Simplified Assay for Gentamicin in the Presence of Other Antibiotics

Abstract
Gentamicin concentration was estimated by using a clinical isolate of a multiple antibiotic-resistant strain of Staphylococcus epidermidis in an agar well diffusion assay. The presence of clinically attainable concentrations of cephalothin, ampicillin, carbenicillin, clindamycin, or chloramphenicol did not affect the assay.
