Diarrheal and Environmental Isolates of Aeromonas spp. Produce a Toxin Similar to Shiga-Like Toxin 1
Current Microbiology, 1996Diarrheal and environmental isolates of 39 strains of Aeromonas spp. were studied for detection of virulence factors. Although these 39 strains did not produce either heat-labile or heat-stable enterotoxins, culture filtrates of 31 strains produced cytopathic effects on Vero cells. Among these, culture filtrates of three strains of Aeromonas hydrophila

Shiga Toxin 1 and 2 Induce Apoptosis in the Amniotic Cell Line WISH
Journal of the Society for Gynecologic Investigation, 2002The aim of this study was to evaluate the toxicity of Shiga toxin (Stx) 1 and 2 on amniotic cells in vitro.WISH cells, which were derived from human amniotic cells, and Vero cells were cultured with or without Stxs. After 24 hours of culture, cell viability was measured by Cell Counting Kit-8, and extracted DNA was electrophoresed on a 1% agarose gel ...

The hemolytic uremic syndrome is a life-threatening sequela that occurs after infection with Shiga toxin (Stx)-producing Escherichia coli (STEC) or Shigella dysenteriae type 1, and Stx is responsible for initiating this syndrome. An STEC isolate can express Stx1, Stx2, or both, but antisera to Stx1 and Stx2 are not cross-neutralizing.

Ricin, Shiga-like toxin 1 (Stx1) and Shiga-like toxin 2 (Stx2) are ribosome inactivating proteins (RIPs) that catalytically remove an adenine residue from the highly conserved α-sarcin/ricin loop (SRL) in the large ribosomal subunit, inhibiting the translocation step of protein synthesis.

Shiga toxins (Shigella dysenteriae serotype 1, Escherichia coli)
1997Abstract The Shiga toxins (also known as verotoxins) comprise a family of toxins that inhibit protein synthesis in intoxicated cells (for reviews see O’Brien and Holmes 1987; O’Brien et al. 1992; Obrig 1994). The holotoxin consists of an A polypeptide (Mr 32 000) that has N-glycosidase activity which removes a single adenine residue from
