How can microbes be controlled: immunization: after getting infected by pathogen your body forms defenses against that pathogen. So you will have a shorter recovery time the next time you get infected by that same pathogen: vaccination: inoculate (infect) individual with a less virulent form of the pathogen to get immunity. For the smallpox vaccination edward jenner vaccinated people with cowpox: antiseptics/disinfectants. Ignaz semmelweis noted a decrease in fever due to hygienic practices. Antiseptic= antimicrobial substance used to reduce possibility of infection: antibiotics: treat and prevent bacterial infections. Alexander fleming: discovered penicillin: penicillin prevents bacteria from making their cell wall. Microbes play a important role in natural ecosystems: winogradsky and beijerinck importance of bacteria in geochemical cycling. Metagenomics- analyze genome of environmental sample to get info on. Due to bacteria and fungi organisms in their natural state: about their physiology and genetics. Protein, rna, water, inorganic ions, organic molecules, dna, ribosomes, inclusion.
