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...

A group of Merino sheep, aged 67 months was infested orally with 50 000 infective larvae of Trichostrongylus axei. This group and a control group were challenged 9092 days later with 50 000 infective...
متن کاملImmune cell kinetics in the ovine abomasal mucosa following hyperimmunization and challenge with Haemonchus contortus
Sheep were sensitized by repeated infection with Haemonchus contortus L3, followed by a 12 week rest period, and an abomasal cannula was surgically implanted in all sheep. Seven of the sensitized sheep were subsequently challenged with 50 000 H. contortus L3 while 4 control sheep were challenged with saline. Biopsy samples were taken using a fibreoptic endoscope on days 0, 1, 2, 3, 5, 7 and 28 ...
متن کاملTwo field strains of Haemonchus contortus resistant to rafoxanide.
Two field strains of Haemonchus contortus, one from Pretoria on the Highveld and the other from White River in the Lowveld of the Transvaal, showed pronounced resistance to rafoxanide at a dosage rate of 7.5 mg/kg live mass per os. Both of these strains originated from kikuyu pastures under irrigation. Resistance in South Africa to rafoxanide and other anthelmintics, namely, closantel, ivermect...
