[Staphylococcal pneumonia in a premature neonate: unusual transmission of nosocomial infection]. / Staphylococcie pulmonaire chez un prématuré : infection nosocomiale de transmission inhabituelle.

UNLABELLED: Late onset of neonatal infection could have been transmitted in prenatal period, but it is usually secondary to a postnatal transmission. CASE REPORT: A premature neonate developed staphylococcal pneumonia at 18 days of life. Genomic typing of the strains of Staphylococcus aureus obtained from the patient and from his mother (found in the endocervix culture 48 h before delivery) was identical. These strains were different from those isolated in other neonates colonised by S. aureus in the unit during at that moment. CONCLUSION: The observed case of staphylococcal pneumonia may correspond to a nosocomial infection secondary to a pre- or postnatal transmission of the agent by the mother.
