Abstract

In this review of Dictyocaulus viviparus infection of cattle, the pathology of parasitic bronchitis is explained according to the various stages in the development of primary infections and a summary is given of the various clinical signs. The epidemiology of bovine dictyocauliasis, its diagnosis,...

Abstract

Work in Scotland which indicated that outbreaks of parasitic bronchitis (Dictyocaulus viviparus) in calves can arise from larvae which have overwintered in the soil is recapitulated [see Hm/A 48, 6091].

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

In vitro released products of the adult stage of Dictyocaulus viviparus were characterized according to their SDS-PAGE profile, glycosylation pattern, in vitro synthesis and antigenicity in the context of infection and vaccination with irradiated larvae. Biosynthetic labelling experiments with ...

Abstract

An ELISA was developed to measure accurately levels of the trypanocidal drug isometamidium in the serum of treated cattle. The assay requires only 5 µl of test serum, is sensitive to a level of 0.5 pg/ml and is highly specific. Cross reactivity does not occur with the two other widely used...

Abstract

The duration of a single isometamidium chloride (Samorin) prophylactic treatment against T. congolense ILNat 3.1 and T. congolense IL 285 was examined in 24 Boran steers. The cattle were repeatedly challenged at monthly intervals between 2 and 7 months following treatment, either by 5 infected ...

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...
