The parasite load of brown hares (Lepus europaeus) is of great interest to hunting ground managers and veterinarians. We compared the prevalence and intensity of parasitic infections in 362 hares from Austria and the Czech Republic with respect to age and body weight. Samples of the entire gastrointestinal tract, liver and lungs were collected during autumn hunting events in 2007. The parasite ...

At monthly intervals for periods ranging from 9 to 25 consecutive months between three and four Merino yearling-sheep and two Merino lambs on three farms in Eastern Cape Thornveld, and two Dorper yearling-sheep on a farm in Valley Bushveld were slaughtered and examined for helminths. The Merino sheep were infected with 15 nematode species, of which Haemonchus contortus, Nematodirus spathiger an...

Every few years a large proportion of the feral sheep on Hirta, St Kilda die due to food shortage. The effects of malnutrition are exacerbated by gastrointestinal nematodes. As found in sheep flocks in mainland Britain, Teladorsagia circumcincta has long been considered the predominant and most pathogenic nematode species in all age classes of Soay sheep. Previous research indicated that intens...

An observational study was performed to investigate the effects of yarding and ruminoreticulum bypass on the ef®cacy of oxfendazole against resistant Trichostrongylus spp. helminths. Ruminoreticulum bypass was observed in 9-month old Perendale lambs using video-taped ̄uoroscopy and the ef®cacy of oxfendazole was estimated using the faecal egg count reduction test. Yarding and withholding feed f...

Helminth parasites were collected from 13 grysbok, Raphicerus melanotis, 12 common duikers, Sylvicapra grimmia, 24 Angora goats and 24 Boer goats killed on a farm in Valley Bushveld in the eastern Cape Province. Nematodes belonging to 9 species and a further 2 genera and cestodes belonging to 1 species and a further genus were recovered from the grysbok. Of these, worms of the genus Skrjabinema...

Trichostrongylids infection has gained significant public health importance since Trichostrongylus spp. infections have been reported in humans in Lao PDR. In this study, gastrointestinal nematodes were identified and the intensity of infections was determined in goats and cattle, which are animals greatly used for meat production in Lahanam Village, Lao PDR. The total number of goats and bovin...

The cumulative total helminth parasite burdens of ranch calves during their first seven months of life on the North-eastern Mountain Grassland of South Africa were determined during two consecutive years. Trichostrongylus axei was the most abundant nematode parasite followed by Cooperia spp. and Ostertagia ostertagi. Haemonchus spp. occurred in relatively low numbers and its development was sig...

the effect of phenylen di-isothiocyanate (jonit) in the mass treatment of various intestinal helminthiases was evaluated among the inhabitants of a village in dezful, southwest iran. stool samples collected and examined from 17 persons showed infection rates of 80% for ancylostoma duodenale, 57.3% for ascaris, 46.7% for trichostronylus spp. and 22.8% for h. nana.seventy- one persons (41 childre...

The seasonal incidence of helminth infestation on a farm in the Transvaal Highveld was determined by the slaughter of tracer lambs exposed on pasture for periods of approximately 6 weeks. Haemonchus contortus, the most prevalent nematode, was recovered in the greatest numbers from January--May 1974. Peak counts of Ostertagia circumcincta were made during March and April 1974 and in January 1975...
