Starch-like Polysaccharide of Streptococcus pyogenes [PDF]

open access: yesNature, 1960
MANY strains of Lancefield group A streptococci synthesize a starch-like polysaccharide when grown on a medium containing maltose or maltose-polymers1, and some of these strains also produce an extracellular amylase2. It has been shown that amylase-negative starch-accumulating strains are associated with acute glomerulonephritis and acute rheumatic ...

CRISPR/Cas9‐based white pupae mutant lines in Bactrocera spp. for sterile insect technique applications

open access: yesInsect Science, EarlyView.
Bactrocera fruit flies are significant horticultural pests that cause major economic losses. A “neoclassical approach” incorporating genome editing via CRISPR/Cas9 to develop genetic sexing strains (GSS) could render the sterile insect technique (SIT) against these pests more efficient and cost‐effective.

The return of metabolism: biochemistry and physiology of glycolysis

open access: yesBiological Reviews, EarlyView.
ABSTRACT Glycolysis is a fundamental metabolic pathway central to the bioenergetics and physiology of virtually all living organisms. In this comprehensive review, we explore the intricate biochemical principles and evolutionary origins of glycolytic pathways, from the classical Embden–Meyerhof–Parnas (EMP) pathway in humans to various prokaryotic and ...

The pneumococcal response to oxidative stress includes a role for Rgg [PDF]

open access: yes, 2009
Streptococcus pneumoniae resides in the oxygen-rich environment of the upper respiratory tract, and therefore the ability to survive in the presence of oxygen is an important aspect of its in vivo survival. To investigate how S.

Repeat Intraocular Sampling and Microbiological Testing in Infectious Endophthalmitis: A 27‐Year Prospective Observational Study at an Australian Statewide Tertiary Referral Centre

open access: yesClinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background Endophthalmitis requiring multiple ocular tissue sampling for microbiological testing is uncommon and has not been previously studied. This study aims to analyse cases with at least two ocular tissue samplings and testing of different ocular samples against culture yields. Methods A 27‐year prospective observational study using data

Streptococcus pyogenes-purpura fulminans as an invasive form of group A streptococcal infection

open access: yesAnnals of Clinical Microbiology and Antimicrobials, 2018
Background Streptococcus pyogenes is an uncommon pathogen of purpura fulminans, and the pathogenesis of S. pyogenes-purpura fulminans remains unclear because of paucity of cases. We reported a pediatric case of S.

Unwelcome neighbours: Tracking the transmission of Streptococcus equi in the United Kingdom horse population

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Strangles (Streptococcus equi infection) remains endemic in the UK, with ~300 laboratory diagnoses annually. Sub‐clinically infected long‐term carriers are considered a key driver of endemicity. Analysing genomes of circulating strains could provide valuable transmission insights of this pathogen.

Streptococcus pyogenesprimary peritonitis [PDF]

open access: yesBMJ Case Reports, 2018
Streptococcus pyogenes, a Gram-positive bacterium, is a rare cause of primary peritonitis. Diagnosed on imaging and with positive growth in blood cultures, a case of primary peritonitis caused byS. pyogenesis discussed here, with a brief literature review, and used to discuss several key principles of antibiotic use, including selection of antibiotic ...
