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. These species test positive as group B, but are not frequently ...

Granada medium is a selective and differential culture medium designed to selectively isolate Streptococcus agalactiae (Group B streptococcus, GBS) and differentiate it from other microorganisms. Granada Medium was developed by Manuel Rosa-Fraile et al. at the Service of Microbiology in the Hospital Virgen de las Nieves in Granada (Spain).
Bacteria of the genus Enterococcus, formerly known as group D streptococci, were classified as members of the genus Streptococcus until 1984 and are included in the original Lancefield grouping. [4] Many—but not all—species of streptococcus are beta-hemolytic .
For this test, the patient will gargle a small amount of salt water and then spit the fluid into a clean cup. This method gives a larger sample than a throat swab and may make the culture more reliable. A culture for Streptococcus pyogenes can take 18–24 hours when grown at 37 degrees Celsius (body temperature). [1]
The CAMP test (Christie–Atkins–Munch-Petersen) is a test to identify group B β-hemolytic streptococci (Streptococcus agalactiae) [1] [2] based on their formation of a substance, CAMP factor, [3] that enlarges the area of hemolysis formed by the β-hemolysin elaborated from Staphylococcus aureus.
In the medical setting, the most important groups are the alpha-hemolytic streptococci S. pneumoniae and Streptococcus viridans groups, and the beta-hemolytic streptococci of Lancefield groups A and B (also known as "group A strep" and "group B strep"). Table: Medically relevant streptococci [10]
