In this study, a cell culture of Klebsiella pneumoniae and a cocktail of 3 virulent bacteriophages were used. K. pneumoniae is associated with human diseases such as pneumonia, urogenital infection, liver abscess, bloodstream infection, etc. It is one of the most frequently detected bacteria in human respiratory tract infections, especially in hospitalized patients with pneumonia associated with treatment in intensive care units (ICU), including ventilator-associated pneumonia (VAP) [1]. Among bacterial complications after viral respiratory tract infections, including SARS-CoV-2, pneumonia associated with K. pneumoniae is also the most common [2,3]. The treatment of such complications is challenged by increasing levels of bacterial resistance to antimicrobial drugs.
A video of bacterial culture growth and the initial stages of biofilm formation was filmed during the experiment. Two and a half hours after the addition of bacteriophages to the system, active lysis of the bacterial cells began and within 30 minutes all microcolonies were disrupted.
