Escherichia coli

Under a high magnification of 13671x, this scanning electron micrograph (SEM) depicted a single Gram-negative Escherichia coli bacterium of the strain O157:H7, which is one of hundreds of strains of this bacterium. Although most strains are harmless, and live in the intestines of healthy humans and animals, this strain produces a powerful toxin, which can cause severe illness.E. coli O157:H7 was first recognized as a cause of illness in 1982 during an outbreak of severe bloody diarrhea; the outbreak was traced to contaminated hamburgers. Since then, most infections have come from eating undercooked ground beef.The combination of letters and numbers in the name of the bacterium refers to the specific markers found on its surface, which distinguishes it from other types of E. coli.

Ein positives Ergebnis im Aminopeptidase-Test ist typisch für gramnegative Bakterien. English: Escherichia coli in the aminopeptidase test, showing a positive result (the microorganism has the enzyme L-alanine aminopeptidase, which is able to hydrolyze the substrate L-alanine-4-nitroanilide within the test strip, to form the amino acid L-alanine and 4-nitroaniline, which causes the yellow color).
