Plate 8.1

Row 1: artifact, human macrophages (the artifact and human cells mimic intestinal amebae); row 2: artifacts tend to mimic intestinal amebae, possibly Entamoeba coli; row 3: artifact (Cyclospora cayetanensis oocyst), artifact (Cryptosporidium spp. oocyst), spores (Cryptosporidium spp. oocysts); row 4: amebic precysts (can be confused with artifacts), pale “organism” (appears to have a nucleus), epithelial cell (can mimic a larger protozoan like Balantidium coli).

Plate 8.2

Row 1: first two images are artifacts that mimic Ascaris lumbricoides eggs, third image is an artifact that mimics a hookworm egg; row 2: artifacts tend to mimic Trichuris trichiura eggs; row 3: first image is pollen (if turned correctly, can mimic Trichuris trichiura egg), next two images are artifacts (suggestive of Hymenolepis nana eggs); row 4: artifact (can be misidentified as Taenia egg), pollen (also mimics Taenia egg), artifacts (can mimic helminth eggs).

Plate 8.3

Row 1: threads (mimic small worms or helminth larvae), root hair (mimics Strongyloides stercoralis larva); row 2: root hair (mimics Strongyloides stercoralis larvae), artifact (mimics Diphyllobothrium latum egg), artifact (mimics helminth egg, possibly trematode egg with operculum missing); row 3: the first image is an artifact (mimics organism in blood), the next two images represent exflagellation of male Plasmodium gametocytes (can mimic spirochetes in blood); row 4: artifact (stain deposition can mimic Plasmodium spp.), flattened Plasmodium vivax trophozoite (shape can mimic crescent-shaped gametocyte of Plasmodium falciparum), immature Plasmodium falciparum gametocyte (may not be recognized as an actual parasite).

Plate 8.4

Row 1: artifacts (mimic Babesia spp.), Histoplasma capsulatum (mimics Leishmania donovani amastigotes), Gordius (can mimic actual parasitic worms); row 2: first two images are seeds (mimic helminth histologic sections), third image is thread in tissue (mimics microfilarial nematode); row 3: ciliated human cell (mimics “unknown” flagellate), human cells (can mimic protozoa or amebae), Charcot-Leyden crystal (related to breakdown products of eosinophils—may not be recognized); row 4: yeast (if budding is not recognized, can be misidentified as small protozoa or coccidia), Gram stain showing intracellular microsporidial spores (can be misidentified as bacteria), artifact that may be bacterial spores (may be misidentified as microsporidial spores).
