Summary
This case report details a urinary tract infection with bacteremia caused by Aerococcus viridans in an elderly male. Increased awareness of this rare pathogen is crucial for accurate diagnosis and treatment of such infections.
Area of Science:
- Microbiology
- Infectious Diseases
- Clinical Medicine
Background:
- Aerococcus viridans are gram-positive cocci commonly found in hospital environments.
- This bacterium is an infrequent cause of human infections like bacteremia and urinary tract infections.
- Its clinical significance may be underestimated due to difficult culture and resemblance to streptococci.
Observation:
- A case of urinary tract infection with bacteremia caused by A. viridans in an 87-year-old male nursing home resident is presented.
- The patient exhibited symptoms including fever, dysuria, hematuria, and weakness.
- Urinalysis revealed significant abnormalities, and urine culture confirmed A. viridans growth.
Findings:
- The patient was diagnosed with a urinary tract infection and bacteremia due to A. viridans.
- Laboratory results indicated leukocytosis with neutrophilia.
- Treatment involved a ten-day course of levofloxacin.
Implications:
- This is the first reported clinical case of A. viridans causing a urinary tract infection.
- Further research into the Aerococcus genus is needed to understand its role in human infections.
- Enhanced awareness among clinicians can improve the identification and management of A. viridans infections.
