Bisdemethoxycurcumin Reduces Methicillin-Resistant Staphylococcus aureus Expression of Virulence-Related Exoproteins and Inhibits the Biofilm Formation

Toxins, 2021
Methicillin-resistant Staphylococcus aureus (MRSA) is a major pathogen of nosocomial infection, which is resistant to most antibiotics. Presently, anti-virulence therapy and anti-biofilm therapy are considered to be promising alternatives. In the current

Bacillus cereus extracellular vesicles act as shuttles for biologically active multicomponent enterotoxins

Cell Communication and Signaling, 2023
Background Extracellular vesicles (EVs) from Gram-positive bacteria have gained considerable importance as a novel transport system of virulence factors in host–pathogen interactions.

Bacillus cereus non-haemolytic enterotoxin activates the NLRP3 inflammasome

Nature Communications, 2020
The Bacillus haemolytic enterotoxin haemolysin BL has been shown to activate the NLRP3 inflammasome. Here the authors show that a non-haemolytic enterotoxin (NHE) from B.

Prevalence, distribution, enterotoxin profiles, antimicrobial resistance, and genetic diversity of Bacillus cereus group isolates from lettuce farms in Korea

Frontiers in Microbiology, 2022
Lettuce wraps are popular in Korean cuisine for their high nutritional value and versatility as healthy additions to multiple dishes. Microbial contamination of lettuce is a major concern, as lettuce is consumed fresh without cooking.

Antibiotic sensitivity patterns and molecular detection of Enterotoxin genes in Staphylococcus aureus isolated from frozen muscle foods

Croatian Journal of Food Science and Technology, 2023
Stapylococcus aureus is considered to be the most common pathogen in commonly consumed and improperly stored frozen foods. Hence, this study investigated the antibiotic sensitivity patterns and the occurrence of enterotoxin genes (sea and seb) in S ...

γ Irradiation of Staphylococcal Enterotoxin B [PDF]

Applied Microbiology, 1967
The inactivation of enterotoxin B by γ irradiation was studied by use of single-and double-gel-diffusion assay techniques. Enterotoxin B (99+% purity) was suspended either in 0.04 m Veronal buffer ( p H 7.2) or in milk, dispensed and heat-sealed in borosilicate glass vials, and irradiated ...

Chromosomal locus for staphylococcal enterotoxin B [PDF]

Infection and Immunity, 1978
The genetic locus of staphylococcal enterotoxin B (SEB) was investigated in the Staphylococcus aureus food-poisoning isolates, strains S6 and 277. Direct neutral sucrose gradient centrifugation analysis of sodium dodecyl sulfate-sodium chloride-mediated cleared lysates demonstrated that strain S6 contained a single 37S plasmid.

Staphylococcal Enterotoxin B: Solid-Phase Radioimmunoassay [PDF]

Applied Microbiology, 1971
An immunoassay employing 125 I-labeled enterotoxin B and polystyrene tubes coated with specific antibody was used for assaying purified and crude enterotoxin. Antibody was adsorbed to untreated polystyrene tubes.
