Abstract

Using a new sensitive egg count test, FLOTAC, it has been shown that macrocyclic lactones (MLs) had reduced efficacy against gastrointestinal nematodes including Cooperia species and Ostertagia ostertagi on the majority of cattle farms investigated. Product failure was also found to levamisole...

Abstract

The aim of this study was to optimize an in-house ELISA based on a recombinant version of the major sperm protein (MSP) of Dictyocaulus viviparus for routine diagnosis of lungworm infection in cattle. A recombinant MSP (rMSP) was cloned into pGEX-6P-1 vector and expressed as a...

Abstract

A study was conducted to confirm the efficacy of topical eprinomectin against nematodes and to evaluate the pharmacokinetics in cattle prevented from having physical contact with other cattle and from self-grooming. Sixteen male Brown Swiss calves were infected with larvae of recently isolated...

Abstract

Twenty-four Holando Argentino male calves were treated orally with 50 mg/kg body weight trichlorphon (TCF); 0.2 mg/kg body weight subcutaneous ivermectin (IVM); a combination of TCF+IVM at the same doses and administration routes; or remained untreated (control group). All calves were necropsied at ...

Abstract

Galectin-11 (LGALS11) has been suggested to play an important role in protective immunity against gastrointestinal nematodes in ruminants. However, in cattle, this molecule has not been characterized in detail. In the current study, it was shown that transcription of LGALS11 was highly inducible in ...

Abstract

The persistence of the effect of ivermectin and abamectin against gastrointestinal nematodes and lungworm in cattle was investigated in 2 trials, each involving 28 animals. Groups of 7 cattle either remained untreated, or were treated topically with ivermectin at 500 µg/kg bodyweight or s.c. with...

Abstract

In this study to assess the persistence of abamectin (Avomec, Duotin) as shown by its efficacy against some common nematode parasites, 14 castrated male calves which were free of parasitic nematodes were treated with abamectin (200 µg/kg s.c.; 7 calves) or acted as controls (7 calves). 14 days...

Abstract

Over a period of 1 year, from November 1997 to October 1998, the abomasa, blood and faecal samples of 121 dairy cows in Belgium were collected and examined for nematode infections. Nematodes were present in the abomasa of 110 animals. Ostertagia ostertagi was found in all 110, Trichostrongylus was...
