1

Zinc Sulfate

This flotation method uses this ingredient to float parasitic forms

2

Macroscopic Examination

Tapeworm proglottids may be first seen during this fecal examination

3

Microsporidia

The modified trichrome technique of Weber and Green is used to stain these parasites

4

Knott Technique

Method for concentrating Microfilariae in blood samples

5

Wheatley trichrome technique

Cytosplasm of E. histolytica trophozoites appears light blue-green or pink; Karyosomes of nuclei stain ruby red

6

Operculated eggs or heavy infertile Ascaris eggs

When a floatation method is used, sediment should be checked to find these eggs

7

Thick Smear

The proper technique used to find malaria parasites in human specimens

8

Strongyloses stercoralis

The agar plate culture is used to diagnose infection with this parasite

9

Cryptosporidium spp.

Modified Kinyoun Acid-fast Stain is used to visualize these parasites

10

Naegleria fowleri and Trachipleistophora hominis

Nasal discharge is examined to reveal this parasite

11

Microscopic Examination

A fecal concentration technique is part of this fecal procedure

12

Direct Wet Mount

Used for examining fresh liquid or very soft stool

13

Sedimentation Method

This concentration technique uses ethyl-acetate to remove fa

14

Kinyoun modified

Adding acid-fast components to this stain allows visualization of Cryptosporidium spp.

15

Cellophane Tape Test

Used to sample the patient's perianal region

16

Novy-MacNeal-Nicolle (NNN) medium

Leishmania spp. and Trypanosoma cruzi can be cultured using

17

Balamuth medium

Entamoeba histolytica, Naegleria fowleri, and Trichomonas vaginalis can be cultured in

18

Ocular micrometer

Used to determine the size differences of internal structures or whole organisms

19

Giemsa stain

Used to visualize blood-borne parasites

20

Flotation Methods

This concentrating solution having a final specific gravity of 1.18 is used in the
