The book is extensively comprehensive and is concentrated on a single pathogen (Aspergillus fumigatus). It can provide valuable prospective with detailed information for all clinicians who need to know how to diagnose and treat the wide spectrum of diseases caused by A. fumigatus. In addition, to fully understand the disease, the basic properties of the fungus including its environmental habitant, life cycle and virulence factors are provided. For basic scientists who study A. fumigatus, an understanding of the clinical manifestations of aspergillosis can guide their studies in a direction that is relevant to human health. Furthermore, veterinary medicine on aspergillosis especially with high emphasize on birds is an interesting chapter for veterinarians.
