Stool report of you baby shows bacterial infection of the gastrointestinal tract. Don't worry it is curable.
Doctor has already prescribed Ximacef, which is a broad spectrum antibiotic cefixime
Make sure that your baby is not dehydrated and get him examined by a Paediatrician.
Always take care of hygeine of the baby as at this age babies tries to put everything in mouth resulting in infection.
Always give your baby pure filtered water to drink and vaccinate the baby at appropiate time as it prevents many infections.
I hope this is useful to you.
Thanks and take care.
