Properties of trematodes of the BILHARZIELLIDAE family

Abstract

Different types of trematodes have different periods of development. Parasites swallowed by the definitive host turn into sexually mature parasites. This cycle is characteristic of trematode worms. In another way of development, the cercariae enters the second intermediate body of the host and turns into the next stage - metacercariae . The second intermediate inhabitants are various types of fish and crustaceans. Metacercariae, together with the second intermediate body of the host, enter the body of the main host and reach sexual maturity. Thus, adolescaria and metacercaria enter the body of the definitive host. Cercariae penetrate the skin and mucous membranes, they do not have larval metamorphosis. Thus, the general name of the diseases called Trematodiasis. The main causative agents of trematodosis and the ways of their penetration into the human body are different. In addition, different types of trematodes have different periods of development.

Trematodes (or flukes) are parasitic worms . They inhabit humans and animals. Trematodes in humans affect blood vessels, lungs, digestive tract and liver. In the absence of timely diagnosis and treatment, the disease leads to severe complications, death . Who are trematodes. Trematodes are flatworms. More than 7200 species of these parasites are known, 40 of them can live in the human body.
