Patent ID: 8232059

Claim:
A method for identifying an isolate as a member of a subgroup of A. baumannii with antibiotic drug resistance, comprising the steps of: a) obtaining a sample from a patient; b) identifying an isolate from the sample as A. baumannii; c) screening the isolate for genes encoding an OXA-51-like enzyme; d) sequencing any genes encoding an OXA-51-like enzyme; and e) identifying the isolate as a member of the subgroup of A. baumannii having antibiotic drug resistance when the sequence of the gene encoding an OXA-51-like enzyme determined in d) is OXA-90 (SEQ ID NO: 1), OXA-130 (SEQ ID NO: 2), OXA-131 (SEQ ID NO: 3), or OXA-132 (SEQ ID NO: 4).
