In today's global community, the new fifth edition of Ash and Orihel's Atlas of Human Parasitology is a must-have for parasitic identification. Coverage is complete, including well-recognised species of parasites as well as information on those less commonly encountered.

Authored by two of the most widely recognised and respected educators and researchers in the field, the new fifth edition features: new imaging throughout; quick morphologic keys; clinical images of infection; important diagnostic procedures; and expanded treatment of parasite-like artefacts and pseudoparasites culled from real-world cases.
