Group B streptococci, a European perspective with results of the DEVANI project [PDF]

, 2011
In 2011, neonatal group B streptococcal (GBS) diseases remain a global public health concern. Where consensus guidelines to detect and treat intrapartum women with GBS colonization have been widely adopted, incidence of neonatal early onset disease (EOD)

The crystal structure of the Borrelia burgdorferi nicotinamidase BBE22 resolves a long‐standing annotation error

FEBS Open Bio, EarlyView.
The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...

Ultra late onset group B streptococcal sepsis with acute renal failure in a child with urethral obstruction: a case report

Journal of Medical Case Reports, 2012
Introduction Group B streptococci are a well-known cause of early and late onset sepsis. In neonates and older children gram-negative bacteria are mostly found in urinary tract infections and urosepsis.

Thrombus Aspirates From Patients With Acute Ischemic Stroke Are Infiltrated by Viridans Streptococci

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Acute ischemic stroke may be due to embolism from ruptured atherosclerotic carotid arteries. DNA of oral bacteria, mainly the viridans streptococci group, has been detected in thrombus aspirates of patients with ischemic stroke as well as in ...

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Metabolic and Fluid Biomarkers Support Microglia Activation in Amyotrophic Lateral Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Amyotrophic lateral sclerosis is an incurable neurodegenerative disease involving motor neuron degeneration and metabolic and immune dysfunction. We combined clinical data, cerebrospinal fluid biomarkers and fluorodeoxyglucose positron emission tomography with magnetic resonance imaging to investigate the role of reactive microglia in disease ...

Occurence of the alp3 gene and the R28 protein in Group A streptococci

Bioingeniøren, 2011
Background: The protein R28 of group A streptococci (GAS) is nearly identical in structure to the alpha-like protein Alp3 of group B streptococci (GBS), and the two proteins cross-react immunologically. The purpose of this study was to test the frequency
