General Parasitology is the study of parasites, their biology, life cycles, and interactions with host organisms. Parasites include protozoa, helminths, and arthropods that live on or inside a host, often causing harm. This field explores how parasites infect, survive, and reproduce within their hosts. Parasitology also examines host immune responses and mechanisms of parasite evasion. Transmission often occurs through contaminated food, water, vectors, or direct contact. Common parasitic diseases include malaria, schistosomiasis, and ascariasis. Diagnosis, treatment, and control of parasitic infections are key components of this field. General Parasitology is vital in medicine, veterinary science, and public healt
