Functional investigation of a QTL affecting resistance to Haemonchus contortus in sheep
This study reports a functional characterization of a limited segment (QTL) of sheep chromosome 12 associated with resistance to the abomasal nematode Haemonchus contortus. The first objective was to validate the identified QTL through the comparison of genetically susceptible (N) and resistant (R) sheep produced from Martinik × Romane back-cross sheep. The R and N genotype groups were then exp...
متن کاملHaemonchus contortus Acetylcholine Receptors of the DEG-3 Subfamily and Their Role in Sensitivity to Monepantel
Gastro-intestinal nematodes in ruminants, especially Haemonchus contortus, are a global threat to sheep and cattle farming. The emergence of drug resistance, and even multi-drug resistance to the currently available classes of broad spectrum anthelmintics, further stresses the need for new drugs active against gastro-intestinal nematodes. A novel chemical class of synthetic anthelmintics, the A...
متن کاملMonepantel allosterically activates DEG-3/DES-2 channels of the gastrointestinal nematode Haemonchus contortus.
Monepantel is the first drug of a new family of anthelmintics, the amino acetonitrile derivatives (AAD), presently used to treat ruminants infected with gastrointestinal nematodes such as Haemonchus contortus. Monepantel shows an excellent tolerability in mammals and is active against multidrug-resistant parasites, indicating that its molecular target is absent or inaccessible in the host and i...
متن کاملAn In Vitro Test for Drug Resistance in Haemonchus contortus
A cambendazole-resistant (CR) strain of Haemonchus contortus, the large stomach nematode of sheep, had similar in vitro growth characteristics compared to the parent strain (BPL). When the in vitro cultivation system was modified to detect drug resistance: (1) exsheathed infective larvae of the BPL strain did not develop in a culture medium with a concentration of 2.5 /ug/rnl thiabendazole (TBZ...
