Presence of Yersinia enterocolitica in tissues of orally-inoculated pigs and the tonsils and feces of pigs at slaughter. (1/490)
In order to study the early events associated with infection of swine by Yersinia enterocolitica, 42 five-week-old crossbred piglets were inoculated per os with approximately 10(8) Y. enterocolitica O:3. Groups of 5 animals (and one negative control) were euthanized 30 min, 3, 6, 12, 24, 48 and 72 h following the infection. Palatine tonsils, retropharyngeal and mesenteric lymph nodes, esophagus, duodenum, jejunum, ileum (and Peyer's patches), stomach, liver, spleen and feces (from colon) were collected and analyzed for the presence of Y. enterocolitica by standard bacteriological procedures. Natural infections were also analyzed, as a complementary study, by taking one-gram samples of fecal material and tonsils from 291 pig carcasses less than 3 h after slaughter and culturing them for Y. enterocolitica using a cold enrichment technique. Within 30 min, Yersinia enterocolitica O:3 was already present at most sites. The presence of Y. enterocolitica in the liver of 3 out of 10 animals and also in the spleen of 3 out of 10 piglets, within the first 3 h postinfection, but not at later times (with one exception), probably indicated a transient bacteremia accompanying the initial stages of infection. The tonsils were colonized in most animals (13/20) as the bacteria remained present from 12 to 72 h postinfection, while only 4 out of 20 fecal samples were found to be positive over the same period. Up to 10(4) colony-forming units of Y. enterocolitica per gram of tonsil and fecal material were recovered. Finally, among the 291 animals sampled at the abattoir, a total of 79 were found positive, 70 of the tonsils sampled were positive, and bacteria were recovered in 17 fecal samples. It is therefore suggested that palatine tonsils are the most reliable tissue for the indication of an infection/colonization by Y. enterocolitica O:3 in swine and that the removal of this tissue during the slaughter process should be considered in order to minimize the possibility of contamination of meat products. (+info)Seroepidemiologic study on the occurrence of antibodies against Yersinia enterocolitica and Yersinia pseudotuberculosis in urban and rural population of the Lublin region (eastern Poland). (2/490)
The aim of this study was to assess the seroprevalence of antibodies against Yersinia in the rural and urban population and to determine the frequency of particular serotypes of Yersinia enterocolitica and Yersinia pseudotuberculosis. 472 sera were examined, 257 of rural inhabitants and 215 of urban inhabitants. The survey was carried out by passive hemagglutination test with the antigens of Yersinia serotypes considered pathogenic for humans: Y. enterocolitica 03, 05, 06, 08, 09 and Y. pseudotuberculosis I and III. In the examined rural population positive reactions to Yersinia antigens were significantly more frequent than in the examined urban population (42% versus 20%, p<0.0001). The most frequent reactions were against Y. enterocolitica serotypes 05 and 08. (+info)No benefit of long-term ciprofloxacin treatment in patients with reactive arthritis and undifferentiated oligoarthritis: a three-month, multicenter, double-blind, randomized, placebo-controlled study. (3/490)
OBJECTIVE: To investigate the effect of long-term antibiotic treatment in patients with reactive arthritis (ReA) and undifferentiated oligoarthritis. METHODS: One hundred twenty-six patients were treated with ciprofloxacin (500 mg twice a day) or placebo for 3 months, in a double-blind, randomized study. Of these patients, 104 (48 treated with ciprofloxacin and 56 treated with placebo) were valid for clinical evaluation: 55 were diagnosed as having ReA with a preceding symptomatic urogenic or enteric infection and 49 as having undifferentiated oligoarthritis. These 2 groups were randomized separately. The triggering bacterium was sought by serology and/or culture. The percentage of patients in remission after 3 months of treatment was chosen as the primary efficacy parameter. RESULTS: A triggering bacterium could be identified in 52 patients (50%): Chlamydia trachomatis in 13, Yersinia in 14, and Salmonella in 25. No patient was positive for Campylobacter jejuni or for Shigella. No difference in outcome was found between treatment with ciprofloxacin or placebo in the whole group or in subgroups of patients with ReA or