Outbreak of Pseudomonas aeruginosa infections in a neonatal care unit associated with feeding bottles heaters.

This report describes an outbreak caused by Pseudomonas aeruginosa in a neonatal care unit possibly linked to feeding bottles heaters. Infection control measures were undertaken such as reinforcement of contact isolation precautions, environmental microbiologic sampling, educational sessions on hand hygiene, and use of sterilized water to refill feeding bottles heaters. The sustained eradication of P aeruginosa isolates after implementing control measures on feeding bottles heaters strongly suggests those as the source of the outbreak.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) has become an important hospital-acquired pathogen, with transfer of the organism from a carrier or infected patient to uninfected patients by the hands or clothing of staff as the main mode of transmission.

Methods: Investigation of a cluster of new cases of MRSA resistant to mupirocin and fusidic acid, using epidemiological and microbiological resources.

Results: From September 2010 to February 2012, sixteen patients had at least one culture positive for MRSA resistant to mupirocin and fusidic acid.
