Abstract

Experimental infections of Dictyocaulus viviparus were established in ten 2- to 4-month-old Holstein-Friesian calves, using a single oral dose of 5000 larvae per animal, to determine the effect of subclinical infections on health. Daily faecal samples were collected from each calf to assess the...

Abstract

Immunofluorescence on live Dictyocaulus viviparus revealed a significant antibody response by vaccinated and patently infected bovine hosts to the sheath of infective larvae (L3), a structure which is generally thought to be shed from the parasite surface prior to invasion of host tissue. In...

Abstract

Protection against challenge with D. viviparus was studied in 2 groups of calves. The cattle were immunized orally or subcutaneously (recommended route) with an irradiation-attenuated larval vaccine containing 1000 L3 on 2 occasions, 28 days apart. Compared with non-immunized controls, the...

Abstract

In a series of 5 laboratory experiments, observations were made on the role of Pilobolus in the translation of infective D. viviparus larvae from faeces of cattle. The results indicated that a substantial proportion of the lungworm larvae present in the faeces may be translated from the faeces by...

Abstract

Inactivation of selected bovine parasites was measured quantitatively during anaerobic digestion of bovine slurry in small-scale batch digesters. Mesophilic (35°C) and thermophilic (53°C) anaerobic digestion accelerated the inactivation of parasitic nematodes, compared to survival under...

Abstract

In investigations carried out on pasture it was noted that large numbers of infective larvae of D. viviparus appeared after soil disturbance. The authors suggest that this might be due to the presence of a "soil reservoir".

Abstract

Fenbendazole at 1.3 mg/ml was larvicidal within 40-60 minutes when added to cultures of larval nematodes. Higher concentrations, up to 2 mg/ml, acted more rapidly and effectively. In cattle and young sheep, fenbendazole rapidly reduced faecal egg counts for Ostertagia, Dictyocaulus, Strongyloides ...

Abstract

Seasonal variations in contamination of pastures with Dictyocaulus larvae were studied on winter (plain) and summer (alpine) pastures and on cattle tracks. On winter pastures maximal contamination was observed in spring (before transhumance) and autumn (after return from alpine pastures);...
