Rezension

"There is no other current book that gives the details on experimental procedures that this one does…a very worthwhile acquisition for investigators working with fungi." (Doody's Health Services) "Will be very useful to many students and bench scientists wishing to expand their repertoire of practical skills in medical mycology." (Microbiology Today, March 2008) Medical Mycology is a useful guide for molecular, immunological, and cytological techniques that will provide useful to researchers and students alike.
