Pattern of Bacterial Isolates from Chronic Suppurative Otitis Media Patients- A Microbiological Study
Journal Title: Journal of Advanced Medical and Dental Sciences Research - Year 2017, Vol 5, Issue 12
Abstract
Introduction- Chronic Suppurative Otitis Media (CSOM) is defined as chronic inflammation of the middle ear and mastoid cavity, which presents with recurrent ear discharges or otorrhea through a tympanic perforation. This study was conducted to assess aerobic bacterial distribution in CSOM isolates. Materials & Methods- The present study was conducted on 380 patients with CSOM. Aural swabs were taken from the draining ears by using a sterile swab stick before any local medication. Two sterile swabs properly labeled for each patient, were used to collect the specimen and then promptly transported to the microbiology laboratory. Results- Age group 1-10 years had 27 males and 29 females, 11-20 years had 40 males and 30 females, 21-30 years had 56 males and 45 females, 31-40 years had 34 males and 24 females, 41-50 years had 28 males and 21 females, 51-60 years had 20 males and 15 females, 61 70 years had 5 males and 6 females. The difference was non- significant (P- 0.1). 21% samples were sterile, 5% was diptheroids, 24% were gram positive cocci which include 10.8% staphylococcus aureus, 8.7% coagulase negative Staphylococci and 4.5% Streptococci. Gram negative bacilli constitute 48% which includes 12% Pseudomonas spp., 24% Escherichia coli, 8% Proteus spp. and 4% Klebsiella spp. 2% were mixed infections which includes 0.8% Klebsiella spp.+ Pseudomonas spp., 1% E.coli + Pseudomonas spp. and 0.2% Klebsiella spp. + Proteus spp. The difference was significant (P- 0.01). Conclusion- CSOM is a common disease amongst young population. Maximum number of patients was seen in age group 21-30 years. Male predominance was observed. Commonly found bacterial isolates was gram negative bacilli and gram positive cocci.
