The long polar fimbriae (lpf) operon and its flanking regions in bovine Escherichia coli O157:H43 and STEC O136:H12 strains [PDF]

, 2013
Long polar fimbriae (Lpf) are intestinal adhesins and important virulence factors of pathogenic Escherichia coli strains. We cloned and sequenced the lpf2-1 operon (lpf2ABCD) and its flanking regions of an intimin- and Shiga toxin-negative E.

Anti-tumor activity of Escherichia coli Shiga toxin A subunit delivered by SF9 insect cells

Journal of Pharmacological Sciences, 2018
Cancer remains a major health problem around the world. A Shiga toxin is a bacterial toxin often produced by Shigella dysenteriae and Escherichia coli. A subunit of the Shiga toxin (StxA) is a cytotoxic agent which could be used to induce death in cancer

Gene‐specific double‐stranded RNAs induce mortality in the South African mealybug Delottococcus aberiae

Pest Management Science, Volume 82, Issue 6, Page 5184-5194, June 2026.
Gene‐specific double‐stranded RNAs effectively silence essential genes in the invasive citrus pest Delottococcus aberiae, leading to significant mortality through both microinjection and oral delivery. These results provide proof of concept for RNA interference‐based biopesticides as selective and sustainable tools for citrus integrated pest management.

Shiga Toxin Profiles of Poultry-origin Escherichia coli Isolates with Low Levels of Antimicrobial Resistance to the Clinical and Laboratory Standard Institute-recommended Antibiotics for Surveillance in Human Beings

Indian Journal of Public Health
Background: Escherichia coli are the reservoirs of antimicrobial resistance (AMR) genes. Shiga toxin-producing E. coli of animal origin can cause severe life-threatening infections in man.

Shiga toxin type-2 (Stx2) induces glutamate release via phosphoinositide 3-kinase (PI3K) pathway in murine neurons.

Frontiers in Molecular Neuroscience, 2015
Shiga toxin-producing Escherichia coli (STEC) can cause central nervous system (CNS) damage resulting in paralysis, seizures, and coma. The key STEC virulence factors associated with systemic illness resulting in CNS impairment are Shiga toxins (Stx ...

Environmental Preferences and Functional Variations of Methanotrophs in Northeast Qinghai‐Tibet Plateau Wetlands

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Significant environmental preference between type I and type II methanotrophs is regulated by soil ion concentration (pH and electrical conductivity) in wetlands. Type II methanotrophs (Methylocystis, etc.) contributes more to soil methane oxidation than type I methanotrophs.

Toxin Gene Expression by Shiga Toxin-Producing Escherichia coli: the Role of Antibiotics and the Bacterial SOS Response

Emerging Infectious Diseases, 2000
Toxin synthesis by Shiga toxin-producing Escherichia coli (STEC) appears to be coregulated through induction of the integrated bacteriophage that encodes the toxin gene.
