Match the following with their respective characteristics in parasitology samples:

Plasmodium spp. stages = Resemblance: Human white blood cells Strongyloides stercoralis worm = Size range: 8-65 m, Average size: 12-25 m Hookworm filariform larvae = Nucleus: 2–4 segments connected by narrow, short chromatin bands; 15um Vegetable Cells = Exhibits a smooth cytoplasm; does not contain inclusions

Match the following confusers/artifacts with their descriptions:

Human Cell Confusers = Resemblance: Polymorphonuclears Plant Origin Confusers = Contains cytoplasmic inclusions like ingested red blood cells, and other fecal debris Yeast, Fungal & Algal material Confusers = These are remnants of ciliated epithelial cells that may be seen from sputum and stool samples Pollen Grains = May be confused with ciliates and flagellates

Match the following with their respective sizes in parasitology samples:

Plasmodium spp. stages = 12-18um Strongyloides stercoralis worm = 8-65 m Hookworm filariform larvae = 15um Pollen Grains = Average size: 12-25 m

Match the following descriptions with the correct item:

Vegetable Cells = Interior structures are unorganized and often appears to consist primarily of vacuoles; average size: up to 150 um Pollen Grain = Nonuniform cell wall; no notable internal structure Hookworm filariform larvae = Do not have head or tail regions; ladder-like appearance that consists of a series of rungs that are spaced closely together Strongyloides stercoralis worm = Characterized by the presence of budding Signup and view all the answers

Match the following items with their distinguishing characteristic:

Match the following items with their resemblance:

Pollen Grain = Bee pollen; absence of internal structure; unsymmetrical cell wall Strongyloides stercoralis worm = May resemble trematode; possible contamination of fecal sample Hookworm filariform larvae = Plant Material Resemblance: Ascaris lumbricoides ova Vegetable Cells = May be confused with helminth ova Signup and view all the answers

Match the following items with their resemblance:

Histoplasma capsulatum = Resemblance: Leishmania donovani bodies Pollen Grain = Yeast, Fungal & Algal material Budding Yeast Resemblance: Entamoeba hartmanni cyst Vegetable Cells = Psorospermium haeckelii may be confused with helminth ova Strongyloides stercoralis worm = Characteristically distinguished by the presence of budding Signup and view all the answers

Match the following descriptions with the correct organism or material:

Exhibits 'ring' structure = Malarial Ring Form Clumped or fused platelets in various shades of purple = Mature Schizonts Does not absorb iodine stain; no internal structures, buccal cavity = Strongyloides stercoralis worm Stain deposition on the surface of uninfected RBCs = Stain Precipitates Signup and view all the answers

Match the following with their resemblance or characteristics:

Root Hairs Resemblance = Plant Material Platelet on RBC surface revealing different shades of purple staining color = Howell-Jolly Body May be confused with spirochetes; anticoagulated blood sample left at room temperature = Exflagellation of Plasmodium vivax microgametocytes Pollen Grains & Resemblance = Taenia spp. Signup and view all the answers
