[distribution of nematode parasites of the digestive system in sheep (ovis aries) and goats (capra hircus) of the piedmontese and valdostano alpine arc].a survey, carried out on gastro-intestinal nematodes of sheep and goats of piemonte and of valle d'aosta (87 sheep and 12 goats) has shown the presence of the following species in sheep, bunostomum trigonocephalum, chabertia ovina, cooperia curticei, haemonchus contortus, marshallagia marshalli, nematodirus abnormalis, nematodirus filicollis, nematodirus helvetianus, nematodirus spathiger, oesophagostomum venulosum, ostertagia circumcincta, ostertagia lyrata, ostertagia trifurcata, skrjabinema o ...1977572958
linear distribution of nematodes in the gastrointestinal tract of tracer lambs.forty-eight tracer lambs were killed in 2004-2007. the abomasum, duodenum, small intestine (jejunum and ileum), colon and caecum were collected and processed for parasites enumeration and identification-mucosal scrapings of both abomasums and intestines were digested. out of 48 gastrointestinal tracts examined, all were found to be positive for nematode infection. seventeen species of gastrointestinal nematodes were recovered: bunostomum trigonocephalum, cooperia curticei, haemonchus contortus, ...200818766377
taxonomy and phylogeny of trichuris globulosa von linstow, 1901 from camels. a review of trichuris species parasitizing herbivorous.at the present work, we carried out a morph-biometrical and molecular study of trichuris species isolated from camelus dromedarius from iran and from ovis aries from south africa comparatively with other species of trichuris from different herbivorous hosts and geographical regions. the population from camels from iran was identified as trichuris globulosa. two different morphometrically populations of trichuris sp. from sheep from south africa were identified: trichuris ovis and trichuris skrja ...201526070887
determination of trichuris skrjabini by sequencing of the its1-5.8s-its2 segment of the ribosomal dna: comparative molecular study of different species of trichurids.adults of trichuris skrjahini have been isolated from the cecum of caprine hosts (capra hircus), trichuris ovis and trichuris globulosa from ovis aries (sheep) and c. hircus (goats), and trichuris leporis from lepus europaeus (rabbits) in spain. genomic dna was isolated and the its1-5.8s-its2 segment from the ribosomal dna (rdna) was amplified and sequenced by polymerase chain reaction (pcr) techniques. the its1 of t. skrjabini, t. ovis, t. globulosa, and t. leporis was 495, 757, 757, and 536 nu ...200415270116
availability of infective larvae of parasitic nematodes of sheep grazing on kikuyu (pennisetum clandestinum) pastures in the winter rainfall area.thirteen groups of 4 south african mutton merinos grazed for 4 weeks with the flock on kikuyu pastures and were slaughtered for total and differential worm counts at necropsy. subsequently 12 groups of 8 week tracers grazed on the pastures and were killed for worm counts post mortem. the following were present in most sheep: teladorsagia (syn. ostertagia) circumcincta, trichostrongylus axei, trichostrongylus colubriformis, dictyocaulus filaria and oesophagostomum venulosum. haemonchus contortus, ...19892626260
overberg research projects. i. the epidemiology of parasitic nematodes in ewes, suckling lambs and weaners.total differential warm counts were done on sheep slaughtered from 7 may 1987 to 19 may 1988 at boontjieskraal estate in the overberg, republic of south africa. it was found that winter lambs became infested with nematodirus spathiger at 5 to 7 weeks of age. at weaning in october 1987 this species was superseded by teladorsagia circumcincta and trichostrongylus rugatus. small numbers of trichuris skrjabini and oesophagostomum venulosum were also present. from july to october, 3rd and 4th stage l ...19892487725
