POWERPOINTS & LEARNING RESOURCES

A complete powerpoint, for Core and HL material: Defence against infectious disease SL HL

REALLY GOOD HL CONTENT ANIMATIONS FROM TES:  https://www.tes.com/lessons/NhbJibdpmiVWmg/ib-biology-11-1-antibody-production-and-vaccination

PERHAPS THE BEST OF THE IB TEACHERS’ WEB PAGES FOR TOPIC 11.1:  http://bioknowledgy.weebly.com/111-antibody-production-and-vaccination.html


Now the reading – excellent! As so often from Biology in Context. There is a lot of reading here. If you are interested enough, go for it! Otherwise, be selective. Keep referring back to the syllabus

FLOREY & CHAIN’S EXPERIMENTS to show the effectiveness of penicillin against bacteria: an ancient but still very good history lesson! https://www.youtube.com/watch?v=7qeZLLhx5kU

Essentially, Fleming made the discovery of penicillin and its apparent ability to destroy ‘germs’ in its path, in the 1920’s. He went no further, even though a standardised toxicity test on mice was available to him. It was left to an Oxford Univerrsity team, led by Florey and Chain in the early 1940’s, to isolate and develop the drug, and learn how to mass produce it. For their work, Fleming, Florey and Chain all received Nobel Prizes.

RESISTANCE TO MALARIA: 

UK-specific update 31/Jan/2017…… Malaria in 4 patients being treated in England was resistant to the usual drug regime, a combination of artemether-lumefantrine. These are the first recorded examples in the UK of the malaria plasmodium becoming resistant.  http://www.bbc.com/news/health-38796337
