Postoperative Chryseobacterium indologenes bloodstream infection caused by contamination of distillate water

Area of Science:

• Medical Microbiology
• Infectious Diseases
• Environmental Health

Background:

• Bloodstream infections pose significant risks, particularly in vulnerable infant populations.
• The identification of Chryseobacterium indologenes as a pathogen requires careful source tracing.
• Hospital-acquired infections necessitate stringent environmental monitoring and control measures.

Observation:

• Chryseobacterium indologenes was identified in blood cultures from a 5-month-old infant presenting with a bloodstream infection.
• Environmental sampling was conducted to identify the source of the infection.
• Molecular typing techniques, specifically arbitrarily primed polymerase chain reaction (AP-PCR), were employed for bacterial identification and source tracking.

Findings:

• The arbitrarily primed polymerase chain reaction (AP-PCR) analysis revealed cross-contamination within commercial distillate water.
• The infant's bloodstream infection was directly linked to this contaminated distillate water.
• The route of infection was associated with medical assistance provided during the infant's hospitalization.

Implications:

• This case underscores the potential for commercially prepared products to harbor and transmit pathogenic bacteria.
• It highlights the critical importance of rigorous quality control and environmental surveillance of medical supplies, including sterile water.
• Implementing enhanced disinfection protocols for medical water sources is crucial to prevent similar nosocomial infections in infants.
