title: Diagnostic clinical parasitology: IV. Identification of the blood parasites?
abstract: This is the fourth article in a series of articles entitled "Diagnostic Clinical Parasitology" and contains information on the recovery and identification of human blood parasites. The organisms covered include those that cause the diseases malaria, babesiosis, leishmaniasis, and trypanosomiasis. Some of the filarial worms, which can be considered "blood parasites," have been discussed in the third article in the series, "Identification of the Helminths." Although some of these organisms may rarely be encountered in the laboratory in clinical specimens, they will probably have to be identified in proficiency testing specimens, some of which may not always be representative of patient clinical material. The differences between potential organism recovery from patients coming from endemic areas and from those individuals who become infected with no prior exposure to the organism will also be emphasized. Often, for a number of different reasons, organism recovery and subsequent identification may be more difficult than the textbook imply. It is very important for the technologist to recognize this fact, particularly when dealing with a possibly fatal infection, ie, Plasmodium falciparum.
