Published in 2020 at "Lwt - Food Science and Technology"

DOI: 10.1016/j.lwt.2020.109956

Abstract: Abstract The behavior of two enterotoxigenic strains of Staphylococcus aureus (264 and 137) at two inoculation levels (ca. 2.3 and 4.2 log10 CFU/mL) was evaluated during artisanal kefir manufacture using three kefir grains (‘A’, ‘C’ and… read more here.

Published in 2021 at "Journal of proteome research"

DOI: 10.1021/acs.jproteome.1c00886

Abstract: We addressed here the need for improved sensitivity of top-down mass spectrometry for identification, differentiation, and absolute quantification of sequence variants of SEA, a bacterial toxin produced by Staphylococcus aureus and regularly involved in food… read more here.

Published in 2019 at "Scientific Reports"

DOI: 10.1038/s41598-019-51356-w

Abstract: Enterotoxin-based adjuvants including cholera toxin and heat-labile toxin (LT) are powerful manipulators of mucosal immunity; however, past clinical trials identified unacceptable neurological toxicity when LT or mutant AB5 adjuvant proteins were added to intranasal vaccines.… read more here.

Published in 2017 at "FEMS Microbiology Letters"

DOI: 10.1093/femsle/fnx232

Abstract: This study aimed to investigate classical enterotoxin (sea to see) and mecA genes, by polymerase chain reaction and anitimicrobial susceptibility, by disk diffusion test of Staphylococcus aureus isolated from minas frescal cheese (MFC). All methicillin-resistant… read more here.

Published in 2017 at "Cellular Microbiology"

DOI: 10.1111/cmi.12684

Abstract: Bacillus cereus is an opportunistic pathogen that often causes foodborne infectious diseases and food poisoning. Non‐hemolytic enterotoxin (Nhe) is the major toxin found in almost all enteropathogenic B. cereus and B. thuringiensis isolates. However, little… read more here.

Published in 2019 at "Infection and Immunity"

DOI: 10.1128/iai.00866-19

Abstract: Modeling host-pathogen interactions with human intestinal epithelia using enteroid monolayers on permeable supports (such as Transwells) represents an alternative to animal studies or use of colon cancer-derived cell lines. However, the static monolayer model does… read more here.

Published in 2025 at "Veterinary Research"

DOI: 10.1186/s13567-025-01540-w

Abstract: Enterotoxigenic Escherichia coli (ETEC) is a common cause of diarrhea in humans and animals, including pigs. Enterotoxins are important virulence factors for ETEC. Although much is known about the mechanism of enterotoxin-induced diarrhoea, less is… read more here.

Published in 2020 at "AMB Express"

DOI: 10.1186/s13568-020-01152-x

Abstract: Pathogenicity of Staphylococcus aureus is induced by staphylococcal enterotoxin B (SEB). A mutant form of SEB (mSEB) is immunogenic as well as less toxic. Recombinant mSEB and SEB were expressed in pET28a prokaryotic plasmids. Tumor… read more here.

Published in 2020 at "PLoS ONE"

DOI: 10.1371/journal.pone.0238153

Abstract: Bacillus cereus is a foodborne pathogen causing emesis and diarrhea in those affected. It is assumed that the non-hemolytic enterotoxin (Nhe) plays a key role in B. cereus induced diarrhea. The ability to trace Nhe… read more here.
