COCKROACHES (Periplaneta americana ): RESERVOIRS OF METALLO Β LACTAMASE AND EXTENDED SPECTRUM Β-LACTAMASE PRODUCING BACTERIA IN MEDICAL CITY HOSPITAL IN BAGHDAD, IRAQ

Abstract

Cockroaches are usually major carriers of pathogenic bacteria, prompting economic and serious health risk problem for humans by carrying bacteria and allergens. This study focuses on isolation of bacteria from Periplaneta americana in Medical City Hospital in Baghdad. In total, thirty adult cockroaches were collected randomly in February 2017. Antibiotic susceptibility test was done for each bacterial species. In total, 21 bacterial isolates were identified. The most common diagnostic bacterium isolated from the cockroaches was found to be Klebsiella pneumoniae (33.33%). Coagulase -ve Staphylococci were found in 19% of the isolates. About 42.8% of cockroach bacterial isolates were found to express ESβLs trait while 19% of isolates expressed MβLs trait. Two isolates harbored the blaTEM ESβLs gene. None of the isolates harbored blaIMP, blaCTX or blaVIM. Current study indicates that Periplaneta americana is reservoirs for bacterial isolates which produce ESβLs and MβLs.
