Pneumonia due to Haemophilus influenzae (H. aegyptius) biotype 3
Journal of Clinical Microbiology
|August 1, 1977
Abstract:
Haemophilus influenzae (H. aegyptius) biotype 3 was isolated from eye, nasopharyngeal, and sputum cultures of a 23-month-old male and from sputum and transtracheal aspirate cultures of his 39-year-old mother, both with diffuse bronchopneumonia.
Insights
Haemophilus influenzae biotype 3, a bacterium, was identified in respiratory and eye cultures from a child and his mother. Both patients had diffuse bronchopneumonia, suggesting a potential link between this specific bacterial strain and the lung infection.
Area of Science:
- Microbiology
- Infectious Diseases
- Pulmonary Medicine
Background:
- Haemophilus influenzae is a bacterium that can cause various infections.
- Biotype 3 of H. influenzae (H. aegyptius) has been implicated in specific disease presentations.
Observation:
- The bacterium Haemophilus influenzae (H. aegyptius) biotype 3 was isolated from multiple culture sites.
- Samples were obtained from a 23-month-old male (eye, nasopharyngeal, sputum) and his 39-year-old mother (sputum, transtracheal aspirate).
Findings:
- Both the child and his mother presented with diffuse bronchopneumonia.
- The isolation of H. aegyptius biotype 3 from these patients suggests its etiological role in their pneumonia.
Implications:
- This case highlights the potential for H. aegyptius biotype 3 to cause severe respiratory illness in both children and adults.
- Further research may clarify the specific pathogenic mechanisms and transmission patterns of this organism.
