Aim: The present study was undertaken to study the pathology and control of sudden unexplained mortality in wistar rats. Materials and Methods: This study was conducted in a colony of 25 male wistar rats where there was mortality of nine rats. The dead rats were subjected to thorough post-mortem examination and necropsy samples were processed for hematoxylin and eosin staining for histopathological studies. Faecal samples of live rats were studied for the presence of parasitic eggs. Treatment with anthelmintics was given to manage the mortality and infections. Results: The investigation revealed a natural co-infection of Cysticercus fasciolaris and Hymenolepis diminuta in wistar rats, which were pathogenic enough to cause mortality. Typical lesions associated with the parasites were found in the dead rats. The mortality and infection were managed with common anthelmintics. Conclusion: C. fasciolaris and H. diminuta infection can cause mortality in wistar rats even when individually they cause asymptomatic infection. The mortality and infection can be managed with common anthelmintics.
