Lungworm Infections in Sheep Slaughtered in Tiaret Abattoir (Algeria)

3 Abstract: The aim of this study was to estimated the prevalence and identification of species of lungworm infection in sheep slaughtered in Tiaret abattoir from December 2011 to November 2012. Post mortem examination was conducted on 1433 animals and laboratory work was done on 100 rejected lungs for lungworm infections to identifying parasite species. Results: 318 sheep were found to be positive for lungworm infections with an overall prevalence of 22%. There was a higher statistically significant difference (P=0.0000) observed between female and male animals with prevalence of 27% and 12%, respectively. The older animals were more affected, than the younger's ones (P=0.0000). The prevalence of species of lungworm identified were Muellerius cappilaris (40%), Protostrongylus rufescens (27%), Dictyocaulus filaria (28%) and 5% of mixed infections. This study showed high prevalence of lungworm infections in the study area implying the need for control intervention.
