Epidemiology and genetic characterization of <i>tet</i>(X4)-positive <i>Klebsiella pneumoniae</i> and <i>Klebsiella quasipneumoniae</i> isolated from raw meat in Chengdu City, China.

ABSTRACT: The rapid spread of mobile tigecycline resistance presents a significant public health threat, particularly with the increasing prevalence of tet(X4)-positive Enterobacterales across various species. This study aimed to investigate the epidemic features and transmission dynamics of tet(X4)-positive Klebsiella pneumoniae (K. pneumoniae) through the analysis of 206 raw meats, including pork (n = 182), beef (n = 16), duck (n = 5), and chicken (n = 3). These samples were collected from schools, markets, and restaurants in Chengdu City, China. A total of 25 isolates were obtained from 13 administrative regions. All isolates exhibited resistance to tetracycline, tigecycline, ampicillin, chloramphenicol, and florfenicol. Over half of
