7 paź 2024 · Among IPEC that contain shiga toxin (Stx)-producing E. coli (STEC), the bacilli strains are grouped genetically into the following pathotypes: (i) enteroinvasive E. coli (EIEC), which causes dysentery; (ii) enterotoxigenic E. coli (ETEC), which causes traveller’s diarrhoea; (iii) enteroaggregative E. coli (EAEC) (also termed EAggEC), which ...
Shiga toxins (Stxs) are classic bacterial toxins and major virulence factors of toxigenic Shigella dysenteriae and enterohemorrhagic Escherichia coli (EHEC). These toxins recognize a glycosphingolipid globotriaosylceramide (Gb3/CD77) as their receptor and inhibit protein synthesis in cells by cleaving 28S ribosomal RNA.
1 sie 2021 · Traceback investigations of three outbreaks of Shiga toxin-producing E. coli infections linked to romaine lettuce in 2018 and 2019 were examined to demonstrate challenges, limitations, and opportunities for improvement.
In recent years, a variety of alternative treatment approaches such as monoclonal antibodies or antisera directed against Shiga toxin, toxin receptor analogs, and several vaccination strategies have been developed and evaluated in vitro and in animal models. A few strategies have progressed to the clinical trial phase.
