>>13673292Yes, the wider the spectrum they cover the more they kill. That's one of threasons why physicians/pharmacists switch from "kill all" agent to a percise one once a microbe is identified.
The problem is, gut microbes are opportunistics, which means if some types die others will grow resulting in a secondary infection.
Got biome is recoverable most of the time by proper antibiotics to to stop the secondary infection, an rebalancing the proportion between the different types by using probiotics, food... (and sometimes, itreal shit from a healthy relative in extremely severe cases)
