32. Infectious Disease, Viruses, and Bacteria

MIT 7.016 Introductory Biology, Fall 2018
Instructor: Barbara Imperiali

This lecture covers microorganisms and some of the threats they pose to human health, such as infectious diseases. Professor Imperiali also discusses antibiotics and the mechanisms by which bacteria become resistant.

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..

[gratefulamateur]

I am an electrical engineer and know zip about microbiology. This was fascinating. Thank you!

[tasadar]

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. <3

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.

She is fantastic at conveying information in an easy to understand manor

very grateful to find such prof to make bacterial resistance more clear thanks alot my darling

A few hours ago I just finished my final for microbiology and here I am watching a lecture of what I just studied.

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

[brainstormingsharing]

Absolutely well done and definitely keep it up!!! 👍👍👍👍👍

[janetanna]

Thank you professor! <3 I was able to finally understand the diff. between gram +ve and gram -ve, even tho I have a degree in microbiology XD

[rameshworibasukala]

Thank you so much ma, am very good lecture.

[ohobrenda]

very good and educational video, this teacher's awesome!

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.

[henocknoelstephan]

Fascinating lecture. As always it’s a pleasure getting to learn from amazing professors!

Mud is mush like coral like thing made by some broke down tree do to high humidity calcium were used as fungus all sort of protozio eventualy did make other side of mountain

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.

Those students are probably working on covid 19 vaccine right now

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.

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

[nibussss]

More it the increased heat?clim changes?
