细菌产生的β-内酰胺酶，可借助其分子中的丝氨酸活性位点，与β—内酰胺环结合并打开β—内酰胺环，导致药物失活。. 迄今为止报道的 Se hela listan på sciencedirect.com Beta Lactamase accelerates the reactions between specific chemicals and is capable of breaking particular molecular structures. A B-Lactam ring is a four-atom ring, which is present in numerous B-Lactam antibiotics, such as cephalosporins, carbapenems, cephamycins, and penicillins. β--lactamase is used to inactivate β-lactam antibiotics by breaking open the β-lactam ring. β--lactamase is used to study antibiotic resistance and resistance suppression. Product L6170 is recombinantly produced based on the sequence of the enzyme from Pseudomonas aeruginosa, and is expressed in E. coli.

Klinisk prövning på Urinary Infection: Deescalation therapy

In this introductory description of the β-lactams, the most commonly available β-lactams and BLIs will be presented, with a brief summary of their general characteristics. Beta-lactamase -producing bacteria (BLPB) can play an important role in polymicrobial infections.

Antibacterial agents and development of resistance - Quizlet

When these agents were threatened by the rapid emergence of β-lactamases, β-lactamase-stable agents were developed, as well as potent β-lactamase inhibitors (BLIs). Extended-spectrum beta-lactamases are specific enzymes released by a bacteria that neutralizes the effects of antibiotics. Beta-lactamase-producing bacteria (BLPB) can play an important role in polymicrobial infections. They can have a direct pathogenic impact in causing the infection as well as an indirect effect through their ability to produce the enzyme β-lactamase. BETA-LACTAMASE (CEFINASE) TEST Principle Cefinase discs are intended for use in rapid testing of isolated colonies of Neisseria gonorrhoeae, Staphylococcus species, Enterococcus species, Hameophilus influenzae and anaerobic bacteria for the production of beta-lactamase. The Cefinase disc is impregnated with the chromogenic cephalosporin, Nitrocefin.
