Introduction to Human Parasitology ⚫ Concept of Human Parasitology ⚫ The Scope of Human Parasitology ⚫ Terms of Parasitology ⚫ Parasites’Harms to Man ⚫ Human Immunity against Parasites ⚫ Characteristics of parasitic diseases

Human parasitology o Human parasitology is the study of those organisms which parasitise humans. According to the very broad definition of parasitology. parasites should include the viruses, bacteria, fungi, protozoa and metazoa(multi-celled organisms) which infect their host species. However, for historical reasons the first three have been incorporated into the discipline of microbiology

Human parasitology ⚫ Human parasitology is the study of those organisms which parasitise humans. According to the very broad definition of parasitology, parasites should include the viruses, bacteria, fungi, protozoa and metazoa (multi-celled organisms) which infect their host species. However, for historical reasons the first three have been incorporated into the discipline of Microbiology

2. The Scope of Human Parasitology Parasitology claims those protozoa(single celled animals), helminths(worms)and arthropods whose existence depends on the availability of host animals It is also possible to argue about whether certain insects and mites are temporary parasites"or micro-predators'", insects as a group belong to the discipline of entomology, while ticks and mites are the concern of Acarology. The insects that are of most interest in human parasitology are those that are vectors of several parasitic infections
