Streptococcus agalactiae, the Lancefield group B streptococcus (GBS) long recognized as a mammalian pathogen, is an emerging concern with regard to fish. We show that a GBS serotype Ia multilocus sequence type ST-7 isolate from a clinical case of human neonatal meningitis caused disease and death in Nile tilapia (Oreochromis niloticus).
conclusions the determination of serotype and surface proteins of gbs strains distribution would be relevant for the future possible formulation of a gbs vaccine. patients and methods in this cross-sectional study, a total of 100 gbs strains isolated from 237 pregnant and 413 non-pregnant women were investigated for molecular capsular serotypes and surface protein genes using the multiplex p...
Group A Streptococcus (Streptococcus pyogenes), group B Streptococcus (Streptococcus agalactiae) and Streptococcus pneumoniae (pneumococcus) are host-adapted bacterial pathogens among the leading infectious causes of human morbidity and mortality. These microbes and related members of the genus Streptococcus produce an array of toxins that act against human cells or tissues, resulting in impair...
The genus Streptococcus includes a heterogeneous group of different Gram positive species (>30) that are identified on Gram stain by their spherical or ovoid shape and their tendency to grow in pairs and chains. They are nonmotile, non-spore forming, and mostly facultatively anaerobic. Streptococci are a heterogeneous group that includes a variety of species capable of causing a diverse array o...
background: group b streptococcus (gbs) is the major cause of serious life threatening infections in neonates, pregnant women, and other adults with underlying diseases. capsular polysaccharide typing is a significant way for epidemiological studies of gbs, the pathogenesis, and other studies associated with gbs infections including surveillance programs and vaccine development in future. molec...
BACKGROUND Here we report a rare case of lumbar spine epidural abscess and facet joint septic arthritis caused by Streptococcus agalactiae, which had spread to the iliopsoas muscles, leading to urine retention. CASE PRESENTATION A 68-year-old woman with low back pain experienced a sudden onset of bilateral lower limb weakness, it was followed 14 days later by urine retention. At consultation,...
