Adenitis-cellulitis syndrome: an infrequent presentation of a late onset infection by Streptococcus agalactiae

Abstract

Despite great progress in perinatal S. agalactiae prevention in the 1990s, this bacteria remains a leading cause of serious neonatal infection. The majority of these infections occur during the first week of life, early onset disease. Late onset infections occur in infants aged between 1 week and 3 months, among which the adenitis-cellulitis syndrome is a rare clinical presentation. We report the clinical course of an infant with inguinal adenitis-cellulitis syndrome and bacteraemia caused by S. agalactiae and discuss the clinical features, laboratory findings and outcome of this condition based on a review of the reported cases.
