In both C. difficile–associated disease and bacterial vaginosis, the disease begins when the normal microbiota of the tissue site is altered. Why is this?
Explain clearly why a bacterial infection typically proceeds more slowly than a viral infection?
How does Mycobacterium tuberculosis
gain access through that preferred portal of entry Explain how the Mycobacterium tuberculosis is able to evade innate human host defenses that prevent this from occurring. discuss specific components of your pathogen. (Examples may include capsules, cell wall components, exoenzymes, antigenic variation and penetration of the host cell cytoskeleton.)

- in order for a bacterial pathogen to colonise a host epithelial cell surface, which set of potential virulence determinants produced by the bacteria are most likely to be involved in adherence? Siderophores and outer membrane proteins Fimbriae and outer membrane proteins Endotoxin and fimbriae Peptidoglycan and fimbriaearrow_forwardHow can gut microflora protect people from infection?arrow_forwardPathogenic infections induce damage to the host by a variety of mechanisms. While many mechanisms are direct effects of the pathogen, some damaging mechanisms result from the immune response to the infection. Examples of damage caused by the host immune response are: a) Exotoxin production, endotoxin b) Cell-mediated inmunity, direct cytopathic effect c) Endotoxin, inmmunune complexes d) Direct cythopathic effect, endotoxin e) Cell-mediated inmunity, inmmunune complexesarrow_forward
