Parasitic encephalitis caused by larvae of Oestrus ovis in Sirohi goat

Oestrosis is a nasal myiasis of sheep and goats caused by the larvae of fly Oestrus ovis. An adult male Sirohi goat died with the history of muco-purulent nasal discharge, laboured breathing, depression and head pressing. The post-mortem examination revealed aberrant, unilateral encephalitis characterized by severe necrosis of entire left cerebral hemisphere. Infestation and recovery of the nasal bots of goats from the aberrant sites like cranial cavity and brain is unusual and rare.
