Term
What characteristics do members of the phylum Apicomplexa share?
Definition
All are parasitic, have Apical Complex at one end of the organism
Term
What is the function of each of the components of the apical complex?
Definition
Rhoptries and Mrinemes- secretory organelles host cell penetration
Conoid and Subpellicular microtubules – structural
Term
Worldwide, how many people are infected with and how many die from Plasmodium?
Definition
Approx.. half the world at risk. 216 *10^6 cases and 655000 deaths.
Term
What are the four species of Plasmodium which infect humans
Definition
1. Ovale 2. Malaria 3. faciparum
Term
Trace an overview of the life cycle of the Plasmodium parasite in the vertebrate and mosquito hosts.
Definition
Sporozoite transmission stage to the human bloodliverexoerethrocytic cycle multiplies prepatant time of development RBC erthrocytic cell multiply gametocyte transmission stage to mosquito stomach of mosquito hemocoel  glands
Term
What species of mosquito transmits malaria?
Definition
anopheles
Term
Is it the male or female mosquito?
Definition
Female
Term
What stage of the parasite is infective to humans?
Definition
sporozoite
Term
Why do sporozoites invade hepatocytes and no other cells?
Definition
circumprozoite protein cenable them to invade hepatocyte
Term
What is the exoerythrocytic cycle?
Definition
Metamorphoses into the trophzoite stage (feeding stage) it feeds on host cell cytoplasm. After approx 1 week- mature.

Metamorphoses into the trophzoite stage (feeding stage) it feeds on host cell cytoplasm. After approx 1 week- mature.

Begin Schizogony- asexual reproduction. Nuclear division. Numerous daughter nuclei.
=schizont
=cryptozite

Cytoplasm divides –meterozoites formed
Merozoites burst out of hepatocytes – initiate the erthrocytic cycle
Term
. How does the mosquito transmit the parasite to the human host
Definition
Probes skin for capillary, injects salivary gland secretions which prevent clotting. Sporozoites in her salivary glands gets ingested.
Term
Once the sporozoite invades the hepatocyte, it transforms into a
Definition
trophozoite
Term
This stage feeds for approximately one week and then undergoes a process of asexual reproduction known as
Definition
Schizagony
Term
What occurs in the two steps of this process?
Definition
Nuclear division, and cytoplasmic division
Term
What is the end product of this reproduction
Definition
merozoites
Term
This stage leaves the liver, enters the blood and initiates which cycle
Definition
Erythrocytic cycle
Term
What is the function of MSP-1
Definition
It’s the merozoite surface protein-1. Interacts with and binds to proteins on RBC surface.
Term
How does the apical complex function during the invasion of an RBC?
Definition
Secretions from apical complex help the merozoite push in
Term
How did the signet ring stage get its name?
Definition
Because of the large food vacuole within the troph.
Term
How did the signet ring stage get its name?
Definition
Because of the large food vacuole within the troph.
Term
What is hemozoin?
Definition
End product of parasite. Aids in digestion of hemoglobin.
Term
Does schizogony occur during the erythrocytic cycle
Definition
Yes, blood shizont
Term
What is released when an infected RBC ruptures?
Definition
Merozoites and parasitic wastes
Term
What does synchrony mean in a malaria infection?
Definition
merozoites develop at the same time.
Term
How is this related to the fevers associated with infection?
Definition
massive release of merozoites of metozoites and wastes stimulates host response—Fevers and chills.
Term
What is the fate of micro- and macrogametocytes
Definition
Some merazoites enter RBCs and develop into macro and microgametocytes.
Term
What stage of Plasmodium is infective to the vector?
Definition
Gametocytes reeased in anopheles stomach
Term
What happens to the macrogametocyte in the vector
Definition
Nucleus shifts and now known as microgamete (female).
Term
Name and explain the process which the microgametocyte undergoes in the vector.
Definition
Exflagellation in mosquito stomach- nucleus divides into 8 daughter nuclei. Each develops flagellum, cluster breaks apart and have 8 micrgametes (male). Stimulus for exflagellation is decrease in tem and increase in Ph.
Term
What two cells join during fertilization and what stage is produced
Definition
Microgamete and macrogamets
Term
Where does the ookinete go?
Definition
Penetrate stomach wall and g to hemocoel and attach
Term
How many sporozoites develop in one oocyst
Definition
more than 10,000
Term
How do the sporozoites get to the salivary glands
Definition
Break out of the oocyte when the sporoblast divides along with the nucleus and migrate to salivary glands.
Term
How does feeding behavior change in an infected mosquito?
Definition
Stimulates the mosquito to feed more frequently.

Definition
Nucleus shifts and now known as microgamete (female).
Term
Name and explain the process which the microgametocyte undergoes in the vector.
Definition
Exflagellation in mosquito stomach- nucleus divides into 8 daughter nuclei. Each develops flagellum, cluster breaks apart and have 8 micrgametes (male). Stimulus for exflagellation is decrease in tem and increase in Ph.

Penetrate stomach wall and g to hemocoel and attach
Term
How many sporozoites develop in one oocyst
Definition
more than 10,000
Term
How do the sporozoites get to the salivary glands
Definition
Break out of the oocyte when the sporoblast divides along with the nucleus and migrate to salivary glands.
Term
How does feeding behavior change in an infected mosquito?
Definition
Stimulates the mosquito to feed more frequently.

Term
What stage of the parasite is infective to humans?
Definition
sporozoite
Term
Why do sporozoites invade hepatocytes and no other cells?
Definition
circumprozoite protein cenable them to invade hepatocyte
Term
What is the exoerythrocytic cycle?
Definition
Metamorphoses into the trophzoite stage (feeding stage) it feeds on host cell cytoplasm. After approx 1 week- mature.

Metamorphoses into the trophzoite stage (feeding stage) it feeds on host cell cytoplasm. After approx 1 week- mature.

Begin Schizogony- asexual reproduction. Nuclear division. Numerous daughter nuclei.
=schizont
=cryptozite

Cytoplasm divides –meterozoites formed
Merozoites burst out of hepatocytes – initiate the erthrocytic cycle
Term
. How does the mosquito transmit the parasite to the human host
Definition
Probes skin for capillary, injects salivary gland secretions which prevent clotting. Sporozoites in her salivary glands gets ingested.
Term
Once the sporozoite invades the hepatocyte, it transforms into a

trophozoite
Term
This stage feeds for approximately one week and then undergoes a process of asexual reproduction known as

Erythrocytic cycle
Term

Definition
It’s the merozoite surface protein-1. Interacts with and binds to proteins on RBC surface.
Term
How does the apical complex function during the invasion of an RBC?
Definition
Secretions from apical complex help the merozoite push in
Term
How did the signet ring stage get its name?
Definition
Because of the large food vacuole within the troph.
