Molecular characterization of BCC isolates
We identified a total of 13 BCC isolates from TCC-related VAIs; these isolates involved two species, namely B. contaminans and B. cepacia , of which B. cepacia was the predominant species (Table 5). MLST typing revealed that B. cepacia strains possessed new MLST types: ST1723 (n = 5) and ST1724 (n = 5). Most of the isolates that belonged to ST1723 were resistant to imipenem, whereas ST1724 isolates were resistant to gentamicin. Among the BCC isolates, approximately 70% were from contaminated implant devices and 30% were from blood culture. However, the study revealed no correlation between the origin of isolation and ST.
