[Candida albicans outbreak in a neonatal intensive care unit]

Area of Science:

• Medical Microbiology
• Infectious Diseases
• Neonatal Care

Background:

• Candida albicans infections can occur in neonates, posing significant health risks.
• Identifying the source and transmission routes of Candida albicans is crucial for outbreak control in neonatal units.

Purpose of the Study:

• To investigate an outbreak of Candida albicans infections in a neonatal unit.
• To determine the transmission dynamics of Candida albicans among neonates and healthcare settings.

Main Methods:

• Microbiologic screening of neonates, caregivers, and environmental surfaces using swabs.
• Culture on Chromagar Candida and SDA media.
• Molecular typing of Candida albicans isolates using Restriction Amplification of Polymorphic DNA (RAPD) analysis.

Main Results:

• Identical strains of Candida albicans were isolated from three neonates, the mother of one neonate, and another colonized newborn.
• The outbreak strain was traced to the congenital infection of the first neonate.
• Candida albicans was not detected in other sampled individuals or environments.

Conclusions:

• The study suggests horizontal transmission of Candida albicans from an initially congenitally infected neonate to others in the unit.
• The findings underscore the importance of recognizing Candida albicans in clinical settings as a potential indicator of nosocomial transmission.
• Vigilance for common Candida species, not just rare ones, is essential for early outbreak detection and management in neonatal intensive care units.
