Host-parasite interactions are very complex processes and play an important role in the ecology and evolution of both the host and the parasite. Such interactions really would be a constant fight between parasites, who use the host for resource extraction, at times harming the host, and the host evolving mechanisms to resist or tolerate the infection.

The category of protozoa and helminths, comprising a huge number of parasites, except the ectoparasites such as lice and ticks, exploit other strategies to invade and survive inside their hosts. In some cases, parasites can modify host immune responses in order to avoid host detection, and in others, actually, they alter host behavior to increase their transmission rate to new hosts.

The host’s immune system recognizes and destroys parasites, and this is the main defense mechanism of the host against parasitic infections. Innate immunity takes the form of an immediate, non-specific response in the form of inflammation and phagocytosis, whereas adaptation is a more specific response involving antibodies as well as memory cells in the long-term immunity.

Besides their critical importance for the understanding of disease dynamics, host-parasite interactions have much more importance in biodiversity and ecosystem health. Work in the area has been contributory in advancing control of parasitic diseases, which are major public health problems in much of the world. A study like this also shed light on species co-evolution and consequences of environmental change in parasite transmission.
