Background: In hospitals, it has been clarified that Periplaneta americana can operate as possible vectors of nosocomial infections, chiefly for the transmission of drug-resistant bacteria. Also, these domestic insects have a role in transmitting food-borne diseases. The bacterial loads of these insects have been reported as seven million in each excretion dropping and up to 14 million on their cuticle. Their presence decreases human health and sanitary standards. Objectives: This descriptive study was carried out to confirm that Periplaneta americana L. (Dictyoptera; Blattidae) carry pathogenic bacteria in residential areas, by bacteriological analysis of the cuticles of this insect. Results: One hundred percent of cockroaches had bacterial infections. Culturing of the external parts wash homogenates resulted in the isolation of Escherichia coli , Proteus , Serratia, Klebsiella , Enterobacter , Pseudomonas , Staphylococcus Conclusions: The results showed that P. americana is a possible reservoir and potential vector of some pathogenic agents.
