Urinary tract infections (UTIs) caused by resistant Klebsiella pneumoniae can lead to severe clinical complications and even death. An alternative treatment option for infected patients is using bacteriophages. In the present study, we isolated phage VB_KPM_KP1LMA (KP1LMA) from sewage water a K. strain as host. Whole-genome analysis indicated that genome was double-stranded linear 176,096-bp long DNA molecule with 41.8% GC content did not contain virulence or antibiotic resistance genes. The inactivation potential of KP1LMA assessed in broth at an MOI 1 10, maximum 4.9 5.4 log CFU/mL, respectively, observed after 9 h. efficacy 10 also urine evaluate phage’s performance acidic environment. A 3.8 CFU/mL results suggest could potentially control UTI this pneumoniae, indicating same procedure be used UTIs other strains if new specific phages are isolated. Although has narrow host range, future, efforts made expand its spectrum activity combine others, enabling use against involved UTIs.

Viruses, the majority of which are uncultivated, among most abundant biological entities on Earth. From altering microbial physiology to driving community dynamics, viruses fundamental members microbiomes. While number studies leveraging viral metagenomics (viromics) for studying uncultivated is growing, standards viromics research lacking. Viromics can utilize computational discovery from total metagenomes all (hereafter metagenomes) or use physical separation virus-specific fractions viromes). However, differences in recovery and interpretation viromes obtained same samples remain understudied.
