Hey I took Microbiology, but I'm not sure if my textbook is slightly different. The author is Tortora and its an introduction Microbiology book. Are you taking the class with Dr. Mascio? because that is who I took it with. If so I would email him and ask if the book that I have would suffice for the class. I would think material in my book would be the same to what you will cover in class. Also I have the laboratory book (Benson's Microbiological Applications Manual) if interested.
Get back to me as soon as you can so I hold on to them for you.
