Welcome to DPDx, a Web site developed and maintained by CDC’s Division of Parasitic Diseases (DPD).  Our goal is to use the Internet to strengthen diagnosis of parasitic diseases, both in the United States and abroad.  The interactive and rapid exchange of information permitted by the Internet, allied with already available diagnostic reference resources, will enhance our capacity to address the global problem of parasitic diseases.

For that purpose, DPDx offers two complementary functions:

• A Reference and Training function, in which all users can browse through concise reviews of parasites and parasitic diseases, including an image library and a review of recommended procedures for collecting, shipping, processing, and examining biologic specimens.  Most of the material is free of copyright and users are welcome to store and copy material in the public domain as they wish (please, kindly cite the source!).  Copyrighted material includes: life cycle images of Blastocystis and Pneumocystis, and electron micrograph images of Gnathostoma; if users are interested in publishing these items, they must obtain permission from the original copyright holder.
• A Diagnostic Assistance function, in which laboratorians and other health professionals desiring assistance in parasite identification can ask questions and/or send digital images of specimens for expedited review and consultation with DPD staff.  This assistance is free of charge.

Potential DPDx applications include:

• training and continuing education of laboratorians, using material collected by CDC or contributed by other institutions
• provision to health facilities worldwide of diagnostic assistance by CDC staff backed up when needed by experts from other institutions
• diagnostic quizzes for self-assessment of laboratorians’ skills
• informal, early detection of unusually clustered, atypical or emerging parasitic diseases

If you wish to:

• contribute diagnostic images or information of particular interest
• make comments or suggestions

PLEASE contact us!
