Association between functional antibody against Group B Streptococcus and maternal and infant colonization in a Gambian cohort

Association between functional antibody against Group B Streptococcus and maternal and infant colonization in a Gambian cohort

BACKGROUND Vertical transmission of Group B Streptococcus (GBS) is a prerequisite for early-onset disease and a consequence of maternal GBS colonization. Disease protection is associated with maternally-derived anti-GBS antibody. Using a novel antibody-mediated C3b/iC3b deposition flow cytometry assay which correlates with opsonic killing we developed a model to assess the impact of maternally-...

Maternal Obesity and Rectovaginal Group B Streptococcus Colonization at Term

OBJECTIVE To test the hypothesis that maternal obesity is an independent risk factor for rectovaginal group B streptococcus (GBS) colonization at term. STUDY DESIGN Retrospective cohort study of consecutive women with singleton term pregnancies admitted in labor at Barnes-Jewish Hospital (2004-2008). Maternal BMI≥30 Kg/m2 (obese) or <30 Kg/m2 (nonobese) defined the two comparison groups. The ...

Association of Group B Streptococcus Colonization and Bovine Exposure: A Prospective Cross-Sectional Cohort Study

BACKGROUND While Group B Streptococcus (GBS) human colonization and infection has long been suspected as originating from cows, several investigators have suggested that ongoing interspecies GBS transmission is unlikely due to genotyping data demonstrating that human and bovine-derived GBS strains represent mostly distinct populations. The possibility of ongoing transmission between humans and ...

The Prevalence of Group B Streptococcus Colonization in Iranian Pregnant Women and Its Subsequent Outcome

cohesion and cohesive devices in a contrastive analysis between ge and esp texts

the present study was an attempt to conduct a contrastive analysis between general english (ge) and english for specific purposes (esp) texts in terms of cohesion and cohesive devices. to this end, thirty texts from different esp and ge textbooks were randomly selected. then they were analyzed manually to find the frequency of cohesive devices. cohesive devices include reference, substitution, ...
