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...

All of the 111 baboons examined from the Loskop Dam, Suikerbosrand and Scrutton Nature Reserves and the Sabie-Tweefontein Forest Reserve were infested with helminths of the digestive tract. The helminths recovered were Bertiella studeri, Enterobius vermicularis, Oesophagostomum bifurcum, Physaloptera caucasica, Streptopharagus pigmentatus, Strongyloides fülleborni, Trichostrongylus falculatus, ...

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 ...

The role of cholecystokinin (CCK) in modulating feed intake depression in parasite-infected lambs was investigated using CCK receptor antagonists (L364-718 and loxiglumide). Four experiments were carried out using ewe lambs infected with 4000 Trichostrongylus colubriformis larvae/d or non-infected controls (n8, live weight 25 kg). Animals were fed daily on a nutritionally complete pelleted diet...

A total of 145 scrub hares from three localities in the Kruger National Park were examined for helminths: 124 at Skukuza, 15 at Shingwedzi, and three each at Pretoriuskop and Pafuri. Trichostrongylus deflexus was the most prevalent and most abundant nematode, and was collected from hares from all four localities. Trichostrongylus falculatus was present in three localities. Trichostrongylus thom...

Two doses of infective larvae of 20 000 Trichostrongylus axei, dosed to Merino lambs at an interval of 14 days and subsequently challenged with Ostertagia circumcincta, caused a significant reduction (P less than 0.01) in the establishment of 5th and adult stages of the latter. T. axei was unable to protect Merino sheep against homologous challenge nor was Haemonchus contortus a successful vacc...

the effect of a new anthelmintic compound, leavo-tetramisole, in the mass-treatment of several intestinal helminthes has been evaluated during a study undertaken among the population of the village of zavieh hajian, located about 10 km northwest of dezful, khuzestan.in the autumn of 1972, a total of 83 inhabitants, 65 of whom were simultaneously infected with ascaris, hookworm (ancylostoma) and...

Mortality due to strongyles infection in small ruminants is a critical component of flock productivity in a tropical climate. In goat production, few experiments have been conducted to estimate the variability of this trait. A survival analysis study was carried out in the Creole experimental flock of INRA-Gardel (Moule, Guadeloupe) to identify management and genetic factors influencing mortali...
