Cross-sectional prevalence of gastrointestinal helminth parasites in cattle in Lira District, Uganda.

Abstract

The prevalence of gastrointestinal helminth parasite infections and associated risk factors was studied in traditionally reared East African short-horned zebu cattle in Lira District, Uganda. Fecal samples were collected from 205 cattle and coprologically examined for the presence of helminth parasites using the simple salt flotation method complemented with the sedimentation method. The overall prevalence of gastrointestinal helminth parasites (GITPs) in cattle in Adekokwok, Lira District, was 32.2%. Of these, 12 (18.18%) were cases of mixed infections mainly of Amphistomes and other GITPs. Paramphistomum was the most prevalent parasite contributing up to 45.5% of infections, followed by Fasciola, Toxocara, strongyles, Trichuris, and Nematodirus, in descending order of abundance. GITP infections were not influenced by the sex of cattle, while infection with Toxocara was associated with cattle age. The mean body condition score (BCS) for all animals studied was 2.37 ± 0.07. A low BCS was associated with gastrointestinal helminth infections. Nevertheless, other factors such as nutritional stress are likely to augment the effects of parasites in the traditional agro-pastoral system particularly in the dry season and should therefore be considered when using the cattle body condition as an indicator of parasitism.
