Summary
This study investigated bacteria in peritonsillar abscesses, finding anaerobes are major causes. Penicillins or cephalosporins offer the best treatment for these infections.
Area of Science:
- Otolaryngology
- Microbiology
- Infectious Diseases
Background:
- Peritonsillar abscess is a common complication of tonsillitis.
- Bacteriology of peritonsillar abscesses requires further investigation.
Purpose of the Study:
- To identify the aerobic and anaerobic bacteria involved in peritonsillar abscesses.
- To determine the etiological role of anaerobic organisms.
Main Methods:
- A bacteriologic study of 30 patients with peritonsillar abscess.
- Pus aspiration via syringe with an 18-gauge needle.
- Aerobic and anaerobic culture procedures were employed.
Main Results:
- Aerobic and anaerobic bacteria were detected in a 1:2 frequency ratio.
- Peptostreptococcus (30.2%), group A streptococci (27.9%), Peptococcus (16.3%), and Fusobacterium (9.3%) were predominant pathogens.
- Anaerobic organisms were isolated in 75% of cases.
Conclusions:
- Anaerobes play a significant etiological role in peritonsillar abscess, apart from group A streptococci.
- Penicillins or cephalosporins are recommended for optimal chemotherapeutic benefit.
