Mysteries of the Microscopic World

Rated 5 out of 5 by from A fascinating overview Great material to give the viewer an overview of microbes, their impact on humans, and the gradual progress of science in discovering and countering them. One missing piece though was the discovery of viruses (the discovery of bacteria was covered). Perhaps the Great Courses could look at a more in depth microbiology course as a follow up ?

Rated 5 out of 5 by from Fascinating You grow up hearing stories about this stuff, but the presentation here is riveting, the information conveyed stunning. He presents a quiet and ironic sense of humor to keep it lively, no droning lectures for this man. I would highly recommend this course for anyone that would like a better understanding of the microbial world we are immersed in.

Rated 5 out of 5 by from Very Relevant Topic Given what is going on in the world right now, a course on microbes is highly relevant. I found the section on the 1918 Influenza to be especially useful. Prof. Fleury devotes three lectures to that topic. If you want to be an informed citizen and expand your scientific knowledge then I recommend this course. Sometimes the material can be a little on the dry side, but the professor always makes sure that the viewer understands the subject at hand. The end result is worth it.

Rated 5 out of 5 by from Important info for today Another winning lecture from Dr.Fleury. So much information,explained nicely for the layperson.Fascinating information concerning the Black Death. I like his lectures because regardless,he imparts his sense of humor along into technical stuff,to help us come to conclusions about what he is teaching us. Sometimes,he injects a "test" question which helps the listener determine if the subject matter is sinking in.btw: WASH your HANDS,is STILLa very good thing to do.

Rated 5 out of 5 by from Incredibly Comprehensive I am 2/3 through the course and continue to be impressed. I have a degree in zoology so am able to assimilate the material but my degree is over sixty years old and is woefully out of date in the area of cellular biology and microbiology. This course not only details the mechanisms of disease and immunology but also the social and historical impacts of disease and disease management. The professor has an encyclopedic knowledge from which to deliver an interesting and sometimes alarming message regarding the ongoing interaction between humans and the microbiological environment as well as the battle among microorganisms for survival and dominance.

Rated 5 out of 5 by from Great details. In explaining. When I was a kid, parents presented me with a microscope and a new world opened to me. This course have greater detail of the microscopic world.

Probe the different mechanisms that humans have evolved to defeat microbial invaders, and the strategies evolved by microbes to thwart those defenses. For example, our immune system is primed to produce fever and other infection-fighting responses, but many microbes have developed frighteningly potent countermeasures....

30 min
Virulence
7: Virulence

Virulence is a measure of the effectiveness of a microorganism at killing its victims. Discover that many diseases, such as syphilis, scarlet fever, and diphtheria, have grown less virulent due to competition and coevolution. On the other hand, vector-borne pathogens often succeed by growing more virulent....
