Book excerpt: Laboratory Handbook of Medical Mycology summarizes the concepts dealing with the laboratory aspects of medical mycology. The publication first offers information on basic terminology and classification, laboratory safety, and clinical specimens. Discussions focus on tissue, abscess, blood, bone marrow, and urine specimens, biological hazards, disinfection and sterilization, grounding of electrical equipment, waste disposal, asexual and sexual reproduction, and vegetative growth. The text then takes a look at mold and yeast identification, including fermentation, temperature studies, asci and ascospores, zygomycetes, cycloheximide resistance, and sporulation and sterile isolates. The manuscript ponders on susceptibility testing and bioassay procedures, culture collection, and quality control. Topics include proficiency evaluations, media and equipment control, depositing unusual isolates in major culture collections, reconstituting lyophilized cultures, bioassay to determine drug levels in body fluids, and in vitro susceptibility testing. The publication is a dependable source of data for laboratory technologists, microbiologists, and mycologists engaged in safely isolating and accurately identifying fungi of medical importance.
