Dictyocaulus viviparus: The role of pepsin in the exsheathment of infective larvae

Experimental Parasitology, 1976
Abstract Following the report of Silverman and Podger (1964) that pepsin formed an association with larval receptor sites on D. viviparus and that exsheathment had an absolute requirement for pepsin, the role of pepsin was studied in greater detail. A range of enzyme incubation, pepsin labeling, histochemical and electron microscopical techniques

Effect of dictyocaulus filaria infection on the osmotic fragility of sheep erythrocytes

Veterinary Parasitology, 1989
The osmotic fragility of erythrocytes in lambs experimentally infected with Dictyocaulus filaria was studied weekly for 71 weeks. In acute infection, the erythrocytic fragility increased from the third week of infection onwards, reached its peak by the eleventh week and declined thereafter. However, in the chronic immune-carrier stage, this increase in

Energy and Nitrogen Metabolism of Growing Calves Continuously Infected with Dictyocaulus Viviparus

1987
The influence of a moderate level of continuous lungworm infections on energy and nitrogen metabolism of calves was investigated. A pair-feeding and a pair-growing experiment were performed. The metabolism parameters were related to clinical, parasitological, haematological and serological parameters.

The effects of Dictyocaulus viviparus infection on energy metabolism of calves.

Journal of animal science, 1989
To determine the effects of lungworm infection on energy metabolism and rate of weight gain, five 3-mo-old male Friesian calves were infected orally twice each week with 640, third-stage larvae of Dictyocaulus viviparus (D.v.) over an 8-wk period. Infected calves were matched with uninfected controls on the basis of similar rates of feed consumption ...

Monitoring Pasture Infectivity and Pasture Contamination with Infective Stages of Dictyocaulus viviparus

1981
The technique for the estimation of pasture larval contamination by the examination of herbage is presented. Samples are taken near to faecal pats where the larvae are expected to be concentrated; a second sample taken at least 100 cm from the faecal pat provides information on the horizontal distribution of the pasture contamination.

[Fluorescent microscopy in the diagnosis of Dictyocaulus infection in sheep].

Veterinarno-meditsinski nauki, 1976
Fluorescence microscopy was employed to study Dictyocaulus infection in 15 experimentally infected lambs each given 2000 D. filaria larvae. Studied were also the sera of 10 control lambs and of 20 sheep and goats infected with other helminths. Antibodies were established after the 14th day in 53 per cent of the lambs, the 20th day in 86.6 per cent, and