undifferentiated oligoarthritis. No difference was seen in patients with a disease duration <3 months. Ciprofloxacin was not effective in Yersinia- or Salmonella-induced arthritis but seemed to be better than placebo in Chlamydia-induced arthritis. This difference was not significant, however, which might be due to the small sample size. CONCLUSION: Long-term treatment of ReA with ciprofloxacin is not effective; however, it might be useful in the subgroup of patients who have Chlamydia-induced arthritis. This has to be proven in a bigger study focusing on patients with Chlamydia-induced arthritis. (+info)Tumor necrosis factor receptor p55 controls the severity of arthritis in experimental Yersinia enterocolitica infection. (4/490)
OBJECTIVE: To dissect the host defense mechanisms in relation to the development of Yersinia-associated arthritis by evaluating the impact of tumor necrosis factor receptor p55 (TNFRp55) deficiency on Yersinia enterocolitica infection. METHODS: TNFRp55-/- and C57BL/6 mice were inoculated intravenously with arthritogenic strain 8081 of Yenterocolitica serotype 0:8. Mice were observed daily for generating survival curves and monitoring arthritis. In subsequent sets of experiments, mice were sacrificed at day 14 after infection for examination of histopathology of joints, bacterial clearance, macrophage microbicidal activity, nitric oxide (NO) production, oxidative burst generation, and cytokine production. RESULTS: There was an 80% mortality rate in TNFRp55-/- mice compared with 25% in the controls at 8 weeks after inoculation with 70 colony-forming units of Y. enterocolitica 0:8. Histologic examination of joint tissues revealed that TNFRp55-/- mice developed more severe arthritis, including cartilage degradation and bony destruction, than controls at day 14 after infection. The more extensive joint pathology in TNFRp55-/- mice was correlated with the higher bacterial load in liver, spleen, and lungs, and with the increased levels of interleukin-10. TNFRp55-/- mice displayed impaired intracellular killing of bacteria by macrophages. This was associated with decreased NO production and impaired oxidative burst activity. CONCLUSION: This study demonstrates that TNF signaling through TNFRp55 controls the severity of Yersinia-induced arthritis and implicates TNF-mediated macrophage microbicidal activity as a central event in this process. (+info)Enterobacterial infection modulates major histocompatibility complex class I expression on mononuclear cells. (5/490)
Major histocompatibility complex (MHC) class I expression is reduced in several viral infections, but it is not known whether the same happens during infections caused by intracellular enterobacteria. In this study, the expression of MHC class I antigens on peripheral blood mononuclear cells (PBMC) from 16 patients with Salmonella, Yersinia, or Klebsiella infection was investigated. During or after the acute infection, the expression of MHC class I antigens was markedly decreased in eight patients, all with genotype HLA-B27, and six out of eight with reactive arthritis (ReA). A significant decrease of monomorphic MHC class I was found in three patients, of HLA-B27 in eight (P<0.05) and of HLA-A2 in two. However, patients negative for the HLA-B27 genotype, or healthy HLA-B27-positive individuals, did not have a significant decrease of MHC class I antigens. During the decreased expression on the cell surface, intracellular retention of MHC class I antigens was observed, whereas HLA-B27 mRNA levels did not vary significantly. This is the first evidence that enterobacterial infection may down-regulate expression of MHC class I molecules in vivo and that down-regulation is predominant in patients with the HLA-B27 genotype. (+info)Characterization of the interaction between Yersinia enterocolitica biotype 1A and phagocytes and epithelial cells in vitro. (6/490)
