Detailed Answer:

Hello,
Thanks for choosing HealthcareMagic for your query.
Have gone through your details and i appreciate your concerns.

Escherichia coli bacteria normally live in the intestines of human.Most E. coli are harmless and actually are an important part of a healthy human intestinal tract. Only some E. coli are pathogenic, meaning they can cause either diarrhea or illness outside of the intestinal tract.Most people recover within 6 to 8 days, but it can be life-threatening in people with a weakened immune system.Most strains of E. coli are harmless, but some produce a toxin that makes humans sick.
The group of E. coli that includes 0157:H7 produces a potent toxin called Shiga. This toxin can harm the lining of the small intestine.
So its not like every strain of ecoli is dangerous.

Yes probiotics would definitely help however antibiotics should be used for 5-7 days initially.Our body has its own enviroment called gut flora..Gut flora is the complex community of microorganisms that live in the digestive tracts of humans. The intestinal microflora is a complex ecosystem containing over 400 bacterial species. The flora is sparse in the stomach and upper intestine, but luxuriant in the lower bowel.Long term infection with yoxic strain of e.Coli can destroys this flora and can lead to various problems with digestive system like indigestion,abdominal pain,belching, bloating and increased gas formation loose motion or constipation.These symptoms may vary from person to person.Probiotic mechanisms of action include enhancement of the epithelial barrier, increased adhesion to intestinal mucosa, and concomitant inhibition of pathogen adhesion production of anti-microorganism substances and modulation of the immune system.In LAY MANS language it contain a lot of bacteria's which forms a part of normal gut flora.

Hope i was helpful.
Thanks!
