>>13933414Correct. The next step to fill in the gap actually requires knowledge on biology and lab equipment. You would need to isolate and culture cells from your mouth mucosae, isolate a known respiratory tract pathogen from your very own mouth, put them in a medium, and watch the magic. This can be made by any person with a bunsen burner or torch, a petri dish, an air filter, and agar that can contain the medium.
If you're not convinced, then you'll have to mark whatever adherence factor or antigen you suspect was responsible for the mucosae cell destruction, and watch in real time how it starts showing up out of proportion on both the bacterium and the cell. This is out of immediate reach for a person, but if you're as persistent as you sound, you'll find a way.
Funny thing is
>>13933408 is not too far off, but you're seeing things isolated from each other. Germs can actively destroy the cell, or cause inflammation or asphyxia which, in turn can enhance the germ's lethality. Except virii, though. Those will straight up destroy anything they infect if left to their own devices.
