Antibiotic use certainly *could have* a detrimental effect on
beneficial micro-organisms. However, no one has shown that it does.
There certainly is no evidence that formic acid does so. Furthermore,
the bees themselves carry beneficial bacteria in their guts, so the
colony is continually being re-inoculated with the micro-organisms.
This is what makes infections so difficult to treat.
As a matter of fact, formic seems to have no effect on deformed wing virus:

Our failure to demonstrate a reduction in virus prevalence is troubling in that it demonstrates that removal of mites in late summer does not have an immediate effect on virus levels in colonies and the viral infections in these colonies is at high levels entering winter when most varroa/virus colony loss occurs.
