Gastrointestinal parasites are ubiquitous. They occur both in wild and domesticated animals. Among such of veterinary importance is the trichostrongyle worms, out which Haemonchus contortus species regarded as most pathogenic one small ruminant industry. The occurrence this parasite sheep flock now very well documented an established fact Europe, although was original warmer climatic region. St...

The study of electrophoretic pattern of Haemonchus contortus has proved to be an important tool for vaccine designing. The aim behind the review is to encourage young researchers to initiate work on this aspect. Disease biomarker discovery is generally carried out using two dimensional polyacrylamide gel Electrophoresis (2D-PAGE) to identify differences in the protein expression patterns. After...

A group of 12 Merino lambs, 3,5 months of age, which were still suckling, were each dosed with 40 000 infective larvae of Trichostrongylus axei on Day 0. From Day +62-Day 64 each of these lambs and those of a 2nd group of 11 controls were dosed with 30 000 infective larvae of Haemonchus contortus, and all the lambs of both groups were killed on Day +90. Attempts to use T. axei to protect them a...

background: accurate identification of sheep nematodes is a critical point in epidemiological studies and monitoring of drug resistance in flocks. however, due to a close morphological similarity between the eggs and larval stages of many of these nematodes,such identification is not a trivial task. there are a number of studies showing that molecular targets in ribosomal dna (internal transcri...

On the strength of a complaint of suspected resistance to closantel, a field strain of Haemonchus contortus was isolated from sheep on a farm near Pretoria and tested for resistance to the remedy, both without exposure to closantel in the laboratory (designated the "unselected" substrain of the parasite) and after a single selection with closantel (called the "selected" substrain). For comparat...

AIM Gastrointestinal helminthosis is a global problem in small ruminant production. Most parasites have developed resistance to commonly available anthelminthic compounds, and there is currently an increasing need for new compounds with more efficacies. This study evaluated the in vitro effects of ethanolic extract of Curcuma longa (EECL) as a biological nematicide against third stage Haemonchu...

Nutraceuticals are defined as livestock feeds that combine their nutritional value with beneficial effects on animal health. We analyzed the outcomes from nearly 20 years of research assessing nutraceutical properties plants consumed by sheep and goats in low deciduous forests. A systematic review different databases suggested 31 peer-reviewed manuscripts according to pre-established criteria. ...
