Abstract
Antibiotics have been used for treatment of many infections since decades. But all antibiotics cannot be used for all infections. So, the susceptibility of the organisms to the antibiotics needs to be checked. For this purpose, disc diffusion technique has been used. In this study, low cost antibiotic discs are prepared by impregnation of antibiotic solution onto whatman filter paper grade 3. After the preparation of the disc, they are standardized by comparing their efficacy with the commercially available discs. But the major concern is about the growing resistance of microorganisms to the currently available antibiotics. Hence an attempt has been made to study the resistance pattern of the clinical isolates in the given period using low cost antibiotic discs.
