Protozoology: a Manual for Medical Men

THE preface of this book states very plainly that it is intended for medical men as distinct from research workers, and that on this account the arrangement of the groups differs from that usually adopted by zoologists. This precludes criticism from the purely zoological point of view. The authors state concisely most of the information about parasitic protozoa essential for the medical man, but it is a pity that in a book with this definite scope the disdussion of immunity and chemotherapy in trypanosomiasis should be so inadequate. A useful account of the pathology of the diseases caused by various protozoan parasites is given. The section on malaria is treated very fully and gives a good description of the conditions created by this organism. The authors have given some account of the more serious difficulties and pitfalls in the microscopic examination of blood and fæces, and there is a brief chapter on methods which will be valuable to clinicians working abroad.Protozoology: a Manual for Medical Men.By John Gordon Thomson Andrew Robertson.
