Resistance to beta-lactam antibiotics Proteus strains.
Acta microbiologica Polonica. Series A: Microbiologia generalis, 1976A total of 218 Proteus strains isolated from clinical sources were tested for their susceptibility to three penicillins and two cephalosporins. The ability to beta-lactamase production was examined in 36 of these strains. Proteus mirabilis strains were generally more susceptible to cephalosporins than to penicillins, whereas indole-positive Protei were

Mechanisms of resistance to beta-lactam antibiotics.
Scandinavian journal of infectious diseases. Supplementum, 1991The use of new beta-lactam antibiotics has led to selection of novel forms of resistance. Newer-generation cephalosporins, ureidopenicillins and monobactams, but not carbapenems (e.g. imipenem), are labile to Class I chromosomal beta-lactamases and tend to select mutants of E. cloacae and P.

Trends in beta-lactam resistance among Enterobacteriaceae
1998beta-Lactam resistance among Enterobacteriaceae is related primarily to the emergence of novel beta-lactamases. The class A extended-spectrum beta- lactamases hydrolyze extended-spectrum beta-lactams and are inhibited by clavulanic acid. These beta-lactamases are divided in two groups: TEM and SHV derivatives and non-TEM and non-SHV extended-spectrum ...

[Mechanisms of resistance to beta-lactam antibiotics].
Infection, 1994Beta-lactam antibiotics share the structural feature of a beta-lactam ring. This feature is responsible for inhibition of bacterial cell wall synthesis. The target molecules are peptidoglycan cross-linking enzymes (e.g. transpeptidases and carboxypeptidases) which can bind beta-lactam antibiotics (penicillin binding proteins, PBP). Bacterial cell death
