              Abstract 
 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.
