Escherichia coli (E. coli) -Types, infections, diagnosis and treatment


Escherichia coli (E. coli) is a gram negative bacterium Escherichia coli which is usually found in the contaminated food products. This bacterium contaminates in meat products and produces the powerful toxin which results in diarrhea in human body.

There are various types of E. coli like ETEC entero toxigenic Escherichia coli which is typically known as traveler’s diarrhea, EHEC entero hemorrhagic Escherichia coli which cause bloody diarrhea and VTEC Vero toxic Escherichia coli which converts watery diarrhea into the bloody diarrhea. E coli can be detected by X-gluc.

E. coli completes their life cycle in human as well as in animal’s intestine. It is generally present in the improper cooked meat and in sprouted beans and pulses. The symptom of Ecoli is similar to food poisoning like severe abdominal pain, nausea, and vomiting, sticky and watery diarrhea, fever.

How to find and diagnose Escherichia coli ?

There are typical signs to diagnose E. coli infection like abdominal crams bloody and sticky diarrhea. One can go for stool examination microscopically. Laboratory findings are like H and O markers are found on the surface of those bacteria.

In younger children these E. coli bacteria break down RBC and thus leads to anemia and thus results to acute renal failure which results in hemolytic uremic syndrome . There are specific microscopic findings of HUS in stool of infected patient is O157H7. This syndrome characteristically leads use to a critically situation as the patient should hospitalized in ICU and should often have stroke to avoid such situation dialysis is carried out. Thus we can say that patient may die due to (E coli) infections.

Treatment and management for Escherichia coli infections

The infection E coli can treated by antibiotics cefexime group of antibiotics due to electrolyte imbalance ringer lactate solution and dextrose solution is injected. Dialysis is also carried out to the critical patient who goes in uremia.
