MULTIPLE ANTIBIOTIC RESISTANCE INDEXING OF NON- FERMENTING GRAM NEGATIVE BACILLI
Journal Title: Asian Journal of Pharamceutical and Clinical Research - Year 2017, Vol 10, Issue 6
Abstract
Objective: The multiple antibiotic resistance (MAR) indexing and finding Multidrug resistant (MDR) bacteria will help to indicate the origin from high risk of contamination where the antibiotics are often used. Hence this study was carried out to give the MAR index of non-fermenting Gram negative bacilli in a tertiary care hospital which would help our infection control team also.Methods: Drug resistance was tested by Kirby bauer’s disc diffusion method. MAR index was calculated using the formula, a/b (were a= number of antibiotics to which the organism was resistant and b= total number of antibiotics to which the organism was tested).Results: Out of 240 Gram negative non-fermenters isolated, 117 (49%) strains were greater than 0.2 of MAR index, 95(81%) was from in-patient department. 73(62%) were hospitalized for more than 3 days, 44 (38%) was from surgery department. 49(42%) was wound specimen. Out of 117 multiple antibiotic resistant isolates 99 (85%) were MDR isolates.Conclusion: 51% prevalence of isolates >0.2 MAR index shows that the source of contamination can still be brought up down by proper surveillance and management with proper usage of surface and skin disinfectants especially in surgery ward where the MAR index has indicated more usage of antibiotics
