Review: Parasite Strategies to Escape Attack by The Immune System of Their Hosts

Abstract

This review aims to investigate the parasitic strategies that enable them to escape attack by the immune systems of their hosts and cause infection. A parasite is a creature that obtains its sustenance and other requirements from a host, which is another organism that provides support to the parasite. Medical parasitology encompasses protozoa, helminths, and some arthropods. Parasitic diseases lead to host immune responses that expel the infesting parasites. Parasites also have improved a number of strategies to prevent host immune attacks and survive in the environment of the host. In this study, all information about the parasites abilities to avoid host complement immune attack in a hostile environment and the mechanisms of complement immune evasion is provided.
