Abstract: (5844 Views) |
Background: Hospital infection is usually taken into consideration as a serious public health problem. A set of factors might give rise to the occurrence of these infections, including the presence of insects as the carriers of multidrug-resistant bacterial species. The present study, then, aimed to evaluate the contamination of cockroaches’ methicillin-resistant Staphylococcus aureus (MRSA) and its susceptibility pattern.
Materials and methods: In this descriptive study, over 100 cockroaches were collected and the bacterial culture of the outer and inner body was performed. MRSA was confirmed on the basis of standard methods and PCR (polymerase chain reaction). Disk diffusion method was also used to specify resistance patterns according to CLSI (Clinical and Laboratory Standards Institute) guidelines.
Results: Of 100 samples, 44 (44%) sample were contaminated to S. aureus, and also 8 (18.18%) sample of 44 samples to MRSA. The overall resistance of isolated MRSA strains to antimicrobial agents turned out to be 8 (100%) for methicillin, 7 (87.5%) for cefixime and 6 (75%) for vancomycin.
Conclusion: Cockroaches can transmit potential pathogenic bacteria therefore their presence in hospitals should be regarded as a sanitation challenge. Then, it is recommended to arrange plans to fight these pests in hospitals.
