Produção de enterotoxinas e da toxina da síndrome do choque tóxico por cepas de Staphylococcus aureus isoladas na mastite bovina Production of enterotoxins and toxic shock syndrome toxin by Staphylococcus aureus strains isolated from bovine mastitis

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2007
A total of 72 strains of Staphylococcus aureus were examined for the production of staphylococcal enterotoxins (SE) A, B, C, D and toxic shock syndrome toxin (TSST-1).

Local Epidermal Growth Factor Receptor Signaling Mediates the Systemic Pathogenic Effects of Staphylococcus aureus Toxic Shock Syndrome. [PDF]

PLoS ONE, 2016
Secreted factors of Staphylococcus aureus can activate host signaling from the epidermal growth factor receptor (EGFR). The superantigen toxic shock syndrome toxin-1 (TSST-1) contributes to mucosal cytokine production through a disintegrin and ...

Detection of toxic shock toxin (tst) gene in Staphylococcus aureus isolated from bovine milk samples [PDF]

Bulgarian Journal of Veterinary Medicine, 2017
Staphylococcus aureus is a major causative pathogen of clinical and subclinical mastitis in dairy cattle all over the world. This agent produces a variety of extracellular toxins and virulence factors in-cluding toxic shock syndrome toxin-1 (TSST-1 ...

Targeted Proteomics Analysis of Staphylococcal Superantigenic Toxins in Menstrual Fluid from Women with Menstrual Toxic Shock Syndrome (mTSS)

Toxins, 2022
Menstrual toxic shock syndrome (mTSS) is a rare life-threatening febrile illness that occurs in women using intravaginal menstrual protection. It is caused by toxic shock syndrome toxin 1 (TSST-1) produced by Staphylococcus aureus, triggering a sudden ...

Elucidating the Staphylococcus aureus TSST‐1 Regulatory Network as a Response to Vaginal pH

Molecular Microbiology, EarlyView.
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,

Modeling Effects of Rumination on Free Recall Using ACT‐R

Topics in Cognitive Science, EarlyView.
Abstract Ruminative thinking, characterized by a recurrent focus on negative and self‐related thought, is a key cognitive vulnerability marker of depression and, therefore, a key individual difference variable. This study aimed to develop a computational cognitive model of rumination focusing on the organization and retrieval of information in memory ...

Environmental factors affecting toxic shock syndrome toxin-1 (TSST-1) synthesis [PDF]

Journal of Medical Microbiology, 1987
The production of toxic shock syndrome toxin-1 (TSST-1) was studied in batch and continuous culture of Staphylococcus aureus strain 1169 in a carbohydrate-free chemically defined medium (CDM). In continuous culture oxygen- and arginine-limitation were required for steady-state TSST-1 synthesis. Aeration suppressed toxin synthesis.

Inflammatory Stress Response During Pregnancy as a Connecting Link in Intergenerational Risk Cascades

Developmental Psychobiology, Volume 68, Issue 4, July 2026.
ABSTRACT Pregnancy represents a critical juncture for intergenerational transmission of stress‐related health vulnerabilities when child‐bearers’ history of maltreatment may precipitate stress responses that adversely impact maternal and fetal outcomes.

Antarctic Sea‐Ice Loss Enhances East Asian Summer Precipitation Through Tropical Ocean Warming

Earth's Future, Volume 14, Issue 7, July 2026.
Abstract Antarctic sea ice projected to have large reduction associated with increasing greenhouse gases, with potential impacts extending beyond the Southern Hemisphere. However, its influence on East Asian climate is not fully understood. Using Earth system model experiments and multi‐model simulations, we show that Antarctic sea‐ice loss by the end ...
