Abstract

Klebsiella pneumonia is a serious pathogen involved in a range of infections. The increasing frequency of infection associated with K. pneumoniae and accelerated development of antimicrobial resistance has limited the available options of antibiotics for the treatment of infection. Bacteriophages are an attractive substitute to alleviate the problem of antibiotic resistance. In this study, isolation, microbiological and genomic characterization of bacteriophage Kp109 having the ability to infect K. pneumoniae has been shown. Phage Kp109 showed good killing efficiency and tolerance to a broad range of temperatures (4–60 °C) and pH (3–9). Transmission electron microscopy and genomic analysis indicated that phage Kp109 belongs to the genus Webervirus and family Drexlerviridae. Genomic analysis showed that the Kp109 has a 51,630 bp long double-stranded DNA genome with a GC content of 51.64%. The absence of known lysogenic, virulence, and antibiotic-resistant genes (ARGs) in its genome makes phage Kp109 safer to be used as a biocontrol agent for different purposes including phage therapy. The computational analysis of the putative endolysin gene revealed a binding energy of − 6.23 kcal/mol between LysKp109 and ligand NAM-NAG showing its potential to be used as an enzybiotic. However, future research is required for experimental validation of the in silico work to further corroborate the results obtained in the present study. Overall, phenotypic, genomic, and computational characterization performed in the present study showed that phages Kp109 and LysKp109 are promising candidates for future in vivo studies and could potentially be used for controlling K. pneumoniae infection.
