Bacteriological and mycological study of chronic suppurative otitis media
Journal Title: Medpulse International Journal of Microbiology - Year 2018, Vol 8, Issue 3
Abstract
Background: Chronic suppurative otitis media (CSOM) is an inflammation of the middle ear and mastoid mucosa with perforation of tympanic membrane. CSOM disease of developing countries. CSOM results because of illiteracy, poverty and poor hygiene. Haphazard use of antibiotics and increasing use of newer one has led to persistent change in microbial flora. The aim of this study is to determine the incidence of CSOM and its causative agents. Methods: Ear discharge from 150 patients attending ENT OPD of Yashavantrao Chavhan rural hospital Latur, suffering from CSOM and diagnosed by ENT surgeon was taken. Samples were processed in microbiology department for both bacteria and fungi using standard operating protocol. Antibiotic susceptibility testing was performed for all bacterial isolates by Kirby Bauer disc diffusion method and the result were interpreted according to clinical and laboratory standard institute (CLSI) guideline. Results: Out of 150 patients, 80 were male and 70 female patients. Highest incidence of CSOM was observed between 11-20 years of age group. One hundred and fifty three ear swabs were collected from 150 cases (3 cases of Bilateral CSOM) and examined. On culture they yielded 186 isolates, out of which 150 (80.64%) were bacterial and 36(19.36%) were fungal, the first commonest isolate was Staphylococcus aureus 59 (31.72%) followed by Pseudomonasaeruginosa. 50(26.88%), Klebsiella spp. 21(11.29%), Coagulase negative Staphylococci (CONS) 6(3.23%). Among fungal isolates the commonest isolate was Aspergillus niger 15 (8.06%), followed by Candida albicans 9 (4.84%), Aspergillus fumigatus 5(2.69%), Aspergillus flavus 3 (1.61%), Mucor 2 (1.07%), The first commonest isolate S. aureus 59 (31.72%) showed highest sensitivity to linezolid 59 (100%) followed by gentamicin 49 (83.05%), Pseudomonas aeruginosa was found sensitive to imipenem 88% followed by klebsiellaspp and proteus were found sensitive to imipenem 96.96 %. Conclusion: S. aureus was the most predominant organism followed by Peudomonas the drug of choice was Levofloxacin and Gentamicin.
