Abstract
Aim. – Group B Streptococcus (GBS) is the germ most often responsible for neonatal infections. Several risk factors are described. The objective of this investigation was to demonstrate the effects of age, sex, and place of birth in neonates GBS infection, including serotype distribution. Method. – A 4 years-long multicentric study was carried out in Constantine and 2 of its suburbs, including 8,711 live neonates. Seven hundred and thirty-three suspected infections were recorded and sorted according to postnatal age (≤ 7 days and > 7 days), sex, and place of birth (related to the mothers’ socioprofessional status). Thirty-one cases of GBS infection were confirmed. Results. – GBS was identified in 53 out of 733 suspected cases of infection (i.e.: 7.2% or 1/14 suspected case). The incidence of early GBS infection was greater than late onset (36 vs 17 out of 53 cases). GBS colonization was not related to age. High socioprofessional status decreased the infection risk significantly in neonates. Conclusion. – This study demonstrates that favorable hygiene and the mother’s high socioprofessional status decrease the risk of neonatal GBS infection
