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 macro-parasites. 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...

Before the advent of antibiotics in the 1930s it was not uncommon for people to die of pneumonia or appendicitis, and medical procedures we now take for granted were impossible to perform due to the risk of deadly infection. It's hard to imagine returning to that era, but many believe that if the problem of drug-resistant bacteria is not sufficiently addressed, it's a future we'll have to face. This program examines the rise of superbugs, introducing...

Although the Spanish flu caused far more fatalities than World War I, the film shows how large-scale trench warfare amplified the spread of the virus. Frantic methods used by urban centers to fight the advance of the disease are...

Why did Dutch virologist Ron Fouchier and his team of researchers purposely engineer a lethal, airborne bird flu virus? That's the first of many questions raised in this timely, eye-opening investigation. Why did Fouchier, in an uncanny parallel with American scientists who conducted similar experiments, decide to publish his findings and openly share his working methods? Can the deadly microbes he produced be contained securely, or are they vulnerable...
