Bacteriological Finding in Chronic Suppurative Otitis Media and Antibiotic Sensitivity
Keywords:Chronic suppurative otitis media, CSOM, Antibiotic susceptibility testing.
Background: Chronic Suppurative Otitis Media(CSOM) is one of the most common infection and a major
health problem in developing countries leads to serious complications if not treated properly.
Objective: The aim of this study is to identify the most common bacterial isolates causing CSOM in our
setup to help guide the effective management of the disease. Its poor response to routine treatment and
emergence of resistance strains were the factors responsible for undertaking this study
Materials and Method: Total 88 patients were included in the study with unilateral or bilateral discharge
for more than 3 months at ending ear nose throat(ENT) outpatient department, AL-Hussein teaching hospital
in AL-Samawa city from July 2018 to December 2018 . Samples were taken by using sterile swabs and
were cultured on aerobic media and their drug susceptibility was tested by using Kirby Bauer disc diffusion
Results: Overall microbiology of 88 samples was studied. Pseudomonas aeruginosa (32.95%) was the most
common bacterial isolate, followed by staphylococcus (30.86%), Proteus mirabilis (15%), E coli (7.95%),
streptococcus pyogen (4.54%) klebsiella sp and acinoccocus sp (2.27%) enterococcus sp (3.27%).
Conclusion: Knowledge of the local bacteriological pattern and their antibiotic sensitivity is essential for
the early, effective and cost saving treatment of CSOM and to prevent the complications and development
of antibiotic resistance.
