ISAba1 Regulated OXA-23 Carbapenem Resistance in Acinetobacter baumannii Strains in Durban, South Africa.

Aim: This study investigated the molecular mechanisms of resistance to carbapenems and cephalosporins in 24 consecutive, multidrug-resistant Acinetobacter baumannii (MDRAB) isolates collected between January and April 2015 by a private sector laboratory in Durban, South Africa.

Results: All isolates were resistant to all carbapenems tested. bla and bla genes were found in 23 isolates, while bla, bla, and bla were absent in all isolates.
