Summary
Bacteriology in adenoid disease shows common bacteria like Haemophilus influenzae and diphtheroids in both hypertrophy and chronic adenoiditis. No significant differences in organism distribution or counts were found between the two conditions.
Area of Science:
- Microbiology
- Pediatric Otolaryngology
Background:
- Adenoid disease encompasses adenoid hypertrophy and chronic adenoiditis.
- Understanding the bacterial landscape of adenoids is crucial for diagnosis and treatment.
Purpose of the Study:
- To define the differential bacteriology in adenoid disease.
- To compare bacterial findings in adenoid hypertrophy versus chronic adenoiditis.
Main Methods:
- Adenoid tissue samples were collected from 39 children (10 with hypertrophy, 29 with chronic adenoiditis).
- Surface disinfection followed by aerobic and anaerobic culture of 1 gram of tissue.
- Bacterial isolates and colony counts were analyzed.
Main Results:
- An average of 4.8 isolates per specimen were found, predominantly aerobes (4.2) over anaerobes (0.6).
- Common isolates included Haemophilus influenzae (84%), diphtheroids (66%), and streptococci species (64-59%).
- No significant differences in organism distribution or total colony counts were observed between chronic adenoiditis and adenoid hypertrophy.
Conclusions:
- The bacteriology of adenoid tissue is similar in both chronic adenoiditis and adenoid hypertrophy.
- Commonly isolated bacteria do not differentiate between these two clinical presentations of adenoid disease.
