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

There was a high prevalence of single infections with GBS and HIV-1 but a lower HBV prevalence among pregnant women studied compared to other studies in Zimbabwe. Coinfection with GBS/HIV-1 was more common than GBS/HBV and HBV/HIV-1. Coinfection with HIV-1 and HBV did not differ between GBS colonized and GBS negative women. There was no difference in GBS colonization rate between HIV-1 positive and HIV-1 negative pregnant women.
