Who has encountered in analyses (in smear on stool culture) found chains of coli, enterococci fecal staphylococcus epidermidis, what is it generally harmful? How to treat it? Doctors say antibiotics but from antibiotics this thing can also be due to disruption of the microbiome. Already was a course of antibiotics from Pelonifrit (cystitis). and again...? To drink them like that I don't want to.
