Characterization of Antibiotic and Biocide Resistance Genes and Virulence Factors of Staphylococcus Species Associated with Bovine Mastitis in Rwanda [PDF]

, 2020
The present study was conducted from July to August 2018 on milk samples taken at dairy farms in the Northern Province and Kigali District of Rwanda in order to identify Staphylococcus spp. associated with bovine intramammary infection.

Toxic shock syndrome toxin 1 (TSST-1) production by staphylococci isolated from goats and presence of specific antibodies to TSST-1 in serum and milk [PDF]

Applied and Environmental Microbiology, 1991
The ability of staphylococcal strains isolated from different anatomical sites in 133 healthy goats to produce toxic shock syndrome toxin 1 (TSST-1) and the presence of antibodies to this toxin in serum and milk were studied. The enzyme-linked immunosorbent assay method was used to detect both the toxin and the presence of antibodies. Of a total of 342

The Complexity of Electroencephalographic Signal Decreases during the Social Stress

Journal of Medical Signals and Sensors, 2023
Social stress affects brain function. Trier social stress test (TSST) is a standard test to assess it. The study aimed to analyze the electroencephalographic (EEG) recording during and after TSST in healthy subjects.

Colony immunoblot assay for the detection of staphylococcal toxic shock syndrome toxin 1 (TSST-1) with anti-TSST-1 F(ab')2 fragments [PDF]

Journal of Clinical Microbiology, 1989
Toxic shock syndrome toxin 1 (TSST-1), an exoprotein of Staphylococcus aureus, is strongly implicated in the pathogenesis of TSS. Detection of TSST-1, however, is often hindered in immunoassays because of the cosecretion of protein A, a genetic trait which appears to be coordinately expressed with other exoproteins in S. aureus.

The effect of Staphylococcus aureus carriage in late pregnancy on antibody levels to staphylococcal toxins in cord blood and breast milk. [PDF]

, 2008
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-

Analysis of the early response to TSST-1 reveals Vβ-unrestricted extravasation, compartmentalization of the response, and unresponsiveness but not anergy to TSST-1 [PDF]

Journal of Leukocyte Biology, 2008
AbstractStaphylococcal toxic shock syndrome toxin 1 (TSST-1) is the major cause of toxic shock syndrome and is important in the pathophysiology of staphylococcal septic shock. Our study about the biological effects of TSST-1 in the rabbit 3 and 6 h and 7 days postinjection provides evidence that TSST-1 induces leukopenia, lymphopenia, and monocytopenia

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.

Toxic Shock Syndrome Toxin 1 Evaluation and Antibiotic Impact in a Transgenic Model of Staphylococcal Soft Tissue Infection

mSphere, 2019
Nonmenstrual toxic shock syndrome (nmTSS), linked to TSST-1-producing CC30 Staphylococcus aureus, is the leading manifestation of toxic shock syndrome (TSS). Due to case rarity and a lack of tractable animal models, TSS pathogenesis is poorly understood.

Toxic Shock Syndrome Toxin 1 Induces Immune Response via the Activation of NLRP3 Inflammasome

Toxins, 2021
Staphylococcus aureus is a Gram-positive opportunistic pathogen which causes infections in a variety of vertebrates. Virulence factors are the main pathogenesis of S.

Alcohol craving under stress in healthy young men: A randomized laboratory study. [PDF]

Alcohol Clin Exp Res (Hoboken)
This study shows that acute social stress can increase alcohol craving in young men. Individuals with stronger mood and biological reactivity showed greater increases in craving. Two latent classes of stress‐craving effects emerged in exploratory analyses: one class showed stress‐induced craving increase while the other showed a decrease compared with ...
