Identification of candidate antigens from adult stages of Toxocara canis for the serodiagnosis of human toxocariasis. In the present work, we identified adult Toxocara canis antigens through sodium dodecyl sulfate-polyacrylamide gel electrophoresis for potential use in human toxocariasis immunodiagnosis. The sensitivity and specificity of several semi-purified antigens, as well as their cross-reactivity with other parasitic infections, were assessed by IgM and IgG-enzime linked immunosorbent assay.
Toxocara cati Schrank, Brumpt, Goeze illustrated a worm from the cat that had large cervical alae. Schrank gave this worm the name Ascaris cati.
Toxocara canis also known as dog roundworm is a worldwide-distributed helminth parasite of dogs and other canids. The name is derived from the Greek word "toxon," meaning bow or quiver, and the Latin word "caro," meaning flesh. In adult dogs, the infection is usually asymptomatic but may be characterized by diarrhea.
Toxcocara canis has a worldwide distribution. It is prevalent in all locations that have domestic dogs, puppies, and other canids. Toxocara canis is also found in places that have other various mammals such as mice, pigs, birds, and foxes, but these hosts are only paratenic hosts. Hosts are terrestrial mammals and therefore T.
Toxocariasis in humans is caused by infection with larvae of Toxocara spp. Confirmed zoonotic species include the dog roundworm T. It is not known whether other closely-related Toxocara species can infect humans e.
Toxocariasis is a zoonosis caused by the Toxocara canis and Toxocara cati nematodes larvae. These are intestinal parasites found in canids and felids, respectively. Retinal detachment in the left eye was diagnosed by ultrasound.
Because larvae are difficult to detect in tissues, diagnosis is mostly based on serology. Non specific reactions are observed mainly due to cross-reactivity with Ascaris sp antigens. For that, the rabbit IgG was previously absorbed by Ascaris suum adult antigens.
Roundworms are nematodes that can infect domestic and wild canids and felids. Animals become infected when they ingest eggs containing infective larvae. Toxocara canis primarily affects puppies, producing signs of enteritis, and it is zoonotic.

To reduce environmental contamination with Toxocara canis eggs, the current general advice is to deworm all dogs older than six months on average four times a year. However, only a small proportion of non-juvenile household dogs actually shed T. The identification of these frequent shedders and the associated risk factors is an important cornerstone for constructing evidence-based deworming regimens. The purpose of this study is to identify risk factors associated with recurrence of periods of shedding Toxocara eggs in a cohort of household dogs older than six months.
