What is Group B Streptococcus ? GBS is a bacteria that is found in the bowel, genital tract, urinary tract, throat, or respiratory tract of some adults. Many people carry GBS in their bodies but do not become ill.
GBS can cause mild disease in adults, such as urinary tract infections .
GBS can also cause serious infections in adults that include bloodstream infections, pneumonia , skin and soft-tissue infections, and bone and joint infections. Rarely in adults, GBS can cause meningitis .
Who is at highest risk for GBS disease? Most GBS disease occurs in adults with serious medical conditions. These conditions include persons with diabetes, liver disease, and cancer. Others at risk include people with recent trauma and those having certain types of invasive surgical procedures.
How is GBS diagnosed? GBS is diagnosed when the bacteria are grown from cultures of the blood, cerebral spinal fluid or other normally sterile body site. Cultures take a few days to grow.
How is GBS treated? GBS infections are usually treated with penicillin. Sometimes other types of antibiotics are used. Soft tissue and bone infections may require surgery to treat. Treatment often depends on where the bacteria in found in the body.
Is there a vaccine for GBS in adults? Researchers are currently working on developing a vaccine against GBS.

- Vaginal strep B infectionA few months ago I thought I was suffering from a vaginal yeast infection, although it hurt and it wasnt itchy. Well I treated it over and over again with anti fungals the doc gave me but he didnt culture it. Finally he did a culture and said I had a vaginal strep b infection.
- Was the urinary tract infection caused by me having unprotected sex? Should I have it checked out to see if I have an STD as well?
Group B streptococcal vaginal colonization is known to be a cause of neonatal sepsis and is associated with preterm rupture of membranes, and preterm labor and delivery. GBS is found to be the causative organism in UTIs in approximately 5 percent of patients.31,32 Evidence that GBS bacteriuria increases patient risk of preterm rupture of membranes and premature delivery is mixed.33,34 A randomized, controlled trial35 compared the treatment of GBS bacteriuria with penicillin to treatment with placebo. Results indicated a significant reduction in rates of premature rupture of membranes and preterm delivery in the women who received antibiotics. It is unclear if GBS bacteriuria is equivalent to GBS vaginal colonization, but pregnant women with GBS bacteriuria should be treated as GBS carriers and should receive a prophylactic antibiotic during labor.36

Who Gets Group B Streptococcus Disease
Infants may get severe forms of Group B streptococcus disease, including meningitis and bacteremia , transmitted through the birthing process. Adults with factors predisposing them to infections are more likely to have the severe Group B streptococcus disease like bacteremia, pneumonia, and soft tissue or wound infections. Group B streptococcus may also cause urinary tract infections and endometritis after childbirth in otherwise health women.
What Can Complicate A Group B Streptococcal Infection
Pregnant women who have become unwell from a GBS infection are more likely to go into labour before their babys due date, and although rare, their baby is more likely to be stillborn. If you are pregnant and found to have a GBS infection, you will be treated with antibiotics to protect you and your baby.
Babies are more likely to become infected with GBS if they are born before 37 weeks of pregnancy, if their mother has a high temperature during labour or on the day after, or had a prior pregnancy or baby infected with GBS.
In cases of a severe infection, GBS can cause a blood infection or an infection of the membranes surrounding the brain and spinal fluid .

Molecular Characteristic Of Group B Streptococcus
Macrolide Resistance Characterization
Macrolide susceptibility testing was performed by the disk diffusion method. The distinction between cMLSB and iMLSB was made by the cultivation of the examined GBS strain on a growth medium with two discs , erythromycin and clindamycin , placed on the growth medium at a distance of 1216 mm between the edges of the disks. The phenotype was identified by interpreting resistance according to The European Committee on Antimicrobial Susceptibility Testing guidelines 1. Resistance to both antibiotics indicated constitutive phenotype , while inductive phenotype was identified in GBS strains resistant to erythromycin with induced resistance to clindamycin visible as a truncated zone on the side of the erythromycin disk . M phenotype was identified for GBS isolates resistant to erythromycin and sensitive to clindamycin with simultaneous lack of flattening of the growth inhibition zone.
The detection of ermB and mefA/E genes was carried out according to the procedure used by Sutcliffe et al. with specific primers described in detail in our previous paper .

Will Ibe Tested For Group B Strep
Yes, your healthcare provider will test you for GBS late in your pregnancy, around weeks 36 to 37.
Your obstetrician uses a cotton swab to obtain samples of cells from your and rectum. This test doesn’t hurt and takes less than a minute. Then, the sample is sent to a lab where it’s analyzed for group B strep. Most people receive their results within 48 hours. A positive culture result means you’re a GBS carrier, but it doesn’t mean that you or your baby will become sick.
If youre using a midwife, you might be given instructions on how to test yourself at home and submit the swab to a lab.

