@Izzie,
Roberta and Izzie, I get the use of the antibiotics, but I also don't.
Being an olden days lab tech, degree in microbiology, we ran plates, ran tests, tested colonies on individual plates with antibio tabs. It didn't take that long, you could tell early.
I'm against a lot of anti bio use as something to throw at congestion. It's like the dummies won.
Of course I'm for them when applicable.
But my take is that that part of pharma is spatial in the wrong way at the same time it can be debilitating to patients.
