Abstract

Background: The ability of infective larvae of cattle gastrointestinal nematode (GIN) species to overwinter on pastures in northerly climatic zones with very cold dry winters is poorly understood. This is an important knowledge gap with critical implications for parasite risk assessment and...

Abstract

In Australia, Cooperia spp. are often overshadowed by parasites believed to be more pathogenic production-limiting nematodes. A rise in anthelmintic resistance and reports of reduced growth rates attributed to infection with Cooperia spp. in Europe increases the need to be able to monitor the...

Abstract

Gastrointestinal (GI) nematodes are the most common nematodes in cattle; they occur worldwide and especially in temperate countries. Cooperia oncophora and Ostertagia ostertagi are the most common species which colonise the small intestines and abomasum of cattle respectively. In the last decades...

Abstract

Background: Increasing anthelmintic-resistance in nematodes of ruminants emphasises the need for sustainable parasite control. Condensed tannin-containing legume forages such as sainfoin (Onobrychis viciifolia) have shown promising anthelmintic properties in small ruminants but this has never been...

Abstract

A multiplex PCR-based method was developed to overcome the limitations of microscopic examination as a means of identifying individual infective larvae from the wide range of strongylid parasite species commonly encountered in sheep in mixed sheep-cattle grazing situations in New Zealand. The...

Abstract

Resistance against macrocyclic lactones such as ivermectin is widespread among parasitic gastrointestinal nematodes of small ruminants and is rapidly increasing in cattle parasites. ABC transporters of the subfamily B, the so-called P-glycoproteins (Pgps) have been frequently implicated in...

Abstract

The efficacy of eprinomectin in an extended-release injection (ERI) formulation was evaluated against infections with third-stage larvae or eggs of gastrointestinal and pulmonary nematodes in cattle under 120-day natural challenge conditions in a series of five studies conducted in the USA (three...

Abstract

Infections of the gastrointestinal tract with parasitic nematodes in livestock animals lead to significant impact in animal health and welfare and to enormous economic damage. The therapeutic agents commonly used for the control of gastrointestinal (GI) parasites can be divided into three main...

Abstract

Three studies were performed to test the efficacy of an ivermectin/closantel injection (200 µg/kg-1 ivermectin and 5 mg/kg-1 closantel) in cattle. Two were experimentally induced infections of Ostertagia ostertagi, Cooperia oncophora and Fasciola hepatica in calves, and the third had natural field...
