Habitual, repeated, rapid contraction of certain muscles, resulting in stereotyped individualized actions that can be voluntarily suppressed for only brief periods. They often involve the face, vocal cords, neck, and less often the extremities. Examples include repetitive throat clearing, vocalizations, sniffing, pursing the lips, and excessive blinking. Tics tend to be aggravated by emotional stress. When frequent they may interfere with speech and INTERPERSONAL RELATIONS. Conditions which feature frequent and prominent tics as a primary manifestation of disease are referred to as TIC DISORDERS. (From Adams et al., Principles of Neurology, 6th ed, pp109-10)
Inflammation of the throat (PHARYNX).

A neuropsychological disorder related to alterations in DOPAMINE metabolism and neurotransmission involving frontal-subcortical neuronal circuits. Both multiple motor and one or more vocal tics need to be present with TICS occurring many times a day, nearly daily, over a period of more than one year. The onset is before age 18 and the disturbance is not due to direct physiological effects of a substance or a another medical condition. The disturbance causes marked distress or significant impairment in social, occupational, or other important areas of functioning. (From DSM-IV, 1994; Neurol Clin 1997 May;15(2):357-79)

Clindamycin plus gentamicin as expectant therapy for presumed mixed infections. (1/3842)

The prevalence of obligate anaerobes was studied prospectively in 60 patients with severe sepsis of intra-abdominal, soft tissue, female genital or oropulmonary origin. In addition, the efficacy of clindamycin (for anaerobes) plus gentamicin (for aerobic bacteria, especially coliforms) as initial empiric therapy in these patients was evaluated. Among 54 patients with cultural proof of infection, anaerobic pathogens were recovered from 52%. Nineteen patients had bacteremia; Bacteroides fragilis and Klebsiella pneumoniae were the most prevalent pathogens, being isolated in five patients each. Infection was eradicated in 56 of the 60 patients (93%). Mortality related to sepsis was 7% in the entire group, 16% in patients with bacteremia and 2% in patients without bacteremia. Eighty-five percent of aerobic isolates tested were susceptible in vitro to either gentamicin or clindamycin; 97% of anaerobic isolates were inhibited by 5 mug/ml of clindamycin.  (+info)

GM-CSF-deficient mice are susceptible to pulmonary group B streptococcal infection. (2/3842)

Granulocyte-macrophage colony-stimulating factor (GM-CSF) gene-targeted mice (GM-/-) cleared group B streptococcus (GBS) from the lungs more slowly than wild-type mice. Expression of GM-CSF in the respiratory epithelium of GM-/- mice improved bacterial clearance to levels greater than that in wild-type GM+/+ mice. Acute aerosolization of GM-CSF to GM+/+ mice significantly enhanced clearance of GBS at 24 hours. GBS infection was associated with increased neutrophilic infiltration in lungs of GM-/- mice, while macrophage infiltrates predominated in wild-type mice, suggesting an abnormality in macrophage clearance of bacteria in the absence of GM-CSF. While phagocytosis of GBS was unaltered, production of superoxide radicals and hydrogen peroxide was markedly deficient in macrophages from GM-/- mice. Lipid peroxidation, assessed by measuring the isoprostane 8-iso-PGF2alpha, was decreased in the lungs of GM-/- mice. GM-CSF plays an important role in GBS clearance in vivo, mediated in part by its role in enhancing superoxide and hydrogen peroxide production and bacterial killing by alveolar macrophages.  (+info)

A community outbreak of invasive and non-invasive group A beta-haemolytic streptococcal disease in a town in South Wales. (3/3842)

An increase in the incidence of invasive and non-invasive infections caused by group A beta-haemolytic streptococci (GAS) was noted in and around the town of Glynneath (population approx. 4000) in West Glamorgan, South Wales between 1 January and 30 June 1995. A total of 133 cases was ascertained with 127 (96%) occurring between 1 March and 30 June 1995. Six patients had invasive disease (one died) and all presented at the peak of the outbreak. There were 127 non-invasive cases of whom 7 were hospitalized. The outbreak was investigated to determine its extent and whether it was caused by a single M-serotype of GAS. Serotyping showed that 13 different M-serotypes were involved with the M1 serotype predominating. The overall incidence of GAS invasive disease in West Glamorgan (population 365,000) increased sevenfold from a crude incidence of 0.5/10(5) per year in 1994 to 3.5/10(5) per year in 1995, but fell back to 0.75/10(5) per year in 1996. Eighty-two (80%) out of 102 individuals affected by GAS replied to a health questionnaire; sore throat was the commonest symptom reported (97%). Thirty-nine of these index cases identified at least one other member of their household who had experienced similar symptoms. The interval between the onset of illness in members of a single household was 0-83 days with a mean of 22 days. The mean duration of illness was 13.5 days and 61% of patients were treated with penicillin V for a mean duration of 9.3 days. Twenty-one per cent of GAS isolates were erythromycin-resistant and the M4 and M6 serotypes were especially resistant to erythromycin (87.5 and 100% resistance, respectively). Penicillin V failed to eradicate GAS from the throats of 25% of assessable patients. In this community, an outbreak of non-invasive disease caused by GAS was linked in time and place with an outbreak of serious invasive disease.  (+info)

