26
Comprised of a plastic powder that act as an adhesive for stool specimen when preparing slide for staining.
POLYVINYL ALCOHOL
27
* Can be sued for performing conc techniques and permanent stained smear. * Only requires single vial and it is mercury free
SODIUM ACETATE FORMALIN
28
* Free of formalin and mercury * Can be sued for conc techniques and permanent stained smears.
ALTERNATIVE SINGLE-VIAL SYSTEM
29
Diagnostic stages of parasites detected microscopically are measured in units known as ??
MICRONS
30
Also known as direct well mount.
DIRECT WET PREPARATION
31
* May be made to enhance the detail of the protozoan cysts. * Lugol’s or D’Antoni’s formula (drop of iodine) * It destroy the TROPHOZOITES stages of protozoan.
DIRECT WET IODINE PREPARATION
32
clearing solution in KATO THICK SMEAR
GLYCERINE
33
used to give color to the cellophane in order to give a pale green bg to the eggs and to minimize the brightness of the microscopic field
MALACHITE GREEN
34
- Useful in detecting eggs with thick shells such as Ascaris and Trichuris. * Not eggs with thin shells (hookworm)
KATO-THICK SMEAR
35
Reagents: o 40% HCl o Ether
ACID ETHER CONC TECHNIQUE
36
* Most widely used sedimentation techniique. * Based on specific gravity
FROMALIN-ETHY ACETATE SEDIMENTATION PROCEDURE
37
The direct wet preparation can be eliminated from the O&P examination if the specimen is received in fixative. TRU OR FOLZ
TRUE
38
Useul for the recovery of both helminth eggs and protozoan cysts. * Makes use of 10% formalin which is all purpose fixative
FORMALIN ETHER CONCENTRATION
39
Zinc sulfate with a specific gravity of ???
1.18 to 1.20
40
* Is considered as the BEST for the recovery of coccidian oocysts, mainly Cryptosporidium, Cyclospora and Isospora.
SHEATHER’S SIGAR FLOATION
41
Boiled sugar solution preserved with phenol is used in this method.
SHEATHER’S SIGAR FLOATION
42
* Time-consuming * Excellent morphology of the intestinal protozoa.
IRON HEMATOXYLIN
43
* Most widely used permanent stain * It uses reagents with a relatively long shelf life and the procedure is easy to perform
WHEATLY TRICHOLME
44
* Use of a saturated table salt solution.
BRINE FLOTATION
45
* Positive stools are mixed with moistened soil or granulated charcoal. BAERMANN TECHNIQUE
COPRO CULTURE
46
Consistency of the stool is the main determinant for the sensitivity of this technique. Used for assessing the intensity of infection in Schistosomiasis and common soil transmitted helminthiases
KATO KATZA METHOD
47
STOOL DILUENT IN STOLL EGG COUNT IS
SODIUM HYDROXIDE
48
* Is the specimen of choice for the detection of Enteriobius vermicularis (pinworm) eggs. * Otherwise known as the Graham technique
CELLOPHANE TAPE PREPARATION

51
most useful in species identification of malarial parasites.
THIN SMEARS
52
used in the demonstration of microfilariae and rapid diagnosis of malarial infection.
THICK SMEARS
53
o Considered the preferred stain because it allows for the detection of parasite detail necessary for species identification o May be prepared from powder or may be commercially purchased a conc stock solution.
GIEMSA STAIN
54
Makes use of a capillary tube which is precoated with acridine orange and potassium oxalate.
