Abstract

 

This descriptive study was carried out to determine bacterial infection rate of cockroaches in the residential dwellings. A total of 650 cockroaches were collected in Sanandaj city houses using sticky traps, direct collection and vacuum cleaner. After determination, 85 of them were examined in base standard methods for bacterial infection. Two species of cockroaches including Blattela germanica (54%) and Periplaneta americana (46%) were collected. 74% of cockroaches had bacterial infection and separated into seven groups including: PseudomonasEnterobacter, Escherichia, non pathogens staphylococci,KlebsiellaProteus and SeratiaEscherichia coli had the most frequency (61.5%) andSeratia (6.1%) had the least.