Yersinia enterocolitica strains of biotype 1A are increasingly being recognized as etiological agents of gastroenteritis. However, the mechanisms by which these bacteria cause disease differ from those of highly invasive, virulence plasmid-bearing Y. enterocolitica strains and are poorly understood. We have investigated several biotype 1A strains of diverse origin for their ability to resist killing by professional phagocytes. All strains were rapidly killed by polymorphonuclear leukocytes but persisted within macrophages (activated with gamma interferon) to a significantly greater extent (survival = 40.5% +/- 17.4%) than did Escherichia coli HB101 (9.3% +/- 0.7%; P = 0.0001). Strains isolated from symptomatic patients were significantly more resistant to killing by macrophages (survival = 48.9% +/- 19.5%) than were strains obtained from food or the environment (survival = 32.1% +/- 10.3%; P = 0.04). Some strains which had been ingested by macrophages or HEp-2 epithelial cells showed a tendency to reemerge into the tissue culture medium over a period lasting several hours. This phenomenon, which we termed "escape," was observed in 14 of 15 strains of clinical origin but in only 3 of 12 nonclinical isolates (P = 0.001). The capacity of bacteria to escape from cells was not directly related to their invasive ability. To determine if escape was due to host cell lysis, we used a variety of techniques, including lactate dehydrogenase release, trypan blue exclusion, and examination of infected cells by light and electron microscopy, to measure cell viability and lysis. These studies established that biotype 1A Y. enterocolitica strains were able to escape from macrophages or epithelial cells without causing detectable cytolysis, suggesting that escape was achieved by a process resembling exocytosis. The observations that biotype 1A Y. enterocolitica strains of clinical origin are significantly more resistant to killing by macrophages and significantly more likely to escape from host cells than are strains of nonclinical origin suggest that these properties may account for the virulence of these bacteria. (+info)Generalized transduction of small Yersinia enterocolitica plasmids. (7/490)
To study phage-mediated gene transfer in Yersinia, the ability of Yersinia phages to transduce naturally occurring plasmids was investigated. The transduction experiments were performed with a temperate phage isolated from a pathogenic Yersinia enterocolitica strain and phage mixtures isolated from sewage. Small plasmids (4.3 and 5.8 kb) were transduced at a frequency of 10(-5) to 10(-7)/PFU. However, we could not detect the transduction of any indigenous virulence plasmid (ca. 72 kb) in pathogenic Yersinia strains. Transductants obtained by infection with the temperate phage were lysogenic and harbored the phage genome in their chromosomes. (+info)Purification and characterization of an extracellular protease from the fish pathogen Yersinia ruckeri and effect of culture conditions on production. (8/490)
A novel protease, hydrolyzing azocasein, was identified, purified, and characterized from the culture supernatant of the fish pathogen Yersinia ruckeri. Exoprotease production was detected at the end of the exponential growth phase and was temperature dependent. Activity was detected in peptone but not in Casamino Acid medium. Its synthesis appeared to be under catabolite repression and ammonium control. The protease was purified in a simple two-step procedure involving ammonium sulfate precipitation and ion-exchange chromatography. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis of the purified protein indicated an estimated molecular mass of 47 kDa. The protease had characteristics of a cold-adapted protein, i.e., it was more active in the range of 25 to 42 degrees C and had an optimum activity at 37 degrees C. The activation energy for the hydrolysis of azocasein was determined to be 15.53 kcal/mol, and the enzyme showed a rapid decrease in activity at 42 degrees C. The enzyme had an optimum pH of around 8. Characterization of the protease showed that it required certain cations such as Mg(2+) or Ca(2+) for maximal activity and was inhibited by EDTA, 1,10-phenanthroline, and EGTA but not by phenylmethylsulfonyl fluoride. Two N-methyl-N-nitro-N-nitrosoguanidine mutants were isolated and analyzed; one did not show caseinolytic activity and lacked the 47-kDa protein, while the other was hyperproteolytic and produced increased amounts of the 47-kDa protein. Azocasein activity, SDS-PAGE, immunoblotting by using polyclonal anti-47-kDa-protease serum, and zymogram analyses showed that protease activity was present in 8 of 14 strains tested and that two Y. ruckeri groups could be established based on the presence or absence of the 47-kDa protease. (+info)Yersinia infections are diseases caused by gram-negative bacteria of the genus Yersinia, including Y. pestis (plague), Y. enterocolitica, and Y. pseudotuberculosis, which can lead to a range of symptoms from gastroenteritis to severe systemic illness.
