A Study on bacteriological profile and the antibiotic susceptibility pattern in cases of chronic suppurative otitis media in Haroti region

Abstract

Introduction: Chronic suppurative otitis media (CSOM) is one of the common hearing problems which can cause many complications if not treated properly. Hence, the study aims to identify the bacterial isolates causing CSOM and to study their antimicrobial susceptibility pattern. Materials and Methods: The study was carried out in a tertiary care hospital in Kota from May 2019 to January 2020. Three hundred and seventy patients of CSOM with discharge attending the ENT outpatient department were included in the study. Swabs were taken and sent immediately to the microbiology laboratory and processed. Bacterial isolates were identified using standard methods and antibiotic susceptibility testing was done. Results: Pseudomonas was the most predominant bacteria isolated followed by Staphylococcus aureus, Coagulase-negative Staphylococcus, Enterobacter spp., Proteus spp., Streptococcus pneumonia, Klebsiella spp., Enterococcus and Acinetobacter spp. Conclusions: The present study helped in knowing the bacteriological profile of the cases of CSOM. Empirical treatment may not be successful in all cases because of the emergence of resistant organisms. Hence, it is advisable to do an antibiogram before starting the treatment.
