Background and Objectives : It is important to know the species of pathogens and its antibiotic susceptibility in the treatment of chronic suppurative otitis media. Recently the incidence of Methicillin resistant Staphylococcus aureus (MRSA) infection has been increasing and systemic Vancomycin or Teicoplanin injection may accompany inconvenience and high medical costs. The objective of this article is to evaluate the current bacteriology of chronic suppurative otitis media. Materials and Method : We evaluated the bacteriologic results of 188 out-pa-tients of chronic otitis media with otorrhea between Jan 2001 and Dec 2004. Results : A total of 194 isolates were recovered. The most common pathogenic organism was Staphylococcus aureus (41.2%), followed by Pseudo-monas (22.7%), Staphylococcus (Coagulase negative)(13.4%), and Streptococcus pneumoniae (7.7%). The prevalence of MRSA was 57.5% out of the isolated Staphylococcus aureus. MRSA was highly susceptible to Vancomycin, Aberkacin, ulfamethoxazole/trimethoprim (Bactrim). Conclusion : We investigated the current bac-teriology of chronic suppurative otitis media and could not find remarkable differences from the other results re-ported recently.
