Document Summary
Week 9 lecture 2: the value of a one health approach for mitigating infectious. Most infectious diseases are caused by microorganisms: microorganisms are organisms that are too small to be seen by the naked eye. Can grow or survive as single-celled individuals or particles: cells = prokaryotic or eukaryotic, can replicate themselves, biological particles = viruses, prions, rna, have to use the cells to make copies of cells, ex. common flu. Eukaryotes: larger and more complex than prokaryotes (ex. algae, fungi, etc: = human body. Prokaryotes: smaller and less complex (ex. bacteria) But not all tiny living things are micoorganisms: microorganism does not include obligate multi- cellular organisms with detailed body plan or tissue. Acellular = biological particles: prions, ex. mad cow disease: proteins that can cause diseases. Cellular must be able to grow as single cells: whereas biological particles need cells to replicate (use your cells to make copies of themselves)
