ch 1 Flashcards
microorganisms
organisms to small to be seen with the naked eye
germ
rapidly growing cell
ways microbes affect our lives
decompose waste, photosynthesize, industrial chemicals, ferment foods, manufactoring products
why are latin binomials important
tells how things are related and used world wide
how do you write a latin name
genus capitalizes and specific epithet lowercase, italicized or underlined
major characteristics- bacteria
prokaryotes, peptidoglycan cell walls, binary fission
major char- archea
prokaryotic, lack peptidoglycan, live in extreme environments, thermophiles
major char- fungi
eukaryotes, chitin cell walls, use organic chem for energ, yeasts are unicellular, composed of fillaments called hyphae
major char- algae
eukaryotes, cellolose cell walls, photosynthesis
major char- viruses
acellular, DNA and RNA core w a protein coat, can only replicate in a host cell
major char- multicellular animal parasites
eukaryotes, flatworms and roundworms (helmiths)
toxonomy- did king philip come only for good sex
domain, kingdom, phylum, class, order, family, genus, species
3 domains
bacteria, archaea,eukarya
4 eukaryotic kingdoms
protists, fungi, plants, animals
Hooke
reported that living things were composed of little boxes-cells
VanLeeuwenhoek
father of microbiology, developed first microscope
Virchow
cells arise from preexisting cells
Pasteur
microbes responsible for fermentation, spoilage bacteria-using heat to kill microbes
Lister
used chemical disinfectant to prevent surgical wound infections
Koch
proved bacteria caused anthrax and provided experimental steps
Jenner
innoculated against smallpox
Ehrlich
“magic bullet” that could destroy a pathogen w/o harming the host
Semmelweis
handwashing
Fleming
antibiotic penicillin
Identify the importance of Koch’s postulates
proves a specific microbe causes a specific disease
- microorganisms must be found in all affected org but not health org
- isolate and grow in pure culture
- cause dx when given to healthy
- be reisolated from inoculated host
spontaneous generation
living org arise from non-living matter-“vital force”
biogenesis
living organisms arise from preexiting life
microbiota good or bad
good-recycle nutrients, bad-pathogens
4 beneficial act of micro
detoxify pollutants, insecticides, biofilms, biotechnology foods
emerging infectious disease
new diseases and diseases increasing in incidence- MRSA, west nile, CJD, HIV
