Multidrug Resistant Bacteria Colonizing Medical Devices In The I.C.U’s Of A Pediatric Tertiary Care Centre : An Observation By Biofilm Detection .
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 10
Abstract
Biofilms are a group of organisms that attach to a surface in an exopolysacharide matrix and render them resistant to many group of antibiotics. Indwelling medical devices are often colonized by microorganisms and have a great potential towards biofilm formation.All the medical devices i.e. Intravenous catheters tips (I.V.C.), Endotracheal tubes(E.T.T.), Intercostal drain tubes(I.C.D.) and Nasogastric tubes (N.G.T. Tubes) were collected aseptically and sent to the Clinical Microbiology Laboratory. The devices were processed by standard microbiological procedures & their biofilm production was determined . In the 100 devices processed, 57% were culture positive. Staphylococcus epidermidis (45%), & Klebsiella pneumoniae (38%) were the commonest isolates , among which 81% were biofilm producers. All the Gram Positive isolates were found to be Methicillin resistant and in the Gram Negative isolates , 76% were Extended Spectrum Beta Lactamases ( E.S.B.L.) and 59% were Carbepenamase producers . From the culture positive devices 81% were biofilm producers. To conclude, among the isolates which colonized the various medical devices , majority of them were Multi Drug Resistant , which were observed to produce strong to moderate biofilms.
