Document Summary

For each of the s. pneumoniae cell components listed below, briefly indicate how it could contribute to the ability of this bacterium to cause disease in a human host (~1 sentence for each) Capsule: resistance to phagocytosis, prevents anti-bodies from binding, Attachment (pila) pilus: allows attachment to host which instigates colonization. Pspa: inhibits complement activation and impairment of complement receptor-mediated protection. Virulence factors- molecules produced by pathogens colonization of a niche in the host immunoevasion, evasion of the host"s immune response immunosuppression, inhibition of the host"s immune response. Entry into and exit out of cells. Obtain nutrition from the host: below are 3 (cid:373)edia recipes. Medium 1 is complex because there are components such as extracts that are not clearly defined. They are not chemically defined: s. pneumoniae can grow in medium 1 and medium 3, but not in medium 2. It cannot utilize sodium citrate as its main carbon sourse.
