More Details: Abstract Klebsiella pneumoniae, a pathogen of concern worldwide can be classified as classical K. pneumoniae (cKp) and Hypervirulent K. pneumoniae (HvKp). In health care settings, genotyping and identification of hypervirulent strains enables better clinical management. The present study was conducted in a north Indian tertiary care hospital which receives both Indian and foreign patients. During the study period (September –December 2022), 29 isolates of K. pneumoniae were collected from Out Patients department (OPD), Intensive Care Unit (ICU) and wards. Genotypic profiling was based on Multi Locus Sequence Typing (MLST) and wzi type. Virulence was determined by PCR based screening of genes (RmpA, iucB, ybts, iroN) as well as phenotypic tests: string test, biofilm formation and serum neutralization assay. We identified 17 Sequence Type and 14 wzi strain. The most common Sequence Type was ST231 (6/29) followed by ST 6260 (3/29)0.15 (51.7%) isolates were carbapenem resistant (CR). Eleven isolates carried the aerobactin gene iucB and/or rmpA genes. The results of the study show the presence of diverse genotypes and virulence genes of K. pneumoniae, stressing the need for stricter surveillance. We also observed a significantly higher average length of stay in patients carrying hypervirulent or carbapenem resistant strains (p
