  • Title: Nosocomial Stenotrophomonas maltophilia cross-infection: three cases in newborns.
    Author: Gulcan H, Kuzucu C, Durmaz R.
    Journal: Am J Infect Control; 2004 Oct; 32(6):365-8. PubMed ID: 15454897.
    Abstract:
    BACKGROUND: Increased nosocomial Stenotrophomonas maltophilia infection rates in newborns, especially in recent years, are a significant cause for concern. These cases are the second case group in the literature to have been identified as nosocomial cross-infection with S. maltophilia in neonates. OBJECTIVE: To investigate the clinical, microbiological, and epidemiologic features of the outbreak caused by S. maltophilia in the neonatal intensive care unit within a period of 7 days. METHODS: Three cases with nosocomial S. maltophilia infection considered to be the result of cross-transmission were prospectively analyzed. Arbitrarily primed polymerase chain reaction (AP-PCR) performed with M13 primer and pulsed-field gel electrophoresis (PFGE) of genomic DNA after digestion with XbaI were used to determine clonal relationship among the isolates. Results S. maltophilia was isolated from the blood cultures of all 3 patients. Molecular typing confirmed that the 3 cases were epidemiologically linked. CONCLUSIONS: Opportunistic pathogens such as S. maltophilia can lead to major problems in neonates. Molecular typing is helpful to improve effective control programs for preventing the spread of the infection.
