tactical treatment with copper oxide wire particles and symptomatic levamisole treatment using the famacha(©) system in indigenous goats in south africa.haemonchosis is considered to be the most economically important gastrointestinal disease of small ruminants in the tropics and subtropics. however, chemical anthelmintics, which were the mainstay of control, have been compromised by a high prevalence of resistance worldwide. copper oxide wire particles (cowp) have been shown to have anthelmintic effects, but few studies have examined their use under field conditions. the use of cowp was therefore evaluated as a tactical anthelmintic treatment i ...201121880430
parasites of south african wildlife. iii. helminths of common reedbuck, redunca arundinum, in natal.twenty-six common reedbuck, redunca arundinum, were shot in pairs at monthly intervals for 13 consecutive months in the himeville region of natal. ten nematode species, 2 cestodes and 1 trematode were recovered from these animals. cooperia yoshidai was both the most numerous and most prevalent worm and peak burdens occurred during summer. thirty-one reedbuck, killed at different intervals in various localities within the st. lucia reserve, harboured between 4 and 11 nematode species, 1 cestode a ...19892726193
how long before resistance makes it impossible to control some field strains of haemonchus contortus in south africa with any of the modern anthelmintics?this paper describes an exceptional spectrum of multiple anthelmintic resistance in two strains of haemonchus contortus in south africa, one from howick in kwazulu-natal, and the other from badplaas, in mpumalanga. apparently for the first time, a helminth strain is described with resistance to compounds from all five of the modern anthelmintic groups used for nematode control in sheep; also, two strains of h. contortus show resistance to the two substituted phenols, dinitrophenol and nitroxynil ...19979195715
the helminths of various antelope species from natal.helminth parasites were collected from 2 bushbuck, tragelaphus scriptus, 2 red duiker, cephalophus natalensis, 1 oribi, ourebia ourebi, and 4 reedbuck, redunca arundinum, that died or were culled in various parts of natal. one trematode genus, 1 cestode genus and 12 nematode species were recovered. haemonchus contortus. ostertagia harrisi, trichostrongylus capricola, trichostrongylus vitrinus, cooperia rotundispiculum and setaria scalprum are new parasite records for the red duiker. trichostrong ...19846241958
