Occurrence, diversity and antimicrobial resistance of Enterobacterales isolated from artisanal ‘coalho’ cheese produced in north‐eastern Brazil

International Journal of Dairy Technology, Volume 79, Issue 3, July‐September 2026.
Artisanal ‘coalho’ cheese from north‐eastern Brazil harbours diverse Enterobacterales, including strains with antimicrobial resistance, virulence‐associated genes and biofilm‐forming ability. Although resistance levels were generally low, the findings highlight the need for improved hygienic practices and continuous microbiological surveillance within ...

Factors released by LPS and/or Stx1-treated ASTs increase transendothelial permeability by reducing tight-junctions proteins expression on HUVECd.

, 2012
HUVECd seeded on culture plates (A,B,C) or in upper transwell chamber (D) were stimulated during 24 h with CM-Control, CM−LPS, CM−Stx1 or CM−LPS+Stx1. ZO-1 (A) and occludin (B) expression were evaluated by FACS.

Risk Ranking of Microbiological Hazards in Food (2015–2019)

Food Risk Assess Europe, Volume 4, Issue 3, July 2026.
Abstract Microbiological food safety risks arise from pathogens that can contaminate food at different points along the food chain. Exposure to these hazards can result in illnesses that can vary widely in severity and duration, depending on factors such as the specific pathogen involved, the amount of the pathogen ingested, and the susceptibility of ...

Production of hybrid-IgG/IgA plantibodies with neutralizing activity against Shiga toxin 1. [PDF]

PLoS ONE, 2013
Shiga toxin 1 (Stx1) is a virulence factor of enterohemorrhagic Escherichia coli, such as the O157:H7 strain. In the intestines, secretory IgA (SIgA) is a major component of the immune defense against pathogens and toxins. To form SIgA, the production of

Shiga Toxin 1–Producing Shigella sonnei Infections, California, United States, 2014–2015

Emerging Infectious Diseases, 2016
Shiga toxins (Stx) are primarily associated with Shiga toxin–producing Escherichia coli and Shigella dysenteriae serotype 1. Stx production by other shigellae is uncommon, but in 2014, Stx1-producing S.

Proline‐Rich Transmembrane Protein 2 Is Variably Expressed Across Excitatory and Inhibitory Neurons in Mouse Motor Circuits

Journal of Comparative Neurology, Volume 534, Issue 6, June 2026.
Prrt2, a causal gene for paroxysmal kinesigenic dyskinesia, was sparsely expressed in nigrostriatal dopaminergic neurons, but alternatively in excitatory (within the cerebral cortex and cerebellum) or inhibitory (within the basal ganglia) neurons in a region‐dependent manner, suggesting that Prrt2 functions in both the basal ganglia and cerebellar ...

Transcription Analysis of stx1, marA, and eaeA Genes in Escherichia coli O157:H7 Treated with Sodium Benzoate

Journal of Food Protection, 2008
Expression of the multiple antibiotic resistance (mar) operon causes increased antimicrobial resistance in bacterial pathogens. The activator of this operon, MarA, can alter expression of >60 genes in Escherichia coli K-12. However, data on the expression of virulence and resistance genes when foodborne pathogens are exposed to antimicrobial agents are

Factors released by LPS and Stx1-treated ASTs increased HUVECd activation.

, 2012
HUVECd were stimulated with CM-Control, CM−LPS, CM−Stx1, CM−LPS+Stx1 or with 0.5 µg/ml de LPS (HUVECd+LPS). ICAM-1 (A) and E-selectin (B) expression was evaluated by FACS after 12 h or 3 h of stimulation, respectively.
