20 American cockroaches were collected and identified in this research. All of these insects examined in this study. A total of 18 cockroaches (90%) were infected with at least one bacterium and 2 cockroaches (10%) were not infected. A broad spectrum of bacteria, such as, Klebsiella spp. (35%), Pseudomonas spp. (30%), E. coli (15%), Staphylococcus spp. (10%), Proteus spp. (5%) and Streptococcus spp. (5%) were isolated. Klebsiella spp. was the most widespread bacteria recovered on cockroaches. Proteus spp. and Streptococcus spp. had the least prevalent bacteria recovered on their external surface.