Yersinia infections are caused by bacteria of the genus Yersinia, with Y. pestis (causing plague), Y. enterocolitica, and Y. pseudotuberculosis being the most common species associated with human illness. These bacteria can cause a range of symptoms depending on the site of infection.
Y. enterocolitica and Y. pseudotuberculosis primarily infect the gastrointestinal tract, causing yersiniosis. Symptoms may include diarrhea (often containing blood), abdominal pain, fever, vomiting, and inflammation of the lymph nodes in the abdomen. In severe cases, these bacteria can spread to other parts of the body, leading to more serious complications such as sepsis or meningitis.
Y. pestis is infamous for causing plague, which can manifest as bubonic, septicemic, or pneumonic forms. Bubonic plague results from the bite of an infected flea and causes swollen, painful lymph nodes (buboes) in the groin, armpits, or neck. Septicemic plague occurs when Y. pestis spreads through the bloodstream, causing fever, chills, extreme weakness, and potential organ failure. Pneumonic plague is a severe respiratory infection caused by inhaling infectious droplets from an infected person or animal; it can lead to rapidly progressing pneumonia, sepsis, and respiratory failure if left untreated.
Proper diagnosis of Yersinia infections typically involves laboratory testing of bodily fluids (e.g., blood, stool) or tissue samples to identify the bacteria through culture, PCR, or serological methods. Treatment usually consists of antibiotics such as doxycycline, fluoroquinolones, or aminoglycosides, depending on the severity and type of infection. Preventive measures include good hygiene practices, prompt treatment of infected individuals, and vector control to reduce the risk of transmission.
Yersinia enterocolitica is a gram-negative, facultatively anaerobic, rod-shaped bacterium that primarily causes gastrointestinal infections, often resulting in enterocolitis, and can be transmitted through contaminated food and water, leading to symptoms such as diarrhea, abdominal pain, and fever.
"Yersinia enterocolitica" is a gram-negative, facultatively anaerobic, rod-shaped bacterium that is capable of causing gastrointestinal infections in humans. It is commonly found in the environment, particularly in water and soil, as well as in animals such as pigs, cattle, and birds.
Infection with Yersinia enterocolitica can cause a range of symptoms, including diarrhea, abdominal pain, fever, and vomiting. The infection is typically transmitted through the consumption of contaminated food or water, although it can also be spread through person-to-person contact.
Yersinia enterocolitica infections are more common in young children and older adults, and they tend to occur more frequently during colder months of the year. The bacterium is able to survive at low temperatures, which may contribute to its prevalence in cooler climates.
Diagnosis of Yersinia enterocolitica infection typically involves the detection of the bacterium in stool samples or other clinical specimens. Treatment usually involves antibiotics and supportive care to manage symptoms. Prevention measures include good hygiene practices, such as washing hands thoroughly after using the bathroom and before handling food, as well as cooking meats thoroughly and avoiding consumption of raw or undercooked foods.
Yersinia pseudotuberculosis infections are foodborne illnesses caused by the consumption of contaminated water or raw fruits and vegetables, resulting in gastrointestinal symptoms such as diarrhea, vomiting, and abdominal pain, which can progress to severe complications including sepsis and mesenteric lymphadenitis.
"Yersinia pseudotuberculosis" infections refer to illnesses caused by the bacterium Yersinia pseudotuberculosis. This gram-negative, rod-shaped bacterium is found in the environment, particularly in soil and water contaminated with animal feces. It can cause gastrointestinal infection in humans, leading to symptoms such as diarrhea, abdominal pain, fever, and vomiting. In severe cases, it can spread beyond the intestines and cause complications like skin lesions, joint inflammation, and spread to the bloodstream (septicemia). The incubation period for Yersinia pseudotuberculosis infections is typically 5-10 days. Diagnosis is usually made through culture of the bacterium from stool or other bodily fluids, and treatment typically involves antibiotics. Prevention measures include good hygiene practices, such as proper handwashing and avoiding consumption of contaminated food and water.
