Abstract:

There are a wide variety of less commonly encountered helminthic parasites, which may be nematodes, cestodes, or trematodes. The diseases caused by these parasites are interesting and demonstrate their highly evolved life cycles and the complex interactions with their hosts. These diseases range from subclinical, e.g., dipylidiasis, to possibly life-threatening, e.g., baylisascariasis. In many instances, the disease occurs only in a particular geographic area, which is largely determined by the biological ranges of the definitive and intermediate hosts. Dietary customs are also important in the prevalence of human disease, as many of these are associated with the ingestion of raw animal products. The treatment of these parasites varies depending on the infectious agent, but common preventive measures may significantly diminish the transmission of many of these parasitic diseases. These measures include the zoonotic control of parasitic disease in animal hosts and the vectors of transmission, washing of fruits and vegetables, access to clean drinking water, and thorough cooking of meats before consumption.
