Streptococcus agalactiae (Group B streptococcus, GBS) is a leading cause of infections in neonates and an emerging pathogen in adults. The Lancefield Group B carbohydrate (GBC) is a peptidoglycan-anchored antigen that defines this species as a Group B Streptococcus. Despite earlier immunological and biochemical characterizations, the function of this abundant glycopolymer has never been address...

The bacterium Streptococcus agalactiae is an etiologic agent in the pathogenesis of endocarditis in humans. FbsA, a fibrinogen-binding protein produced by this pathogen, is considered an important virulence factor. In the present study we provide evidence that S agalactiae clinical isolates bearing FbsA attach to fibrinogen and elicit a fibrinogen-dependent aggregation of platelets. Mutants of ...

Group B Streptococcus (GBS) causes disease in newborns, pregnant women, and adults with underlying medical conditions, but it is also a commensal organism that commonly colonizes the bowel. In this study, the prevalence of colonization was high among 241 women (34%) and 211 men (20%) living in a college dormitory; sexually experienced subjects had twice the colonization rates of sexually inexpe...

The performances of the ESwab and Amies transport media were evaluated for optimal survival of group B streptococcus (GBS) in StrepB carrot broth. ESwab was superior to Amies at all temperatures evaluated but was optimal at 21°C and 24°C, whereas recovery in Amies was significantly decreased at these temperatures.

BACKGROUND Streptococcus agalactiae or group B Streptococcus (GBS) has been recognized as a lethal pathogen in neonates worldwide. S. agalactiae infections also severely affect pregnant women and immunosuppressed adults with substantial attributable morbidity and mortality. However, in Latin America, studies on the epidemiology and behaviour of S. agalactiae infections remain limited. METHODS...

We demonstrate a Fourier pulse-shaper-based differential group delay (DGD) emulator which can be programmed to possess arbitrary user-specified frequency dependent DGD profile. The DGD produced can be up to 400ps range with <1ps accuracy. Generated frequency-dependent DGD profiles are in excellent agreement with numerical simulations.

Streptococcus agalactiae, also referred to as Group B Streptococcus, is a frequent resident of the rectovaginal tract in humans, and a major cause of neonatal infection. The pathogen can also infect adults with underlying disease, particularly the elderly and immunocompromised ones. In addition, S. agalactiae is a known fish pathogen, which compromises food safety and represents a zoonotic haza...

Herein, we report the draft genome sequence of Streptococcus agalactiae ED-NGS-1000, cultivated from a blood sample taken from a preterm neonate blood sepsis patient at the Royal Infirmary, Edinburgh, Scotland, United Kingdom.

Strep throat can be a real pain in the neck, err, throat, and the streptococcus bacteria is to blame. Streptococcus has hundreds of different strains that are organized into group A and group B. Group A strep (GAS), or streptococcus pyogenes, causes strep throat, as well as scarlet fever [2] and impetigo [3]. Group B strep (GBS), or streptococcus agalactiae, causes blood infections, pneumonia, ...

Over the past few years, the syndrome of streptococcosis has been associated with outbreaks in rainbow trout (Oncorhynchus mykiss, Walbaum) and caused significant economic losses in the aquaculture industry in Iran. The main purpose of this work was molecular identification of some causative agents of streptococcosis in rainbow trout. A total of 520 samples were collected from the head kidney o...
