The bacteria that cause group B strep disease normally live in the intestine, vagina, or rectal areas. Group B strep colonization is not a sexually transmitted disease (STD).. One of every four or five pregnant women carries GBS in the rectum or vagina.
Group A streptococci are bacteria commonly found in the throat and on the skin. The vast majority of GAS infections are relatively mild illnesses, such as strep throat and impetigo.
Bacitracin Test The bacitracin disk is sensitivity test used to differentiate the beta- hemolytic Streptococcus. An overnight culture grown on 5% sheep blood agar incubated 35°C in CO2.
Children often come down with sore throats commonly caused by colds, viruses and, environmental factors such as smoke, dust in the air, and plant allergens.
What causes group B strep? The group B strep bacteria come and go naturally in people’s bodies. If a pregnant woman has the bacteria in her body, she can pass it to her baby during labor and delivery. A group B strep infection happens when a baby is exposed to the bacteria while it’s being born.
Even though health care providers do not widely recognize GBS vaginitis, GBS can cause yellow or green discharge as well as vaginal burning and/or irritation. These symptoms may be mistaken for a yeast infection or bacterial vaginosis.
Group B Streptococcus (group B strep, GBS) are bacteria that come and go naturally in the body. Most of the time the bacteria are not harmful, but they can cause serious illness in people of all ages. In fact, group B strep disease is a common cause of severe infection in newborns.

Counter to guidelines, children with pharyngitis in whom non–group A strep is isolated commonly receive antibiotics. Non–group A streptococcus (NGAS) is detected in close to 12% of throat cultures performed for pharyngitis in school-age children. The detected bacteria likely reflect colonization rather than infection.
Clinicians need to use either a rapid antigen detection test (RADT) or throat culture to confirm group A strep pharyngitis. RADTs have high specificity for group A strep but varying sensitivities when compared to throat culture. Throat culture is the gold standard diagnostic test.
Strep agalactiae has a thick peptidoglycan cell wall, which takes in purple dye when Gram stained – so this is a gram-positive bacteria. It’s non-motile and doesn’t form spores, and also, it’s a facultative anaerobe, meaning that it can survive in both aerobic and anaerobic environments.
Your doctor may perform a rapid antigen test on a swab sample from your throat. This test can detect strep bacteria in minutes by looking for substances (antigens) in the throat. If the test is negative but your doctor still suspects strep, he or she might do a throat culture.
It is unknown (aside from during childbirth) how GBS spreads from person to person. The bacteria is not always present and detectable in the body and may come and go. You may test positive in one pregnancy and negative in another. You cannot give GBS to your partner or your other children.
Many healthy people carry group B strep bacteria in their bodies. You might carry the bacteria in your body for a short time — it can come and go — or you might always have it. Group B strep bacteria aren’t sexually transmitted, and they’re not spread through food or water.
Many disease-causing organisms can survive for only a short time on the surface of the seat, and for an infection to occur, the germs would have to be transferred from the toilet seat to your urethral or genital tract, or through a cut or sore on the buttocks or thighs, which is possible but very unlikely.
Positive Results If your results from the group B strep test come back positive, your pregnancy is labeled “GBS positive.” Treatment will not be prescribed during pregnancy to get rid of group B strep.
If you test positive for group B strep, it doesn’t mean that you’re ill or that your baby will be affected. It simply means you need treatment to prevent an infection in your baby. Talk with your health care provider about how you’ll incorporate your group B strep treatment into your labor plan.
Group B Streptococcus also known as Group B Strep Infection (GBS) is a type of bacterial infection that can be found in a pregnant woman’s vagina or rectum. This bacteria is normally found in the vagina and/or rectum of about 25% of all healthy, adult women.
There are several types. Two of them cause most of the strep infections in people: group A and group B. Group A strep causes: Strep throat – a sore, red throat.
Strep throat is treated using antibiotics. An antibiotic is a type of medicine that kills the bacteria that cause the infection. Antibiotics are often taken as pills or given as a shot. Penicillin and amoxicillin are common antibiotics used to treat strep throat.
Smith, MD, Lubbock, Tex. To be safe, non-group A strep pharyngitis should always be treated. Penicillin is the treatment of choice for either B, C, or G streptococcal species. Non-group A streptococcal pharyngitis has been described with both group C and group G streptococci in some case series.
Group B Streptococcus (GBS) are generally beta hemolytic on blood agar plates (right hand side). The colonies of GBS are gray to whitish-gray surrounded by a weak zone of beta hemolysis of the red blood cells in the culture medium.
These bacteria are spread by direct contact with discharges from the nose and throat of infected people or by contact with infected wounds or sores on the skin. The risk of spreading the infection is highest when a person is ill, such as when people have “strep throat” or an infected wound.
Strep is most commonly found in the mouth and throat. Hence the relatively common condition strep throat. The infection is often accompanied by an extremely sore throat with white patches, difficulty swallowing, and a fever. Meanwhile, staph is a skin infection that is most often the result of surgery or an open wound.
Strep will go away on its own. Your body’s immune system can and will eventually clear the strep bacteria. We mostly give antibiotics to get rid of the infection quicker and avoid the complications of strep, known (cue appropriate dramatic music…) as acute rheumatic fever.
Blood infections: The strep bacteria can also get into your bloodstream, where they don’t normally live. This is called “bacteremia.” If the strep bacteria release toxins in multiple organs, it can create another rare, life-threatening condition called “streptococcal toxic shock syndrome” that can cause organ failure.
Doctors usually treat GBS disease with a type of antibiotic called beta-lactams, which includes penicillin and ampicillin.
Early recognition and treatment is important to cure GBS infection in adults. High doses of antibiotics such as penicillin should be administered and the full course taken. Most GBS infection can be treated successfully, although some people will require all the expertise of intensive care facilities.
On occasion, strep-throat bugs can turn on people who have been under too much stress, or who have an immune system that has been dealing with fights with viruses such as the common cold or the flu. A person may also pick up strep-throat from a person who has been infected.
Fluids may help soothe an irritated throat. Hot fluids, such as tea or soup, may help your throat feel better. Eat soft solids and drink plenty of clear liquids. Flavoured ice pops, ice cream, scrambled eggs, sherbet, and gelatin dessert (such as Jell-O) may also soothe the throat.
Yes, women who test positive for GBS can breastfeed. Rarely, GBS can be spread to babies through breastmilk, but the benefits of breastfeeding are much greater than the risk of spreading GBS. Most of the time, breastfeeding can help lower the risk that of your baby getting GBS later in infancy.
