Early diagnosis of parasitic diseases, especially of the opportunistic infections, is gaining importance daily and pathologists now have the chance to make rapid diagnoses of these disorders by examining tissues and body fluids. Though parasitic infections and infestations occur mainly in subtropical and tropical areas, they are increasingly imported into other areas, where the pathologist must be able to recognize them. This new full-colour atlas, containing over 500 photographs, many diagrams and tables, with extensive references and index, concentrates on histology, differential diagnosis and on the structure of parasitic elements such as eggs, larvae and adult worms, in and outside tissues. The atlas should be useful as a bench manual for the practising pathologists to keep by the microscope, as well as for physicians, surgeons, dermatologists and pathologists in training, and all those who are concerned with parasitic infections.
