[Sensitivity of the recent bacterial isolates to cefotaxime and other cephem antibiotics]. 1983

S Fujita, and T Yoshida, and N Okado, and F Matsubara

Antimicrobial susceptibility of 703 nonselected strains of 14 different bacterial species to cefazolin, cefmetazole, cefotiam, cefoperazone latamoxef, and cefotaxime (CTX) was examined. CTX was the most active against E. coli, Klebsiella, Serratia, P. mirabilis, H. influenzae, beta-Streptococcus group A, beta-Streptococcus group B and S. pneumoniae. On the other hand, CTX-resistant (MIC greater than or equal to 50 micrograms/ml) strains were isolated at the following frequencies: Citrobacter, 21.7%; Enterobacter, 7.7%; Serratia, 4.6%; P. aeruginosa, 40.4% and B. fragilis, 28.6%. Of the 411 strains classified as very sensitive () or moderately sensitive (++) by disk method, 405 strains (98.5%) were inhibited by less than or equal to 12.5 micrograms/ml of CTX. Only 1 strain (0.2%) was falsely classified as moderately sensitive and no strains were falsely categorized as resistant.

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.

D004352	Drug Resistance, Microbial	The ability of microorganisms, especially bacteria, to resist or to become tolerant to chemotherapeutic agents, antimicrobial agents, or antibiotics. This resistance may be acquired through gene mutation or foreign DNA in transmissible plasmids (R FACTORS).

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
