Diverse Prokaryotic stationary/motile heterotrophic(feed off organic food) /autotrophic(make own food) ubiquitous - everywhere in the world Cell wall- peptidoglycan

Diverse Prokaryotic- small,no organelles, etc Extremeophiles odd/non existent walls

Unicellular Eukaryotic No cell walls- if pathogens get close it makes it harder to treat stationary/motile Heterotrophic can be pathogenic

multi/unicellular Eukaryotic Good recycler Heterotrophic cellwall= chitin Some pathogenic

multi/unicellular Eukaryotic Cell wall= cellulose Autotrophic

Multicellular Animals kingdom No cell wall Some pathogenic

five kingdoms of life

animalia plants fungi bacteria- elbacteria, eukorytes protists- archae

What makes algae different from the rest of the eukaryotes?

Its autotrophic which means it is not pathogenic because it makes its own food

Tissue specific/specie specific Not real due to being acellular which means no cells All obligate intracellular parasites All pathogens Dna or Rna never both

Genes from one species contain genes from other species giving organisms new abilities. (pig insulin->human insulin)

Study of family trees in microorganisms related thru evolution

Study of an important part of ribosomes protein making machine and study its evolution of microbes.

Recombinant dna technology (GMOS) is?

recombining/rearranging dna by from different sources in order to modify genes, make medicines, and study genes.

Spontaneous Generation vs. Biogenesis

Spontaneous Generation: The old belief that living things could come from non-living things (e.g., flies from meat). - VITAL FORCE Biogenesis: The idea that life comes only from other living things.- Louis Pasteur

Germ theory of disease

Specific germs cause specific diseases proved by Pasteur and Koch Led to better hygiene, sterilization, and disease prevention.

Study of the cause of diseases, helped identify microbes to differrent diseases. Introduced by robert koch.

A set of steps to prove a microbe causes a specific disease: Find the microbe in all sick organisms. Isolate and grow it in pure culture. Inject it into a healthy organism and see if it causes the same disease. Re-isolate the same microbe from the newly sick organism. This helped establish cause-and-effect in microbial diseases.

Methods to prevent contamination by unwanted microbes. Introduced by Joseph Lister, inspired by Pasteur. Includes hand washing, sterilizing tools, and using clean environments in surgery and labs.

Introducing pathogens to the immune system for quicker response.

antimicrobial chemotherapy and antibiotics

Antibiotics come from natural sources (fungi and bacteria) to defend from others and are used in people. It is a magic bullet kill disease and barley damage host Fleming discovered penicillin from mold and mold increases penicillin to kill of competition

The study of the immune system — how the body defends itself against microbes

The study of how diseases spread in populations — who gets sick, when, where, and why.

Emerging Infectious Diseases- EID

New or increasing diseases that are becoming more common, dangerous, or spreading to new areas.

Pasteur’s Swan-Neck Flask Experiment

Pasteur boiled broth in swan-necked flask to kill any microbes. The flask had a curved neck that allowed air in, but trapped dust and microbes in the bend. Because no microbes could reach the broth, nothing grew — the broth stayed clear. But when he broke the neck (so microbes could get in), microbes grew in the broth! Microbes come from other microbes in air not from broth