Purification and properties of bacteriolytic enzymes from Bacillus licheniformis YS-1005 against Streptococcus mutans. (4/3842)

To find a novel lytic enzyme against cariogenic Streptococci, strains showing strong lytic activity have been screened from soil using Streptococcus mutans. A strain identified as Bacillus licheniformis secreted two kinds of lytic enzymes, which were purified by methanol precipitation, CM-cellulose chromatography, gel filtration, and hydroxyapatite chromatography. The molecular weights of these two enzymes, L27 and L45, were 27,000 and 45,000, respectively. Optimum pH and temperature of both enzymes for lytic activity were pH 8 and 37 degrees C. L27 and L45 digest the peptide linkage between L-Ala and D-Glu in peptidoglycan of Streptococcus mutans. The lytic activity was highly specific for Streptococcus mutans, suggesting their potential use as a dental care product.  (+info)

Increased activity of 16-membered lactone ring macrolides against erythromycin-resistant Streptococcus pyogenes and Streptococcus pneumoniae: characterization of South African isolates. (5/3842)

The susceptibility of 40 erythromycin-resistant isolates of Streptococcus pyogenes and 40 multiply-resistant isolates of Streptococcus pneumoniae to six macrolide antibiotics, representing 14-, 15- and 16-membered lactone ring structures, was tested. The genetic basis for macrolide resistance in the strains was also determined. Both erm and mef determinants were encountered in the 36 S. pneumoniae isolates tested, but only mef in the five S. pyogenes isolates tested. All isolates showed cross-resistance among the 14-membered macrolides erythromycin, clarithromycin and roxithromycin and the 15-membered macrolide, azithromycin. However, the erythromycin-resistant S. pyogenes isolates retained full susceptibility to spiramycin and josamycin (16-membered agents). These latter two antibiotics were also more active than the other macrolides against erythromycin-resistant S. pneumoniae isolates, especially josamycin which was 8-64 times more active than erythromycin; spiramycin was only two to eight times more active than erythromycin.  (+info)

Epidemiology and prevention of group A streptococcal infections: acute respiratory tract infections, skin infections, and their sequelae at the close of the twentieth century. (6/3842)

Infections of the upper respiratory tract and skin due to group A Streptococcus are common, and the organism is highly transmissible. In industrialized countries and to some extent in developing countries, control efforts continue to emphasize that group A streptococcal pharyngitis should be properly diagnosed and appropriately treated. In developing countries and in indigenous populations where the burden of group A streptococcal diseases appears greatest, the epidemiology is less completely defined and may differ from that in industrialized countries. There is a need for accurately collected epidemiological data from developing countries, which may also further clarify the pathogenesis of group A streptococcal infections and their sequelae. While proper treatment of group A streptococcal pharyngitis continues to be essential in all populations, it may be appropriate in developing countries to consider additional strategies to reduce rates of pyoderma.  (+info)

Interaction between group A streptococci and the plasmin(ogen) system promotes virulence in a mouse skin infection model. (7/3842)

Group A streptococci are capable of acquiring a surface-associated, unregulatable plasmin-like enzymatic activity when incubated in human plasma. The effect of this enzymatic activity on virulence of group A isolate CS101 was examined in a mouse skin infection model. Initial studies demonstrated enhanced virulence for bacteria preincubated in human plasma but not in plasminogen-depleted plasma. A direct correlation between surface-associated enzymatic activity and virulence was not observed; however, an association between virulence and the assembly of a surface-associated plasminogen activator that could activate mouse plasminogen was noted. This activity enhanced virulence in wild type but not in plg-/- plasminogen-deficient mice. These results support the hypothesis that acquisition of a surface-associated plasmin(ogen)-dependent enzymatic activity can contribute to the virulence of group A streptococcal invasive infections.  (+info)

Ultrastructure of surface components of Streptococcus gallolytics (S. bovis) strains of differing virulence isolated from pigeons. (8/3842)

