Drug Inactivation by Structure Modification (DISM)

Key Molecule: Beta-lactamase (BLA) [1]

• Molecule Alteration: Expression; Inherence
• Resistant Disease: Rhodobacter sphaeroides infection [ICD-11: 1A00-1C4Z]
• Experimental Note: Discovered Using In-vivo Testing Model
• In Vitro Model: Rhodopseudomonas sphaeroides strain DSM 160(Y); 1063
• In Vitro Model: Rhodopseudomonas sphaeroides strain DSM158; 1063
• In Vitro Model: Rhodopseudomonas sphaeroides strain DSM159; 1063
• Experiment for Molecule Alteration: Sodium dodecyl sulfate-PAGE assay
• Experiment for Drug Resistance: MIC assay
• Mechanism Description: Thirteen strains of the gram-negative, facultative phototrophic bacterium Rhodobacter sphaeroides were examined fro susceptibility to beta-lactam antibiotics. All strains were sensitive to the semisynthetic penicillins ampicillin, carbenicillin, oxacillin, cloxacillin, and methicillin, but 10 of the 13 strains were resistant to penicillin G, as well as a number of cephalosporins, such as cephalothin, cephapirin, and cephalosporin C. A beta-lactamase (EC 3.5.2.6) with strong cephalosporinase activity was detected in all of the resistant strains of R. sphaeroides. With strain Y-1 as a model, it was shown that the beta-lactamase was inducible by penicillin G, cephalosporin C, cephalothin, and to some minor extent, cephapirin.
