The first edition (1980) of this well-received atlas was reviewed by D. L. DeGiusti in this Journal (Volume 30, No. 4, p. 906, 1981). The organization and notable features of that edition were pointed out in that review. The second edition incorporates some of the criticisms or advice, and the area of coverage has been expanded by adding eight more beautifully reproduced color plates including four malaria parasites, three Babesia spp., and Entamoeba polecki. Thus, this edition now covers all of the important endoparasites of humans. With some minor exceptions (e.g., epimastigotes of Trypanosoma cruzi and promastigotes of Leishmania, etc.) most photomicrographs and their reproduction are outstanding, making this atlas one of the best available for students, teachers, laboratory technicians, pathologists, and researchers dealing with human parasites.
