  Shiga-like toxin - Wikipedia, the free encyclopedia
Shiga-like toxin is Shiga toxin produced by the bacteria E.
In 1977, researchers in Ottawa rediscovered the Shiga toxin produced by Shigella dysenteriae in E. coli [1].
The E. Coli version was named Verotoxin because of the ability of the toxic protein to kill Vero (African green monkey kidney) cells in culture.

Shiga Prefecture (滋賀県 Shiga-ken) is part of the Kinki region on Honshu island, Japan.
Shiga was known as Omi Province before the prefectural system was established.
Shiga shares a border with Fukui Prefecture in the north, Gifu Prefecture in the east, Mie Prefecture in the southeast, and Kyoto Prefecture in the west.

 SHIGA-Our Prefecture's Profile   (Site not responding. Last check: 2007-10-22)
Shiga Prefecture, located in about the middle of the Main Island of Japan, is known for the grand Omi Basin, and the lake of Biwa covering a sixth of the whole area of the prefecture.
Shiga is bordered by mountainous areas in every direction: Nosaka Mountains form its northern border with Fukui, Ibuki Mountains constitute the eastern border with Gifu, Suzuka Mountains form the south-eastern border with Mie, and Hira and Hiei Mountains constitute the western border with Kyoto.
Shiga itself was the political centre for some time, as we know from the old capital of Otsu in the reign of Tenchi emperor, and the castle of Azuchi in the reign of Nobunaga Oda, neither of which, however, exist now because of the frequent war flames.

Emerging Infectious Diseases; 9/1/2000; Hinrichs, S.H. We determined the prevalence of Shiga toxin-producing Escherichia coli (STEC) in diarrheal stool samples from Nebraska by three methods: cefixime-tellurite sorbitol MacConkey (CT-SMAC) culture, enterohemorrhagic E. coil (EHEC) enzyme immunoassay, and [stx.sub.1,2] polymerase chain reaction (PCR).
Disease caused by Shiga toxin-producing Escherichia coli (STEC) ranges from self-limiting diarrhea to hemorrhagic colitis and hemolytic uremic syndrome (HUS).
Multiplex PCR (3) was performed on isolated Shiga toxin-positive colonies to detect specific genes encoding Shiga toxins 1 and 2 ([stx.sub.1] and [stx.sub.2]), intimin (eaeA), and enterohemolysin A (ehxA).

Shigella toxin (also known as Shiga toxin, Shigella dysenteriae toxin or Stx) and Shigella-like toxins (also known as Shiga-like toxin 1, verotoxin 1, or Stx-1, and Shiga-like toxin 2, verotoxin 2 or Stx-2) are extremely toxic.
Shiga toxin containers to be removed from the chemical hood or BSC must be decontaminated (see Section 4.6.2) and placed in a labeled, unbreakable secondary container (see Section 4.3.2) prior to removal.
Spill of Shiga toxin inside the chemical hood or BSC: Small spills may be decontaminated by gently covering the spill with paper towels and flooding the area (starting at perimeter and working towards the center) to arrive at a solution of 0.1N NaOH.

The strain was isolated during a study of fecal STEC in 205 healthy and 139 diarrheic cattle on 12 beef farms in the state of São Paulo, Brazil, in February 2000; one case of STEC was found in a 1-month-old calf with diarrhea.
The STEC O118:H16 strain from Brazil was found to be similar for virulence genes (Shiga toxin 1 [stx1], intimin beta 1 [eae β1], and EHEC-hemolysin [E-hlyA]) and for antimicrobial drug resistance to STEC O118:H16 strains, which were isolated in different countries of Europe (1).

 ARS | Publication request: Cattle Lack Vascular Receptors for Escherichia Coli O157:h7 Shiga Toxins   (Site not responding. Last check: 2007-10-22)
Shiga toxins also bound to epithelium in selected areas of the duodenum.
However, Shiga toxins did not bind to the epithelium in gastrointestinal sites other than the duodenum, nor did they bind to blood vessels in any of the 6 intestinal and 5 extraintestinal organs examined.
We suggest that the lack of enterocyte and vascular receptivity for Shiga toxins may be an explanation as to why E. coli O157:H7 infections are usually asymptomatic in cattle and why systemic vascular lesions have not been reported in Shiga toxin-producing E. coli (STEC) infections in cattle.

We found that with as low as 0.3 micrograms swainsonine (a microgram is one one-millionth of a gram), the toxic effects of the "shiga toxins" on laboratory grown kidney cells were reduced by up to 100%.
These results demonstrate that swainsonine was able to protect susceptible cells from being killed by the "shiga toxins" and may ultimately be able to be used as a drug to treat the life threatening effects of Escherichia coli O157:H7 infections.
The primary receptor on the epithelial cell surface for Stx is the glycolipid receptor globotriaosylceramide, Gb3.

 Shiga toxin or Verotoxin: essential data
Note: although Shiga toxin and Verotoxin are treated as different entities by the Australia Commission, they are structurally and functionally identical and considered the same thing by the scientific community.
Like ricin A subunit, the A subunit of Shiga toxin is an N-glycosidase that modifies the RNA component of the ribosome to inactivate it and so bring a halt to protein synthesis leading to the death of the cell.
This is because Shiga toxin is usually taken in with contaminated food or water.

Infection with Shiga toxin-producing E. coli is a cause of bloody diarrhea and hemorrhagic colitis in humans, and has been linked with development of hemolytic uremic syndrome (HUS).
Because Shiga toxin-producing E. coli are non-invasive, it is thought that Shiga toxins gain access to the systemic vasculature from the gut lumen.
Currently, we are studying the effects of Shiga toxins on host signal transduction and gene regulation in vitro and in vivo, with the intention of delineating strategies for prevention of HUS following infection with Shiga toxin-producing E. coli.
