chapter 10 part 1
| Question | Answer |
|---|---|
| in hospitals, infection control is | crucial |
| immune systems are compromised by | severe disease |
| in hospitals, microorganisms can be | resistant to antibiotics |
| the cause of the infections/diseases until recently weren't | fully understood |
| slowly cntury by century, knowledge of infections | progressed |
| the 1st crude microscopefor observing microorganisms was made by | Dutch merchant Anton Van Leewenhoek in 1673 |
| Robert Hooke was an Englishman who was the 1st to | use microscopes to observe plant cell structure |
| in 1798, Edward Jenner discovered the | principle of disease immunization |
| germ life was just believed to come from | moist soil or decaying flesh before 1850 |
| in 1861, french scientist, Louis Pasteur demonstrated that microorganisms that are present in air | doesn't generate microbial life |
| Louis Pasteur found that microorganisms | infect mammals |
| louis pasteur developed a heating process that | molds milk & kills bacteria (pasteurization) |
| pasteurization was meant to keep people from | bacterial microorganisms exposure |
| louis pasteur's work was followed up by | English surgeon joseph lister |
| joseph lister knew that carbolic acid kills bacteria & he | disinfected surgical dressings with it |
| he developed antiseptic | surgery methods |
| he saved thousands of lives with his sterile surger techniques which reduced | post-surgical infections |
| viruses are genetic material | in protein microorganisms |
| viruses can't reproduce without a | host |
| viruses cause | colds, flus, mumps, etc. |
| a mynute infection that doesn't have complete cell components need | cell of a living host to replicate |
| fungus is a parasite that slowly reproduces with | spores |
| molds, mildews, & mushrooms are | fungi |
| fungi are sigle celled organisms that have | no chlorophyll, no cell wall, & feeds on living organisms and dead organic material |
| penicillin is found in | fungus |
| the infections that fungus causes are | athlete's foot, ring worm, yeast, & other more serious infections |
| protozoa has one cell or | many identical cells |
| protozoa live in | water, soil, & in other creatures like parasites do |
| paramecia & amoeba are | protozoa |
| protozoa can cause | sleeping sickness, malaria, & dysentary |
| epidemics & pandemics killed millions before | microorganism scientific control |
| 137 mill. europeans died from | bubonic plague |
| in 1876, robert koch defined (koch's postulates) steps that could | certain organisms cause certain illnesses |
| robert koch conducted research on | anthrax infected cattle |
| bacterial microorgansms are | single celled |
| the 3 main bacterial forms are | cocci, bacilli, & spirochetes |
| cocci are | spherical |
| bacilli are | rod shaped |
| spirochetes are | spirals |
| bacteria causes infections like | food poisoning, strep throat, ear infections, rheumatic fever, meningitis, pneumonia, tuberculosis, pink eye, and acne |
