This is one of my best investments thus far in medical school. I always thought microbiology was a subject of rote memorization, that it doesn't lend itself well to anecdotes and pictorials. But this book completely jumped that hurdle and did what I believe more books should do. The pictures, mnemonics, stories, etc. are corny, humorous, fun, and above all, helpful. Some of them seem ridiculously far-fetched, but surprisingly they stick with you. Yes, it doesn't tailor to everyone's learning style and you may not want to re-read through a 400pg book while studying for the USMLE, but before you go to the flashcards give this book a try; at its price it's well worth the investment. Thanks to the authors for this, and my only suggestion for future editions is MORE PICTURES!
