title: GES-13, a beta-lactamase variant possessing Lys-104 and Asn-170 in Pseudomonas aeruginosa.
abstract: GES-13 beta-lactamase, a novel GES variant possessing Lys-104 and Asn-170, was identified in Pseudomonas aeruginosa. bla(GES-13) was the single gene cassette of a class 1 integron probably located in the chromosome. GES-13 efficiently hydrolyzed broad-spectrum cephalosporins and aztreonam. Imipenem was a potent inhibitor of GES-13 but was not hydrolyzed at measurable rates.
