Abstract:
... The usefulness of a human enzyme-linked immunosorbent assay (ELISA) for serological diagnosis of Baylisascaris procyonis larva migrans was assessed in nonhuman primates (NHP). The test was originally developed as an assay performed on human samples at Purdue University. Six participating zoos submitted 258 NHP serum samples, spanning these major phylogenetic groups: 1) great apes (n = 84), 2) less ...

Abstract:
... Ascarid Larva Migrans Syndrome (ascarid LMS) is a clinical syndrome in humans, caused by the migration of animal roundworm larvae such as Toxocara canis, Toxocara cati and Ascaris suum. Humans may acquire infection by ingesting embryonated eggs, or infective larvae of these parasites in contaminated meat and organ meats. To detect these pathogenic contaminations, a novel nested multiplex PCR syste ...

Abstract:
... A total of 10 species of Baylisascaris, a genus of ascaridoid nematodes, occur worldwide and 6 of them occur in the New World. Most of the Baylisascaris species have a similar life cycle with carnivorous mammals or marsupials serving as definitive hosts and a smaller prey host serving as paratenic (or intermediate) hosts. However, one species in rodents is unique in that it only has one host. Cons ...

Abstract:
... Baylisascaris procyonis is a nematode whose definitive host is the raccoon (Procyon lotor). Adult parasites are not particularly pathogenic to raccoons; however, larvae in intermediate hosts can cause visceral, ocular, and neural larva migrans. Humans serve as dead-end hosts, and pathological responses are similar to those found in infected intermediate hosts. Infected raccoons expose intermediate ...

In East Asia, ascarid LMS has been considered as a food‐borne disease in adulthood who has the dietary habitat of consuming raw or lightly cooked meat and organ meats. To evaluate the potential risk of A. suum infection from these foods, Ascaris specific real‐time PCR was developed. The assay could ...

Abstract:
... BACKGROUND: Toxocara canis is a nematode that parasitizes dogs, while humans are paratenic hosts. When humans are infected the migrating larvae damage the liver, lungs and even the nervous system. Larva migrans diagnosis is based on immunological techniques; however, the commercial immunodiagnostic kits detect anti-T. canis antibodies which may cross-react with other parasites, mainly nematodes wi ...

Abstract:
... Toxocara canis is regarded as the main cause of human toxocarosis but the relative contribution of T. cati is probably underestimated; serological and other diagnostic methods used in most studies of this zoonotic disease do not distinguish between the two parasites.
