Aim: A detailed post mortem examination was 
                              conducted on the animal to know the cause of the 
                              death. Materials and Methods: Detailed 
                              post-mortem examination was carried out. The 
                              Impression smears from the affected organs was 
                              taken and subjected to Gram's staining technique 
                              for preliminary identification of the 
                              micro-organism. The suspected tissues were 
                              processed for histological investigation by 
                              formalin fixation and paraffin embedding technique 
                              as explained by Luna. 
                              
                              
                              Results: Hardware 
                              diseases in cattle are a common feature in 
                              developing countries where organized farming is 
                              still not an adopted practice of management. 
                              During post mortem examination, a case of foreign 
                              body penetration induced splenitis was 
                              encountered. A large irregular abscess cavity was 
                              found with greenish liquefactive material found 
                              wherever the foreign body had penetrated. Multiple 
                              focal abscesses were found in the parenchyma along 
                              with congestion and edema. The histopathological 
                              investigation revealed inflammation with 
                              neutrophilic liquefactive debris, mild fibrosis, 
                              vascular sclerosis, focal lymphocytolysis and 
                              numerous chains of regular sized bacilli in the 
                              parenchyma, determined to be Bacillus spp. Trauma 
                              due to foreign body is rare in spleen due to its 
                              anatomical location. 
                              
                              
                              Conclusion: Foreign 
                              body penetration induced splenitis was 
                              encountered. The histopathological investigation 
                              revealed inflammation with neutrophilic 
                              liquefactive debris, mild fibrosis, vascular 
                              sclerosis, focal lymphocytolysis and numerous 
                              chains of regular sized bacilli in the parenchyma, 
                              determined to be Bacillus spp. Keywords:
