Summary
This study identified Hemophilus influenzae biotype II in chronic bronchitis patients. Findings suggest exchange between upper and lower respiratory tracts in these individuals.
Area of Science:
- Microbiology
- Pulmonary Medicine
Background:
- Hemophilus influenzae biotyping is crucial for understanding respiratory infections.
- Chronic bronchitis patients often harbor respiratory pathogens.
Purpose of the Study:
- To determine Hemophilus influenzae biotypes in adult chronic bronchitis patients.
- To compare biotypes from upper and lower respiratory tracts of individual patients.
Main Methods:
- Utilized Minitek and IDS RapID Systems for rapid biotyping of respiratory isolates.
- Analyzed biochemical reactions of Hemophilus influenzae isolates.
- Compared biotypes from transtracheal and oropharyngeal samples.
Main Results:
- 79% of isolates were identified as biotype II using the Minitek system.
- Both Minitek and IDS RapID Systems confirmed biotype II in most isolates.
- Identical biotypes were observed in paired upper and lower respiratory tract samples.
Conclusions:
- Hemophilus influenzae biotype II is prevalent in chronic bronchitis patients.
- Evidence supports the exchange of Hemophilus influenzae between the oropharynx and tracheobronchial tree.
- Rapid biotyping kits are effective for clinical isolates.
