| beta-lactamase | <enzyme> An enzyme produced by some bacteria, which causes the breakdown of the active form of some penicillin antibiotics, rendering them ineffective. It causes the hydrolysis of a beta-lactam (as penicillin to penicilloic acid); found in most strains of staphylococcus bacteria that are naturally resistant to penicillin. Synonym: cephalosporinase, penicillinase. (05 Mar 2000) |

| beta-lactamase inhibitor | <pharmacology> Drugs such as clavulanic acid, which are used to inhibit bacterial beta-lactamases; often used with a penicillin or cephalosporin to overcome drug resistance. (05 Mar 2000) |
| beta-lactamases | <enzyme> Enzymes found in many bacteria which catalyze the hydrolysis of the amide bond in the beta-lactam ring. Well known antibiotics destroyed by these enzymes are penicillins and cephalosporins. Chemical name: beta-Lactamhydrolase Registry number: EC 3.5.2.6 (12 Dec 1998) |
Synonyms : beta-Lactamase, beta Lactamase, beta Lactamases
| beta-lactamase |

| beta-lactamase resistance |
The ability of microorganisms that produce the enzyme beta-lactamase, also called penicillinase, to resist the action of certain types of antibiotics, including some but not all forms of penicillin.

| beta-lactamase resistant penicillin |
Synthetic penicillins that resist the action of the enzyme beta-lactamase, produced by some microorganisms. Bacteria that produce the enzyme are not susceptible to the action of non?beta-lactamase resistant pe

| beta-lactamase-resistant antibiotics |
Antibiotics that are resistant to the action of ¥â-lactamase. This property makes them effective against microbial organisms that produce ¥â-lactamase. SEE: beta-lactamase resistant penicillin.
