Overview of anthelmintic resistance of gastrointestinal nematodes of small ruminants in Brazil

Overview of anthelmintic resistance of gastrointestinal nematodes of small ruminants in Brazil.

Frequent and inappropriate use of all classes of antiparasitic drugs in small ruminants has led to failures in their effectiveness, culminating in a global problem of anthelmintic resistance. Brazil stands out as one of the world's leaders in publications about anthelmintic resistance, and for having the most numerous reports of this resistance in small ruminants in the Americas. These studies ...

Anthelmintic Resistance and Management of Gastrointestinal Parasites in Small Ruminants: an Update

INTRODUCTION The problem of anthelmintic resistance in gastrointestinal nematodes (GIN) of small ruminants is world wide in distribution. In the past 20 years no new classes of anthelmintics have been developed for use in animals. Anthelmintic resistance has been documented to all classes of anthelmntics and multi-class resistance exists in many flocks. The challenge to veterinarians and produc...

Anthelmintic resistance in ovine gastrointestinal nematodes in inland southern Queensland.

OBJECTIVE To establish the prevalence of anthelmintic resistance in ovine gastrointestinal nematodes in southern Queensland. DESIGN An observational parasitological study using the faecal egg count reduction test. METHODS Sheep farms (n = 20) enrolled in this study met the twin criteria of using worm testing for drench decisions and having concerns about anthelmintic efficacy. On each farm,...
