Abstract excerpt

Hypervirulent Klebsiella pneumoniae is a pathotype capable of causing invasive infections with high morbidity and mortality rates. In this study, we conducted a surveillance analysis of hypervirulent isolates circulating in Mexico to characterize their phenotypic and genomic features. Presumptive hypervirulent isolates were identified at a frequency of 6.48 % (19/293), comprising 17 K. pneumoniae sensu stricto...
