Advances In Parasitology
It is a branch of biological sciences that deals with the study of parasites and parasitism
Parasites are organisms that exist on or in another organism and survive by feeding off the host it means that a parasite is an organism which is metabolically dependent on another organism for it survival. The branch of Microbial parasitology deals not only with symbiosis, but also with numerous other such associations with the organisms that sustain both outside and inside of our body, also called as host, hence the name host-pathogen interaction. These interactions commonly take place between a parasite and a host, where the parasites take dual nourishment with the host playing a major role by supporting the parasite, which are either helminths, protozoan and arthropods, which although are parasites, but do not harm the host body, rather, some of them assist the host body in regulating its biological systems. Although, they do not cause any major damage, but they are opportunistic parasites, which cause major damage to the host system primarily when the body’s defence system is weak.