Virulence of Streptococcus gallolyticus (S. bovis) strains isolated from pigeons is associated with the presence of the extracellular proteins A, T1, T2 and T3. Based on the presence or absence of these proteins, six supernatant-phenotypes are distinguished. Experimental infection studies have indicated that strains belonging to the A-T1, A+T1, A+T2 and A+T3 groups are highly virulent for pigeons, strains belonging to the A-T3 groups are moderately virulent and A-T2 strains are of low virulence. In this study the surface structure of 15 pigeon S. gallolyticus strains representing high, moderate and low virulence supernatant-phenotypes was examined by electron microscopy. The presence of capsular material was determined by transmission electron microscopy after polycationic ferritin labelling and immunostabilization. Capsules from cells labelled with polycationic ferritin were usually thicker than those from cells exposed to antiserum. The capsule of the virulent strains had a regular, continuous appearance whilst irregularity of the capsule was a characteristic of the low virulence A-T2 strains. Negative staining revealed the presence of fimbriae in all strains belonging to the high virulence A-T1, A+T1, A+T2 and A+T3 supernatant groups and in one strain of the moderately virulent A-T3 group. The fimbriae were thin, flexible structures with a diameter of approximately 3-4 nm and a length of up to 700 nm. Fimbriae as described above were absent in two other A-T3 strains examined and in the low virulence A-T2 strains. Results from this study indicate that morphological differences in surface structure exist among virulent and low virulence pigeon S. gallolyticus strains, and that the capsule and/or fimbriae are possibly involved in virulence.  (+info)

Beta hemolytic streptococci, particulary group A, are the most frequently isolated pathogens in cases of pharyngoamigdalitis. Other beta hemolytic streptococci also produce this pathology. An increase of positive cultures for group A streptococci was detected during 2004 in relation to previous years. The aim of this study was to determine the isolation rates of beta hemolytic streptococci groups A, C and G during a period of 5 years. Pharyngeal exudates were obtained from children (aged 6 months to 18 years) and adults. Swabs were cultured on Columbia agar plates containing 5% sheep blood. Lancefield grouping was performed using a latex immunoagglutination test. Group A beta hemolytic streptococci were isolated significantly more frequently from pediatric population than from adults. Groups A, C and G beta hemolytic streptococci were isolated significantly more frequently during 2004 than in previous years. Group G beta hemolytic was more prevalent in adult population than in patients less than 18

A group A streptococcal infection is an infection with group A streptococcus (GAS). 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 >500,000 deaths per year. Despite the emergence of antibiotics as a treatment for group A β-hemolytic streptococcus, infection of GAS is an increasing problem, particularly on the continent of Africa. There are many other types of streptococci (species of Streptococcus), including group B streptococcus (Streptococcus agalactiae) and Streptococcus pneumoniae, which cause other types of infections and should not be confused with group A strep. Several virulence factors contribute to the ...

There is a health condition recognized in the biomedical field for autism and related disorders called PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections). This is a condition caused by an immune reaction triggered by the presence of Group A Beta-Hemolytic Streptococcal infection. Various strep bacteria produce toxins as part of their infectious nature. The immune system responds in an attempt to neutralize and eradicate the toxins. However, this immune-toxin (aka: antibody-antigen complex) reaction creates immune complexes which are deposited in various tissues of the body. If these immune complexes land in the kidneys there is an immune reaction called post-streptococcal glomerulonephritis, in the heart it is called rheumatic fever, and in the brain PANDAS can ensue.. This autoimmune reaction (self-directed immune reaction to body tissue) in PANDAS is directed to the Basal Ganglia area in the brain. This area has been associated with disorders such ...

Bacteria carry substances on their surface called antigens. When antigens come into contact with the right kinds of cells in the body an immune reaction is caused. This reaction is often the symptoms of sickness that a patient feels.. In order for the body to fight off the attack of antigens, it creates substances called antibodies. Antibodies counter the action of antigens and make the bacteria harmless. However, the immune system must learn how to make the right antibodies for the right antigens. Sometimes the body creates antibodies that confuse normal tissues as foreign and attack them. This is called an autoimmune reaction and sometimes occurs when the body is exposed to certain bacteria.. One bacteria known for causing autoimmune reactions is Group A beta-hemolytic Streptococcus (GABHS). This bacteria often causes throat infections commonly known as strep throat. Some researchers believe that the autoimmune reaction associated with strep throat infections may cause neuropsychiatric ...
The rate of invasive group A streptococcus infections was highest among those in their 30s and 40s (14.9/100,000 for both), followed closely by those in their 50s (14.8/100,000). The rates among these three age groups were significantly higher than rates among those under the age of 20 years.

