The autopsy showed acute enteritis, acute peritonitis and 

 pleuritis. No histological examination was made. 



Result: The reaction of this guinea-pig is inconsistent with 

 typhus with or without a complicating infection. 



Conclusion: Rickettsia-free louse W 263 (probably?) did not 

 contain the virus of typhus.
