Introduction:
Chryseobacterium gleum is commonly distributed in the environment. It can cause a wide variety of infections in immunocompromised patients in hospital setting.
Case Presentation:
A 6 month old infant with nephrotic syndrome was admitted to the emergency room for an acute onset of fever, difficulty breathing, cyanosis, and low oral intake. Cultures of endotracheal tube specimens were positive for Chryseobacterium gleum which was confirmed by ribosomal sequencing. The organism was susceptible to trimethoprim-sulfamethoxazole, minocycline, and levofloxacin. The patient clinically improved on levofloxacin treatment.
Conclusion:
To the best of our knowledge, this is the first case of pneumonia caused by Chryseobacterium gleum in an infant with nephrotic syndrome. It is also the first report of C. gleum causing respiratory tract infection in Saudi Arabia.
