What is STEC O157?
Shiga toxin-producing E. coli (STEC) strains can cause serious illness in humans by producing toxins that can severely damage the lining of your intestines and kidneys. Infection with STEC strains can lead to serious complications like hemolytic uremic syndrome (HUS), which sometimes is fatal.
What groups Diarrheagenic E. coli are divided?
Diarrhoeagenic E. coli are a diverse group of bacteria that are currently separated into seven pathotypes (ETEC, EPEC, EHEC, EAEC, STEAEC, EIEC and DAEC). Through production of various toxins and virulence factors, these organisms are capable of causing a spectrum of diarrhoeal disease in infants and travellers.
Which toxin does O157 H7 produce?
Shiga toxin-producing Escherichia coli O157: H7, is an enterohemorrhagic bacterial strain that is an important food and a waterborne pathogen that causes diarrhea, hemorrhagic colitis, and hemolytic-uremic syndrome (HUS) in humans.
What does Enteropathogenic E coli do?
Enteropathogenic Escherichia coli Infection Induces Diarrhea, Intestinal Damage, Metabolic Alterations, and Increased Intestinal Permeability in a Murine Model. Enteropathogenic E. coli (EPEC) are recognized as one of the leading bacterial causes of infantile diarrhea worldwide.
Who discovered E. coli O157?
Dr. Lee Riley (pictured above) and colleagues authored the first paper describing an outbreak of hemorrhagic colitis associated with E. coli O157:H7. The outbreaks involved 47 people who became ill from consumption of undercooked hamburgers prepared by Restaurant A (McDonalds) restaurant chains in Oregon and Michigan.
What does EPEC stand for?
Enteropathogenic Escherichia coli (EPEC) are important diarrheal pathogens of young children.
What does H7 mean in E. coli O157?
Abstract. Enterohemorrhagic Escherichia coli O157:H7 is a major foodborne pathogen causing severe disease in humans worldwide. Healthy cattle are a reservoir of E.
What is the purpose of using CHROMagar O157?
CHROMagar O157 is intended for the isolation, differentiation and presumptive identification of. E. coli O157:H7. Due to the chromogenic substrates in the medium, colonies of E. coli O157:H7. produce a mauve color, thus allowing presumptive identification from the primary isolation plate.
What is BBL™CHROMagar™O157?
BBL™CHROMagar™O157 Escherichia coli serotype O157:H7 is a human pathogen associated with hemorrhagic colitis. Traditionally, this organism has been differentiated from its nonpathogenic counterparts using media containing sorbitol.
What is CHROMagar technology?
