As far as I know they are quite good at detecting, only finding the
"antidote" before it is too late can be a problem. However antibiotics
usually can help quite a lot.
And even if we were not immune to alien bacteria, would we be able to spot
it? Likely there are more Earthly bacteria that kill people than Space bacteria.

Well, that's why I didn't mention it the other discussion :)

Which "cultures with magical technology" do you mean. I can't recall when WE
encountered them before. True other cultures did, but I thought they usually
believed in magic.

Why then contact us and give us the data? Just for the fun to see what happens?

What good is destroying your test subject if your only example?
