Clonal relatedness of carbapenem-resistant Acinetobacter baumannii: high prevalence of ST136 in a burn center.

Background: Carbapenem-resistant Acinetobacter baumannii (CRAB) is a global health crisis. This study aimed to determine the clonal relatedness of antibiotic-resistant A. baumannii isolates in hospitalized patients who suffered from burn wound infection.

Molecular study of metallo-β-lactamases and integrons in Acinetobacter baumannii isolates from burn patients.

Background: Productions of metallo-β-lactamases enzymes are the most common mechanism of antibiotic resistance to all beta-lactam classes (except monobactams) in Acinetobacter baumannii. MBLs are usually associated with gene cassettes of integrons and spread easily among bacteria. The current study was performed to detect the genes encoding MBLs and integron structures in A.
