What does EHEC cause?

What does EHEC cause?

EHEC is a strain of E. coli that produces a toxin called Shiga toxin. The toxin causes damage to the lining of the intestinal wall. In 1982, EHEC was found as the cause of bloody diarrhea that developed after eating undercooked or raw hamburger meat contaminated with the bacteria.

Is EHEC pathogenic?

Enterohemorrhagic Escherichia coli (EHEC) is a highly pathogenic bacterial strain capable of causing watery or bloody diarrhea, the latter termed hemorrhagic colitis, and hemolytic-uremic syndrome (HUS).

What is EHEC and EPEC?

EHEC and EPEC are sophisticated pathogens that display several virulence-associated traits, some of which are also found in other bacterial pathogens (82). The mechanisms by which EPEC and EHEC intimately adhere to epithelial cells represent the most studied feature in their pathogenesis.

What is ETEC and EHEC?

Enterotoxigenic Escherichia coli (ETEC) and Enterohemorrhagic Escherichia coli (EHEC) are major food‐ and water‐borne pathogens that constitute a serious public health threat in low‐income and developed countries, respectively.

How does EHEC enter the body?

EHEC is spread from animals to people by eating raw or uncooked ground beef, pork, lamb, or sausage, unpasteurized milk, apple juice or apple cider, or contaminated spinach, lettuce, sprouts, or water. EHEC can cause abdominal cramps, severe bloody diarrhea, non-bloody diarrhea, fatigue, and nausea.

What is the difference between EHEC and STEC?

Cite. The term enterohemorrhagic Escherichia coli (EHEC) is used to designate a subset of Shiga toxin (Stx)–producing E. coli (STEC; also known as verotoxin-producing E. coli [VTEC]) that cause severe diseases in humans, including bloody diarrhea and the hemolytic uremic syndrome (HUS).

Is EHEC intracellular?

In contrast, EHEC O157:H7 remained extracellular and intimately attached to the epithelial cell surface.

What does ETEC mean?

Enterotoxigenic Escherichia coli (E. coli), or ETEC, is an important cause of bacterial diarrheal illness. Infection with ETEC is the leading cause of travelers’ diarrhea and a major cause of diarrheal disease in lower-income countries, especially among children.

What does EHEC stand for?

Abstract. Enterohemorrhagic Escherichia coli (EHEC) serotype O157:H7 is a human pathogen responsible for outbreaks of bloody diarrhea and hemolytic uremic syndrome (HUS) worldwide.

How do you get EHEC?

How is EHEC treated?

Treatment. The mainstay of treatment for EHEC infection is supportive. Although E. coli is sensitive to most commonly used antibiotics, antibiotics have not been shown to alleviate symptoms, reduce carriage of the organism, or prevent hemolytic-uremic syndrome.

What are Enteropathogens?

Definition of enteropathogenic : tending to produce disease in the intestinal tract enteropathogenic bacteria.
