Ovine Lungworms: Ocurrence, Pathology and Associated Risk Factors in Sheep Slaughtered in Bahir Dar, Ethiopia
Journal Title: Journal of Veterinary Advances - Year 2014, Vol 4, Issue 5
Abstract
A cross-sectional study was conducted on ovine lungworms from November, 2010 to April, 2011 slaughtered in the municipal abattoir and private Hotels in Bahir Dar. The objectives of the study were to appreciate lesions, to determine the prevalence of lungworms infection, to identify the species of lungworms and to describe risk factors. Breeds of sheep under study were Farta and Washera. Gross lesions were determined by postmortem examinations and microscopic lesions were appreciated after hematoxylin eosin stain. The prevalence of lungworms was determined again using postmortem examination of adult parasites found in the lungs. The species of lungworms were identified after microscopic examination. Grossly, the most important lesions were foamy and bloody stained exudates mixed with adult parasites, multifocal patches, firm consistency of lung were detected. Histopathologically, diffused broncho and interstitial pneumonia, alveolitis, and desquamation have frequently detected. Eosinophilic inflammatory cell infiltrations around trapped adult parasites, larvae and eggs were also common. Species of lung worms identified were Dictyocaulus filaria (49.21%), Muellerius capillaris (2.34%) and Protostrongylus rufescens (1.56%). The overall prevalence was found to be 57.55 % (221/384). In all age groups, D. filaria had the highest prevalence than the other lungworms. The prevalence in Washera and Farta breeds’ was 62.5% and 57.22% respectively. In conclusion ovine lungworms were prevalent in sheep originated from Adet, Fogera, Estie, Bahir Dar and Merawi and caused significant damage on the lung and produces characteristic gross and microscopic lesions.
