The exotoxins ofCorynebacterium ulcerans [PDF]

Journal of Hygiene, 1982
SummaryThe exotoxins produced by ten strains ofC. ulcerans(two human, six bovine and two equine) have been studied. On the criteria of toxin–antitoxin neutralisation and immunoprecipitation tests using highly specific diphtheria andC. ovisantitoxins with crude toxic filtrates, (NH4)2SO4concentrates, and partially purified chromatographic preparations ...

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.

A Comprehensive Microbial Gene Catalog of the Human Airway Microbiome Across Anatomical Sites and Geographic Regions

Advanced Science, EarlyView.
An integrated Human Airway Microbiome Gene Catalog (iHAMGC) is constructed from 12,273 metagenomic airway samples, providing a high‐resolution reference of respiratory microbial genes. The catalog enables systematic exploration of taxonomic and functional variation across airway niches and geographic regions, revealing site‐specific and region ...

Antibody kinetics against tetanus toxoid before and after primary vaccination of foals

Equine Veterinary Journal, EarlyView.
Abstract Background Vaccination recommendations for foals against Clostridium tetani vary. Available studies assessing foal immune responses, maternal antibody interference, or individual variation often used small foal numbers. Objectives To quantify antibody responses after tetanus vaccination in foals and explore associations with passively ...

A Comprehensive Study of Bidirectional Interactions Between the Human Microbiome and Blood Malignancies and Hematologic Conditions: Focus on Novel Therapeutic Strategies

Journal of Clinical Laboratory Analysis, EarlyView.
Microbiota‐targeted therapeutic strategies in hematological disorders. aHSCT: Transplanted immune cells from the donor may attack the recipient's tissues, especially when damage to the intestinal epithelium disrupts the gut microbiota, contributing to GVHD. Maintaining a balanced gut microbiota that supports immune regulation helps reduce GVHD risk and

Caspase-1-driven neutrophil pyroptosis and its role in host susceptibility to Pseudomonas aeruginosa.

PLoS Pathogens, 2022
Multiple regulated neutrophil cell death programs contribute to host defense against infections. However, despite expressing all necessary inflammasome components, neutrophils are thought to be generally defective in Caspase-1-dependent pyroptosis.
