Nosocomial infections: cockroaches as possible vectors of drug-resistant Klebsiella.
The possibility that hospital cockroaches may act as vectors of drug-resistant Klebsiella spp. was investigated during Nov 1985 to April 1989, at the All India Institute of Medical Sciences (AIIMS) hospital. Klebsiella spp. (majority Klebsiella pneumoniae) were isolated from 28.3% of hospital cockroaches and 28.1% of infected wounds of patients. Most of Klebsiella isolates from patients (96.3%), and hospital cockroaches (85.9%) showed multiple drug resistance to four or more antimicrobials. Similar strains of Klebsiella spp. were encountered among patients and hospital cockroaches. These findings suggest that hospital cockroaches may act as vectors of drug-resistant Klebsiella spp. and may contribute to the epidemiology of nosocomial infections.