We further analysed SIC and DRS seroprevalence among CKD and ESRD cohorts. The results revealed that sera from 19% of CKD patients (n=100) and 35.7% of ESRD patients (n=70) reacted with SIC antigen. Thus, relative to the healthy controls significantly high proportion of CKD and ESRD patients are SIC antibody-positive (chi-square p=0.03 and ,0.001 respectively) (Figure 1). Antibody positivity to SIC seems to predict increased predisposition for both CKD and ESRD, the OR being 3.05 (95% CI 1.08, 8.61; p=0.04) and 7.22 (95% CI 2.57, 20.28; p,0.001) respectively relative to the healthy group. After adjustment for age and sex the ORs showed a similar although somewhat reduced effect: 2.33 (95% CI 0.75, 7.22; p=0.14) and 3.95 (95% CI 2.16, 21.24; p,0.001) respectively. By contrast, seropositivity to DRS in CKD or ESRD was not significantly different to that in the healthy group whether adjusted for age and sex or not (p,0.3 in all cases).. There was no evidence in this study that SIC seropositivity ...
The more we know about each step in the bodys immune response to bacterial infections, the better equipped we are to design more personalized, targeted therapies for autoimmune diseases - therapies that are effective, but minimize risk of infection, said senior author Victor Nizet, MD, professor of pediatrics and pharmacy at UC San Diego School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences.. IL-1beta is a molecule that stimulates an immune response, calling white blood cells to the site of an infection so they can engulf and clear away invading pathogens. The body first produces the molecule in a longer, inactive form that must be cleaved to be activated. The scientific community long believed that only the body itself could cleave and activate IL-1beta, by employing a cellular structure known as the inflammasome. But in experiments using cell cultures and mouse models of infection, Nizet and team found that SpeB, an enzyme secreted by strep bacteria, also cleaves and ...
Project personnel communicated at least monthly with contacts in all microbiology laboratories serving acute care hospitals in their area to identify cases. Standardized case report forms that include information on demographic characteristics, clinical syndrome, and outcome of illness were completed for each identified case. Strains were typed by the emm system at CDC. Regular laboratory audits assess completeness of active surveillance and detect additional cases.. All rates of invasive group A Streptococcal disease were calculated using U.S. Bureau of the Census postcensal population estimates for 1997. For national projections of cases, race- and age-specific rates of disease were applied from the aggregate surveillance area to the age and racial distribution of the 1997 U. S. population. Cases with unknown race were distributed by site based on reported race distribution for known cases within the seven age categories.. ...
My strep test came back negative today, hooray! But in a way it sucks because I still feel like crap, and now I just have a mystery illness. Last night I was hoping to end my 2 night streak of middle of the night drench fests but I was let down by going 3 for 3, and adding in an extra bonus round last night (woo 2 in one night), bringing my total up to 4 drench fests. ...
The culture grew beta hemolytic streptococcus. I know it is normal to have strep on the skin in humans and assume it is the same for dogs. My theory still is the sweater/breaking out of the crate caused the break in the skin which allowed it to become infected as his immune system is so suppressed. The vets say vasculitis. Who knows, he had some strange symptoms before he even wore the sweater so I just dont know ...

Awareness of Primary Care Physicians about Pregnancy Screening of Group B Streptococcus Infection at Prince Sultan Military Medical City, Riyadh, Saudi Arabia
Background: Group B Streptococcus (GBS) is a leading cause of morbidity and mortality in infants in both developed and developing countries. To our knowledge, only a few studies have been reported the clinical features, treatment and outcomes of the GBS disease in China. The severity of neonatal GBS disease in China remains unclear. Population-based surveillance in China is therefore required. Methods: We retrospectively collected data of ,3 months old infants with culture-positive GBS in sterile samples from three large urban tertiary hospitals in South China from Jan 2011 to Dec 2014. The GBS isolates and their antibiotic susceptibility were routinely identified in clinical laboratories in participating hospitals. Serotyping and multi-locus sequence typing (MLST) were also conducted for further analysis of the neonatal GBS disease. Results: Total 70 cases of culture-confirmed invasive GBS infection were identified from 127,206 live births born in studying hospitals, giving an overall incidence ...
Early-onset group B streptococcal sepsis (EOGBS) has been the leading cause of death attributable to infection in newborn infants for nearly 3 decades,1 with ,6000 cases a year in the United States.2 The attack rate has not changed over the past 20 years, but the case-fatality rate has declined from ∼50% to between 10% and 15%.3-5 Long-term morbidity among survivors, particularly neurodevelopmental disabilities in those with meningitis, remain distressingly common.6-9 EOGBS disease may be rapidly progressive and many infants (especially at term) do not exhibit clinical signs of infection initially5; therefore, empirical therapy is often initiated because of clinical risk or minimal signs of disease and continued until infection has been excluded by laboratory studies and a period of observation. This aggressive approach has been associated with improved outcomes for infants with this disease,10 ,11 but also may lead to acute-care hospitalization and treatment of ,100 000 newborn infants yearly ...

