Abstract
Aim: To identify and know the antimicrobial sensitivities of the aerobic bacteria in patients with acute otitis externa (AOE).
Materials and methods: Sixty-six patients of acute otitis externa were prospectively analysed at a tertiary care centre in North-India from May 2021 to April 2022. Samples for culture and sensitivity were sent to the microbiology department and the results analysed.
Results: A total of 50 samples yielded positive results for bacterial cultures. The gram-negative isolates were 60%, and the gram-positive were 40%. Pseudomonas aeruginosa was the most common organism isolated overall (48%), followed by Staphylococcus aureus (36%). Pseudomonas aeruginosa isolates were found to be most susceptible to piperacillin + tazobactam and imipenem (100%), followed by cefepime (91.67%) and ciprofloxacin (87.5%) while the Staphylococcus aureus isolates were found to be most susceptible to linezolid (100%) and doxycycline (94.44%), followed by clindamycin (88.89%).
Conclusion: Causes of bacterial diversity and their varied anti-microbial sensitivities and increasing antimicrobial resistance due to inadvertent use of antibiotics over time has caused change in susceptibility of bacteria. It therefore becomes essential to periodically assess the microbiological flora so as to provide quality and cost-effective treatment to the patient population presenting with AOE.
期刊介绍：
Indian Journal of Otolaryngology and Head & Neck Surgery was founded as Indian Journal of Otolaryngology in 1949 as a scientific Journal published by the Association of Otolaryngologists of India and was later rechristened as IJOHNS to incorporate the changes and progress.
IJOHNS, undoubtedly one of the oldest Journals in India, is the official publication of the Association of Otolaryngologists of India and is about to publish it is 67th Volume in 2015. The Journal published quarterly accepts articles in general Oto-Rhino-Laryngology and various subspecialities such as Otology, Rhinology, Laryngology and Phonosurgery, Neurotology, Head and Neck Surgery etc.
The Journal acts as a window to showcase and project the clinical and research work done by Otolaryngologists community in India and around the world. It is a continued source of useful clinical information with peer review by eminent Otolaryngologists of repute in their respective fields. The Journal accepts articles pertaining to clinical reports, Clinical studies, Research articles in basic and applied Otolaryngology, short Communications, Clinical records reporting unusual presentations or lesions and new surgical techniques. The journal acts as a catalyst and mirrors the Indian Otolaryngologist’s active interests and pursuits. The Journal also invites articles from senior and experienced authors on interesting topics in Otolaryngology and allied sciences from all over the world.
The print version is distributed free to about 4000 members of Association of Otolaryngologists of India and the e-Journal shortly going to make its appearance on the Springer Board can be accessed by all the members.
Association of Otolaryngologists of India and M/s Springer India group have come together to co-publish IJOHNS from January 2007 and this bondage is going to provide an impetus to the Journal in terms of international presence and global exposure.
