Some properties of the beta-lactamase genes in Staphylococcus epidermidis.
نویسندگان
چکیده
Eighty-three per cent of 200 different freshly isolated cultures of Staphylococcus epidermidis produced beta lactamase. Growth in the presence of acridine orange or ethidium bromide or growth at 44 C resulted in a high frequency of loss of the beta lactamase genes in some strains of S. epidermidis. The relationship between beta-lactamase production and resistance to mercuric, cadmium and arsenate ions differed from that observed in Staphylococcus aureus. It is postulated that the genes for beta lactamase in certain strains of S. epidermidis are on a plasmid.

The aim of this study was to survey the spread of beta-lactam resistance St...
متن کاملCorrelation of penicillin minimum inhibitory concentrations and penicillin zone edge appearance with staphylococcal beta-lactamase production.
Production of staphylococcal beta-lactamase was shown to be correlated with penicillin G minimum inhibitory concentrations (MICs) of greater than 0.05 microgram/ml for 97% of the Staphylococcus aureus and 99% of the Staphylococcus epidermidis strains tested. However, it is important to note that of the isolates for which MICs were equal to or less than 0.05 micro/ml, a significant percentage (1...

متن کاملL-656,575 (OCP-9-176): a novel oxacephem. In vitro activity against aerobic and anaerobic clinical bacterial isolates.
L-656,575 (OCP-9-176) is a novel oxacephem superior to ceftazidime in in vitro activity against clinical isolates of Enterobacter species, methicillin-susceptible Staphylococcus aureus and Staphylococcus epidermidis, and multiply-resistant Pseudomonas aeruginosa. Our results suggest that L-656,575 has a high affinity for penicillin binding proteins of Pseudomonas and may bind preferentially to ...
متن کاملEvaluation of the rapid penicillinase paper strip test for detection of beta-lactamase.
The penicillin-starch paper strip method was compared with the acidometric and iodometric methods for assaying beta-lactamase production, using fresh isolates of clinically important bacteria. Results obtained by the three methods were compared for rapidity, accuracy, and stability of reagents. Of the 210 isolates tested by the paper strip method, 301 isolates tested by the acidometric method, ...
