- When antibody marks an invader so the macrophages can find it more easily to efficiently destroy the microbe, this process is called ___. inactivation coagulation opsonization agglutinationThe process where antibody attracts macrophages to invading microbes by making them more appealing or "tasty" is ___ polymerization agglutination inactivation opsonizationYou might expect that lysozyme, the protective mechanism included in mammalian tears would protect against which of the following potential pathogens: Each other answer is correct ("all of the above") Archaea Microbial Eukaryotes Bacteria
- Clot and scab formation occur as part of this process: Group of answer choices cytolysis hematopoiesis phagocytosis inflammationThe process of macrophages bringing microbes inside the cell to destroy them is called: diapedesis chemotaxis leukocytosis phagocytosisHow do you think a bacterial cell would respond if it was treated with the antibiotic vancomycin compared to the antibiotic erythromycin? Note: this question is asking about the bacterial response, not the specific action of the antibiotic, although you need to know this to answer the question.
- Microbes possess many different strategies to help them cause disease called virulence factors. Explain how two virulence factors work. For each virulence factor state the name of the mechanism, explain how it works and what advantage it gives the organism that helps it cause disease.Which of the following is not an example of the physical, mechanical, and chemical barriers at body surfaces that prevent most microbes from entering the internal environment? The flushing action of urination Sticky mucus secreted by the epithelial tissues of the body's interior Phagocytosis by white blood cells The thick waterproof layer of dead cells that make up the skinBack to Mr. Doe and his MRSA which over time is becoming more and more resistant to brincomycin. In the diagram below time is moving from left to right. Drag-drop the arrow-labels and the captions to describe how Mr. Doe's MRSA is evolving resistance to brincomycin. You only need to label one moment of diffusion, one pump and one molecule of brincomycin. Time 1 Time 2 Time 3 brincomycin Efflux Pump Diffusion into cell MRSA MRSA MRSA Efflux pump removes MRSA Efflux pump grabs brincomycin as fast as it diffuses in, cell MRSA antibiotic better, pumps it out faster, less brincomycin stays in cell MRSA Efflux pump grabs antibiotic inefficiently, pumps it out slowly, not damaged by the antibiotic What is happening: brincomycin stays in cell long enough to damage it MIC = 8 MIC MIC = 1 MIC =2 E Notes Comments W 33°F
