My daughter is 46 days old . During 3 rd week 2 times she passed white stool. So we took stool test and confirmed it be bacteria so we took taxim o . Last week we Took stool report again. It shows ecoli and mucous .she is doing adequate weight gains ,active and there is no other symptoms. Now the culture test shows ecoli resistant to Ceftraxione and doctor advised for Amikacin IV. Should we need to give Amikacin since there is no other symptoms except for mucous in stool
