title: Nasal colonization of infants with group B Streptococcus associated with intrauterine pressure transducers.
abstract: The rate of nasal colonization with group B Streptococcus in infants cultured at the time of discharge from the nursery rose significantly during a four-month interval. Investigation of this trend resulted in detection of group B streptococci in the domes of two intrauterine pressure transducers (IPTs). Subsequent routine sterilization of IPT domes after each maternal use was associated with a decline in infant group B streptococcal colonization to the usual endemic rate in the nursery. Retrospective evaluation demonstrated that colonization in infants born to IPT-monitored women had increased significantly during the study interval and that no increase in colonization occurred in infants born to non-IPT-monitored women. From epidemiologic evidence it appears that use of contaminated IPTs during labor was a nosocomial source of group B streptococcal colonization.
