anti-toxocara spp. antibodies in sheep from southeastern brazil.the purpose of this study was to evaluate the frequency of anti-toxocara antibodies in sheep from presidente prudente, southeastern brazil. serum samples were obtained from 365 sheep of diverse breeds and different ages. samples were collected at a slaughterhouse and at farms located in presidente prudente. three groups of animal of different ages were evaluated according to age: group i: between 1 and 6 months old; group ii: between 7 and 10 months old; and group iii: between 11 and 15 months o ...201121330057
seroprevalence of toxocara canis in sheep in wales.antibody levels to toxocara canis l2 excretory/secretory antigens were examined by elisa in 400 serum samples from sheep in powys and gwent, wales. a positive od value was set at the mean +/-3s.d. of 45 control samples. seroprevalence increased with age. seven percent and 13% of 6-month-old sheep showed positive od values as did 16% of 10-month-old, 27% and 31% of 15-month-old and 47% of cull ewes. analysis of variance showed a significant increase in elisa od values among the seropositive sheep ...200616500027

larval toxocarosis in sheep: the immunohistochemical characterization of lesions in some affected organs.morphological and immunohistochemical responses of lambs following oral infection with 10,000 infective toxocara canis (t. canis) eggs were studied up to 28 days post-infection (pi). the small intestine, liver, lungs and brain of both infected and control lambs were examined using the routine histological methods for paraffin sections and immunohistochemical techniques for frozen tissue sections. eosinophil-rich hepatic granulomas and diffuse t. canis-induced pulmonary inflammation were the most ...200211934460
the effects of benzimidazoles on the larval stage of toxocara cati in experimentally infected chickens.toxocara cati (t. cati) and toxocara canis (t. canis), roundworms of cats and dogs, are zoonotic parasites that cause visceral and ocular larval migrans in human beings. humans and other paratenic hosts are infected by ingesting the infective toxocara eggs from contaminated soil, unwashed hands, contaminated raw vegetables or ingestion of under-cooked organs and muscle tissues of infected paratenic hosts such as chickens, cattle and sheep. it has been shown that the seroprevalence of toxocariasi ...200919696725
