Abstract

Large vitamin A supplements, 60 μg per 1b of body wt. daily, had a beneficial effect on the course of experimental lungworm infection in calves, as shown by reduced respiratory rate, better weight gain and food utilization, a greater eosinophilic response to infection, less lung damage and a better ...

Abstract

P.M. examination of 9, 766 pairs of lungs from young and adult animals over a period of two years showed that 3% were infected with D. vivíparus There was a higher incidence of infection in younger (4%) than in older animals (1%). The disease showed a marked seasonally, autumn being the time of...

Abstract

In Ontario and Quebec, it was shown that D. viviparus larvae can both overwinter on pasture and remain dormant in the host animal throughout the winter months. Carrier animals appeared to be the more important source of infection. Preventive measures were suggested, -MGG.

Abstract

Using the flotation technique, McMaster egg counts and fecal culture of infective larvae, 1473 animals selected from various locations of the province of Quebec were studied. Fifty percent of the adults, 62% of the yearlings and 64.6% of the calves were positive by the flotation technique, but only ...

Abstract

The efficacy of cambendazole was tested in Canada against Dictyocaulus viviparus in experimentally infected calves, and in calves naturally infected with D. viviparus and gastro-intestinal nematodes. 35 mg or more of cambendazole kg body-weight was over 80% effective against mature D. viviparus....

Abstract

Transmission of the strongylid nematodes of domestic ruminants involves the interaction of a number of factors. First are those factors in the initial host, which influence the biological processes of the parasite involved in the production of infective stages. Secondly, since transmission involves ...

Abstract

In a group of "permanent", initially worm-free calves grazed continuously from the end of May to the end of November, 1974 on a pasture in Canada contaminated with Dictyocaulus viviparus larvae, the levels of faecal larval production and the size of the lungworm burdens were found, by periodic...

Abstract

Calves naturally or experimentally infected with Dictyocaulus viviparus were held under parasite-free conditions for at least 4 weeks after which the worms were recovered and studied morphologically. About 80% of inhibited larvae were in the early 5th-stage and the rest were in late 4th stage. They ...
