Domestic cockroaches (Periplaneta americana) are reddish brown to black in colour and they resides at local areas like in the kitchens, bathrooms, dark areas, cracks of buildings, near the garbage, wet places, spoiled food materials and at many more similar places. They carry several types of microorganisms on their external surfaces as well as at their internal surfaces. Some of these microorganisms are dangerous for humans as they cause several life threatening diseases like salmonellosis, typhoid fever, cholera etc and some of them shows potential industrial applications like antimicrobial activities, antibiotic activities.Most bacteria which are associated with the cockroaches are comprised of the family Enterobacteriaceae. Most common bacterial species which are found from the cockroaches are Serretia, Pseudomonas, Klebsiella, bacillus. This study has been undertaken for isolating and identifying the bacteria from the gut and external surface of the Periplaneta americana.For isolating purposes several selective and differential media were prepared and for identification purposes gram staining and various biochemical tests were carried out.
