Factors associated with colibactin-positive K. pneumoniae isolates in Taiwan.

Data are no. (%) of isolates. Statistical comparisons by Fisher's exact test are between the pks-positive group and the pks-negative group.aK. pneumoniae strains in which the clbB and clbN were simultaneously detected by PCR with gene-specific primers are considered colibactin-positive.bK1 and K2 capsular antigens were determined by PCR detection of the K-serotype-specific wzx locus with specific primers.cK. pneumoniae strains from tissue-invasive cases that presented with the formation of liver abscesses were regarded as KLA isolates.dK. pneumoniae strains from cases associated with abscesses at non-hepatic sites, including lesions that occurred as empyema, endophthalmitis, necrotizing fasciitis, septic arthritis, along with lung, epidural, parotid, paraspinal, splenic, renal, prostate, muscle, and deep neck abscesses.eK. pneumoniae strains from non-abscess-related cases, including pneumonia without abscess, primary peritonitis, cellulitis, biliary tract infection, primary bacteremia with no original infectious foci identifiable, and catheter-related infections.
