Mitogens in Immunobiology

publishing house. Much of what this reviewer said about the Genetics volume* applies to the present volume as well. The individual chapters are up to date (e.g., tobramycin and amikacin are discussed) and are, on the whole, very well written except that they contain an unusual number of misspellings. However, the topic of resistance has not been thoroughly covered-certain molecular aspects are still missing. The chapter on epidemiological typing seems out of place, and the amount of duplication between the chapters is considerable. The highly specialized character of the information in some chapters, e.g., those on sensitivity to ethylene diamine tetraacetic acid or on the ultrastructural relationships, makes it unlikely that the book will appeal to a wide readership. Medical microbiologists would probably be interested in only four out of the eight chapters (unless they work in the field), and the same obtains for non-medical microbiologists. I should think that specialists in the area already have the information needed. Therefore, the value of this volume lies chiefly in the compilation of data for those who are not experts on Pseudomonas aeruginosa. One hopes that the two volumes will be reorganized and supplemented so that they will appeal to more scientists when funds for new books have become scarce. *Yale J Biol Med 49:308-309, 1976 ALEXANDER VON GRAEVENITZ Department of Laboratory Medicine Yale University School of Medicine
