Abstract

Outbred Dunkin-Hartley and inbred strain 2 and strain 13 guineapigs were immunized with Dictyocaulus viviparus adult ES products prior to challenge with 3rd-stage larvae. Antibody responses of the 3 strains to adult ES products and the acetylcholinesterase (AChE) isoforms which they contain were...

Abstract

The effect of annually alternating cattle and sheep was investigated in UK as an alternative to drug therapy in the control of bovine helminth infections. Until the second grazing season this system appeared to be successful, with a marked reduction in cattle worm burdens. However, by the end of...

Abstract

Parasite preparations were examined for their ability to induce protective immunity against Dictyocaulus viviparus in guineapigs. Dunkin-Hartley strain guineapigs were immunized with somatic extracts of adult parasites, somatic extracts of third stage larvae or excretory/secretory (ES) products...

Abstract

Monoclonal antibodies (MAbs) to the Dictyocaulus viviparus L3 cuticle and sheath surfaces were generated in order to define antigens present at the host-parasite interface of infective larvae. Three MAbs generated against the surface of the infective L3 cuticle bound to a phosphorylcholine-like...

Abstract

The adult ES products of Dictyocaulus viviparus are a source of protective antigens against challenge in the guineapig laboratory model. High levels of acetylcholinesterase (AChE) activity are present in these products and these enzymes are immunogenic in infected cattle. The potential role of...

Abstract

MAb 2A6 bound to the surface of the Dictyocaulus viviparus L3 sheath and identified a molecule which is highly antigenic in both infected and vaccinated cattle. Immunogold electron microscopy revealed that the antibody binds to a highly stable surface coat overlying the epicuticle of the L3 sheath. ...

Abstract

Antibody responses to the surface-exposed antigens of living Dictyocaulus viviparus larvae and adult worms were measured by quantitative immunofluorescence using sera from calves infected with, or vaccinated against, the parasite. In infected animals, the sheath surface of third-stage (L3), which...

Abstract

In order to establish the infection pattern with gastrointestinal nematodes in ruminants in the central Kenya highlands, a study was carried out in 58 smallholder farms between March 1995 and October 1996. The study involved monthly faecal examinations from sheep, goats and cattle and pasture...
