Inability of cephalothin testing to predict cefprozil susceptibility

Inability of cephalothin testing to predict cefprozil susceptibility.

The 30-micrograms cefprozil disk and the cephalosporin class (30-micrograms cephalothin) disk were compared for their abilities to predict cefprozil susceptibility by agar disk diffusion testing. High error (5.02% major and 14.11% minor) rates were encountered with the cephalothin disk and were most frequently observed for Escherichia coli and Enterococcus faecalis. The cefprozil disks resulted...

Inability to predict relapse in acute asthma.

Susceptibility of clinical isolates of bacteria to cefoxitin and cephalothin.

The susceptibility of 4,929 unselected clinical isolates of bacteria to cefoxitin and cephalothin was determined by the single-disk method, using a computer-associated electronic zone analyzer to obtain, record, and process measurements of sizes of zones of inhibition. Both cefoxitin and cephalothin were effective against most gram-positive strains, including Staphylococcus aureus, S. epidermid...

Disk susceptibility studies with cefazolin and cephalothin.

Cefazolin and cephalothin disk susceptibility and minimal inhibitory concentration determinations were conducted on 591 clinical isolates. Cefazolin demonstrated superior activity, as shown by lower minimal inhibitory concentrations, and a greater percentage of isolates inhibited in the disk susceptibility test. The cephalothin antibiotic class disk by the standard Bauer-Kirby method failed to ...

Insenstivity to close contacts and inability to predict protein foldability.

Mittal and coworkers recently (1) analyzed the spatial organization of folded proteins backbone and advocated an alternative hypothesis on protein folding stating that specific interactions among amino acids do not drive protein folding. The authors analyzed spatial distributions of Cα atoms for all amino acid pairs in about four thousands proteins available in PDB database and they found that ...
