NMR characterisation of group b streptococcus capsular polysaccharide repeating units
Group B Streptococcus (Streptococcus agalactiae) is a Gram-positive β-haemolytic bacterium and the leading cause of neonatal mortality by sepsis, pneumonia and meningitis. To date, ten serotypes of Group B Streptococcus (GBS) have been recognised (Ia, Ib, II - IX), each identified and …

Evaluating protein-protein interactions of CpsA, a virulence factor in Group B Streptococcus
Streptococcus agalactiae, Group B Streptococcus (GBS), is an important human pathogen, causing life-threatening sepsis and meningitis in newborns. The virulence of GBS in part can be attributed to its ability to produce a polysaccharide capsule. CpsA has been recognized as an integral part of …

Macrolide and lincosamide resistance patterns in invasive and colonizing group B streptococcus isolated in Belgium
… of erythromycin and clindamycin resistance among group B Streptococcus (GBS) have been reported worldwilde. Therefore phenotypical and molecular surveillance of macrolides and lincosamides resistance patterns in Belgium has been conducted. Antimicrobial susceptilities to erythromycin and …

The adherence to group b streptococcus screening guidelines amongst pregnant women in Western Australia – A quantitative descriptive analysis
Colonisation with Group B Streptococci (GBS) is a major risk factor for neonatal infection acquired via vertical transmission during pregnancy, labour, or birth, potentially resulting in significant morbidity and mortality. Universal screening at 35 – 37 weeks gestation for maternal GBS …

Invasive Group B Streptococcal disease in newborns at Groote Schuur Hospital
Background. Group B Streptococcal disease is an important cause of morbidity and mortality in newborns globally, and is more common in Sub-Saharan Africa and South Africa. There are few studies reporting on the burden of invasive Group B Streptococcus disease (iGBS) in newborns in South Africa, …

Neonatal Sepsis And Antibiotic Sensitivity Patterns At A South African Tertiary Nursery – Evolution Over A 15 Year Period
… pneumoniae (32.4% of invasive organisms), Group B streptococcus (16.2%) and Acinetobacter (13.5%). Twenty-nine blood cultures were considered contaminated (5.6% of cultures) of which 1.7% were CONS. The gram-negative organisms showed an increasing resistance to penicillin, ampicillin and …

Roles of Group B Streptococcal membrane proteins in virulence and protection
Group B Streptococcus (GBS) asymptomatically colonizes the rectovaginal tract in up to 20% of women worldwide. During pregnancy, GBS is a leading cause of invasive infections associated with adverse pregnancy outcomes including preterm births, neonatal infections, and stillbirths. In addition to …

Process simulation as a decision support tool for biopharmaceutical process development in a South African context
In 2010 the incidence of neo-natal Group B Streptococcus (GBS) disease in South Africa was 3 per 1000 live births, more than twice the global average of 1.21 per 1000 live births. A recent life cycle impact assessment showed that a new vaccine against GBS disease in South Africa could have a …
