomyelins are major components of the myelin sheath that surrounds nerve cells and are involved in signal transduction and membrane structure.

Glycosphingolipids contain one or more sugar residues attached to the ceramide backbone, forming complex structures that play important roles in cell recognition, adhesion, and signaling. Abnormalities in sphingolipid metabolism have been linked to various diseases, including neurological disorders, cancer, and cardiovascular disease.

Angiokeratoma is a cutaneous condition characterized by the presence of small, dilated blood vessels (capillaries) in the upper dermis, which are covered by thickened epidermis. These lesions appear as dark red to black papules or plaques on the skin surface. They can occur spontaneously or as a result of an underlying medical condition such as Fabry disease. Angiokeratomas are typically asymptomatic but may occasionally cause mild discomfort or itching. They most commonly affect the lower extremities, particularly the buttocks and genital region, but can also appear on other parts of the body.

Glycolipids are a type of lipid (fat) molecule that contain one or more sugar molecules attached to them. They are important components of cell membranes, where they play a role in cell recognition and signaling. Glycolipids are also found on the surface of some viruses and bacteria, where they can be recognized by the immune system as foreign invaders.

There are several different types of glycolipids, including cerebrosides, gangliosides, and globosides. These molecules differ in the number and type of sugar molecules they contain, as well as the structure of their lipid tails. Glycolipids are synthesized in the endoplasmic reticulum and Golgi apparatus of cells, and they are transported to the cell membrane through vesicles.

Abnormalities in glycolipid metabolism or structure have been implicated in a number of diseases, including certain types of cancer, neurological disorders, and autoimmune diseases. For example, mutations in genes involved in the synthesis of glycolipids can lead to conditions such as Tay-Sachs disease and Gaucher's disease, which are characterized by the accumulation of abnormal glycolipids in cells.

Neutral glycosphingolipids (NGSLs) are a type of glycosphingolipid, which are lipids that contain a ceramide backbone with one or more sugar residues attached. NGSLs are characterized by the absence of charged groups in their carbohydrate moiety. They consist of a core structure of ceramide, to which one or more sugars such as glucose or galactose are attached.

NGSLs can be further classified into two main categories: cerebrosides and globosides. Cerebrosides contain a single sugar residue (monosaccharide) attached to the ceramide backbone, while globosides contain more complex oligosaccharide chains. NGSLs are important components of cell membranes and play a role in various biological processes, including cell recognition, signal transduction, and cell adhesion.

Abnormal accumulation of NGSLs can lead to various genetic disorders known as sphingolipidoses, such as Gaucher's disease, Fabry's disease, and Krabbe's disease. These conditions are characterized by the buildup of lipids in various organs and tissues, leading to progressive damage and dysfunction.

Isoenzymes, also known as isoforms, are multiple forms of an enzyme that catalyze the same chemical reaction but differ in their amino acid sequence, structure, and/or kinetic properties. They are encoded by different genes or alternative splicing of the same gene. Isoenzymes can be found in various tissues and organs, and they play a crucial role in biological processes such as metabolism, detoxification, and cell signaling. Measurement of isoenzyme levels in body fluids (such as blood) can provide valuable diagnostic information for certain medical conditions, including tissue damage, inflammation, and various diseases.

Pasteurellosis, pneumonic is a specific form of pasteurellosis that is caused by the bacterium *Pasteurella multocida* and primarily affects the respiratory system. It is characterized by inflammation and infection of the lungs (pneumonia) and can result in symptoms such as cough, difficulty breathing, chest pain, fever, and decreased appetite.

This condition often occurs as a secondary infection in animals with underlying respiratory diseases, and it can be transmitted to humans through close contact with infected animals, such as through bites, scratches, or inhalation of respiratory secretions. Pneumonic pasteurellosis is more likely to occur in people who have weakened immune systems due to other health conditions.

Prompt medical treatment with antibiotics is necessary to prevent complications and improve outcomes. The prognosis for pneumonic pasteurellosis depends on the severity of the infection, the patient's overall health, and how quickly they receive appropriate medical care.

I'm sorry for any confusion, but "New Zealand" is not a medical term or concept. It is a country located in the southwestern Pacific Ocean, known for its stunning landscapes, unique wildlife, and as the filming location for the "Lord of the Rings" films. If you have any questions related to medicine or health, I'd be happy to try and help answer those for you!
