E.coli Infection, Causes, Symptoms and Treatment.
E.coli bacterium

Escherichia coli (E.coli) is the bacterium that lives in the digestive tracts of humans and animals.

E. coli bacteria are of many types and most of them are harmless. But some few strains of E.coli can cause bloody diarrhea, urinary tract infections or other infections, severe anemia or kidney failure, which can lead to death.

Causes of E. coli Infection
E. coli infection is transmitted through direct contact with the infected feces, or stool, of humans or animals. This can happen when you drink contaminated water or eat food that has been contaminated by feces. E.coli infection can also spread from an infected person to person due to improper washing of hand after passing stool in the toilet.


Symptoms of intestinal infection due to E. coli can include:

abdominal cramping

sudden, severe watery diarrhea that may change to bloody stools


loss of appetite/nausea

vomiting (uncommon)



Symptoms of a severe E. coli infection may include:

bloody urine

decreased urine output
pale skin
