stool examinations of 402 inhabitants of 8 villages in and around an area near zahedan, and 280 people who had emigrated from the rural area of zabol, revealed the following: the prevalence of infection with ascaris, trichuris and trichostrongylus was very low (less than 5%) in all areas surveyed, while the mean infection rates found for h.nana, hookworm and e.vermicularis (by stool examination...

The helminths of 77 nyala, Tragelaphus angasii, from 4 game reserves in Natal, were collected, counted and identified. Ten nematode species and 4 nematode genera, a trematode species and paramphistomes, and 2 cestode genera were recovered from the antelope. Of these, a Cooperia rotundispiculum race, Gaigeria pachyscelis, a Gongylonema sp., Haemonchus vegliai, Impalaia tuberculata, an Oesophagos...

Trichostrongylus is a common nematode found to infect livestock throughout the tropics and can cause accidental zoonosis in humans. In the Lao PDR and Thailand, cases of human trichostrongyliasis have been reported sporadically but clinical data are limited. We retrospectively reviewed 41 cases of trichostrongyliasis who presented to Srinagarind Hospital, Thailand from 2005 to 2012. The diagnos...

in vitro lymphocyte responses of high responder (hr) and low responder (lr) guinea pigs from pe-ripheral blood lymphocytes (pbl) to parasite antigens soluble protein third stage larvae (spl3) and soluble protein adult stage ( spa), non-parasite antigen ovalbumin (ova) were examined. there was substantial differences between hr and lr guinea pigs in the rate of acquisition of responsiveness to t...

abattoir survey was carried out to determine the prevalence of gastrointestinal helminths and the seasonal fluctuations in intestinal worm burdens and faecal worm egg counts of camel in khorasan razavi province in the northeast of iran. a total of 306 dromedaries (camelus dromedarius) in the mashhad abattoir, in the northeast of iran and the capital of khorasanprovince were examined between oct...

Abstract Background The diagnosis of gastrointestinal nematode (GIN) infections in ruminants is routinely based on morphological/morphometric analysis parasite specimens recovered by coprological methods, followed larval culture (LC) techniques. Such an approach laborious, time-consuming, requires a skilled expert, and moreover suffers from certain limitations. Molecular tools are able to overc...

Twelve Bonsmara tracer calves (aged 6-12 months) were used to monitor helminth infections in the communal farming system of Botshabelo in the Free State. One calve was slaughtered each month from December 1995 to November 1996 and processed for helminth recovery. All the calves harboured worms, but the numbers were always low. The order of prevalence of the major parasites was Trichostrongylus ...

A strain of Trichostrongylus colubriformis from Nottingham Road, in Natal, was found to be solidly resistant to levamisole and morantel at the recommended dose levels. Untreated control sheep in fact harboured fewer worms at slaughter than either of the 2 treated groups. In contrast, the benzimidazoles and ivermectin were more than 99.9% effective against this worm strain. The possible implicat...
