Beta-Lactamase Stability of Faropenem
Chemotherapy, 2003Faropenem (FAR) is an orally available member of the penem class unique among carbapenems and other available β-lactams. This study compared FAR to cephalosporins and imipenem with respect to β-Iactamase (BLA) stability and emergence of resistance to <i>Staphylococcus aureus </i>and <i>Escherichia coli</i>.

Presence of Beta-Lactamase–Producing Bacteria and Beta-Lactamase Activity in Abscesses
American Journal of Clinical Pathology, 1986The presence of beta-lactamase-producing bacteria (BLPB) in abscesses was investigated in 109 abscesses. Single isolates were recovered in 23 (21%) instances and were predominantly Staphylococcus aureus. The other abscesses yielded growth of two or more aerobic and/or anaerobic organisms.

Importance of beta-lactamase induction
European Journal of Clinical Microbiology & Infectious Diseases, 1993Induction of an enzyme is a temporary phenomenon in which the rate of enzyme synthesis is greatly increased in response to the presence of an inducer in the environment. Induction of beta-lactamase synthesis is important for the resistance of staphylococci to penicillins since the drug both induces synthesis of the enzyme and is hydrolysed by it ...

Beta-lactamases and beta-lactamase inhibitors.
International journal of antimicrobial agents, 1999Penicillin, the first of the beta-lactam antibiotics, was introduced into medical practice in the 1940s. Since then, a large number of different beta-lactams, including penicillins, cephalosporins, monobactams, and carbapenems, have been developed, all of which are structurally related through the presence of a core beta-lactam ring. Resistance to beta-

Contribution of beta-lactamases to bacterial resistance and mechanisms to inhibit beta-lactamases
The American Journal of Medicine, 1985Resistance of bacteria to beta-lactam antibiotics has become a serious problem in the past several decades. Virtually all Staphylococcus aureus, and many Hemophilus influenzae, Branhamella catarrhalis, Neisseria gonorrhoeae, Enterobacteriaceae, and Bacteroides species possess beta-lactamases that hydrolyze penicillins and cephalosporins.
