Experimental transmission studies demonstrated that certain parasite species could cause an acute clinical disease in sheep and pigs severely affecting their health, productivity and reproductivity. Despite the high prevalence of infections found in farm animals, few outbreaks of naturally-occurring clinical disease have ever been recorded. Host animals exposed to low levels of infection were found to develop a strong protective immunity against subsequent lethal challenge and clinical disease even though parasites were not completely eliminated nor prevented from further establishment (premunitive immunity rather than sterile immunity). Modern molecular biological techniques are currently being used to examine the parasite antigens and host immune responses involved in the acquisition of the protective immunity.</p>","PeriodicalId":75492,"journal":{"name":"Angewandte Parasitologie","volume":"33 2","pages":"102-19"},"PeriodicalIF":0.0,"publicationDate":"1992-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12776732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The strong reaction of the various mitochondrial enzymes and ATPase suggests a possible respiratory role of the bacillary band in this species. The most noticeable effect of these two drugs especially the higher concentrations on the intestine was the disruption of its epithelium with the release and scattering of the enzymic activity of the various enzymes such as SDH, GDH (only fenbendazole treatment), NADPH-D and NADH-D.
