Predictive accuracy of disk diffusion test for Proteus vulgaris and Providencia species against five newer orally administered cephalosporins, cefdinir, cefetamet, cefprozil, cefuroxime, and loracarbef.
Three members of the tribe Proteeae (Proteus vulgaris, Providencia rettgeri, and Providencia stuartii) were tested against five newer orally administered cephalosporins (cefdinir, cefprozil, cefuroxime, cefetamet, and loracarbef) by the disk diffusion and reference broth microdilution methods. One hundred strains of these organisms were tested to confirm the excessive interpretive error rates that previously had been noted for the disk diffusion test. The results indicate that the suggested disk diffusion breakpoints for cefetamet and cefuroxime were without serious interpretive errors. In contrast, loracarbef, cefdinir, and cefprozil results exceeded acceptable interpretive error rates, with very major (false-susceptible) errors of 4, 5, and 9% respectively. Loracarbef currently has a warning in the National Committee for Clinical Laboratory Standards table footnotes addressing this problem. We recommend including cefdinir and cefprozil in the list of compounds requiring this warning. In addition, MICs of cefazolin, cefaclor, and cephalothin were determined to establish whether a class MIC concept to predict susceptibility for these agents was possible. When the indole-positive Proteus strains are tested, cefazolin MICs can be used to predict MICs of all tested orally administered cephems (8 to 13% total errors, with only a 0 to 1% very major error.

Quality control guidelines for cefdinir, cefepime, cefetamet, cefmetazole, cefpodoxime, cefprozil, and clinafloxacin (CI-960) for various National Committee for Clinical Laboratory Standards susceptibility testing methods. Quality Control Study Group.
Several multilaboratory studies to determine quality control (QC) ranges for a variety of National Committee for Clinical Laboratory Standards (NCCLS) susceptibility tests are summarized. Replicate testing used multiple lots of media and antimicrobial disks in accordance with NCCLS recommendations, including the appropriate medium modifications for tests with Haemophilus spp. and Neisseria gonorrhoeae. QC ranges for MIC and disk diffusion testing of N. gonorrhoeae ATCC 49226 were proposed for cefepime, cefetamet, cefmetazole, and cefpodoxime. Disk diffusion QC ranges for Haemophilus influenzae ATCC 49247 or ATCC 49766 were recommended with cefepime, cefetamet (10- and 30-microgram disks), cefmetazole, cefpodoxime, and cefprozil. Disk diffusion QC ranges for Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922 with cefdinir and clinafloxacin and those for Pseudomonas aeruginosa ATCC 27853 with clinafloxacin were also proposed.

MIC quality control guidelines for Haemophilus susceptibility tests using cefdinir (FK482), cefepime, cefetamet, cefpirome, ceftibuten, fleroxacin, temafloxacin, clarithromycin, RP59500, and trospectomycin.
A multilaboratory study was performed to establish broth microdilution MIC quality control (QC) guidelines for 10 investigational drugs which previously demonstrated significant activity against Haemophilus influenzae. MIC QC ranges for H. influenzae ATCC 49247 with Haemophilus test medium were determined by using multiple contemporary lots of Haemophilus test medium and the National Committee for Clinical Laboratory Standards' recommended numbers of replicate tests. On the basis of these results, QC ranges (generally modal MIC +/- one log2 dilution) are proposed for cefdinir, cefepime, cefetamet, cefpirome, ceftibuten, fleroxacin, temafloxacin, clarithromycin, RP59500, and trospectomycin. The proposed QC guidelines for clarithromycin and temafloxacin were recently accepted by the National Committee for Clinical Laboratory Standards. Topics: Anti-Bacterial Agents; Cefdinir; Cefpirome; Ceftibuten; Ceftizoxime; Cephalosporins; Clarithromycin; Erythromycin; Fleroxacin; Fluoroquinolones; Haemophilus; Humans; Microbial Sensitivity Tests; Quality Control; Quinolones; Spectinomycin; Virginiamycin | 1992 |
MIC and disk diffusion quality control guidelines for Neisseria gonorrhoeae susceptibility tests of cefdinir, cefetamet, CI-960, fleroxacin, lomefloxacin, and temafloxacin.
Cefdinir (FK482), cefetamet (Ro 15-8074), CI-960, fleroxacin, lomefloxacin, and temafloxacin have potent activities against Neisseria gonorrhoeae. They were tested in a multilaboratory study to establish quality control guidelines. Quality control ranges for N. gonorrhoeae ATCC 49226 were determined by using multiple GC agar lots, three disk lots, and a number of test replicates consistent with the M23-T guidelines of the National Committee for Clinical Laboratory Standards. The MIC ranges included 2 to 4 log2 dilution steps. The recommended inhibition zone diameter ranges were generally 7 to 8 mm and included greater than or equal to 91.3% of all recorded study results.
