Hello, Thank you for contacting HCM I understand your concern, I am Dr Arun Tank, Infectious Disease Specialist answering your query. E coli can be treated and has no effect on the baby. But CMV can have birth defect in the baby. CMV can cause retinitis and ear defect in resulting child. I advice you to take the cephalexin 500 mg four times a day for four days for E. coli infection. For CMV you can take gancyclovir. But take all above medication under your doctors guidance. Some cases of CMV has serious defect in children I advice you should discuss this with your treating doctor. For UTI I advice you should take plenty of water as much as you can take. IT will flush out your residual bacteria. Please wash your hand frequently in day time as it can also transmits the bacteria to the urinary tract. Maintaining hygiene is also a important part as it can also treat you equally as other antibiotics do. You can ask for further queries here on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious Disease specialist We wish you a best health at health care magic.
