During a survey of the parasites of antelope in the Bontebok National Park, Swellendam, Cape Province, specimens of Haemonchus contortus with exceptionally long spicules were recovered from 5 out of 8 bontebok, Damaliscus dorcas dorcas, and 3 out of 5 vaal ribbok, Pelea capreolus, but not from 4 springbok, Antidorcas marsupialis. Typically, H. contortus has spicules 0,466 +/- 0,085 mm long, but...

The population health of endangered Key deer (Odocoileus virginianus clavium) was monitored from 10 February 1986 to 28 September 2000 by necropsy of animals that were killed by vehicles, euthanized because of terminal injuries or disease conditions, or found dead. The predominant mortality factor during the period was collision with motor vehicles; however, several infectious diseases were dia...

A study on the influence of gastrointestinal trichostrongyles on ram fertility was performed. Two groups of semen donor rams (Sarda breed) were utilized; one was experimentally infected with Haemonchus contortus, Trichostrongylus colubriformis and Teladorsagia circumcincta and the other was used as a control group. In all animals, coprological, haematological and reproductive parameters were st...

Previous work has shown that a protein extract enriched for cysteine protease activity (TSBP) prepared from adult Haemonchus contortus using thiol sepharose affinity chromatography confers substantial protection against a single challenge infection. TSBP comprised proteases and other proteins. Here, TSBP were further fractionated using anion-exchange chromatography and fractions pooled on the b...

background: cross antigenicity is the major problem in developing a reliable tool for immunodiagnosis and immunoprophylaxis of parasitic diseases. mixed infection due to different types of gastrointestinal parasites is more common than single species infection under field condition. methods: the present study was undertaken to detect antigenic cross-reactivity among haemonchus contortus, oesoph...

The prevalence of gastrointestinal (GI) parasites and the efficacy of Dectomax (Doramectin) against these parasites was studied. For this purpose, 50 camels were selected from different localities of Faisalabad, their faecal samples were collected and examined for the parasitism. The overall prevalence of G1 parasites was 60%. Species wise prevalence of these parasites was: 20, 14, 8, 4, 4 and ...

Chemotherapy remains the foremost available tool for the control of nematode parasites. However, the substantial use of anthelmintics, combined with a scarcity of new anthelmintic classes, has led to a gradual increase in the resistance of nematode parasites to these compounds. Multi-Drug Resistance (MDR) in economically important livestock nematodes, such as Haemonchus contortus enables the pa...
