In vitro activity of Ro 15-8074 and Ro 19-5247 in comparison to cefaclor and cefalexin. 1987

C Simon

805 clinical isolates were investigated for their in vitro sensitivity against Ro 15-8074 and Ro 19-5247 in comparison to cefaclor and cefalexin in a serial dilution test on solid medium. Ro 19-5247 had the strongest activity of all drugs tested against streptococci (except Streptococcus faecalis) and was as active as cefaclor and cefalexin against most strains of Staphylococcus aureus. Ro 19-5247 was the only oral cephalosporin active against Bordetella pertussis. It was on average 160 times more active than cefaclor against Haemophilus influenzae. In its activity against enterobacteria Ro 19-5247 was always superior to cefaclor and cefalexin. Only a few strains of Enterobacter aerogenes, Enterobacter cloacae, Klebsiella pneumoniae, Proteus vulgaris and Serratia marcescens were resistant to Ro 19-5247 as were all strains of Enterobacter agglomerans and Klebsiella ozaenae. Ro 15-8074 was inactive against staphylococci but ten times more active than cefaclor and cefalexin against Streptococcus pyogenes. There was no difference in the activity against Streptococcus pneumoniae and Streptococcus agalactiae. Against Haemophilus influenzae Ro 15-8074 acted 12 times stronger than cefaclor and 100 times stronger than cefalexin. The activity against enterobacteria corresponded to that of Ro 19-5247. Ro 15-8074 was also active against most strains of Enterobacter cloacae and Proteus vulgaris which were resistant to cefaclor and cefalexin.

D002511	Cephalosporins	A group of broad-spectrum antibiotics first isolated from the Mediterranean fungus ACREMONIUM. They contain the beta-lactam moiety thia-azabicyclo-octenecarboxylic acid also called 7-aminocephalosporanic acid.

D001419	Bacteria	One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.	Eubacteria

D015281	Cefmenoxime	A cephalosporin antibiotic that is administered intravenously or intramuscularly. It is active against most common gram-positive and gram-negative microorganisms, is a potent inhibitor of Enterobacteriaceae, and is highly resistant to hydrolysis by beta-lactamases. The drug has a high rate of efficacy in many types of infection and to date no severe side effects have been noted.

D015296	Ceftizoxime	A semisynthetic cephalosporin antibiotic which can be administered intravenously or by suppository. The drug is highly resistant to a broad spectrum of beta-lactamases and is active against a wide range of both aerobic and anaerobic gram-positive and gram-negative organisms. It has few side effects and is reported to be safe and effective in aged patients and in patients with hematologic disorders.
