Aerobic bacteria occurring in the hind-gut of the cockroach,Blatta orientalis

Abstract

SUMMARYMethods are described for the isolation and identification of aerobic bacteria occurring naturally in the hind-gut of the cockroachBlatta orientaliscaptured from a number of wild sources, to establish whether or not human pathogens occurred naturally within the gut. During the investigation an organism was frequently found which could not be classified in any described species, and for which we propose the nameEscherichia blattae.
