Hello. Thanks for using HCM.
The whole idea of avoiding overuse of antibiotics in wound infection
is not to cause more worsening of the wound by forming bacterias which are resistant to that antibiotic effect. I am sure you would have already got an antibiotic course during the surgery. Ecoli infection is related to the colon
resection since this strain of bacteria is more commonly found there. However on the other hand you should continue to monitor your temperature, low grade fever
is still not so alarming as high grade fever. You should also check for the skin and wound color, odor and if any pus discharge is present. If any of these signs are present you should immediately consult with your treating doctor, who can assess the wound.
Feel free for further queries.
