A hunter prepared dried jerky from fresh bear meat and provided some to a group of friends. Most developed moderate to severe abdominal pain, nausea, and fatigue within 48 hours. Some of the bear meat was submitted for laboratory testing.
The mother of a four-year-old autistic boy found a worm in her son’s stool while changing his diaper. The family lives on a farm in rural Iowa. The worm and a stool specimen were examined by the Iowa State Hygienic Laboratory, and the images sent to the DPDx Team for confirmation/identification of one or more parasites.
Welcome to DPDx, a Web site developed and maintained by CDC's Division of Parasitic Diseases and Malaria (DPDM). DPDx uses the Internet to strengthen diagnosis of parasitic diseases, both in the United States and abroad. This interactive and rapid exchange of information, 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 (please, kindly cite the source). Copyrighted material includes the 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 laboratory and other health professionals can ask questions and/or send digital images of specimens for expedited review and consultation with DPDx 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, or make comments or suggestions, please contact the DPDx team.
