Microbiology Basics Quiz

study of living and non-living organisms called microbes

it is ubiquitous; virtually everywhere

Two Major Categories of Microbes

infectious particles. eg. viruses and prions

living cell

bacteria and archaea

protozoa, algae, fungi

disease causing

do not cause diseases

potential to cause disease when the host immune system is weak

lives in different parts of the human body and protects

makes the decomposition happen

will turn the dead organism into nitrates, phosphates, and other chemicals that are necessary for plant growth back to the soil

organism that lives on dead or decaying organic matter

process of breaking down substances into simpler forms

this is the process of naturally breaking down substances into harmful ones.

study of the relationship between microbes and the environment

serve as food for tiny animals then they will be eaten by larger animals and so on

microbes in ocean

tiny marine plants and algae

tiny marine animals

use of living organisms to make useful products or process.

substance produced by a microbe that is effective in killing or inhibiting the growth of other microbes

engineered bacteria and yeast to produce a variety if growth hormones, interferons, and materials for use as vaccines.

microbes cause two categories of diseases

pathogen colonizes (inhabits) the body and subsequently causes disease

cause by ingested toxin (poisonous substance) that has been produce by a pathogen in vitro (outside the body)

First microbes in the Earth:

First microbes to be observed by human:

father of microbiology

single lens microscopes

first to see bacteria and protozoa

a theory that life can develop spontaneously from nonliving materials (decaying corpses, soil, and samp gases)

produces different fermentation products

converts the glucose in grapes to ethyl alcohol (ethanol)

convert glucose to acetic acid (vinegar)

what theory did louis pasteur disagree with?

organisms that require oxygen

organisms that do not require oxygen

louis pasteur introduced these words

what process did louis pasteur develop?

kills microbes that were causing wine to spoil; kill pathogen in different types of liquid

what are the 2 germ theory of disease

specific microbes cause specific infectious diseases

Developed vaccines against chicken cholera, anthrax, swine erysipelas and rabies.

He discovered: Bacillus anthracis, Mycobacterium tuberculosis, and Vibrio cholerae

Developed bacterial fixation, staining and photographing methods

Developed bacterial cultivation methods

Prove that a specific microbe is the cause of a specific infectious disease
