a neurological poison |
|
Fecal concentrations
|
used to concentrate parasitic forms in fecal samples. based on the fact that parasites will float in Zinc-Sulfate solutions of high osmolarity and specimens can be collected onto a glass slide and observed with a LM.
|
|
KOH preps
|
quick and inexpensive to view microscopic arthropods.
causes most tissue elements to dissolve leaving parasite forms that retain their shape and color and can be observed with LM. (sarcoptes mite) |
|
Giemsa stain
|
used when intracellular structures are to be examined. stains tissue and blood cells showing blue-colored intracellular parasites, sometimes with a halo around them
(leishmania amastigotes) |
|
trichrome stain
|
standard procedure used for staining parasites in fecal material. stains protozoans cells pink with blue-green organelles
(entamoeba histolytica trophozoite |
|
Wrights Stain
|
used to id cell types in blood smears. stains leucocytes and erythrocytes as wells as protozoans or micofilaria in blood smears.
(babesia, trophozoites?) |
|
acid fast stain
|
used to find and id small protozoans in fecal smears.
stains cells pink with blue background making them easy to find. |
|
protoplasm
|
differentiated into a nucleus, cytoplasm, and organelles.
|
|
function of protozoan ectoplasm vs endoplasm
|
ectoplasm: movement, ingestion of food, excretion, respiration and protection.
