Q

. Female mosquitoes need animal’s hemoglobin to produce their eggs and generally, they feed at night, between

A

4PM - 4AM

night-biters

18
Q

According to the Department of Health (DOH) in 2019, endemic places are as follows:

A

Palawan (approximately 90% of cases), Sulu provinces, Mindoro Occidental, and Sultan Kudarat.

19
Q

dormant form, which is present only in Plasmodium vivax and P. ovale

A

Hypnozoite (H)

20
Q

Hypnozoite is only present in?

A

P. ovale and vivax

21
Q

What plasmodiums (2) have both primary and secondary exo-erythrocytic merozoites (EEM)

A

Ovale and vivax

22
Q

These plasmodium have simply merozoites only.

A

P. falciparum and P. malariae

24
Q

already in the blood stream, have a short life span, just like sporozoites, because they are obligate intracellular parasites, thus, should be able to find the next host cells, the red blood cells.

A

Merozoites

25
How is it possible for merozoites to invade rbcs?
the RBC has a receptor for merozoites
26
Plasmodium that prefer to invade young RBC including reticulocytes
vivax and ovale
27
prefers old or senescent RBC
Plasmodium malariae
28
infects RBC regardless of maturity or age
P. falciparum
29
Full entry of the merozoite inside the RBC. The parasite, inside the host RBC, is called?
young trophozoite
29
Young trophozoite, with a chromatin dot and thin ring of cytoplasm thus, also referred as?
ring form
30
he parasite, as it grows, utilizes what for its nourishment?
hgb through through acid digestion resulting to splitting of heme (with iron) from the globin fractions
31
serves as food for the parasite
globin
32
converted to hemozoin or the malarial pigment, which may begin to appear on the cytoplasm of the parasite during this stage of development (growing tropho)
heme
33
It causes the red blood cell to have fimbriations or become oval-shaped and these changes increase as the parasite matures
P. ovale
34
host red blood cell may become bigger than non-infected ones
Plasmodium vivax
35
This plasmodium has red blood cells do not necessarily change their sizes
P. falciparum and P. malariae
36
The membrane of the host RBC will also change resulting to formation of knobs, which are referred as?
stippling
37
The stippling are named based on the species such as
* Schuffner's dot = vivax * Zeinmman's dot = malariae * James' dots = ovale * Christopher dots, Maurer's cleft or Garnham bodies = falciparum
38
Each species has a particular period to complete the ES cycle, such as: P. vivax and ovale
48hrs
39
Each species has a particular period to complete the ES cycle, such as: P. malariae
72 hours
40
Each species has a particular period to complete the ES cycle, such as: P. falciparum
36-48 hours
