Interactions between gastrointestinal parasitism and pneumonia in Nigerian goats

This study was carried out to determine the burden and interactions between parasitism and pneumonia in Nigerian goats. A total of 430 goats were examined for gastrointestinal (GIT) parasites by faecal analysis using sedimentation by gravity, Modified Winconsin sugar floatation method, McMaster egg counting techniques and for lung consolidation, pathology and morphometry of pneumonia were evaluated by standard techniques. The results from the faecal examination revealed the presence of nine (9) gastrointestinal parasites namely Eimeria, Trichuris, Oesophagostomum, Strongyloides, Moniezia, Haemonchus, Bunostomum, Trichostrongylus, and Nematodirus species and at an overall high prevalence of 74%. Eimeria species was found to have the highest prevalence of 26% for single infection, while co-infection of Eimeria and Trichuris species 21% was highest amongst other parasites, and of the breeds of goats examined for GIT parasites, the Red Sokoto (RS) breed had the highest infection rate 37%. The results from the lungs analysis showed 59% prevalence with the highest consolidation in RS (48.2%), followed by WAD (34.2%). The age of the goats was key in the infection rate of both parasites and pneumonia, which was seen to be highest in younger goats, with a significant (2.10 ± 0.4 × 10³) GI parasite burden in >1–2 years group. The prevalence of GIT infection with lung consolidation in the goats, was observed to influence their Body condition scores (BCS) (p < 0.05). This study showed that body condition score, age and breed of goats may be predisposing factors to gastrointestinal parasites and pneumonia in Nigerian goats. There was a strong correlation (+0.243, p = 0.00) of occurrence of gastrointestinal parasitism and pneumonia in this study. Possibility of combined prophylactic measures should be considered in the nearest future.
