Study on Micro-Organisms Isolated from Ear Swab: A Hospital Based Study

  • Abhijeet Kumar Sinha Associate Professor, Department. of ENT, GS Medical College & Hospital, U.P.
Keywords: Micro-Organisms, Ear Swab, Otitis media


Background: Bacteria are the commonest cause of sinusitis. Though, the route of infection is varied but the main target is the eustachian tube which leads to the nasopharynx. Due to this, the infection may arise from the nose, throat such as tonsillitis or the outer ear.

Methods: 400 total numbers of cases were included in this study. Out of 230 samples were identified as positive. This study was conducted in the department of ENT in Saraswathi Institute of Medical Sciences, Hapur.

Results: In our study, 400 total numbers of cases were included of ear swab. Out of which 57.5% cases were positive for ear swab & rest were negative. In the 230 sample 39.2% gram positive & 60.8 negative were isolated.

Conclusions: Most common prevalent bacteria isolated from chronic discharging ears were Pseudomonas aeruginosa and Staphylococcus aureus.
