Diagnosis Of Nasal Myiasis In The West African Dwarf (WAD) Sheep At Umudike, Abia State, South-Eastern Nigeri

OO Ikpeze

Abstract


A West African Dwarf (WAD) sheep with typical symptoms of nasal myiasis was procured on 9th December, 2008 by the Department of Microbiology and Parasitology at the College of Veterinary Medicine (CVM), Michael Okpara University of Agriculture Umudike (MOUAU) in Abia State, south-eastern Nigeria for the purpose of teaching the subject, ‘nasal myiasis’, to para-clinical students ofveterinary entomology. A sagittal secton of the head of the suspected sheep was carried out for post mortem examination, whereupon two mature maggots, identified as the third stage larvae of the sheep nostril fly Oestrus ovis, were observed in the ventral meatus. The preserved specimens will help to expand the students’ knowledge of the key identfication features of the larva of Oestrus ovis, as well as the relative positions of the anatomical organs thatmay be affected by thedeveloping larvae leadingto pathological conditions which manifest as clinica symptoms of nasal myiasis in the sheep.
