Assay of Staphylococcal Enterotoxin B by Latex Agglutination

Experimental Biology and Medicine, 1968
SummaryStaphylococcal enterotoxin B (SEB) may be assayed by a simple and rapid latex-fixation test, with sensitivity improved by several orders of magnitude over conventional methods. Latex particles, coated with specific antitoxin under carefully controlled conditions, were exquisitely sensitive indicators of toxin. The minimal detection limit, 2 × 10-

Effect of Staphylococcal Enterotoxin B on the Electroencephalogram of Monkeys [PDF]

Applied Microbiology, 1967
A highly purified preparation of staphylococcal enterotoxin B was administered intravenously, 1 mg/kg, to rhesus monkeys. Electroencephalograms (EEG) were recorded from electrodes attached to the skin or implanted on the dura. The dose of toxin employed consistently produced a sequence of vascular collapse followed by death; in control studies, animals

Staphylococcal enterotoxin B administration in pregnant rats alters the splenic lymphocyte response in adult offspring rats

BMC Microbiology, 2017
BackgroundOur previous study suggested that SEB exposure in pregnant rats could lead to the change of T cells subpopulation in both peripheral blood and thymus of the offspring rats.

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

Molecular Microbiology, Volume 126, Issue 2, Page 220-235, August 2026.
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,

Upcycling Pomegranate Peel Into Functional Yoghurt: Chemical Profile, Antioxidant Capacity, and Anti–Staphylococcus aureus Activity

Food Safety and Health, Volume 4, Issue 3, Page 709-720, July 2026.
Pomegranate peel extract enhanced the nutritional, physicochemical, and microbiological qualities of yoghurt. It is a rich source of polyphenolic compounds that eliminates Staphylococcus aureus in yoghurt at 0.1% and 0.3% concentrations without altering its pH value. ABSTRACT The use of natural additives, particularly pomegranate peel extract (PPE), to

Food Safety and Nutritional Aspects of Plant‐Based Dairy and Meat Alternatives: A Review

Food Science &Nutrition, Volume 14, Issue 7, July 2026.
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.

Intratumoral Microbiota in Tumor: Current Understandings and Future Perspectives

MedComm, Volume 7, Issue 7, July 2026.
Intratumoral bacteria are emerging as active regulators of cancer evolution rather than bystanders. This review outlines how tumor‐resident microbes drive tumor initiation and growth by inducing genomic instability, epigenetic reprogramming, oncogenic signaling, and chronic inflammation, while promoting metastatic spread via invasion, angiogenesis ...

Rhinosinusitis derived Staphylococcal enterotoxin B possibly associates with pathogenesis of ulcerative colitis

BMC Gastroenterology, 2005
Background During clinical practice, we noticed that some patients with both ulcerative colitis (UC) and chronic rhinosinusitis (CRS) showed amelioration of UC after treatment of CRS. This study was designed to identify a possible association between CRS
