Immunological responses of sheep to Haemonchus contortus.
Infections with Haemonchus contortus are a major constraint on ruminant health world-wide. Young lambs are very sensitive to Haemonchus infection. Older lambs and sheep acquire immunity after a continuous or seasonal exposure to the parasite. The mechanisms underlying immunity are still not completely understood. Antibodies, in particular local IgA and IgE, certainly play a role. The role of Ig...
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...
متن کاملSelection for anthelmintic resistance by macrocyclic lactones in Haemonchus contortus.
Two morphologically marked strains of Haemonchus contortus, CAVRS (smooth-macrocyclic lactone resistant) and McMaster (linguiform-macrocyclic lactone susceptible), were used to investigate the selection for anthelmintic resistance following exposure to ivermectin (IVM), a non-persistent anthelmintic. and a more persistent anthelmintic, oral moxidectin (MOX). Three types of selection were invest...

متن کاملHaemonchus placei and Haemonchus contortus are distinct species based on mtDNA evidence.
Debates continue over the extent to which the parasitic trichostrongylids Haemonchus placei and Haemonchus contortus hybridise in nature, and whether they deserve species status. Mitochondrial ND4 gene sequences from individuals of each putative species collected from populations around the United States indicate that the two species are highly differentiated at the mtDNA level. Furthermore, th...
