There are over 150 known strains of bacteria that are considered normal human flora. A. What are some factors enable these “normal biota” to become pathogenic and invade the host? [I am looking for microbe Virulence factors] B. Explain why some bacteria infect specific tissues or regions of the host. (This was in the movie, Bacteria and Humans) C. What are some properties of the bacteria that allow these organisms to evade host defense mechanisms?
help- Additional Questions: 1. Gather information from each of the six tested bacterial strains and write a short summary about each. Include information such as where they are normally found and if they are pathogenic or symbiotic on plants or animals. Where is it normally found? Is it or any relative of it (in the same genus) a human pathogen? If so, what kinds of diseases/ symptoms would you find if infected with it or its relative? Bacillus subtilis I...
