_____________ is the study of living organisms (viruses, bacteria, etc.) that are too small to see
with the naked eye - ANS Microbiology
There are some exceptions, microbiology also includes the study of __________ such as worms
which are visible to the naked eye - ANS pathogens
Microbiology encompasses _____________, _____________, _____________, _____________,
_____________, _____________ _____________, and _____________ - ANS agriculture,
biotechnology, bioremediation, symbiosis, chemotherapies, opportunistic pathogenesis, and
pathogenesis
An example of micobio in agriculture is the _____________ _____________ bacteria which
form and live in _____________ _____________ nodules. These bacteria turn into an ammonia
like compound, nitrogen is then in the ground from the alfalfa with the nodules. -
ANS nitrogen-fixing, legume root

,An example of biotechnology is that genetic changes that happen in plants are very similar to
the _____________ _____________ changes that happen in an _____________ when they
have cancer, etc. - ANS gene expression, animal
_____________ is solving a problem by using an organism. Fertilization is the problem being
solved in the agriculture example. - ANS Bioremediation
An example of symbiosis is the _____________ _____________ which attach to the Hawaiian
bobtail squid. The _____________ _____________ are on the skin of the squid, which allows it
to their hide shadows and camouflage themselves - ANS vibrio fischeri
_____________ are chemical treatments, and 85% of antibiotics are from microorganisms.
Penicillin was discovered when an experiment didn't work - ANS Chemotherapies

system. Pseudomonas aeruginosa is an example of this. - ANS Opportunistic pathogenesis
_____________ _____________ and people with _____________ _____________ are
extremely susceptible to opportunistic pathogenesis. The skin is extremely important in keeping
these out. - ANS Burn victims, cystic fibrosis.
_____________ is the creation of disease in a healthy individual - ANS Pathogenesis

_____________ _____________. He never told anyone how he made it. He was the first to
discover microbes - ANS Antonie van Leeuwenhoek; wee animalcules
Simple microscopes have _____________ lens - ANS one
_____________ _____________ used a compound microscope to discover that large organisms
were composed of microscopic cells, all macroscopic things are made of microscopic
components - ANS Robert Hook
_____________ _____________ invented the first vaccine against rabies. At this point, only 3
humans had survived rabies. - ANS Louis Pasteur
Louis Pasteur also invented _____________ and disproved _____________, spontaneous
generation (living things arise from non living matter) - ANS pasteurization, abiogenesis