At the Royal Womens Hospital, Melbourne over an 8-year period (1981-1988) all public antenatal patients were screened at 32 weeks gestation for group B streptococcus (GBS). In a total of 30,197 livebirths there were no early onset neonatal GBS infections in infants of treated asymptomatic carrier mothers. By contrast there were 27 infections with 8 deaths in an unscreened control group of private patients (total livebirths 26,915). It is recommended that GBS screening occur antenatally at 28 weeks and that intrapartum chemoprophylaxis be offered at least to those carriers with obstetric risk factors.

Introduction: Group B Streptococcus (GBS) infection is the most important cause of neonatal infection in developed and developing countries. UK Nation..
Group B Streptococcus (GBS) is a normal bacterium which can be found in 20- 30% of adults in the UK, usually without any symptoms or side-effects. Its most commonly found in our normal gut flora and is also often found in the vagina of adult women.. GBS can occasionally cause infection, most commonly in newborn babies but also sometimes in women during pregnancy or after birth.. GBS is a recognised cause of preterm delivery, maternal infections, stillbirths and late miscarriages. Preterm babies are known to be at particular risk of GBS infection as their immune systems are not as well developed as those of full-term babies.. Overall, without preventative medicine, GBS infections affect an estimated 1 in every 1,000 babies born in the UK.. ...

Sweeping or stripping of the membranes (in this paper referred to as membrane sweeping) is a widely utilized technique to hasten delivery for women at 37+ weeks gestation. The process of membrane sweeping probably causes release of prostaglandins from the decidua and the cervix. The efficacy of membrane sweeping is well studied, and has been shown to increase the number of patients in labor within 72 hours, reduce the frequency of pregnancy continuing beyond 41 or 42 weeks, and reduce the frequency of formal induction of labor. Thus, it is a safe and practical option for women who wish to avoid inductions of labor or postterm pregnancies.. Group B streptococcus (GBS; streptococcus agalactiae) is a gram positive coccus that frequently colonizes the human genital tract. In pregnant women, GBS can cause urinary tract infections, chorioamnionitis, and postpartum endometritis. Newborn infants can also acquire GBS infection during passage through the vagina. Early onset GBS disease in the newborn ...
A study was carried out to determine the frequency of anal cultures positive for group A beta-hemolytic streptococci in children with acute pharyngitis whose throat cultures were positive for group A beta-hemolytic streptococci. Only 6% of the patients screened had positive anal cultures and none of these children had a history of recurrent streptococcal pharyngitis. This rate does not warrant routinely obtaining anal cultures from children with group A beta-hemolytic streptococcal pharyngitis.. ...
Introduction . Streptococcus dysgalactiae subsp. equisimilis (SDSE) is a β-hemolytic streptococcus that causes severe invasive streptococcal infections, especially in the elderly and people with underlying diseases. SDSE strains are primarily characterized by Lancefield group G or C antigens. Hypothesis/Gap Statement. We have previously reported the prevalence of Lancefield group A SDSE (GA-SDSE) strains in Japan and have analysed the draft genome sequences of these strains. As GA-SDSE is a rare type of SDSE, only one complete genome has been sequenced to date. Aim. The present study is focused on genetic characteristics of GA-SDSE strains. In order to examine molecular characteristics, we also tested growth inhibition of other streptococci by GA-SDSE. Methodology. We determined the complete genome sequences of three GA-SDSE strains by two new generation sequencing systems (short-read and long-read sequencing data). Using the sequences, we also conducted a comparative analysis of GA-SDSE and group C/G

Background.The incidence and severity of invasive group A streptococcal infection demonstrate great variability over time, which at least, in part, seems to be related to group A streptococcal type distribution among the human population.. Methods.An enhanced surveillance study of invasive group A streptococcal infection (746 isolates) was performed in Sweden from April 2002 through December 2004. Noninvasive isolates from either the throat or skin (773 isolates) were collected in parallel for comparison. Clinical and epidemiological data were obtained from 88% of patients with invasive disease and were related to isolate characteristics, including T type, emm sequence type, and the presence of 9 superantigen genes, as well as pulsed-field gel electrophoresis pattern comparisons of selected isolates.. Results.The annual incidence was 3.0 cases per 100,000 population. Among the patients with invasive disease, 11% developed streptococcal toxic shock syndrome, and 9.5% developed necrotizing ...

