Why do we study pa arasites? Inability to raise livestock in Africa has led to poverty 2. Debilitating effects of parasitic diseases on humans results in a loss of labour 3. Bringing huge economic losses Thus, an understanding of parasites is important to students in biology the medical sciences, the veterinary sciences, and public health

1.What is Parasitology?
Definition of Parasitology It studies the pathogenic parasites and their relationships to the hosts and environment Parasites traditionally have included the study of three major groups of animals: parasitic protozoa, parasitic helminthes(worms), and those arthropods that directly cause disease or act as vectors of various pathogens. It encompasses aspects of biology, pathogenesis, diagnosis, epidemiology, treatment, prevention and control Parasitology is usually in the scope ofpreventive medicine and the foundation of clinical parasitic diseases
