L-1 An intro to microbiology

the study of microorganisms -bacteria -fungi -single cell eukaryotes

viruses prions

can be commensal, pathogenic, environmental -bacteria -fungus -virus -parasite

• collection of bacteria, viruses, and fungi that live in and on human body • 10 times bacterial cells then human cells in the body • gastrointestinal tract

pass 25 tonnes of faeces in your lifetime plays a role in - nutrition - development - immunity - behaviour - protection against harmful bacteria

digestion - found in digestive tract for digestion and vitamin synthesis medicine - antibiotics and drugs can naturally synthesise by microbes

primary - cause death upon infection not associated with host opportunistic - cause disease under certain circumstances

ozone layer

eukaryotes - fungi - algae - protozoa prokaryotes - Archaea - bacteria

viruses

microbial differ in size, shape, metabolism, environmental adaptability

bacteria

non-pathogenic

spontaneous generation production of life from vital forces in non-living matter

organisms arose from seeds or germs that had entered the food from air

Used disinfectant to treat surgical wounds, greatly reducing infection rates. Considered the father of antiseptic surgery

First person to conclusively prove that a specific bacterium caused a disease

Treatment of a disease by using a chemical substance. Chemical must be more poisonous to microbe than host

first known chemical to treat a disease (malaria)

made in laborator

produced naturally by fungi and bacteria

discovered penicillium
