Bacterial patterns in chronic suppurative otitis media have shifted, with Pseudomonas and methicillin-resistant Staphylococcus aureus (MRSA) now predominant. Ongoing surveillance is crucial for effective antibiotic treatment guidance.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Microbiology
Background:
- Antibiotic development has altered microbial landscapes.
- Understanding current pathogens is vital for treating chronic suppurative otitis media (CSOM).
Purpose of the Study:
- To investigate the current bacteriology of CSOM.
- To identify prevalent pathogens and their antibiotic resistance patterns.
Main Methods:
- Retrospective study.
- 1102 patients with CSOM.
- Data collected from six Korean hospitals (2001-2005).
Main Results:
- Pseudomonas was the most frequently isolated pathogen.
- Methicillin-resistant Staphylococcus aureus (MRSA) was the second most prevalent.
- Identified shifts in bacterial predominance.
Conclusions:
- Bacterial predominance and antibiotic sensitivity in CSOM have evolved.
- Continuous and periodic surveillance is essential.
- Informed antibacterial therapy requires up-to-date microbiological data.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
