In-vitro evaluation of carumonam (Ro 17-2301). 1986

E E Stobberingh, and A W Houben, and C P van Boven

The in-vitro antibacterial activity of carumonam (Ro 17-2301) was assessed and compared with those of aztreonam and other beta-lactam antibiotics. Carumonam was highly active against the Enterobacteriaceae and Pseudomonas strains resistant to ampicillin (MIC greater than or equal to 256 mg/l) and carbenicillin (MIC greater than or equal to 64 mg/l), respectively. The MICs of carumonam for 90% of the strains ranged between 0.25 mg/l for Klebsiella spp. to 32 mg/l for Pseudomonas spp. The antibacterial activity was minimally altered by changes of medium or inoculum size. Carumonam was resistant to hydrolysis by the plasmid-mediated and chromosomal beta-lactamases tested. Also in the microbiological assay no inactivation was observed. Carumonam was an effective inhibitor of the SHV enzyme and the chromosomal beta-lactamases tested. Against the other plasmid-mediated enzymes carumonam was not an effective inhibitor.

D001398 Aztreonam A monocyclic beta-lactam antibiotic originally isolated from Chromobacterium violaceum. It is resistant to beta-lactamases and is used in gram-negative infections, especially of the meninges, bladder, and kidneys. It may cause a superinfection with gram-positive organisms.
