A case of gastric pseudoterranoviasis in a 43-year-old man in Korea. (1/38)
A case of Pseudoterranova decipiens infection was found in a 43-year-old man by gastroendoscopic examination on August 20, 1996. On August 6, 1996, he visited a local clinic, complaining of epigastric pain two days after eating raw marine fishes. Although the symptoms were relieved soon, endoscopic examination was done for differential diagnosis. A white, live nematode larva was removed from the fundus of the stomach. The larva was 38.3 x 1.0 mm in size and had a cecum reaching to the mid-level of the ventriculus. A lot of transverse striations were regularly arranged on the cuticle of its body surface, but the boring tooth and mucron were not observed at both ends of the worm. The worm was identified as the 4th stage larva of P. decipiens. (+info)Plasma and bile antibodies of the teleost Trematomus bernacchii specific for the nematode Pseudoterranova decipiens. (2/38)
We investigated the occurrence of antibodies against protein antigens of the nematode parasite Pseudoterranova decipiens in the plasma and bile of the Antarctic teleost Trematomus bernacchii. Three different P. decipiens protein solutions were prepared: excreted/secreted proteins from live larvae (ESP); surface-associated proteins obtained by mild extraction of larval bodies (SAP); and cuticular soluble proteins recovered by extraction in strong reducing conditions (CSP). Using different immunoassays, these 3 preparations were tested for their ability to bind fish antibody. As determined by ELISA, the specific antibody binding activity was higher in SAP than in CSP. As determined by dot-blot immunoassay, the specific antigen binding activity versus SAP was higher in bile than in plasma antibodies. A different number of antigenic components of SAP and ESP were identified by immunoblotting performed with plasma or bile antibodies. These results led to the conclusion that T. bernacchii parasitism by nematodes involves plasma and bile anti-parasite antibodies. Furthermore bile antibodies were found to be more reactive and more heterogeneous than plasma. (+info)Larvae of Contracaecum sp. among inshore fish species of southwestern Australia. (3/38)
Larval nematode infections were investigated in 236 fish from 17 estuarine and near-shore species in southwestern Australia. Larvae of the genus Contracaecum were found in 4 species of fish (Acanthopagrus butcheri, Sillaginodes punctata, Mugil cephalus and Aldrichetta forsteri). The prevalence and intensity of infection was highest in the 2 species of mullet: 81% infected and 9.8 +/- 1.5 larvae fish(-1) for M. cephalus; 100% and 12.7 +/- 3.7 larvae fish(-1) for A. forsteri. There was no evidence of post-mortem migration of worms from the visceral organs to the musculature of the fish. (+info)Experimental heteroxenous cycle of Lagochilascaris minor Leiper, 1909 (Nematoda: Ascarididae) in white mice and in cats. (4/38)
Reports of natural infections of sylvatic carnivores by adult worms of species similar to Lagochilascaris minor in the Neotropical region led to attempts to establish experimental cycles in laboratory mice and in cats. Also, larval development was seen in the skeletal muscle of an agouti (Dasyprocta leporina) infected per os with incubated eggs of the parasite obtained from a human case. In cats, adult worms develop and fertile eggs are expelled in the feces; in mice, larval stages of the parasite develop, and are encapsulate in the skeletal muscle, and in the adipose and subcutaneous connective tissue. From our observations, we conclude that the larva infective for the mouse is the early 3rd stage, while for the final host the infective form is the later 3rd stage. A single moult was seen in the mouse, giving rise to a small population of 4th stage larvae, long after the initial infection. (+info)Raccoon roundworm eggs near homes and risk for larva migrans disease, California communities. (5/38)
The raccoon roundworm, Baylisascaris procyonis, is increasingly recognized as a cause of serious or fatal larva migrans disease in humans and animals. We assessed the potential for infection in three northern California communities by determining the density and distribution of raccoon latrines, where transmission primarily occurs, and the prevalence of eggs at private residences. We collected fecal samples from 215 latrines and found that 44%-53% of the latrines contained B. procyonis eggs and that 16%-32% contained infective eggs. Among the properties surveyed, 28%-49% harbored at least one latrine that was positive for B. procyonis eggs. The latrine densities in these communities were higher than any previously reported. The presence of B. procyonis eggs in raccoon latrines was common, widespread, and closely associated with human habitation. Where raccoon densities are high, education of the public and removal of raccoons may be necessary. (+info)A new nematode species Goezia leporini n. sp. (Anisakidae) from cultured freshwater fish Leporinus macrocephalus (Anostomidae) in Brazil. (6/38)
This paper describes nematode infection in the cultured freshwater fish Leporinus macrocephalus (Osteichthyses: Anostomidae) collected at Batatais, Sao Paulo State, Brazil. Of a total of 32 examined fish, 21 (65%) were infected with Goezia leporini n. sp. (Nematoda: Anisakidae) with mean infection intensity of 4.1 parasites. The nematodes presented total length greater than G intermedia, G. holmesi, G. pelagia, G. minuta, G. kliksi, G. sinamora, G. nonipapillata, G. alii, G. moraveci, G. brasiliensis, and G. brevicaeca. The main difference was a great number of preanal papillae in males when compared to G. brasiliensis and G. brevicaeca. The present description also differs from that of G. brasiliensis with respect to spicule length and distance of vulva from the anterior extremity. (+info)Gastrointestinal impaction by Parascaris equorum in a Thoroughbred foal in Jeju, Korea. (7/38)
