Looking for Suggestions: QR and QM

I'm enough of a science geek that I only need these two to finish off the Q categories. Any suggestions, for a layperson who doesn't have a biology background but isn't scared of technical stuff? (I'd prefer to avoid scaremongering about how We're All Gonna Die from Disease X for QR (Microbiology).)

For QR you might be able to go with book about a microbiologist. My QR is a book about Pasteur.

The Life that Lives on Man by Michael Andrews is on my wishlist, and it's a QR book. It might be a little gross, but it doesn't look like a scaremongering book.

Thanks for the suggestions; I decided to put The Outer Reaches of Life by John R. Postgate on my wishlist -- I'm interested in extremophiles and in astrobiology so it seemed like a good fit.

There's a hillarious one called A Field Guide to Germs that I recommend for QR. For QM, I'd suggest Body of Work: Meditations on Mortality from the Human Anatomy lab. Both are good reads that are general enough to interest the non-biologist, not too gross, and still full enough to teach you things.

I finally found a readable-looking QM (it looks like most people who have that on their lists have Gray's Anatomy or similar, which I can't imagine actually *reading*:

Your Inner Fish was on the new book display table at my local bookstore this weekend. I didn't buy it -- it looks a little lightweight -- but it went on my wishlist as a "wait for the paperback".

I didn't even think about that one, but then, I assumed it was QH. We have it here in the library, so I may have to add it to my TBR pile.
