Abstract:
Chryseobacterium indolegenes is a rare pathogen that causes a variety of infections in inviduals who are mostly hospitalized with severe underlying diseases. Here we present a case of C. indolegenes in a 69-year-old male with chronic obstructive pulonary disease (COPD) who was admitted to the chest disease outpatient clinic with symptoms like cough, fever and sputum production and followed up on a suspicion of pneumonia. Despite the fact that our patient did not have any history of hospitalization for at least one year, pneumonia cause was due to C. indolegenes. Clinicians should pay attention to the rare pathogens such as C. indologenes while managing COPD patients without prior hospitalization history.
Insights
Chryseobacterium indolegenes, a rare bacterium, caused pneumonia in a chronic obstructive pulmonary disease (COPD) patient. This case highlights the need to consider rare pathogens in COPD management, even without recent hospitalization.
Area of Science:
- Medical Microbiology
- Infectious Diseases
- Pulmonology
Background:
- Chryseobacterium indolegenes is an infrequent cause of infection, typically affecting hospitalized patients with significant comorbidities.
- Chronic obstructive pulmonary disease (COPD) patients are susceptible to various respiratory infections.
