We have examined the global population genetic structure of Haemonchus contortus. The genetic variability was studied using both amplified fragment length polymorphism (AFLP) and nad4 sequences of the mitochondrial genome. To examine the performance and information content of the two different marker systems, comparative assessment of population genetic diversity was undertaken in 19 isolates o...

Background and Aim: Seeds from Carica pubescens were observed to be abundant as waste. This waste contains active plant compounds whose utilization has not been studied in the livestock sector. study was conducted evaluate potential of an aqueous seed extract (ASE) anthelmintic agent during rumen fermentation methane reduction. Materials Methods: Aqueous prepared C. cultivated Wonosobo, Indones...

Infective larvae (L3) of a strain of benzimidazole-resistant Haemonchus contortus were stored in the gas phase of liquid nitrogen, thawed and used to infest worm-free sheep from which, in turn, larvae were cultured, frozen and thawed. This cycle was repeated 5 times. Thereafter, the progeny of the cryopreserved larvae were compared with the progeny of the original untreated larvae for susceptib...

Sixty plant species were collected in the Ivory Coast on the basis of an ethnobotanical literature using the following three criteria: activity against worms, diarrhoea and/or abdominal pain. Eighty six plant extracts were prepared using 90% ethanol and tested for potential anthelminthic activities with a larvicidal test of Haemonchus contortus. 25.6% of the extracts showed a high activity, 12....

To determine association of grassland with parasitic diseases of livestock in Bangladesh, the 'Tracer' animals (two cow calves and two goats) were released for a month in a grassland used for communal grazing of livestock near school premise in Kanthal, Trishal, Mymensingh, Bangladesh. After slaughtering of the tracer animals, their gastrointestinal tract examination revealed six species of nem...

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, ...

Mapping and modelling helminth infections in cattle and sheep in Europe through advanced geospatial research was one of the main task of GLOWORM, a three year project (2012-2014) funded under the European Commission's (EC) seventh framework programme (FP7). Liver flukes as Fasciola hepatica and gastrointestinal nematodes, such as Haemonchus contortus were chosen for the project since these para...
