Abstract: Aims:Klebsiella pneumoniae is considered to be one of the most frequent bacterial species associated with urinary tract infections (UTIs) and recurrent UTIs (RUTIs) worldwide. The present study aimed to comprehensively characterize K. pneumoniae isolates from women suffering from UTI and RUTIs.
Methodology and results:A total of 15 clinical isolates, collected from different hospitals in Bangladesh, were tested for biochemical features, and amplified by PCR. Antibiogram assay was performed by disk-diffusion assay. Phylogenetic and functional features were analyzed using bioinformatics platform. XLSTAT was used for principal component analysis (PCA). PCR amplification using Klebsiella hemolysin gene (khe) confirmed the presence of K. pneumoniae in agarose gel with expected product size of 486 kb. Antibiogram assay revealed all K. pneumoniae isolates to be completely resistant to six out of ten relevant drugs namely ampicillin, cephradine, chloramphenicol, erythromycin, kanamycin and sulfamethoxazole used for treating UTIs in Bangladesh. Sequencing of 16S rRNA gene of clinically significant K. pneumoniae isolates showed a high level of sequence divergence among the isolates from UTI and RUTIs as well as functional features such as SNP variants and restriction sites.
Conclusion, significance and impact of study:We surmise that the results could be used as a pipeline for further research in the identification of K. pneumoniae associated with UTI and RUTIs, and treatment of infection.
