The major histocompatibility complex (MHC) is one of the most interesting and intriguing genetic systems, and continues to amaze geneticists, biochemists and particularly, immunologists and ...pathologists. The latest achievements on the structure and function of MHC genes and their products were discussed at a recent workshop.*
After discussing the classification of the Actinomycetales, the authors give a detailed description of the epidemiology and particularly of the clinical features of cutaneous diseases induced by ...genera such as Actinomyces, Norcardia and Streptomyces. Histopathological and immunological studies, together with laboratory and differential diagnostics, are also examined. In the last section, present therapeutic treatments are briefly outlined.
