Group B streptococcal haemolysin and pigment, a tale of twins

Group B streptococcus [(GBS or Streptococcus agalactiae)] is a leading cause of neonatal meningitis and septicaemia. Most clinical isolates express simultaneously a β-haemolysin/cytolysin and a red polyenic pigment, two phenotypic traits important for GBS identification in medical microbiology. The genetic determinants encoding the GBS haemolysin and pigment have been elucidated and the molecul...

Group B Streptococcal Sepsis in a Newborn: a Case Report

Newborns’ bacterial infections due to group B Streptococcus (GBS) happen in two forms including early-onset disease or late-onset disease. In this paper, we report a case of early-onset GBS infection in a male infant. A 22-year-old primigravid woman delivers a term normal looking male infant. Nasal flaring, grunting, and poor feeding presented soon after birth. An empiric treatment wit...

Group B Streptococcal Infections.

Group B streptococcal disease remains a prominent cause of infectious morbidity in pregnant women and their infants. This article highlights recent developments that are relevant for obstetricians, perinatologists, and neonatologists caring for patients with group B streptococcal disease. The morbidity of group B streptococcal infections in pregnancy and the proposed association of colonization...

Group B Streptococcal Myocarditis

Bacterial myocarditis is an uncommon form of infectious myocarditis. The definitive diagnosis requires histopathology with evidence of bacterial invasion. We report a case of group B streptococcal myocarditis secondary to septicaemia with complete atrioventricular (AV) block and new left bundle branch block. The histopathology revealed patchy small foci of myocyte necrosis. The necrotic areas c...