What is Group B Streptococcus (GBS) and what does it mean for me and my baby? Find out how to decrease the risk of GBS sepsis for newborns.
The group B streptococcus is a common cause of neonatal diseases, such as pneumonia, septicemia, and meningitis; but GBS is also known to cause invasive as well as noninvasive infections in adults. However, little is known about the genetic relationship among the isolates, the diversity of virulence, and possible differences in tropism among GBS isolates. We used MLST analysis and screened for the presence of mobile genetic elements among clinical isolates collected in two geographic regions in Sweden during a 10-year time span to investigate the population structure and dynamics among invasive GBS isolates.. By MLST analysis, 158 GBS invasive isolates collected from northern and western parts of Sweden were resolved into 29 STs and grouped into six genetic lineages, including five major clonal complexes and one singleton. The highly clonal structure has also been shown by a number of other methods, such as pulsed-field gel electrophoresis, multilocus enzyme electrophoresis typing, and randomly ...
Group B streptococcus (strep) is a type of bacteria. It can be found in the digestive tract, urinary tract, and genital area of adults. About 1 in 4 pregnant women carry GBS in their rectum or vagina. During pregnancy, the mother can pass the infection to the baby. The fetus can get GBS during pregnancy. Newborns can get it from the mothers genital tract during delivery.

The rapid strep test (RST) is a rapid antigen detection test (RADT) that is widely used in clinics to assist in the diagnosis of bacterial pharyngitis caused by group A streptococci (GAS), sometimes termed strep throat. There are currently several types of rapid strep test in use, each employing a distinct technology. However, they all work by detecting the presence of GAS in the throat of a person by responding to GAS-specific antigens on a throat swab. A rapid strep test may assist a clinician in deciding whether to prescribe an antibiotic to a person with pharyngitis, a common infection of the throat. Viral infections are responsible for the majority of pharyngitis, but a significant proportion (20% to 40% in children and 5% to 15% in adults) is caused by bacterial infection. The symptoms of viral and bacterial infection may be indistinguishable, but only bacterial pharyngitis can be effectively treated by antibiotics. Since the major cause of bacterial pharyngitis is GAS, the presence of ...
Streptococcus agalactiae is the causative bacterium of streptococcosis and causes severe economic losses in wild and cultured fish and cattle, worldwide. In fish, infection can result in septicemia with hemorrhages on the body surface and in the external and internal organs. Streptococcus agalactiae may be isolated from brain, nares, head kidney and eye of infected fish. Streptococcus agalactiae also causes bovine mastitis and the organism can be isolated from milk samples. Streptococcus agalactiae is classified as Lancefields group B Streptococcus (GBS). There are also nine GBS capsular polysaccharide serotypes. Despite the significance of the disease, only limited information is available on the identification and characterization of the S. agalactiae isolates from fish and cattle. In the present study, GBS isolates from fish (n = 36), bottlenose dolphin (n=1) and cattle GBS isolates (n=10) were found to have a number of common phenotypic characteristics of the S. agalactiae reference strains ...
Estimates of disease burden and data on the sources of invasive postpartum group A streptococcus (GAS) infections will help guide public health action. Active, population-based surveillance was conducted in 9 regions from 1995 through 2000. A case of GAS infection was defined as isolation of GAS from a sterile site in a resident of a surveillance area who was pregnant or in the postpartum period. Census and live birth data were used to calculate rates. Eighty-seven cases of postpartum GAS infection (2.2% of 3957 invasive GAS infections) occurred at 3%-8% of hospitals annually. We estimate that 220 cases occurred annually in the United States. Two or more cases were noted during 6 months at 8 hospitals, during 1 year at 13 hospitals, and during 2 years at 16 hospitals. Cases due to identical emm types clustered more frequently than expected by chance. Although postpartum GAS infections are rare, the clustering of infections due to identical strains suggests that some invasive cases may have a ...
Group B Streptococcus, also known as Streptococcus agalactiae, was once considered a pathogen of only domestic animals, causing mastitis in cows. S agalactiae is now best known as a cause of postpartum infection and as the most common cause of neonatal sepsis.
In humans, Streptococcus agalactiae or group B streptococcus (GBS) is a frequent coloniser of the rectovaginal tract, a major cause of neonatal infectious disease and an emerging cause of disease in non-pregnant adults. In addition, Streptococcus agalactiae causes invasive disease in fish, compromising food security and posing a zoonotic hazard. We studied the molecular epidemiology of S. agalactiae in fish and other aquatic species to assess potential for pathogen transmission between aquatic species and humans. Isolates from fish (n = 26), seals (n = 6), a dolphin and a frog were characterized by pulsed-field gel electrophoresis, multilocus sequence typing and standardized 3-set genotyping, i.e. molecular serotyping and profiling of surface protein genes and mobile genetic elements. Four subpopulations of S. agalactiae were identified among aquatic isolates. Sequence type (ST) 283 serotype III-4 and its novel single locus variant ST491 were detected in fish from Southeast Asia and shared a 3-set
Group A S. pyogenes (GAS) is the causative agent in a wide range of group A streptococcal infections. These infections may be noninvasive or invasive. The noninvasive infections tend to be more common and less severe. The most common of these infections include streptococcal pharyngitis (strep throat) and impetigo.[9] Scarlet fever is also a noninvasive infection, but has not been as common in recent years.. The invasive infections caused by group A β-hemolytic streptococci tend to be more severe and less common. This occurs when the bacterium is able to infect areas where it is not usually found, such as the blood and the organs.[10] The diseases that may be caused include streptococcal toxic shock syndrome, necrotizing fasciitis, pneumonia, and bacteremia.[9] Globally, GAS has been estimated to cause more than 500,000 deaths every year, making it one of the worlds leading pathogens.[9]. Additional complications may be caused by GAS, namely acute rheumatic fever and acute glomerulonephritis. ...

