If fever is used by the body to kill bacteria or viruses, does this not also damage the useful bacteria in the gut?

The temperature reached during a fever is not high enough to outright kill pathogens (or friendly bacteria) inside the body, so that's not the reason why this mechanism exists.

Science is still debating and conducting studies on the kind of effect that fever has during an infection. There is some evidence suggesting that several cells of the immune system (leucocytes and t-cells) move faster and multiply at a higher rate at higher body temperatures.
