This Web site from the Centers for Disease Control and Prevention's Division of Parasitic Diseases has a goal of "using the internet to strengthen diagnosis of parasitic diseases." The site provides information about the cause, life cycle, and treatment (among other things) for a number of parasites, listed in alphabetical order and categorized by location of residence. The image library contains a number of images for each parasite. Laboratory researchers and medical professionals may also benefit from the site's Diagnostic Assistance feature, where digital images and data about the parasite can be emailed to DPDx for diagnosis.
