Thanks for the query
Don't run behind stool reports, because all this can be present even in a healthy individual. If his bowel pattern is normal then this report doesn't suggests any infection. Some bacteria are normal habitats of our intestine and they are important for digestion and production of some vitamins
So I would suggest you to follow the advice of your doc if there is no other problem. But if still there is stomach upset
Then give him O2/ Ofal-M syp. 7.5 ml twice daily for 5 days.
I hope this answers your query well
Wish you and your family good health
