Front 1

used for many years as an all-purpose fixative that is appropriate for helminth eggs and larvae and for protozoan cysts, oocysts, and spores

Back 1

Formalin

Front 2

How many percent for preservation of protozoan cysts

Back 2

5% of formalin

Front 3

How many percent for recommendation helminth eggs and larvae

Back 3

10%

Front 4

- help maintain organism morphology, the formalin can be buffered with ___________.

Back 4

sodium phosphate buffers

Front 5

used with all common types of stools and aspirates; protozoa, eggs, and larvae can be diagnosed without further staining in temporary wet mounts, either made immediately after fixation or prepared several weeks later

Back 5

MIF / Merthiolate-Iodine-Formaldehyde

Front 6

- for wet preparations - good stain preservative for most kinds and stages of parasites found in feces

Back 6

MIF / Merthiolate-Iodine-Formaldehyde

Front 7

lends itself to the concentration technique, the permanent stained smear, and fecal immunoassays for Giardia and Cryptosporidium and has the advantage of not containing mercuric chloride

Back 7

SAF / Sodium Acetate-Acetic Acid-Formalin

Front 8

SAF / Sodium Acetate-Acetic Acid-Formalin lends itself to the concentration technique, the permanent stained smear, and fecal immunoassays for __________ and ___________ and has the advantage of not containing mercuric chloride

Back 8

Giardia and Cryptosporidium

Front 9

considered to be a "softer" fixative than mercuric chloride

Back 9

SAF / Sodium Acetate-Acetic Acid-Formalin

Front 10

organism morphology is not quite as sharp after permanent staining as that of organisms originally fixed in solutions containing mercuric chloride

Back 10

SAF / Sodium Acetate-Acetic Acid-Formalin

Front 11

designed to be used with fresh stool specimens or samples from the intestinal mucosal surfac

Back 11

Schaudinn’s Fluid

provides excellent preservation of protozoan trophozoites and cysts

Back 12

Schaudinn’s Fluid

Front 13

Schaudinn’s Fluid provides excellent preservation of _____________ and __________.

Back 13

protozoan trophozoites and cysts

Front 14

not generally recommended for use in concentration procedures

Back 14

Schaudinn’s Fluid

Front 15

a plastic resin that is normally incorporated into Schaudinn's fixative serves as an adhesive for the stool material

Back 15
