Lekooporność nicieni żołądkowo-jelitowych kóz. Część I. Epidemiologia, przebieg kliniczny i rozpoznawanie inwazji

This article presents the major genera and species of gastrointestinal nematodes found in goats, along with appropriate diagnostic methods. Many health problems in goat herds are related to the infection gastrointestinal nematodes. In Poland, the most common goat nematodes belong to the species H. contortus and to genera Trichostrongylus and Teladorsagia. The clinical signs of infection are non-specific and include diarrhoea, pale mucous membranes, oedema of soft tissues, and weight loss. Diagnosis is based on qualitative (simple flotation), and quantitative (McMaster’s method), and larvoscopic methods (Baermann’s method). Differentiation of the species and genus of gastrointestinal nematodes is carried out using invasive larvae culture methods and molecular biology (PCR) methods.
