Parasites with no obvious structures for the purpose of motility

Sporozoa

1

6 stages of the life cycle of Plasmodium spp.

- ring forms (early trophozoite)
- developing trophozoites
- immature schizonts
- mature schizonts
- microgametocytes
- macrogametocytes

2

Stage of Plasmodium parasites following invasion into a previously healthy RBC

Ring form (early trophozoite)

3

Stage of Plasmodium where there is an emergence of the fully developed asexual sporozoa trophozoite

Mature schizont

4

Fully developed stage of the asexual sporozoa trophozoite

Merozoites

5

General shape of microgametocyte

Roundish

6

General shape of macrogametocytes

Round to oval

7

Mosquito genus responsible for the transmission of malaria to humans via blood meal

Anopheles

8

Infective stage of plasmodium transferred by Anopheles mosquito

Sporozoites

9

After entrance to the body, where are the sporozoites carried to by the peripheral blood?

Parenchymal cells of the liver

10

Asexual multiplication

Schizogony

11

Where does schizogony occur?

Parenchymal cells of the liver

12

Type of reproduction outside the RBCs

Exoerythrocytic cycle

13

Type of reproduction involving RBCs

Erythrocytic cycle

14

Phase of plasmodia where they feed on hemoglobin and pass through their 6 morphologic forms

Asexual phase

15

Dormant Plasmodium-infected liver cells

Hypnozoites/Cryptozoites

16

2 plasmodia that may exhibit hypnozoites

- Plasmodium vivax
- Plasmodium ovale

17

A relapse infection of malaria

Recrudescence

18

Place where the sexual phase of plasmodia occur

Stomach of mosquito

19

Forms when the male and female plasmodia gametocytes unite in the stomach of the mosquito

Ookinete (zygote)

20

An encysted zygote (ookinete)

Oocyst

21

Type of malaria that occurs when uninfected patients recieve blood tainted with malaria collected from an infected donor

Transfusion malaria

22

Type of malaria that is spread through the sharing of needles and syringes

Mainline malaria

23

Type of malaria that results from the passing of the parasite from mother to child

Congenital malaria

24

Stain of choice for peripheral blood films for laboratory diagnosis of malaria

Giemsa

25

Type of blood smear for screening slides

Thick blood smears

26

Type of blood smear for differentiating Plasmodium spp.

Thin blood smears

27

2 Plasmodium spp. that may infect an individual at the same time

- P. vivax
- P. falciparum

28

Best time to collect blood for Plasmodium parasites

During paroxysms

29

Methodology that helps to rule out malaria in patients suffering from a fever of unknown origin

Serologic testing
