Abstract:

This section talks about the diagnostic characteristics for organisms. Characteristics (including size, motility, nucleus number and visibility) of intestinal protozoa such as amebae, flagellates, ciliates, coccidia characteristics of trophozoites, cysts of each species are given separately. Comparisons of various diagnostic techniques such as light microscopy, routine histology, electron microscopy, serologic antibody detection for identification are provided. Comparison of , spp., , and have also been provided in the section. Normal life spans and characteristics of the most common intestinal nematodes, tissue cestodes, liver and lung trematodes, human paragonimiasis, blood trematodes, are listed in the tables. Potential problems using EDTA anticoagulant for the preparation of thin and thick blood films are listed in detail. Features of human leishmanial infections and characteristics of American trypanosomiasis are also provided in a tabular form. Key characteristics of helminthes, blood parasites, rapid diagnostic procedures are listed separately in tables.

Intestinal amebae of humans. Top row: Trophozoites. shown with ingested RBCs. This is the only microscopic finding allowing differentiation of pathogenic from nonpathogenic ; all cysts and trophozoites containing no RBCs must be reported as . An ameboid form of is rarely seen and difficult to identify. Middle row: Cysts. For the central-body form is depicted. Bottom row: Trophozoite nuclei, shown in relative proportion. (From A. L.
