Erythrocyte (Erythmcytic)

Erythmcytic is a term that is widely used in medicine to describe various processes associated with erythrocytes - red blood cells responsible for transporting oxygen throughout the body. However, in this context we will talk about the use of this term to describe the life cycle of the parasites that cause malaria.

Malaria is an infectious disease caused by parasites of the genus Plasmodium, transmitted through mosquito bites. Once in the bloodstream, parasites begin their life cycle, going through several stages of development, including stages that occur inside red blood cells.

When parasites enter the bloodstream, they begin to look for suitable red blood cells to reproduce. After they find a suitable red blood cell, they penetrate it and begin their development, which occurs in several stages.

The first stage of parasite development inside red blood cells is called terminal invasion. The parasite penetrates the red blood cell and begins to actively consume hemoglobin, a protein that is responsible for transporting oxygen. This process can lead to the destruction of the red blood cell and release of parasites into the bloodstream.

The next stage of parasite development is the trophozoite stage. At this stage, the parasite begins to actively divide inside the red blood cell, creating new parasites that can then infect new red blood cells.

Finally, at the last stage of development of parasites inside erythrocytes, they turn into a schizont, which contains many daughter cells - merozoites. These merozoites are then released into the bloodstream, ready to infect new red blood cells and continue the developmental cycle.

Thus, the term "erythmcytic" is used to describe all stages of the life cycle of the malaria parasite that occur within red blood cells. In comparison, the term "exoerythrocytic" describes the stages of parasite development that occur outside the red blood cells. These terms play an important role in understanding the mechanisms of malaria development and help in the development of new methods of treatment and prevention of this disease.



Red blood cell development is a stage in the life cycle of Plasmodium spp. in which the parasite exists inside human red blood cells. It passes immediately before and during penetration into the capillary. Unlike exoerythrocytes, erythrocyte trophozoites remain without the ability to further reproduce and transform into an adult form. They die soon after leaving the hematopoietic organ.

Development within and between red blood cells is a unique example of the parasite life cycle. Most other parasitic protists either prefer to travel in one or more hosts or remain in them for long periods before turning to the external environment. The uniqueness of erythrocytic development lies in its constant presence in the bloodstream of its host, as well as in the transformation of two generations of parasites within the cytoplasmic compartments of its own host cell. Such features explain the intercellular transmission of the microorganism between different populations and countries.



Malaria is an infectious disease caused by parasites of the genus Plasmodium. It is characterized by severe fever, anemia and complications that can be fatal. Knowledge of the life stage of the parasite is necessary to understand the mechanism of disease development and control.

The term "red blood cell" means that the parasites live inside the red blood cells. "Trophozoite" is the term for the stage of the parasite that is actively invading the cells of the host. The life cycle of the parasite begins with an infected cell, in which sporulated germ cells are formed. After fertilization of the cell, it enters the state of meroiglyphy - a stage when the separation of paired nuclei and triploid diploid metabolism occurs. At this stage, some of the trophozoites transform into ookinetes and leave the host organism to enter another host organism and continue the life cycle without the involvement of reproduction.

The erythrocyte stage of the parasite includes three stages: plasmodium gamont, nematodiagus and schizont. In "gamont plasmodium" the parasite is ready to reproduce by binary fission and produces male and female trophozoites. The parasite is in the nematode stage



The erythrocyte stages of the parasite pass inside red blood cells, where it multiplies and develops. The name "erythrocytes" came into use in science thanks to the botanist Augustinus Erythmatius, who discovered malarial mosquitoes - leeches.
