Escherichia coli was discovered by Theodor Escherich in 1885 after isolating it from the feces of a newborn. At first it was described as Bacterium coli commune, but then it was later named Escherichia coli (named for Escherich... who would've thought?). It wasn't until 1935, however, that it was found that E. coli was the cause of diarrhea in newborns!
Here is a list of some Biochemical characteristics of E. coli:
Characteristic | Reaction |
Lactose 37oC | Acid+, gas+ |
Lactose 44oC | Acid+, gas+ |
Indole 37oC | Usually produced |
Indole 44oC | Usually produced |
Mannitol Fermentation | +, usually with gas |
Methyl-Red | + |
Voges-Proskauer | - |
Citrate | - |
Urea | No hydrolysis |
H2S | No blackening |
Lysine Decarboxylase | + |
Gelatin Liquefaction | - |
There are 700 serotypes of E. coli based on O, H, and K antigens.
