Abstract
species) group of pathogens and is responsible for nosocomial infections. The global increase of carbapenem-resistant K. pneumoniae has developed a substantial clinical threat because of the dearth of therapeutic choices available. K. pneumoniae is one of the commonly found bacteria responsible for biofilm-related infections. Due to the inherent tolerance of biofilms to antibiotics, there is a growing need to develop alternative strategies to control biofilm-associated infections. This study characterized a novel bacteriophage PG14, which can inhibit and disrupt the K. pneumoniae biofilm. The genome of phage PG14 does not show any putative genes related to antimicrobial resistance or virulence, making it a potential candidate for phage therapy. This study displays the possibility of treating infections caused by multidrug-resistant (MDR) isolates of K. pneumoniae using phage PG14 alone or combined with other therapeutic agents.
