Abstract

A total of 358 cattle was examined for schistosome infection in Zambian slaughterhouses. A total of 542 worms collected from 104 infected individuals was examined for glucose-6-phosphate dehydrogenase and phosphoglucomutase using isoelectric focusing. The overall prevalence of infection was 51%....

Abstract

The problem of anthelmintic resistance has so far received little attention in Belgium mainly because of the relative unimportance of the small ruminant production in this country. However, small surveys in horses and sheep have indicated that benzimidazole resistance is relatively widespread in...

Anthelmintic resistance in nematodes of farm animals. A seminar organised for the European Commission, held in Brussels, Belgium, from 8 to 9 November, 1993., 1994, pp 41-46
Abstract

Development of immunity to Ostertagia ostertagi and Cooperia oncophora and interactions between both species in primed calves were investigated after homologous, heterologous and concurrent challenge infections. Worm counts, faecal egg output, IgG1 and IgG2 antibodies and the presence of globule...

Abstract

Cooperia oncophora total adult extracts were examined by Western blotting with sera from C. oncophora- and Ostertagia ostertagi-infected calves to determine species-specific antigens. It was shown that 2 antigens with apparent MWs of 14 200 and 14 900 were only recognized by calves which received a ...

Abstract

Antigenic differences between the developmental stages of O. ostertagi were studied by SDS-PAGE and Western blotting. Gel electrophoresis showed a complex protein pattern different for every stage with the O. ostertagi fourth stage larvae (L4) showing an intermediate protein pattern between the...

Abstract

The pathology of natural S. spindale infections in cattle in Sri Lanka was studied. Hepatic lesions were moderate with periportal cell infiltration and periportal epithelioid cell granulomas within perilobular zones. Submucosal and mucosal granulomas accompanied by cellular changes were present in...

Abstract

The Schistosoma mattheei egg output was monitored in 31 cattle over a 18-month period on a dairy farm near Lusaka, Zambia. The animals were kept on pasture with free access to two streams which were suitable for the intermediate host, Bulinus globosus. Individual faecal egg excretion reached an...

Abstract

The inverse relationship between the intensive use of modern anthelmintics and the build up of immunity to gastrointestinal nematodes in cattle is discussed. Manifestations of immunity, humoral reactions, cell-mediated reactions, control, and chemoprophylaxis and immunity are discussed. It is...

Abstract

Ostertagia ostertagi adult worm extracts were analysed by Western blotting using sera from calves experimentally infected with O. ostertagi and Cooperia oncophora. Strong differences in antigen recognition were noticed, even between animals from the same group. Two Ostertagia specific antigens with ...

Abstract

Thirty parasite-naive Holstein-cross heifers aged 7 to 12 months were allocated into 3 groups and were treated with either an oxfendazole pulse release bolus (Repidose) administered orally at turnout or ivermectin (Ivomec) injected s.c. at 200 µg/kg at 3, 8 and 13 weeks after turnout or untreated...
