Invasive Stage

The invasive stage of parasite development is the stage that is capable of continuing the life cycle in a new host. This stage may vary for different parasites. For example, cysts of dysenteric amoebas, sporozoites of malarial plasmodia and eggs of pork tapeworm are invasive stages.

Infective stages are important for the life cycle of parasites. They allow the parasite to spread to new hosts and continue its life cycle. This is especially important for parasites that cause disease in humans and animals, as they can spread to new populations and cause epidemics.

To avoid the spread of infective stages, it is necessary to take measures to prevent and control diseases caused by parasites. This may include monitoring the quality of water, food and the environment, as well as implementing preventive measures such as vaccination and animal treatment.

In addition, it is necessary to understand that invasive stages can have varying degrees of danger to human and animal health. Some of them can cause serious illness and even death. Therefore, it is important to be aware of the possible risks and take precautions to protect yourself and your loved ones from infection.



The invasive stage is the development of a parasite that is able to continue its life history in an organ of another organism. For example, cysts of dysentery amoebas, sporocysts of malaria, eggs of pig tsob. The life cycle is the development path of parasites from the moment they pass through
