ANSWERS TOP GRADED 2024
Germ Theory of Disease - idea that infectious diseases are caused by pathogens
Early ideas about disease transmission - punishment for sins, miasma, hexes/spells,
spontaneous generation
miasma - a highly unpleasant or unhealthy smell or vapor
Louis Pasteur - A French chemist, this man discovered that heat could kill bacteria
that otherwise spoiled liquids including milk, wine, and beer.
-disproved spontaneous generation
-vaccines for rabies and anthrax
Robert Koch - country doctor in east Prussia
-verified germ theory of disease (anthrax)
-showed same microbes caused same disease repeatedly
-TB, cholera, malaria
Golden Age of Microbiology - 1854-1914
-many pathogenic bacteria identified
-early work on viruses
-Germ Theory of Disease established
microbes - -diverse and found everywhere
, -most are not pathogens
bacteria - -small, simple, prokaryotic
-major involvement in environmental processes
-most harmless, some beneficial
-TB, plague, cholera, typhoid fever, typhus, strep throat, staph infections,
whooping cough
-almost all treatable with antibiotics, vaccines for few
viruses - -acellular microbe, smaller than bacteria
-infect all forms of life & NEED host to reproduce
-smallpox, AIDS, influenza, chicken pox, common cold
-vaccines for many
-antiviral drugs NOT exist
how viruses replicate - 1. virus attaches to cell - virus has nucleic acid
2. virus penetrates cell membrane and injects its nucleic acid
3. viral nucleic acid replicates using host cell
4. viral nucleic acids are packaged in viral particles and released
funghi - -multicellular molds & single celled yeast
-involved in environmental processes, many beneficial
-athletes food, yeast infection, some respiratory
-no vaccines, anti-fungal drugs available
parasites - -disease causing protozoa, worms or flukes
-have complex life cycles
-no vaccines, anti parasitic drugs for most
protozoa - -unicellular
-malaria, African sleeping sickness, giardiasis, amoebic dysentery
worms - -multicellular
-hookworm, roundworm, river blindness
flukes - -multicellular
-schistosomiasis
infection - microbe living in a host