Group A Streptococcal Infection
| Infectious diseases |
A group A streptococcal infection is an infection with group A streptococcus . Streptococcus pyogenes comprises the vast majority of the Lancefield group A streptococci, and is often used as a synonym for GAS. However, S. dysgalactiae can also be group A.S. pyogenes is a beta-hemolytic species of Gram positive bacteria that is responsible for a wide range of both invasive and noninvasive infections.
Infection of GAS may spread through direct contact with mucus or sores on the skin. GAS infections can cause over 500,000 deaths per year. Despite the emergence of antibiotics as a treatment for group A -hemolytic streptococcus, infection of GAS is an increasing problem, particularly on the continent of Africa.
There are many other types of streptococci , including group B streptococcus and Streptococcus pneumoniae, which cause other types of infections and should not be confused with group A strep. Several virulence factors contribute to the pathogenesis of GAS, such as M protein, hemolysins, and extracellular enzymes.
What Problems Can Gbs Cause In Newborns
Babies with a GBS infection can have one or more of these illnesses:
- Meningitis, an infection of the fluid and lining around the brain
- Pneumonia, a lung infection
Pneumonia and sepsis in newborns can be life-threatening. Most babies who are treated for GBS do fine. But even with treatment, about 1 in 20 babies who have GBS die. Premature babies are more likely to die from GBS than full-term babies . GBS infection may lead to health problems later in life. For example, about 1 in 4 babies who have meningitis caused by GBS develop:
- Hearing problems

Can Group B Streptococcal Infection Be Prevented
GBS infection cannot be prevented entirely, but you can reduce the risk of passing an infection to your baby during birth by receiving antibiotics shortly before. Pregnant women should be tested for GBS before they go into labour so they can receive the antibiotics in hospital.
The antibiotics are delivered from an intravenous drip through a vein in your arm or hand. This way, the medicine travels through your body to your baby before they are born, helping to prevent infection in the first few days of life. The antibiotics should be given at least 4 hours before your baby is born.
If your baby is born by caesarean section , whether planned or unplanned, you do not need antibiotics for GBS. You may be offered other antibiotics as part of the routine care after surgery.
If Your Baby Gets Gbs Do Signs Of Infection Or Other Problems Show Up Right After Birth
Not always. It depends on the kind of GBS infection your baby has. There are two kinds of GBS infections:

Diagnosis And Treatment For Group B Streptococcal Infection
GBS infection is diagnosed from specimens collected from blood, urine or spinal fluid. Vaginal swabs may be collected from pregnant women to determine if they are asymptomatic carriers of these bacteria. The principal form of treatment for GBS is intravenous antibiotics, usually given in hospital. If the bacteria are found in a pregnant woman, intravenous antibiotics are given during the labour.
What Tests Do Health Care Professionals Use To Diagnose Group B Strep Infection
In newborns and in adults, isolation of the GBS bacteria is necessary for a definitive diagnosis. Laboratory studies that isolate the organism from certain body fluids, such as blood, cerebrospinal fluid , and urine, help establish the diagnosis. For screening of pregnant women, a health care professional will obtain a swab of a womans vaginal and rectal area to screen for GBS infection at 35-37 weeks of gestation. Test results can take a few days. A lumbar puncture may need to be performed when meningitis is suspected. A health care professional may order imaging studies such as a chest X-ray to evaluate whether pneumonia is present.

Overall attention for this chapters
In addition to representing a major infection risk for neonates and pregnant women GBS is also a prominent pathogen of the elderly, immunocompromised, and individuals with diabetes and malignancies. These populations are particularly at risk for invasive GBS infection . The manifestations of GBS infection in these populations are highly varied however, some of the most common clinical presentations include skin and soft tissue infections, bacteraemia, pneumonia, arthritis, UTI, and endocarditis . The case fatality rate for GBS infection in elderly adults was estimated to be approximately 15% in the United States between 2001 and 2005 . Importantly, there is no vaccine currently available to prevent GBS disease in neonates or adults despite a substantial research effort in identifying potential immunogens as vaccine candidates in immunization strategies .
Detection And Identification Of Gbs
The majority of GBS infections can be diagnosed through routine laboratory testing of clinical samples such as blood, cerebrospinal fluid, or aspirates from sites of local suppuration. In the majority of cases isolates are rapidly identified by typical colony morphology on agar medium such as tryptic soy agar-5% sheep blood, and are tested for catalase, which streptococci do not express. Isolates are grouped into the Lancefield B group using commercial typing antisera for latex agglutination assays. GBS antigens can occasionally be detected in blood, cerebrospinal fluid, and urine but are not routinely tested for in any diagnostic assays. A Gram stain of a clinical specimen can be useful in the detection of infection but is not specific and therefore not definitive for identification. Polymerase chain reaction and optical immunoassay may, on the other hand, provide rapid and specific results for the detection of GBS infection however, optimization and validation of these assays to ensure sensitivity and specificity has limited their widespread application in the clinical laboratory .

What Are Possible Complications Of Group B Strep In A Baby
In some pregnant women, GBS infection may cause chorioamnionitis. This is infection of the amniotic fluid, sac, and placenta. It can also cause a postpartum infection . Urinary tract infections caused by GBS can lead to preterm labor and birth. Pregnant women with GBS are more likely to need a cesarean delivery. They are also more likely to have heavy bleeding after delivery.
Group B strep is the most common cause of serious infections in newborns. GBS infection can lead to meningitis, pneumonia, or sepsis. Meningitis is more common in a baby who has a GBS infection happen a week to several months after birth.
Older Children And Adults
Children and adults who have a chronic illness that can lower their immune system or who take medication that lowers their ability to fight infections are at risk. In addition, people who have invasive procedures, such as inserting a urinary catheter, are also at risk. As people get older, they do become more susceptible to GBS.
