Three different areas – hospital, food-handling establishments and
human dwellings, were surveyed for pathogenic gram-negative
bacteria carried on cuticles of cockroaches. Fifty species of
bacteria were identified from all cockroaches. Escherichia coli,
Klebsiella pneumoniae, Citrobacter freundii and
Enterobacter Cloacae were the most frequently found. Pathogenic
and potentially pathogenic bacteria represented 58% of all bacteria
identified. The numbers of pathogenic and potentially pathogenic
bacteria were similar in hospital areas and food-handling
establishments, while human dwellings possessed a poorer bacterial
flora. E. coli, K. pneumoniae and E. Cloacae
were dominant species in hospital areas, while in food-handling
establishments and human dwellings, E. coli, K. pneumoniae
and C. freundii predominated. Therefore, cockroaches can
play a role in bacterial transmission, due to the bacterial carried
on their cuticles.