A weanling Thoroughbred foal was admitted to Equine Hospital, Korea Racing Association with signs of colic. On admission the foal was sweating profusely, appeared anxious and exhibiting signs suggestive of abdominal pain. Clinical examination revealed: tachycardia (90 beats/min), tachypnea (50 breaths/min) and congested and slightly cyanotic mucous membranes. No intestinal sounds were auscultated in all 4 abdominal quadrants. Rectal palpation identified concurrent cecum and large colon impactions. Treatment consisted of intravenous administration of a balanced electrolyte solution, nasogastric siphonage and administration of analgesics. Nasogastric reflux contained ascarids. This treatment failed to alleviate the signs of colic. The foal died 3 hours later following discharge because the owner didn't want laparatomy because of economic constraints. Prior to admission this foal had not received any prophylactic anthelmintic treatment. In necropsy, there were masses of ascarids accumulation in the stomach, small intestine and large intestine. The outcome of this report is to describe the first diagnosed case of gastrointestinal impaction by P. equorum in a Thoroughbred foal in South Korea and indicates the importance of regular anthelmintic treatment. (+info)Baylisascariasis. (8/38)
The raccoon roundworm, Baylisascaris procyonis, is the most common and widespread cause of clinical larva migrans in animals. In addition, it is increasingly recognized as a cause of devastating or fatal neural larva migrans in infants and young children and ocular larva migrans in adults. Humans become infected by accidentally ingesting infective B. procyonis eggs from raccoon latrines or articles contaminated with their feces. Two features distinguish B. procyonis from other helminthes that cause larva migrans: (i) its aggressive somatic migration and invasion of the central nervous system and (ii) the continued growth of larvae to a large size within the central nervous system. Typically, B. procyonis neural larva migrans presents as acute fulminant eosinophilic meningoencephalitis. Once invasion of the central nervous system has occurred, the prognosis is grave with or without treatment. To date, despite anthelmintic treatment of cases of B. procyonis neural larva migrans, there are no documented neurologically intact survivors. Epidemiologic study of human cases of neural larva migrans demonstrate that contact with raccoon feces or an environment contaminated by infective eggs and geophagia or pica are the most important risk factors for infection. In many regions of the United States, increasingly large populations of raccoons, with high rates of B. procyonis infection, live in close proximity to humans. Although documented cases of human baylisascariasis remain relatively uncommon, widespread contamination of the domestic environment by infected raccoons suggests that the risk of exposure and human infection is probably substantial. In the absence of early diagnosis or effective treatment, prevention of infection is the most important public health measure. (+info)Ascaridida infections are caused by roundworms belonging to the order Ascaridida, which includes several species that can infect humans and animals. The most common species that infects humans is Ascaris lumbricoides, also known as the human roundworm. Other species that can cause infection in humans include Toxocara spp., Baylisascaris procyonis, and Ascaris suum (the pig roundworm).
Infection with these parasites typically occurs through ingestion of contaminated food or water containing eggs or larvae. The larvae hatch in the small intestine and then migrate through the body to various organs, including the liver, lungs, and eyes, where they can cause damage. After several weeks, the larvae return to the small intestine, where they mature into adult worms and begin producing eggs.
Symptoms of ascariasis (infection with Ascaris lumbricoides) can vary depending on the severity of the infection and the location of the worms in the body. Mild infections may cause no symptoms or only mild gastrointestinal symptoms such as abdominal pain, nausea, and diarrhea. More severe infections can lead to intestinal obstruction, malnutrition, and other complications.
Infection with Toxocara spp. can cause a condition called visceral larva migrans, which is characterized by fever, cough, rash, and liver enlargement. Ocular larva migrans can occur when the larvae migrate to the eye, causing inflammation and potentially leading to vision loss.
Baylisascaris procyonis infection can cause a similar condition called neural larva migrans, which can lead to neurological symptoms such as seizures, muscle weakness, and paralysis.
Prevention of Ascaridida infections involves practicing good hygiene, including washing hands thoroughly with soap and water after using the toilet or handling soil or contaminated objects. Proper cooking and cleaning of food can also help prevent infection. In areas where ascariasis is common, treatment of human waste and improvement of sanitation infrastructure can help reduce transmission.
Ascaridida is an order of large, parasitic roundworms that belong to the phylum Nematoda. These worms are known to infect a wide range of hosts, including humans, and can cause significant damage to their host's health. The most well-known species in this order is Ascaris lumbricoides, which is the causative agent of ascariasis in humans.
Ascariasis is a common parasitic infection that affects millions of people worldwide, particularly in areas with poor sanitation and hygiene. The life cycle of Ascaris lumbricoides involves the ingestion of eggs present in contaminated food or water. Once inside the human body, the larvae hatch from the eggs and migrate through the lungs, where they mature into adult worms that can grow up to 15 inches long. The adult worms then lay thousands of eggs that are passed through the feces, perpetuating the life cycle.
Symptoms of ascariasis can range from mild to severe and may include abdominal pain, nausea, vomiting, diarrhea, and coughing. In severe cases, the worms can cause intestinal obstruction or perforation, which can be life-threatening if left untreated.
Prevention of ascariasis involves practicing good hygiene and sanitation, including washing hands thoroughly with soap and water before eating or preparing food, avoiding contact with contaminated soil or water, and cooking food thoroughly. Treatment typically involves the use of anti-parasitic drugs that kill the worms and their eggs.
