“Is there a specific treatment for E-coli?”

It depends where you get the infection with E. coli. If you have, for example, urinary tract infection, or E. coli invading the blood stream, then different po or iv antibiotics based on the severity of infection is appropriate. You don’t treat E. coli in the stool in the patients with diarrhea since most of them are self limited. E. coli responds to many antibiotics such as sulfa drugs, second and third generations of penicillin including Cefaten or Rocephin, as well as Cipro.

Yes, antibiotics that target gram negative bacilli. There are many such antibiotics, but they are only given during acute infection with E coli.

Depends on which e.coli you have. Most of them are self-limited meaning they go away on their own without treatment.

There are different strains of E. Coli and they’re treated differently. Why don’t you read up on this, since there’s so much to learn about it.
