Identification and characterization of carbapenemase genes in clinical isolates of carbapenem-resistant Acinetobacter Baumannii from general hospital in Thailand.

This study identified, using PCR blaoxA,,23 encoding carbapenamase OXA-23 in 42 carbapenem-resistant Acinetobacter baumannii (CRAB) clinical iso- lates and blaOXA-40-like encoding carbapenamase OXA-40-like in one isolate (the first such Thai sample) obtained from patients admitted to Hua Hin Hospital, Thailand during November 2011-September 2012. Using repetitive extragenic palindromic PCR, the isolates could be divided into 4 different clones, with 40 isolates belonging to clone A and the remaining to B, C and D. Other resistance in CRAB needs to be investigated.
