Abstract
To the Editor—Recently, Li et al reported that an increasing proportion of hypervirulent Klebsiella pneumoniae (hvKP) among clinical K. pneumoniae isolates has been identified in China and that the hvKP strains exhibited an increasing antimicrobial resistance [1]. Our concern is that their study may have significant impact on the empiric anti-infection treatment of serious infections caused by hvKP. Therefore, we performed this study to clarify the hypermucoviscosity (HV) and antimicrobial susceptibility of clinical K. pneumoniae isolates causing pyogenic liver abscess (PLA) and metastatic infectious disease (MID). In contrast to the findings from Li et al [1], we did not find an increasing prevalence of HV and antimicrobial resistance among those isolates. Thus, there are several issues of concern that need to be discussed.
