Sep 6, 2024 · INTRODUCTION. Escherichia coli that contain genes encoding Shiga toxins 1 and/or 2 are important human pathogens; these are referred to as Shiga toxin-producing Escherichia coli (STEC). Some strains, such as E. coli O157:H7, cause severe disease including painful bloody diarrhea, as well as hemolytic uremic syndrome (HUS) in some cases.
Aug 22, 2024 · Clinical features and sequelae. STEC infection causes gastroenteritis, accompanied by stomach cramps, abdominal pain, vomiting, and diarrhoea, which is often bloody. The incubation period is from three to eight days after exposure. The infective dose of STEC is low: thought to be fewer than 100 bacteria.
Escherichia coli (E. coli) bacteria are bacillus-shaped bacteria. Most strains of E. coli that reside within us are harmless and even provide beneficial functions, such as food digestion, nutrient absorption, and the production of vitamin K. Other strains, however, are pathogenic and can cause intestinal disease, urinary tract infections, and ...
