Simulation of Pasture Larval Populations of Haemonchus Contortus
Studies at Armidale on the ecology of helminthoses have provided information on the populations of both parasitic and free-living stages of sheep nematodes under varying seasonal conditions. The complexity of the climatic, nutritional, physiological and immunological factors which interact in the epidemiology of parasitic disease is such that even given this information, it is difficult to pred...
متن کاملImmunological 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 کاملSynergistic inhibition of Haemonchus contortus exsheathment by flavonoid monomers and condensed tannins
This study investigated the separate and combined anthelmintic (AH) effects of different phenolic compounds, including condensed tannins and flavonoids, all of which are known to occur in willow leaves, a potentially valuable dry season feed. A range of contrasting model tannins, which span the whole range of willow tannins, were isolated from tilia flowers, goat willow leaves, black currant le...
متن کاملImmunodiagnosis of Haemonchus contortus infection in sheep by indirect enzyme linked immunosorbent assay (ELISA)
Indirect plate enzyme-linked immunosorbent assay was standardized and evaluated for its effectivenessin immunodiagnosis of haemonchosis in experimental and clinical cases in sheep by using somatic wholeadult antigen of H. contortus. Plate ELISA was standardized using 5 μg/well antigen concentration with1:100 and 1:1000 of sera and conjugate dilution. Indirect plate ELISA was able to demonstrate...
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...
