Introduction to Diseases (02:24)


Infectious diseases are the result of a foreign organism entering a host and can be transferred between people. Pathogens are microorganisms that can cause disease and can enter the body in several ways; learn the six categories of pathogens.

Bacteria (04:22)

Bacteria, single-celled prokaryotic organisms, are common. Learn the four main types of pathogenic bacteria, common types of bacterial diseases, and common treatments. Most bacteria reproduce through binary fission and most found in and on the body do not cause disease.

Viruses (03:55)

Viruses, the smallest of all microbes, are non-living infectious microorganisms comprised of genetic material that cause several diseases. Learn how viruses behave, reproduce, and transmit, and ways to control viral diseases.

Fungi (03:01)

Fungi have a rigid cell wall and are saprophytes or parasites. Most species are made of hyphae. Learn how fungi reproduce and behave, common fungal infections, and ways to treat pathogenic fungi.

Protozoa (03:01)

The single-celled eukaryotic organisms get food from their surrounding environment. Learn how protozoa behave, infect humans, and ways to treat malaria.

Prions (02:48)

The infectious self-reproducing proteins were discovered in the 1960s; they have no nucleic acids. Creutzfeldt-Jakob Disease is fatal and affects one in 1 million people worldwide. Learn symptoms of CJD and see a comparison of normal and abnormal PrP.

Macroparasites (02:51)

These parasites are visible to the naked eye; see examples. Parasitic infections occur worldwide. A range of medications treats infections.

There are a multitude of pathogens capable of infecting the human body and causing disease. This program explores the six main categories of pathogens: bacteria, viruses, fungi, protozoa, prions and macroparasites. Their structure, mode of transmission, and the changes they cause in the host are described. Real-life images, microscopic views of cells and pathogens, and animations make this an excellent resource for the study of pathogens and infectious disease.
