Objectives
Klebsiella pneumoniae is a gram-negative rod bacterium, a known cause of community-acquired bacterial pneumonia and is an important hospital-acquired pathogen that causes severe morbidity and mortality. The aim of this study was to identify the TEM and SHV genes in K. pneumoniae isolated from cockroaches obtained from hospitals.
Methods
In this study, 250 cockroaches were collected from different hospitals in the province of Chaharmahal Va Bakhtiari, which is located in southwest Iran. The samples were examined for the presence of K. pneumoniae by plating onto a combination of culture media, and the antimicrobial susceptibility patterns of isolated K. pneumoniae from samples were evaluated using the disk diffusion test. In addition, from the culture, genomic bacterial DNA was extracted, and sequence-specific targets (TEM and SHV genes) were amplified using the polymerase chain reaction (PCR) method.
Results
Out of 250 cockroach samples collected from various hospitals, 179 samples (71.60%) were positive for K. pneumoniae. PCR reaction was performed using specific oligonucleotide primers (TEM-F, TEM-R and SHV-F, SHV-R) for the amplification of each gene, and amplified products were visualized on 1% agarose gel electrophoresis. Of all the specimens amplified by PCR in this research, 32 samples (17.87%) were positive for TEM and 15 samples (8.37%) were positive for SHV.
Conclusion
Detection of TEM and SHV genes using molecular methods and their pattern of antimicrobial resistance can provide useful information about the epidemiology of and risk factors associated with K. pneumoniae infection.
