Yes.
Yes, alcohol can effectively kill E. coli bacteria.
Yes
Yes, salt can effectively kill E. coli bacteria by dehydrating them and disrupting their cellular functions.
There are some strains of E-coli for which there is no current antibiotic that is effective however chlorine bleach will still work on contaminated surfaces.
No. Go to the doctor.
Chlorine rapidly kills E coli bacteria. At a concentration of 1 part per million (the minimum level recommended for swimming pools), chlorine kills E coli in less than one minute. At 200 parts per million (about one tablespoon of household bleach in a gallon of water) the kill time would be less than a second. See the Centers for Disease Control and Prevention website: http://www.cdc.gov/healthyswimming/chlorine_timetable.htm
You do not know if a given sample of hamburger meat contains e coli, but you do know that if e coli is present, you can kill it by proper cooking; if the meat is undercooked, it may have e coli which will survive the inadequate cooking process and may cause food poisoning.
Chlorine in water disrupts the cell membrane and enzymes of E. coli, leading to cell death. It effectively prevents E. coli bacteria from reproducing and causing infection.
Escherichia coli
Ammonia is an effective disinfectant because it is known to kill harmful bacteria such as E. coli, salmonella and staphylococcus. Ammonia, or bleach as it is more commonly known, is widely available in supermarkets and home and garden stores.
Escherichia coli
To kill E.coli, antibiotics destroy its molecular coating, which allows the body's immune system to kill the bacteria.
