Since Wilder (I950) described nematode endophthalmitis in patients previously diagnosed as cases of pseudoglioma, and Nichols (1956) identified the nematode as Toxocara canis, it has been recognized that this organism, which is very common in puppies all over the world, is liable to infect the human eye, particularly in young children. Ashton (I960) demonstrated the pathology of the condition. ...

Biological control is considered one of the most used alternative measures to combat helminths relevance in veterinary medicine and public health. Among these parasites, Toxocara canis stands out for its high prevalence worldwide distribution, addition being main cause visceral larva migrans man. The present work aimed fungus Pochonia chlamydosporia (isolate Pc-10) on eggs T. canis. In order do...

Eggs of Toxocara cati were found in the feces of Didelphis albiventris from a peridomestic urban environment in Brazil. Negative fecal tests following short-term captivity of the opossums, as well as the absence of ascaridids during necropsy, suggest the occurrence of pseudoparasitism. Implications of the findings for the epidemiology of toxocariasis are discussed.

background: human toxocariasis is contained in the list of neglected diseases. the infection occurs after ingestion of embryonated eggs in contaminated soil. the present study was carried out to estimate the extent of soil contamination with toxocara spp. eggs in the public places. methods: soil samples were collected randomly from 41 public places in various parts in and around of ardabil, ira...

BACKGROUND Human toxocariasis is a parasitic zoonosis with a worldwide distribution but is underdiagnosed with an underestimated impact on human health. The ingestion of embryonated eggs of Toxocara spp. present on the hands or in contaminated food or water is the main mode of infection. The only record of Toxocara congenital infection in humans occurred in a premature infant. Helminth infectio...

Zoonotic Toxocara eggs are excreted by dogs and cats. A ubiquitous distribution and resistance may lead to human, mainly children, accidental ingestion of embryonated eggs and infection. In humans the infection remains occult, often resulting in disease caused by the migration larval stages. Human infection by Toxocara canis or Toxocara cati may progress to systemic and ocular toxocariasis. Spe...

strongly positive for toxocariasis. Enzyme-linked immuno-sorbent assay for toxocaral antibodies showed 2.7 U (>1.1). Antinuclear, antineutrophil cytoplasmic antibodies, cryoglo-bulins and immune complexes were all negative. Computed tomography scans of the lungs, brain and abdomen were unremarkable. A bone marrow aspirate and biopsy revealed increased cell infiltration of the bone marrow with t...
