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.

Case of Streptococcus suis meningitis in a French cooker and review [PDF]

Journal of Microbiology and Infectious Diseases, 2016
Streptococcus suis is an emerging zoonotic pathogen, increasingly reported worldwide and especially in Asia. S. suis remains rare in France but is responsible for outbreaks in Asia, causing meningitis, septicemia, endocarditis, arthritis and septic ...

Streptococcus suisinfections in birds [PDF]

Avian Pathology, 1994
Four cases of Streptococcus suis infection were diagnosed in psittacine birds and four others in zebrafinches, bullfinches, canaries and a duck. The main clinical and pathological manifestation was septicaemia with multiple sudden deaths in nestlings, young and adults. Other cases were solitary, with evidence for secondary involvement of S. suis.

How phagocytic cells kill bacteria: Lessons from a professional killer

FEBS Open Bio, EarlyView.
How phagocytic cells ingest and kill bacteria has been studied for more than a century, but many questions remain unanswered. The study of the amoeba Dictyostelium discoideum brings new answers, and new questions. Professional phagocytic cells such as neutrophils and macrophages, as well as free‐living soil amoebae like Dictyostelium discoideum, employ

Streptococcus suis Serotype 2 Capsule In Vivo

Emerging Infectious Diseases, 2016
Many Streptococcus suis isolates from porcine endocarditis in slaughterhouses have lost their capsule and are considered avirulent. However, we retrieved capsule- and virulence-recovered S. suis after in vivo passages of a nonencapsulated strain in mice,

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

FEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Patient‐Derived 3D Heart‐On‐a‐Chip Model of Dilated Cardiomyopathy With Embedded Bead‐Based Mapping of Tissue Contractility

Advanced Healthcare Materials, EarlyView.
A heart‐on‐a‐chip model of dilated cardiomyopathy is developed from patient‐derived induced pluripotent stem cells. The model recapitulates key disease phenotypes and enables functional assessment through integrated bead‐based tracking and pillar deflection measurements.

Auranofin Has Advantages over First-Line Drugs in the Treatment of Severe Streptococcus suis Infections

Antibiotics, 2020
Streptococcal toxic shock-like syndrome (STSLS) likely occurs when an individual is infected with the Streptococcus suis (S. suis) epidemic strain and is characterized by a cytokine storm, multiple organ dysfunction syndrome (MODS) and a high incidence ...

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Occupational Exposure to Streptococcus suis among US Swine Workers

Emerging Infectious Diseases, 2008
Despite numerous cases of human infection with Streptococcus suis worldwide, human disease is rarely diagnosed in North America. We studied 73 swine-exposed and 67 non–swine-exposed US adults for antibodies to S. suis serotype 2.
