What is Erythrocytic schizogony?
What is Erythrocytic schizogony?
Erythrocytic schizogony is a phase of malaria infection when the red blood cells become infected by the parasite. In the red blood cells, the parasite goes through the various stages of development and finally they develop into merozoites.
Where do Erythrocytic schizogony occurs?
The first, called exoerythrocytic schizogony, occurs in the liver and is initiated by the sporozoite. The resulting merozoites then invade erythrocytes and undergo repeated rounds of merogony called erythrocytic schizogony.
What is the erythrocytic stage of malaria?
Erythrocytic stage: A stage in the life cycle of the malaria parasite found in the red blood cells. Erythrocytic stage parasites cause the symptoms of malaria. Etiology: The cause or origin of a disease or disorder; the study of the factors that cause disease and of the method of their introduction into the host.
What initiates the Erythrocytic schizogony cycle in Plasmodium?
Once released, merozoites infect red blood cells (red) to initiate the intra- erythrocytic parasite cycle.
What is the meaning of Erythrocytic?
A type of blood cell that is made in the bone marrow and found in the blood. Erythrocytes contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body. Checking the number of erythrocytes in the blood is usually part of a complete blood cell (CBC) test.
What is pre erythrocytic stage?
The pre-erythrocytic stage or exo-erythrocytic cycle includes both the sporozoite invasion of the mammalian host and the liver-stage. This stage represents a bottleneck in the disease which is ideal to block progression to clinical malaria, through chemotherapeutic and immunoprophylactic interventions.
What is pre Erythrocytic?
The pre-erythrocytic (PE)-stage Plasmodium parasite is a metabolically highly active but symptomatically silent preparatory phase of the life cycle.
What happens in the exo erythrocytic cycle?
In the exoerythrocytic stage, sporozoites from the mosquito’s saliva asexually multiply for about 7–28 days in liver cells before differentiating into invasive merozoites which enter the bloodstream to initiate the erythrocytic phase.
What is EXO Erythrocytic?
Medical Definition of exoerythrocytic : occurring outside the red blood cells —used of stages of malaria parasites.
What is the other name of WBC?
White blood cells, also known as leukocytes, are responsible for protecting your body from infection. As part of your immune system, white blood cells circulate in your blood and respond to injury or illness.
What is a hepatic Schizont?
hepatic schizont, the multinucleate form of the parasite that develops in hepatic cells from the sporozoite by asexual reproduction (schizogony) with incomplete cytokineses. This form of the parasite is also found in host erythrocytes (see erythrocytic schizont).
What is pre-erythrocytic stage?
What is EXO-Erythrocytic?
What happens in the exo-erythrocytic cycle?
What is the process of erythropoiesis?
Erythropoiesis (from Greek ‘erythro’ meaning “red” and ‘poiesis’ meaning “to make”) is the process which produces red blood cells (erythrocytes), which is the development from erythropoietic stem cell to mature red blood cell.
What is pre-erythrocyte schizogony?
pre-erythrocyte schizogony this phase of malaria occurs after the introduction of sporozoites, the infective form of the parasite, through the skin by the Anopheles mosquito. In this phase the patient is asymptomatic and the patient is not infective.
What is schizogony?
schizogony [skĭ-zog´ah-ne] the asexual reproduction of a sporozoiteby multiple fission within the body of the host, giving rise to merozoites, as in malaria. adj., adjschizogon´ic.

What causes erythrocyte differentiation to fail?
Erythrocyte differentiation. By the reticulocyte stage, the cell has extruded its nucleus, but is still capable of producing hemoglobin. Essential for the maturation of red blood cells are Vitamin B12 (cobalamin) and Vitamin B9 (Folic acid). Lack of either causes maturation failure in the process of erythropoiesis,…
