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 at weaning in october 1987 this species was superseded by teladorsagia circumcincta and trichostrongylus rugatus.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 ... | 1989 | 2487725 |
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, ... | 1989 | 2626260 |

characterization of trichuris skrjabini by isoenzyme gel electrophoresis: comparative study with trichuris ovis. | morphological and biometric studies were performed in trichuris skrjabini (baskakov, 1924) collected from the caecum of capra hircus. the ldh (ec 1.1.1.27.), g6pd (ec 1.1.1.49.), gpi (ec 5.3.1.9.), mdh (ec 1.1.1.37) and malic enzyme (me) (ec 1.1.1.40) isoenzymatic patterns of t. skrjabini were determined by starch gel electrophoresis. the g6pd and gpi isoenzymatic patterns of t. skrjabini displayed two anodic bands for both enzymes: one fast migration band and one band near the origin. this isoe ... | 1996 | 8988307 |
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 ... | 2004 | 15270116 |
molecular identification of trichuris vulpis and trichuris suis isolated from different hosts. | trichuris suis was isolated from the cecum of two different hosts (sus scrofa domestica -- swine and sus scrofa scrofa -- wild boar) and trichuris vulpis from dogs in sevilla, spain. genomic dna was isolated and internal transcribed spacers (its)1-5.8s-its2 segment from the ribosomal dna (rdna) was amplified and sequenced using polymerase chain reaction techniques. the sequence of t. suis from both hosts was 1,396 bp in length while that of t. vulpis was 1,044 bp. its1 of both populations isolat ... | 2007 | 17004099 |
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, ... | 2008 | 18766377 |
cytochrome oxidase subunit 1 and mitochondrial 16s rdna sequences of trichuris skrjabini (tricocephalida: trichuridae). | the partial mitochondrial cytochrome c-oxidase subunit 1 gene (cox 1) and partial mitochondrial 16s ribosomal dna of trichuris skrjabini (baskakov 1924) isolated from capra hircus have been amplified and sequenced. the analyses of multiple sequence alignments of mitochondrial 16s rdna and cox 1 of t. skrjabini revealed high homology with those of trichinella species. for the first time, the mitochondrial dna gene sequences of one species of trichurid nematode have been cited. | 2009 | 19039605 |
16S partial gene mitochondrial DNA and internal transcribed spacers ribosomal DNA as differential markers of Trichuris discolor populations. | Comparative morphological, biometrical and molecular studies of Trichuris discolor isolated from Bos taurus from Spain and Iran was carried out. Furthermore, Trichuris ovis isolated from B. taurus and Capra hircus from Spain has been, molecularly, analyzed. Morphological studies revealed clear differences between T. ovis and T. discolor isolated from B. taurus but differences were not observed between populations of T. discolor isolated from different geographical regions. Nevertheless, the mole ... | 2011 | 22136768 |
the efficacy of eprinomectin extended-release injection against naturally acquired nematode parasites of cattle, with special regard to inhibited fourth-stage ostertagia larvae. | the efficacy of eprinomectin in an extended-release injection (eri) formulation in the treatment of cattle harboring naturally acquired nematode populations (including inhibited nematodes) was evaluated. five studies were conducted under a similar protocol in the usa, the uk, and in germany. all study animals were infected by grazing naturally contaminated pastures. the adequacy of pasture infectivity was confirmed by examining tracer calves prior to allocation and treatment of the study animals ... | 2012 | 23273781 |
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 ... | 2015 | 26070887 |
