Abstract:

Introduction : Infections of the middle ear and throat are very common in South India and accounts to about 40 – 50% of the total ENT out patient.

Aims : A comparative study of the throat swab culture and aural swab culture were undertaken to find out the causative organism.

Materials and Methods : In a total of 200 cases throat and aural swabs were taken, and culture was done to isolate the pathogenic organism associated with chronic suppurative otitis media (CSOM) and chronic tonsillitis.

Results : Out of 200 cases 195 (97.5%) yielded bacterial isolates and fungal isolates in 9 cases. The maximum incidence of bacterial pathogens in CSOM was found in 62 out of 200 cases (31%) and in chronic tonsillitis these were in 55 out of 200 cases (27.5%). These pathogens were seen in the age group of 6-10 years. The most common pathogenic organisms seen in CSOM and chronic tonsillitis were Pseudomonas aeruginosa, proteus mirabilis, Klebsiella species and Staphylococcus aureus.

Conclusion : The majority of infections occurred due to P. aeruginosa, P. mirabilis, Klebsiella species and S. aureus in both CSOM and chronic tonsillitis. The most common antiobiotic useful in both CSOM and chronic tonsillitis were cefotaxime, trimethoprim sulfamethoxazole gentamycin, kanamycin, netilmicin and ofloxacin.

Keywords: Otitis, Tonsilitis, Swab culture.
