Trophozoite

Trophozoites are the stage of development of malaria parasites from merozoites that occurs in red blood cells. This stage begins after the merozoite enters the red blood cell and begins to grow and develop.

The trophozoite has a ring-shaped body and one nucleus. The trophozoite nucleus continually divides, resulting in body growth. Eventually, the body of the trophozoite begins to stretch, which can lead to rupture of the red blood cell.

When the trophozoite reaches a certain stage of development, it begins to divide, forming a schizont. The schizont contains a large number of merozoids, which then leave the red blood cell and begin to infect new blood cells.

It is important to note that trophozoites are a very important stage in the development of malaria, as they can cause serious disease in humans. Therefore, it is important to take measures to prevent infection by trophozoites and other stages of malaria.

Trophozoites are the first anoxic stage of the human life cycle, the malarial plasmodium. Malaria trophozoids cause the disease malaria. Scratching mosquito bites can cause secondary infection of the wound. Most scientists distinguish 4 stages of disease development:

1. The first stage of parasite development is called prozoite. Prozoite is a malaria larva. The duration of its existence is 7-15 days. Mainly found in the stomach of Anopheles mosquitoes. But it is also capable of remaining in the liver and blood of warm-blooded animals for a long time - birds, mammals, reptiles, amphibians. It is from such mammals that the infection is transmitted to humans. Infection occurs when eating food that has already been prepared by an infected mammal. The second site of prozoite reproduction is called the peripheral veins, and is therefore characterized as a hemoglobin-dependent parasite. Prozoite penetrates into the human body through the skin, where it is absorbed through the proboscis of an infected skin.