N2 - Streptococcus agalactiae (group B Streptococcus, GBS) is a leading cause of severe invasive disease in neonate, elderly, and immunocompromised patients worldwide. Despite recent advances in the diagnosis and intrapartum antibiotic prophylaxis (IAP) of GBS infections, it remains one of the most common causes of neonatal morbidity and mortality, causing serious infections. Furthermore, recent studies reported an increasing number of GBS infections in pregnant women and elderly. Although IAP is effective, it has several limitations, including increasing antimicrobial resistance and late GBS infection after negative antenatal screening. Maternal immunization is the most promising and effective countermeasure against GBS infection in neonates. However, no vaccine is available to date, but two types of ...
This study investigated the accuracy of rapid diagnosis of group A β-streptococcal pharyngitis by commercial immunochemical antigen test kits in the setting of recent streptococcal pharyngitis. Specifically, it explored whether the false-positive rate of the rapid test was increased because of presumed antigen persistence. Study used 443 patients who had clinical pharyngitis diagnosed as group A β-hemolytic streptococcus infection in the past 28 days and compared them with 232 control patients who had symptoms of pharyngitis but no recent diagnosis of streptococcal pharyngitis. The aim was narrowly focused to compare the rapid strep test with the culture method used in clinical practice. The study found that the rapid strep test in this setting showed no difference in specificity (0.96 vs. 0.98). Hence, the assertion that rapid antigen testing had higher false-positive rates in those with recent infection was not confirmed. It also found that in patients who had recent streptococcal ...
The genetic relatedness and evolutionary relationships between group B streptococcus (GBS) isolates from humans and those from bovines were investigated by phylogenetic analysis of multilocus sequence typing data. The collection of isolates consisted of 111 GBS isolates from cows with mastitis and a diverse global collection of GBS isolates from patients with invasive disease (n = 83) and carriers (n = 69). Cluster analysis showed that the majority of the bovine isolates (93%) grouped into one phylogenetic cluster. The human isolates showed greater diversity and clustered separately from the bovine population. However, the homogeneous human sequence type 17 (ST-17) complex, known to be significantly associated with invasive neonatal disease, was the only human lineage found to be clustered within the bovine population and was distinct from all the other human lineages. Split decomposition analysis revealed that the human isolate ST-17 complex, the major hyperinvasive neonatal clone, has recently arisen

