    Wow! I could sit and listen to your professor all day long! She’s extremely smart and very articulate. I’ve graduated from 2 different colleges and I never had a professor this good..

    As a recent biochemist graduate, thank you oh so much for these lectures! I understand about 80% something I could not phantom 3 years ago.

    10:00 it's important to mention that all of these resistances take a toll on the replication rate and viability of the pathogens.
    Whereas normal E. coli would take 12 mins doubling time at perfect conditions, penicillin resistance will make it 2 hours doubling time.

      I've heard of doubling times as little as 20 minutes but never 12

    I love how even folks at MIT question whether or not they are pronouncing the names of bacteria correctly. Glad I'm not alone :D

    Minor technicality, at the beginning of the lecture about most dangerous animals: I thought that bacteria and viruses are not cassed as animals (i,e. they are members of different biological kingdoms). Still it.as aninteresting lecture.

    Humans have gone to moon, learned the bacterial cell wall molecule structure through organic chemistry, and sequenced their own DNA - but they can't use readable font size in slides.

    Mycobacteria....cell wall strongest?
    Hard to kill?

      This is a introductory level course. You don't get to work on vaccines and such until you graduate and even then you wouldn't be leading any studies. You usually need a Ph'D and that takes at least 6 more years after the initial 3 or 4 years to get your B. Sci

    I'm interested in disease from industrial toxins, in particular, toxins in industrial/technological medicines (virtually all based on petrochemicals). So we have on our hands probably the greatest irony in human history, that is, that the main causes of disease cannot be named because government and industry have always been in bed with eachother. Government protects industry, the economy, and capitalism. At 8:30 the speaker says once we thought we'd take care of microbes with our drugs. Not so. The 'we' refers to the Western biomedical model which always had its critics. In the early 1940s, it was correctly argued that the birth of a new system of national healthcare, as envisaged by the creators of the NHS in the UK, would lead inexorably to an expansion in illness. That's how capitalism works, and that's exactly what we've seen year on year. No purported virus has ever been isolated and the idea of viral pathogens is make-believe.

      Yes. We understand what a virus is .
