Sometimes you hear about people comparing "BacterIa-l" to "VirAl" strep.

But real strep is by definition always a bacterial infection.

So I conclude that what the doctor is really sometimes is not "you have viral strep" but rather "you have a viral infection giving you a sore throat".

There is a home detector

This says strep throat only causes about 15% of all cases of sore throats with the vast majority caused by viruses




StrepThroat is caused by the Group A Strep BacterIa - species Streptococcus Pyogenes of the Streptococcus genus.

Group B Strep, or Streptococcus Agalactiae, can cause Perinatal Gbs Disease (an infection passed from the mother to child during birth). Approximately 10% to 30% of pregnant women are colonized with GBS in the vagina or rectum. Since the bacteria can come and go, testing for GBS is needed every pregnancy. Toward the end of a pregnancy, the vagina and rectum are cultured with a swab at a prenatal appointment. Women with GBS are given an antibiotic during labor. GBS is the most common cause of SepSis (infection of the bloodstream) and Mening Itis (infection of the lining and fluid surrounding the brain) and a common cause of Pneumon Ia in newborns. Group B strep bacteria are different from many other types of bacteria that can cause disease. People can be "colonized" with group B strep. This means that they carry the bacteria in their bodies but are not infected and do not become sick. Adults can carry the bacteria in the gastrointestinal tract, genital tract, or urinary tract. About 10% to 30% of pregnant women are colonized with group B strep in the genital tract. Colonization with group B strep is usually harmless. The bacteria can become deadly, though, if something happens that allows them to invade the bloodstream... Infection is fatal in about 20% of infected men and non-pregnant women and about 5% to 15% of infected newborns. Babies who survive can be left with speech, hearing, and vision problems as well as mental retardation... Since 1970, group B strep infection has become the leading bacterial infection causing illness and death in newborns in the United States. GBS is a bacterium that normally lives in the intestinal tracts of many healthy people. A vaginal-rectal area colonized by GBS should not be termed "infected" any more than an intestinal tract colonized by GBS would be. GBS is a problem only when it is present in the genital area of a pregnant woman during labor and delivery.

There are a number of other Lancefield Group-s, including Streptococcus Pneumoniae, which causes Pneumon Ia.