Neonatal group B streptococcus (GBS) infection can be largely prevented with the use of intrapartum antibiotic prophylaxis. Uncertainty about the optimal therapy prompted the Centers for Disease Control and Prevention to recommend two possible strategies: one based on maternal risk factors and the other using a combination of risk factors and anogenital cultures performed at 35 to 37 weeks of gestation. The latter strategy was proposed to reduce GBS infection in otherwise low-risk situations that would not be targeted by the first strategy. Wendel and associates studied the incidence of GBS disease at a large urban hospital.. They noted that intrapartum treatment based on risk factors and antepartum cultures was difficult without clear documentation of efficacy, but selective treatment based on risk factors alone would miss a substantial number of infections. A new protocol, combining intrapartum risk-factor assessment as well as universal neonatal penicillin prophylaxis in low-risk pregnancies, ...
Guttate psoriasis is characterized by the acute onset of small, 1-10 mm diameter, droplike, erythematous-to-salmon-pink papules, usually with a fine scale, as demonstrated in the images below. Although episodes may recur, especially those due to pharyngeal carriage of streptococci, isolated bouts have commonly been described. The sudden appearance of the papular lesions in response to streptococcal infection could either be the first manifestation of psoriasis in a previously unaffected individual or an acute exacerbation of long-standing plaque psoriasis. Guttate psoriasis is often triggered after a streptococcal throat infection, and so people who are prone to this type of infection may experience repeat bouts of guttate psoriasis. Further information on specific treatments is available from the Psoriasis Association. It is closely associated with preceding streptococcal sore throat or tonsillitis. Although many dermatologists have recommended using antibiotics for guttate psoriasis in ...
A vaccine to protect against diseases resulting from infection with Streptococcus pyogenes is under development. This vaccine utilizes a recombinant fusion protein (SpeAB) comprising of genetically detoxified SpeA, a secreted toxin, and SpeB, a surface bound and secreted cysteine protease. During phase I investigations a lead vaccine formulation was determined by optimization of critical parameters such as buffer, pH, stabilizer, and adjuvant interactions. Potency studies in mice demonstrated significantly greater induction of an antigen-specific IgG immune response to the vaccine than antigen alone. Additionally, the antibodies produced were functional at neutralization of wild type SpeA toxin. These results demonstrate that the SpeAB vaccine developed during the phase I investigation has great potential to provide protection against diseases resulting from infection by Streptococcus pyogenes. For phase II development of the vaccine the overall goal is to complete non-clinical safety studies in ...
Streptococcus suis is an important swine pathogen in nearly all countries with an extensive pig industry. It is associated with meningitis, arthritis, endocarditis, septicaemia, bronchopneumonia and sudden death. Attempts to control the disease are still hampered the lack of effective vaccines and sensitive diagnostic tools. A PCR method which can be used for the detection of virulent strains of serotype 2, which is most prevalent serotype, and serotype 1 was developed. However, serotype 1, 2, 7 and 9 strains are frequently isolated from diseased pigs. In European countries, S suis serotype 2 is the most prevalent type isolated from diseased pigs, followed by serotype 9 and 1. In Japan, capsular serotype 2 was also the most prevalent serotype, followed by capsular serotype 7. Most of S suis isolated from diseased pigs belong to a limited number of capsular serotype, often those between 1 and 9. We investigated the distribution of S suis serotype 1, 2, 7 and 9 from 740 pig lungs at abattoir in Jeolla
ABCs personnel routinely contacted all microbiology laboratories serving acute care hospitals in their area to identify cases. Standardized case report forms that include information on demographic characteristics, clinical syndrome, and outcome of illness were completed for each identified case. From select surveillance areas, whole genome sequencing (WGS) was conducted for all group B Streptococcus isolates, which includes deduction of capsular serotype and minimum inhibitory concentration (MIC) predictions, including PBP2x typing to detect decreased beta lactam susceptibility. A strategic subset of isolates was targeted for conventional MIC determination. Regular laboratory audits assessed completeness of active surveillance and detected additional cases.. Rates of early‑onset and late‑onset group B streptococcal disease were calculated using live birth estimates for 2018. All other rates were calculated using population estimates for 2018 from the bridged-race vintage 2018 postcensal ...
Clinical and pathogenic aspects of Group B streptococci (GBS), as a major pathogen responsible of invasive disease in newborn infants, were investigated.. Cases of neonatal septicaemia during 1981-1994 were studied at Orebro Medical Centre Hospital. 132 children ful1filled laboratory and clinical criteria for neonatal septicaemia. The annual incidence increased significantly, from 2.3 cases during the first 7-year period to 3.3 per 1000 live births during the second 7-year period. The increase in incidence between the two 7- year periods was almost entirely due to an increase in Staphylococcus aureus ( from 9 to 32, p,O.Ol) and coagulase-negative staphylococci (CoNS) (from 7 to 20, p,0.05) and mainly affected preterm neonates 48h or more after delivery while GBS infection usually occurred in full-term children during the first 48h of life. An increased resistance among CoNS to methicillin and gentamicin was observed between the first and second 7-year period.. To study the ability of GBS to ...
