Antigenic distribution of Streptococcus agalactiae isolates from pregnant women at Garankuwa hospital - South Africa.

Introduction: Streptococcus agalactiae (group B streptococcus; GBS) is globally recognised as one of the leading causes of neonatal sepsis and meningitis. It also causes adverse pregnancy outcomes such as stillbirth and miscarriages. Incidence of invasive disease is increasing in non-pregnant adults with underlying medical conditions (e.

Streptococcus agalactiae colonization and correlation with HIV-1 and HBV seroprevalence in pregnant women from Zimbabwe.

Objective: To estimate the frequency of coinfection of Streptococcus agalactiae or Group B streptococcus (GBS), hepatitis B virus (HBV) and HIV-1 in pregnant women and evaluate any association between them.

Study Design: Three health centres from rural, rural-urban and urban communities were selected and at least 369 pregnant women had samples available for simultaneous analysis of GBS colonization rates, and HIV and HBV seroprevalence rates. Swabs were collected at two different stages in the course of pregnancy and at delivery to isolate GBS.
