Group B streptococcus, or group B strep, is a common type of bacteria that lives in some adults and children. It is not usually dangerous, but infection with this bacteria may be more serious in babies. If a pregnant woman carries group B strep, the bacteria can sometimes pass to a baby during delivery, which can present problems. Therefore, preventing group B strep infection is important for a healthy delivery. Group B strep infection causes a range of symptoms in both adults and babies. A doctor can diagnose and treat this infection.

Group B Streptococcus (GBS) in Adults: Commonly Asked Questions

Site Logo

Group B streptococcal infection , also known as Group B streptococcal disease or just Group B strep , [1] is the infection caused by the bacterium Streptococcus agalactiae S. GBS infection can cause serious illness and sometimes death, especially in newborns, the elderly, and people with compromised immune systems. It can cause bovine mastitis inflammation of the udder in dairy cows. The species name "agalactiae" meaning "no milk", alludes to this.

Its significance as a human pathogen was first described in , when Fry reported three fatal cases of puerperal infections caused by GBS. As mentioned, S. GBS is characterized by the presence in the cell wall of the group B antigen of the Lancefield classification Lancefield grouping that can be detected directly in intact bacteria using latex agglutination tests.

Haemolytic GBS strains produce an orange-brick-red non isoprenoid polyene pigment ornythinrhamnododecaene granadaene when cultivated on granada medium that allows its straightforward identification.

Additionally GBS colonies can be tentatively identified after their appearance in chromogenic agar media. GBS is found in the gastrointestinal and genitourinary tract of humans and is normal component of the intestinal and vaginal microbiota in some women.

Vaginal or rectal colonization may be intermittent, transitory, or persistent. Though GBS colonization is asymptomatic and, in general, does not cause problems, it can sometimes cause serious illness for the mother and the baby during gestation and after delivery.

GBS infections in the mother can cause chorioamnionitis intra-amniotic infection or severe infection of the placental tissues infrequently, postpartum infections after birth and it had been related with prematurity and fetal death.

In the western world, GBS in the absence of effective prevention measures is the main cause of bacterial infections in newborns, such as sepsis , pneumonia , and meningitis , which can lead to death or long-term after effects. The most common clinical syndromes of GBS-EOD are sepsis without apparent location, pneumonia, and less frequently meningitis. Neonates with meningitis often have an initial clinical presentation identical to presentation in those without meningeal affectation.

An exam of the cerebrospinal fluid is often necessary to rule out meningitis. GBS-EOD is acquired vertically vertical transmission , through exposure of the fetus or the baby to GBS from the vagina of a colonized woman, either in utero because of ascending infection or during birth, after rupture of membranes.

Infants can also be infected during passage through the birth canal, nevertheless, newborns who acquire GBS through this route can only become colonized, and these colonized infants usually do not develop GBS-EOD.

These factors are: [5] [20]. Women who had one of these risk factors but who are not GBS colonized at labour are at low risk for GBS-EOD compared to women who were colonized prenatally, but had none of the aforementioned risk factors. Fatal neonatal infections by GBS are more frequent among premature infants. Prematurity has been reported to be the main risk factor. Each week of decreasing gestation increases the risk by a factor of 1. GBS-LOD is not acquired through vertical transmission during delivery; it can be acquired later from the mother from breast milk or from environmental and community sources.

GBS-LOD commonly shows nonspecific signs, and diagnosis should be made obtaining blood cultures in febrile newborns. Hearing loss and mental impairment can be a long-term consequence of GBS meningitis. Intravenous penicillin or ampicillin given at the onset of labour and then again every four hours until delivery to GBS colonized women have been proven to be very effective at preventing vertical transmission of GBS from mother to baby and GBS-EOD penicillin G, 5 million units IV initial dose, then 3 million units [22] every 4 hours until delivery or ampicillin, 2 g IV initial dose, then 1 g IV every 4 hours until delivery.

Penicillin- allergic women without a history of anaphylaxis angioedema , respiratory distress , or urticaria following administration of a penicillin or a cephalosporin low risk of anaphylaxis could receive cefazolin 2 g IV initial dose, then 1 g IV every 8 hours until delivery instead of penicillin or ampicillin. Antibiotic susceptibility testing of GBS isolates is crucial for appropriate antibiotic selection for IAP in penicillin-allergic women, because resistance to clindamycin, the most common agent used in penicillin-allergic women , is increasing among GBS isolates.

Appropriate methodologies for testing are important, because resistance to clyndamicin antimicrobial resistance can occur in some GBS strains that appear susceptible antibiotic sensitivity in certain susceptibility tests.

For women who are at risk of anaphylaxis after exposure to penicillin, the laboratory requisitions should indicate clearly the presence of penicillin allergy to ensure that the laboratory is aware for the need of testing GBS isolates for clindamycin susceptibility.

If appropriate IAP in GBS colonized women starts at least 2 hours before the delivery, the risk of neonatal infection is also somehow reduced. True penicillin allergy is rare with an estimated frequency of anaphylaxis of one to five episodes per 10, cases of penicillin therapy.

