    A carbapenem-resistant Pseudomonas aeruginosa strain (PA41437) susceptible to expanded-spectrum cephalosporins was recovered from several consecutive lower-respiratory-tract specimens of a patient who developed a ventilator-associated pneumonia while hospitalized in an intensive care unit. Cloning experiments identified OXA-198, a new class D β-lactamase which was weakly related (less than 45 ...Cited by: 51

    Carbapenem-Hydrolyzing Beta-Lactamases. The carbapenem-hydrolyzing enzymes possess the most extensive substrate profiles of all β-lactamases and are increasingly clinically important β-lactamases (38). Chromosomal enzymes capable of hydrolyzing carbapenems have been recognized without causing undue concern for a long time, but the more ...Cited by: 18

    Imipenem and meropenem are among the drugs of choice used to treat nosocomial infections due to multidrug-resistant Acinetobacter baumannii isolates. However, their efficacy is being increasingly compromised by the emergence of carbapenem-hydrolyzing β-lactamases of molecular Ambler class B (metalloenzymes) and D enzymes (oxacillinases) (1, 2, 3, 12, 17).Cited by: 148

    Carbapenems, which include the widely used antibiotics meropenem and imipenem, are used to treat severe infections caused by β-lactamase-harboring bacteria (1, 3).Unfortunately, as with other antibiotics, resistance to carbapenem antibiotics has emerged and several β-lactamases that catalyze the hydrolysis of carbapenems have been identified (9, 11).Cited by: 28
