have had group B streptococcal colonization, bacteriuria, or infection in a previous pregnancy, and have not had a negative test for group B streptococcus by enrichment culture or PCR on a rectovaginal swab sample collected between 35 and 37 weeks' gestation or 3-5 weeks before the anticipated delivery date in the current pregnancy or
The plural term group B streptococci (referring to the serotypes) and the singular term group B streptococcus (referring to the single species) are both commonly used synonymously with S. agalactiae even though S. halichoeri and S. pseudoporcinus are also group B Streptococci.

To reduce neonatal infection, screening of pregnant women for HIV, hepatitis B, and syphilis, is available in the UK and the United States. [37] [38] Treatment with a vaginal antibiotic wash prior to birth does not prevent infection with group B streptococcus bacteria (GBS).
Similarly, group B streptococcus typically denotes Streptococcus agalactiae, although minor beta-hemolytic group B streptococci like S. troglodytidis exist. [15] While most streptococcal illnesses in humans originate from species adapted to humans, such as S. pneumoniae or S. pyogenes , there are zoonotic species capable of causing infections ...
Since the 1990s early-onset sepsis has declined because of screening of group B streptococcus. The cause of early-onset neonatal sepsis are pathogens that contaminate the placenta, vaginal canal, cervix, or amniotic fluid, and these pathogens can affect the baby either in the womb or during labor.
