Isolation of potentially pathogenic bacteria from public service cars door handles

Abstract

The possible bacterial contamination of the door handles of public “service” cars working within the city of Beirut, the capital of Lebanon, was investigated. Door handles from 22 cars were sampled and cultured on multiple culture media. From the 22 samples, 29 different isolates were grown and identified. Of these, 17 (58.6%) were Staphylococcus aureus, 11 (37.9%) were coagulase-negative Staphylococcus spp. and 1 (3.5%) was Klebsiella oxytoca. Of the 22 door handles sampled, 16 (72.7%) grew Staphylococcus aureus, 12 (54.5) grew coagulase-negative Staphylococcus spp., 1 (4.5%) grew Klebsiella oxytoca and 2 (9.0%) did not grow any organism. As the isolated organisms were involved in nosocomial and community acquired infections, their presence poses a threat, especially to passengers who might be immunocompromised. Regular cleaning procedures are suggested to protect the users of these door handles from the possible dangers associated with these organisms.
