Anthelmintics for Dictyocaulus filaria in Sheep

Vascular permeability increasing action of the saline extract of Dictyocaulus filaria--a preliminary report.

The cutaneous hypersensitivity reaction in sheep infected with Dictyocaulus filaria was investigated. The saline extract of the worms increased the cutaneous capillary permeability in both the infected and uninfected control animals. Similar increase in the permeability was also observed in uninfected healthy rabbits. The results suggest that the vascular permeability increasing action of the w...

Bile enhances the infectivity of third stage larvae of Dictyocaulus filaria.

TITOY, G.A.P. & SCHWAN, E.V. 1994. Bile enhances the infectivity of third stage larvae of Dictyocaulus filaria. Onderstepoort Journal of Veterinary Research, 61:395-396 Incubating metacyclic larvae of Dictyocaulus filaria in ovine bile solution prior to per os infection significantly enhanced their infectivity to sheep. INTRODUCTION Although there are several reports on the effect of bile on th...

Analysis of the transcriptome of adult Dictyocaulus filaria and comparison with Dictyocaulus viviparus, with a focus on molecules involved in host-parasite interactions.

Parasitic nematodes cause diseases of major economic importance in animals. Key representatives are species of Dictyocaulus (=lungworms), which cause bronchitis (=dictyocaulosis, commonly known as "husk") and have a major adverse impact on the health of livestock. In spite of their economic importance, very little is known about the immunomolecular biology of these parasites. Here, we conducted...

Studies on Dictyocaulus filaria. I. Modifications of laboratory procedures.

ANDERSON, P. J. S. and VERSTER, ANNA, 1971. Studies on Dictyocaulus filaria. I. Modifications of laboratory procedures. Onderstepoort]. vet. Res. 38 (3), 181-184 (1971). Techniques used in a study of the life-cycle of Dictyocaulus filaria (Rudolphi, 1809) are described. First stage larvae migrate from faecal pellets placed in water. Infective larvae are cultured in clean water at room temperatu...
