WebbThe first-generation cephalosporins (e.g., cefazolin, a parenteral formulation, and cephalexin, an oral equivalent) are commonly used for management of skin and soft tissue infections caused by susceptible strains ofS. aureus and group A streptococcus. WebbTwo distinct enzymes are produced: the A1 enzyme, a serine beta-lactamase behaving as a group 1 cephalosporinase, and the A2 enzyme, a metallo beta-lactamase which hydrolyses a wide range of beta-lactam agents including the carbapenems. The clinical relevance of these enzymes in Aeromonas spp. is unclear. Publication types Review

WebbBoth isolates were unstable, giving rise to different colony types, each of which produced a single, non-inducible Bush group 1 beta-lactamase (pI = 9.6) that hydrolyzed imipenem. Outer membrane proteins were analyzed but no differences were detected between strains with different levels of imipenem resistance. WebbOverview. Beta-lactamases are enzymes ( EC 3.5.2.6) produced by some bacteria and are responsible for their resistance to beta-lactam antibiotics like penicillins, cephalosporins, cephamycins and carbapenems. These antibiotics have a common element in their molecular structure: a four-atom ring known as a beta-lactam.

WebbImipenem resistance in Ps. aeruginosa can occur following selection of mutants that hyperproduce the group 1 cephalosporinase and which are also deficient in an outer membrane protein (OprD or D2) which specifically transports imipenem, but not cephalosporins or monobactams.