'Yersinia pseudotuberculosis' is a gram-negative, facultatively anaerobic, rod-shaped bacterium that primarily causes gastrointestinal illness, often manifesting as pseudoappendicitis or enterocolitis, and can occasionally lead to systemic infection in humans and animals.
"Yersinia pseudotuberculosis" is a gram-negative, rod-shaped bacterium that is facultatively anaerobic, meaning it can grow in the presence or absence of oxygen. It is a causative agent of gastrointestinal illness in humans and animals, known as yersiniosis. The infection can cause symptoms such as diarrhea, abdominal pain, fever, and vomiting.
The bacterium is commonly found in the environment, particularly in soil and water, and can be transmitted to humans through contaminated food or water. It can also be spread through contact with infected animals, including birds and mammals.
Yersinia pseudotuberculosis is closely related to Yersinia pestis, the bacterium that causes plague, but it is generally less virulent in humans. However, in rare cases, it can cause severe illness, particularly in individuals with weakened immune systems.
Yersinia is a genus of Gram-negative, facultatively anaerobic, rod-shaped bacteria that includes several pathogenic species capable of causing various diseases in humans and animals, such as Y. pestis (plague), Y. enterocolitica (yersiniosis), and Y. pseudotuberculosis (pseudotuberculosis).
"Yersinia" is a genus of gram-negative bacteria that includes several species capable of causing human diseases. The most notable species are:
1. Yersinia pestis: This is the causative agent of plague, a severe and potentially fatal infectious disease. Plague can manifest in different forms, such as bubonic, septicemic, or pneumonic plague, depending on the route of infection. Historically, it has been associated with major pandemics like the Justinian Plague and the Black Death.
2. Yersinia pseudotuberculosis: This species is responsible for causing a gastrointestinal illness known as pseudoappendicitis or mesenteric adenitis, which can mimic appendicitis symptoms. Infection often results from consuming contaminated food or water.
3. Yersinia enterocolitica: Similar to Y. pseudotuberculosis, this species causes gastrointestinal infections, typically presenting as enterocolitis or terminal ileitis. Symptoms may include diarrhea, abdominal pain, and fever. In rare cases, it can lead to severe complications like sepsis or extraintestinal infections.
These bacteria are primarily transmitted through the fecal-oral route, either by consuming contaminated food or water or coming into contact with infected animals or their excrement. Proper hygiene practices and adequate cooking of food can help prevent Yersinia infections.
Yersinia ruckeri is a gram-negative, rod-shaped bacterium that belongs to the Enterobacteriaceae family and can cause a contagious and potentially fatal disease known as enteric redmouth (ERM) in salmonid fish species.
"Yersinia ruckeri" is a species of gram-negative bacterium that belongs to the family Enterobacteriaceae. It is the causative agent of enteric redmouth disease (ERM), a serious and often fatal infection in salmonid fish such as rainbow trout and Atlantic salmon. The bacteria can cause septicemia, hemorrhagic septicemia, and skin lesions in infected fish. It is not known to cause disease in humans or other animals.
A plague vaccine is a biological preparation developed to provide active acquired immunity against the plague, typically containing inactivated Yersinia pestis bacteria or specific antigens, which stimulate an immune response upon administration.
A plague vaccine is a type of immunization used to protect against the bacterial infection caused by Yersinia pestis, the causative agent of plague. The vaccine contains killed or weakened forms of the bacteria, which stimulate the immune system to produce antibodies and activate immune cells that can recognize and fight off the infection if the person is exposed to the bacteria in the future.
There are several types of plague vaccines available, including whole-cell killed vaccines, live attenuated vaccines, and subunit vaccines. The choice of vaccine depends on various factors, such as the target population, the route of exposure (e.g., respiratory or cutaneous), and the desired duration of immunity.
Plague vaccines have been used for many years to protect military personnel and individuals at high risk of exposure to plague, such as laboratory workers and people living in areas where plague is endemic. However, their use is not widespread, and they are not currently recommended for general use in the United States or other developed countries.
It's important to note that while plague vaccines can provide some protection against the disease, they are not 100% effective, and other measures such as antibiotics and insect control are also important for preventing and treating plague infections.
