Parasitology is the branch of biology that studies parasites, their hosts, and the interactions between them. It encompasses various aspects, including:
Types of Parasites: Parasitology examines different kinds of parasites, such as protozoa (single-celled organisms), helminths (worms), and ectoparasites (like fleas and ticks).
Host-Parasite Interactions: This field investigates how parasites interact with their hosts, including the effects of parasitism on host health, behavior, and ecology.
Life Cycles: Parasitologists study the life cycles of parasites, including how they reproduce, develop, and spread among hosts.
Disease: Many parasites are responsible for diseases in humans, animals, and plants. Parasitology addresses the diagnosis, treatment, and prevention of these parasitic diseases.
Ecology and Evolution: The field also explores the ecological roles of parasites and their evolutionary adaptations.
Overall, parasitology is essential for understanding the biology of parasites and their impact on health and ecosystems.

Entamoeba histolytica can be described as an anaerobic parasite amoebozoan that is part of the Genus Entamoeba. It is a major cause of infection for humans and other primates , causing amoebiasis. E. histolytica is estimated to affect between 35 and 50 million people across the globe.
What is Host-Parasite Interactions? Types of Hosts In parasitology, hosts play vital roles in the life cycle of parasites. Each type of host has a specific function that contributes to the survival and development of the parasite. Understanding these types helps in comprehending how parasites interact with their hosts and spread diseases. Below are the … Read more

What is Parasitology? History of Parasitology The history of parasitology encompasses a rich tapestry of discoveries and advancements that highlight humanity’s ongoing struggle to understand and combat parasitic organisms. This narrative intertwines with the broader history of medicine, particularly in the context of tropical diseases, where many parasites are prevalent. Below is a structured overview … Read more
What is Cysticercosis? Clinical manifestations of Cysticercosis Cysticercosis is a parasitic infection caused by the larval stage of the tapeworm Taenia solium. The clinical manifestations of cysticercosis depend on the location of the cysticerci (larval stage) within the body. It’s worth noting that not all patients with cysticercosis will experience symptoms. Asymptomatic cysticercosis is often … Read more
