Firstly, I urge you to relax. Both the results are normal.
On stool routine, it is normal to find E. coli cysts. Her urinalysis
is also normal; pus cells of 4 to 5 are still fine.
Just give her plenty of fluids to drink, maintain good personal hygiene. Ask her to wash her hands frequently with a good antiseptic soap. Especially before eating any food or drinking.
She does not require any more treatment. She will be fine soon.
