Elucidating the Staphylococcus aureus TSST‐1 Regulatory Network as a Response to Vaginal pH
Toxic shock syndrome toxin‐1 (TSST‐1) is a potent Staphylococcus aureus superantigen responsible for menstrual toxic shock syndrome (mTSS). Regulation of TSST‐1 is controlled by multiple systems including the stand‐alone transcriptional regulators CcpA and SarA and two‐component systems including the redox sensor SrrAB, the membrane stress sensor SaeRS,

How Host Phylogeny, Diet, and Habitat Affect Gut Microbial Diversity in Wild Snakes
Gut microbiota plays critical roles in host digestion, immune regulation, neurochemical signaling, and metabolic homeostasis. Based on wild snakes (73 individuals from 23 species) from China, we explored the composition, characteristics, and functions of gut microbes across different groups using fecal metagenomic samples; further we explored the ...

The effect of Staphylococcus aureus carriage in late pregnancy on antibody levels to staphylococcal toxins in cord blood and breast milk. [PDF]
We investigated the effect of carriage of Staphylococcus aureus in the later stages of pregnancy on levels of antibody specific to the S. aureus toxins, staphylococcal enterotoxin B (SEB), staphylococcal enterotoxin C (SEC) and toxic shock syndrome toxin-

Staphylococcal Enterotoxin Superantigens
Staphylococcal enterotoxins (SE) are a family of structurally related proteins that are produced by Staphylococcus aureus. They play a role in the pathogenesis of food poisoning and are the most potent activators of T lymphocytes known. The receptors for SE on antigen-presenting cells are major histocompatibility complex class II molecules.

Food Safety and Nutritional Aspects of Plant‐Based Dairy and Meat Alternatives: A Review
Plant‐based dairy and meat alternatives (PBDA and PBMA) offer sustainability benefits but also introduce chemical and microbiological hazards to the diet. Key concerns include emerging mycotoxins, heavy metals, process contaminants, and heat‐resistant spore‐forming bacteria.

Background: Recent studies suggest that Staphylococcus aureus enterotoxin sensitization is a risk factor for asthma. However, there is a paucity of epidemiologic evidence on adult-onset asthma in community-based populations.

ABSTRACT Genome sequencing is the gold standard for microbial identification. However, it fails to distinguish closely related species with overlapping genetic features. This is the case of Bacillus cereus and Bacillus cytotoxicus, two members of the B. cereus group with distinct pathogenic profiles. While B. cereus, a well‐known opportunistic pathogen
