Microbiological agar diffusion assay for metronidazole concentrations in serum.

An agar diffusion method using paper disks on plates seeded with Clostridium perfringens and incubated anaerobically to assay serum levels of metronidazole is described. The lowest serum metronidazole concentration that could be measured was 0.7 mug/ml, and the average error was 4% for 5 mug/ml. This assay could measure metronidazole in the presence of gentamicin or in the presence of penicilli...

Disc-agar diffusion microbiological assay procedure for determining serum and urine levels of sulfacytine and other sulfonamides.

A reasonably precise, reproducible, and sensitive microbiological procedure for directly assaying sulfacytine and other sulfonamides as antibacterially active drugs has been developed by appropriately modifying the standard disc-agar diffusion technique. Blood and urine levels as low as 3 mug/ml may be determined through the use of a strain of Escherichia coli and a chemically defined agar medi...

Comparison of three experimental designs employed in gentamicin microbiological assay through agar diffusion

Gentamicin is a broad-spectrum antibiotic complex produced by actinomycetes belonging to Micromonospora genus and classified among aminoglycoside antibiotics, used in the treatment of serious infections derived from Gram-negative microorganisms. Alterations of their antimicrobial activity not shown in chemical assays can be evaluated through microbiological assays. The aim of this work was to c...

Lecithin-agar assay for lecithinase antibodies in serum.

A technique for assay of lecithinase antibodies in serum was developed in this laboratory by using a lecithin-agar plate diffusion procedure based on a combination of described plate assays. Egg yolk lipoprotein composed primarily of lecithin was used as a substrate for reaction with free or non-neutralized lecithinase C after incubation of known amounts of lecithinase C with various dilutions ...

Comparison of a radioimmunoassay and a microbiological assay for measurement of serum vancomycin concentrations.

A newly developed radioimmunoassay was used to measure the concentration of vancomycin in 137 specimens of serum from patients being treated with this antibiotic. Of these sera, 84 were also analyzed with a microbiological assay technique for vancomycin. Duplicate determinations were done with each of the techniques. Individual values and averaged values for both methods were used for statistic...