IAPs have been considered to be associated with the emergence of resistant bacterial strains and with an increase in the incidence of early-onset infections caused by other pathogens, mainly Gram-negative bacteria such as Escherichia coli.

Nevertheless, most studies have not found an increased rate of non-GBS early-onset sepsis related to the widespread use of IAP. Other strategies to prevent GBS-EOD have been studied, and chlorhexidine intrapartum vaginal cleansing has been proposed to help preventing GBS-EOD, nevertheless no evidence has been shown for the effectiveness of this approach. Two ways are used to select female candidates to IAP: the culture-based screening approach and the risk-based approach.

The risk-based approach is, in general, less effective than the culture-based approach, [47] because in most cases, GBS-EOD develops among newborns who have been born to mothers without risk factors. IAP is not required for women undergoing planned caesarean section in the absence of labour and with intact membranes, irrespective of the carriage of GBS.

The risk-based strategy is advocated, among other counties, in the United Kingdom, the Netherlands, New Zealand, and Argentina. The issue of cost-effectiveness of both strategies for identifying candidates for IAP is less clear-cut, and some studies have indicated that testing low risk women, plus IAP administered to high-risk women, and to those found to carry GBS is more cost-effective than the current UK practice. Testing pregnant women to detect GBS carriers has also been proposed, and giving IAP to those carrying GBS and to high-risk women, is significantly more cost-effective than the use of the risk-factor approach.

Where insufficient intravenous antibiotics are given before delivery, the baby may be given antibiotics immediately after birth, although evidence is inconclusive as to whether this practice is effective or not. Home births are becoming increasingly popular in the UK.

Recommendations for preventing GBS infections in newborns are the same for home births as for hospital births. Nevertheless, during pregnancy, colonization can be temporary, intermittent, or continual.

Because of that, testing for GBS colonization in pregnant women is recommended by the CDC at 35—37 weeks of gestation. This new recommendation provides a 5-week window for valid culture results that includes births that occur up to a gestational age of at least 41 weeks. The clinical samples recommended for culture of GBS are swabs collected from the lower vagina and rectum through the external anal sphincter. The sample should be collected swabbing the lower vagina vaginal introitus followed by the rectum i.

Cervical, perianal, perirectal, or perineal specimens are not acceptable, and a speculum should not be used for sample collection. Following the recommendations of the CDC, these swabs should be placed into a non-nutritive transport medium. When feasible, specimens should be refrigerated and sent to the laboratory as soon as possible.

However, the recovery of GBS declines over one to four days, especially at elevated temperatures, which can lead to false-negative results. Samples vaginal, rectal, or vaginorectal swabs should be inoculated into a selective enrichment broth, Todd Hewitt broth with selective antibiotics, enrichment culture. This involves growing the samples in an enriched medium to improve the viability of the GBS and simultaneously impairing the growth of other naturally occurring bacteria.

After incubation, the enrichment broth can also be subcultured to granada medium agar where GBS grows as pinkish-red colonies [16] [17] [66] [68] [69] or to chromogenic agars, where GBS grows as coloured colonies. Inoculating directly the vaginal and rectal swabs or the vaginorectal swab in a plate of an appropriate culture medium blood agar, granada medium or chromogenic media is also possible.

However, this method bypassing the selective enrichment broth step can lead to some false-negative results, and this approach should be taken only in addition to, and not instead of, inoculation into selective broth.

However, the implementation of this test seems to be a viable option. At present, culture for GBS using enriched culture medium at 35—37 weeks to define an at-risk group of women appears to be the most cost-effective strategy.

No current culture-based test is both accurate enough and fast enough to be recommended for detecting GBS once labour starts. Plating of swab samples requires time for the bacteria to grow, meaning that this is unsuitable to be used as an intrapartum point-of-care test.

Alternative methods to detect GBS in clinical samples as vaginorectal swabs rapidly have been developed, such are the methods based on nucleic acid amplification tests , such as polymerase chain reaction PCR tests, and DNA hybridization probes. These tests can also be used to detect GBS directly from broth media, after the enrichment step, avoiding the subculture of the incubated enrichment broth to an appropriate agar plate.

Testing women for GBS colonization using vaginal or rectal swabs at 35—37 weeks of gestation and culturing them in an enriched media is not as rapid as a PCR test that would check whether the pregnant woman is carrying GBS at delivery. However, the PCR technology to detect GBS must be improved and simplified to make the method cost-effective and fully useful as a point-of-care test.

These tests still cannot replace antenatal culture for the accurate detection of GBS. Most cases of GBS-EOD occur in term infants born to mothers who screened negative for GBS colonization and in preterm infants born to mothers who were not screened, though some false-negative results observed in the GBS screening tests can be due to the test limitations and to the acquisition of GBS between the time of screening and delivery.

These data show that improvements in specimen collection and processing methods for detecting GBS are still necessary in some settings. False-negative screening test, along with failure to receive IAP in women delivering preterm with unknown GBS colonization status, and the administration of inappropriate IAP agents to penicillin-allergic women account for most missed opportunities for prevention of cases of GBS-EOD.

