In-vitro activity of cefoperazone-sulbactam against Bacteroides species. 1986

M B Souza Dias, and N V Jacobus, and F P Tally

The in-vitro activity of two combinations of sulbactam and cefoperazone against 187 strains of Bacteroides fragilis were evaluated; their activity was compared with that of the drugs alone, and correlated with the production of beta-lactamase by the bacterial strains. The results indicated that both combinations had a synergistic effect: the addition of 8 mg/l of sulbactam to the MIC of cefoperazone reduced the percentage of resistant strains from 58% to 0.5%; while the combination of two parts of cefoperazone to one pact of sulbactam lowered the resistance rate to 1%. Synergy was observed most frequently with beta-lactamase positive strains, but it also occurred among beta-lactamase negative strains.

D001421	Bacteria, Anaerobic	Bacteria that can survive and grow in the complete, or nearly complete absence of oxygen.	Anaerobic Bacteria
D001439	Bacteroides	A genus of gram-negative, anaerobic, rod-shaped bacteria. Its organisms are normal inhabitants of the oral, respiratory, intestinal, and urogenital cavities of humans, animals, and insects. Some species may be pathogenic.
D001618	beta-Lactamases	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.	beta-Lactamase,beta Lactamase,beta Lactamases
D013407	Sulbactam	A beta-lactamase inhibitor with very weak antibacterial action. The compound prevents antibiotic destruction of beta-lactam antibiotics by inhibiting beta-lactamases, thus extending their spectrum activity. Combinations of sulbactam with beta-lactam antibiotics have been used successfully for the therapy of infections caused by organisms resistant to the antibiotic alone.
