Serious salmonella infections marked by inflammation of the intestines are treated with this kind of medications. It is necessary to examine what antibiotics salmonella is resistant to. If the bacteria have developed resistance to some medicines, then they can’t be used in the treatment, because it can make the treatment more difficult.
