Abstract: A set of nine A-4 colour plates with 118 photomicrographs illustrating the appearance and diagnostic features of all the common intestinal helminths and protozoan parasites known to infect humans. Produced in a robust plasticized format, the plates can be used as either a guide for laboratory and field workers in endemic countries or a teaching aid for students and trainees. The aim is to help the microscopist ascertain the presence of parasites in faeces, whether they be minute protozoan cysts or large helminth eggs, and to identify them correctly. With this goal in mind, the bench aids include pertinent laboratory instructions as well as high-quality images. The photomicrographs illustrate diagnostic features of each of the parasites as they appear in different preparations and at different magnifications. Each photomicrograph is produced with a measuring bar and accompanied by a short explanatory legend, which draws attention to distinctive features that help confirm diagnosis. Helminth eggs are illustrated in the first 36 photomicrographs, which show the diagnostic stages of the most common helminths, including nematodes, cestodes, schistosomes, and other trematodes. The remaining photomicrographs offer advice on the more difficult task of detecting and identifying intestinal protozoan trophozoites and cysts. Relevant laboratory techniques are described on the reverse side of the plates. Additional laboratory aids include dichotomous keys for the identification of amoebic trophozoites, trophozoites of intestinal flagellates, and cysts of amoebae and flagellates
