Biology and Ecology of Parasites

Parasites range from tiny, microscopic creatures to macroscopic species with a diverse range of classifications. They have various well-developed characteristics that make them sustainable in different habitats with several types of hosts. Parasites develop several types of relationships with their host and parasitism causes damage to the host. Protozoa have unique features and their own classification. Helminths are much more advanced than protozoa as they are multicellular. Arthropods are the most successful creatures on the planet and among them dipterans are more prevalent. Among arthropods, mosquitoes and ticks are the main external parasites that act as vectors of many pathogens. The physical and climatic features of an area help to propagate these parasitic species. Parasitic infection causes a decline in animals’ productivity and causes diseases in humans and animals. For better control of parasitic infections, we should understand the biology and ecology of parasites.
