Bacteriological findings and antibiotic susceptibility profile of chronic suppurative otitis media in Mukalla, Yemen

ABSTRACT

Chronic suppurative otitis media [CSOM] is one of the most common diseases of all age groups, especially on childhood. To identify bacterial isolates and determine their antibiotic susceptibility patterns. This retrospective study was carried out at a private Ear, Nose and Throat Clinic in Mukalla. The bacteriological reports of ear swabs of all patients with CSOM during the period 2004 to 2010 were included in the study. Isolates were tested for their susceptibility to 15 antibiotics. Data analysis was carried out using SPSS 17. A total of 218 bacteriological reports were with a single isolate. Male to female ratio was 1.21. peak-age incidence of CSOM was mostly in children younger than 15 years of age, [p > 0.05]. Most common bacteria isolated were, Proteus species [46.7%], Pseudomonas aeruginosa [37.2%] and Saphylococcus aureus [11%]. Both gram positive and negative isolated bacteria were resistant with a range of intermediate to high-level, to ampicillin, amoxicillin, augmentin, cefotaxime, bactrim, erythromycin, ofloxacin and gentamicin but were sensitive to amikacin, chloramphinicol, ciprofloxacin, norfloxacillin, lincomycin and cephaclor,. Most of the patients in the series were children less than 15 years of age and gram negative bacteria were predominant. More comprehensive studies are required to define the true magnitude of CSOM.