GBS-EOD infections presented in infants whose mothers had been screened as GBS culture-negative are particularly worrying, and may be caused by incorrect sample collection, delay in processing the samples, incorrect laboratory techniques, recent antibiotic use, or GBS colonization after the screening was carried out.

Very marked variations were observed, the incidence in Scotland was 0. Nevertheless, it may be a serious underestimation of the real incidence of GBS infections in newborns. A plausible explanation of this is that a considerable number of infants with probable GBS-EOD had negative cultures as a result of a previous maternal antibiotic treatment that inhibits the growth of GBS in blood and cerebrospinal fluid cultures, but does not mask clinical symptoms.

Data collected prospectively for neonates that required a septic screen in the first 72 hrs of life in the UK, indicated a combined rate of definite and probable GBS-EOD infection of 3.

In Spain, the incidence of GBS vertical sepsis declined by The mortality rate was 8. In France since , a rapid decrease in the incidence of the neonatal GBS infections has also been reported after widespread use of IAP, from 0.

Since the incidence of neonatal GBS infection has been estimated as 0. Countries reporting no use of IAP had a 2. It has been estimated that GBS infections cause at least The following are estimates of the chances that a baby will be infected with a GBS neonatal infection if no preventive measures are taken and no other risk factors are present: [92]. This guideline clearly stated: "Routine bacteriological screening of all pregnant women for antenatal GBS carriage is not recommended, and vaginal swabs should not be taken during pregnancy unless there is a clinical indication to do so.

Nevertheless, this guideline uses minimum incidence figures from a study undertaken in , [93] so it could not only have underestimated the true incidence of GBS infection, but it could also have underestimated the risks to babies from GBS infection. GBS infection in babies has increased in England, Wales, and Northern Ireland since when the guideline was introduced. In , the RCOG published the findings of their audit to evaluate practice in the UK obstetric units against their recommendations.

They found that, in the 48 cases of GBS during to 0. The most notable change being the clarification of procedure when a woman carrying GBS has PROM and the clarification that oral antibiotics are not recommended in labour against GBS infection in the baby. The review also dealt with a common misconception regarding vaginal cleansing stating that no evidence shows that this procedure can reduce GBS infection in the baby. New evidence and guidance in this field were reviewed by the RCOG in , and it was decided that revision of the guideline would be deferred to a later date and in the meantime the version available on the website will remain valid until replaced.

As a result of the audit, the RCOG have recommended that the national guidelines for preventing GBS infection in newborns should be updated. Immediate induction of labour and IAP should be offered to all women with prelabour rupture of membranes at 37 weeks of gestation or more, to women whose membranes are ruptured more than 18 hours and to those who have fever in labour. Women who are pyrexial in labour should be offered broad-spectrum antibiotics including an antibiotic appropriate for preventing EOD-GBS.

In the UK, it has also been suggested that: "For women known to carry GBS where it is not expected that the intravenous antibiotics can be given for at least 4 hours before delivery, an intramuscular injection of 4. Nevertheless, the NICE guideline "Neonatal infection: antibiotics for prevention and treatment" states: "Intrapartum Antibiotic Prophylaxis should be offered if group B streptococcal colonisation, bacteriuria or infection are detected in the current pregnancy".

This decision was strongly criticized by the charity Group B Strep Support as ignoring both the wishes of the public and the rising incidence rates of GBS infection in the UK. This learning package was developed to raise awareness of GBS amongst health care professionals.

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 bladder infections.

Back to Health A to Z. It's very common — up to 2 in 5 people have it living in their body, usually in the rectum or vagina. It's not routinely tested for, but may be found during tests carried out for another reason, such as a urine test or vaginal swab. Routine testing isn't currently recommended and tests are rarely done on the NHS, but you can pay for one privately. You can find information about getting tested for group B strep on the Group B Strep Support website. If tests find group B strep, or you have had a baby that's been affected by it before, you may need extra care and treatment.

Монитор погас. Когда Сьюзан вернулась в Третий узел, Грег Хейл как ни в чем не бывало тихо сидел за своим терминалом. ГЛАВА 30 Альфонсо XIII оказался небольшим четырехзвездочным отелем, расположенным в некотором отдалении от Пуэрта-де-Хереса и окруженным кованой чугунной оградой и кустами сирени.

Поднявшись по мраморным ступенькам, Дэвид подошел к двери, и она точно по волшебству открылась.

В тот момент Сьюзан поняла, за что уважает Тревора Стратмора. Все эти десять лет, в штиль и в бурю, он вел ее за. Уверенно и неуклонно. Не сбиваясь с курса. Именно эта целеустремленность всегда изумляла, эта неколебимая верность принципам, стране, идеалам.

Он был уверен, что спрятал все следы, и не имел ни малейшего понятия о том, что Сьюзан были известны его действия. Понятно, почему она не хотела верить ни одному его слову. Он почувствовал, как вокруг него выросла стена, и понял, что ему не удастся выпутаться из этой ситуации, по крайней мере своевременно.
