question: my 3 month old son has a stomach infection.  We got a culture done for his stool and the organism present is Escherichia Coli.  His stools are very watery and Dark green and has a lot of Mucas. We gave him Walamycin ( 5 ml thrice a day for 5 days) and Neutrolin B ( 2.5 ml twice a day for 7 days). However, his stool is still dark green and watery.  What treatment should be given to him.  The stool is not smelly and he is exclusively breast fed.
