The resistance of bacteria to beta-lactam antibiotics was first associated with the production of the enzyme beta-lactamase as long ago as 1940. Since then, increasing numbers of beta-lactamase-producing bacteria capable of inactivating penicillins and cephalosporins have been isolated clinically. One approach to the problem posed by beta-lactamase-producing bacteria has been to seek substances that function as inhibitors of beta-lactamase and that can be used to protect beta-lactam antibiotics… 
Inhibition of beta-lactamase enzyme of Pseudomonas aeruginosa by clavulanic acid of Rumex vesicarius L.
Beta-lactamase inhibitor was purified and characterized as clavulanic acid by using nuclear magnetic resonance (NMR) spectroscopy analysis, infra-red (IR) spectrapopy analysis and elemental analysis, and eventually, amoxicillin-resistant P. aeruginosa was inhibited by am toxicillin-clavULanic acid combination at 125 µg ml -1 and 128 mg ml - 1 , respectively.
The inhibitory effect of Streptomyces chromofuscus on β-lactamase of Pseudomonas aeruginosa ATCC-10145
Two Streptomyces isolates were screened for producing β-lactamase inhibitory effect against P. aeruginosa ATCC-10145 and one of these isolates was considered the most potent, this was identified by using biochemical characteristics as StrePTomyces chromofuscus.
Efficacy and Cost of Ampicillin‐Sulbactam and Ticarcillin‐Clavulanate in the Treatment of Hospitalized Patients with Bacterial Infections
This study evaluated the efficacy and cost of treatment with two β‐lactam/β‐ lactamase‐inhibitor combinations and found that the former was more effective and the latter less effective.
Directed molecular evolution of fourth-generation cephalosporin resistance in
Substantial differences in the ways that usage guides treated usage problems and in the attitudes bloggers and journalists espoused towards usage problems are revealed in this chapter.

Results suggest that the beta-lactam/beta- lactamase-inhibitor combination ampi-cillin/sulbactam is cost-effective for perioperative treatment of patients undergoing head and neck surgery.
