Bacteriological study of discharging ear in patients attending a tertiary care hospital
Keywords:
Bacteriology, Ear infection, Pseudomonas aeruginosa, Culture & sensitivityAbstract
Ear infections occur in all age groups. Chronic Suppurative Otitis Media (CSOM) is the most common illness in ENT practice. It may even cause hearing impairment especially sensory – neural deafness if not treated properly and with caution. The study was undertaken to know the aerobic microbiological/bacteriological profile of ear discharge and variations in sensitivity pattern to treat the patients efficiently. A total of 71 patients who had discharging ear infection were included in this study. The most common microorganisms isolated were Pseudomonas aeruginosa and Staphylococcus aureus followed by Coagulase-Negative Staphylococci (CoNS), Klebsiella spp, Proteus spp and Escherichia coli. Among the commonly used topical antibiotics, Ciprofloxacin appear to be first line antibiotic (91.52% sensitive) to treat CSOM followed by Gentamycin (89.6% sensitive). However, the action of Chloramphenicol was low (59.53% sensitive). Ofloxacin can be used to treat CSOM due to Staphylococcus aureus other than Ciprofloxacin and Gentamycin.
