Propionibacterium acnes is a normal member of the skin microbiome that benefits the body by lowering the skin's pH- an antimicrobial effect. However, P. acnes is also the leading cause of acne. Explain mechanistically how can a bacterium be normal and beneficial but also be pathogenic?
List three environments where you would find Staphylococcus spp. On what basis are pathogenic and nonpathogenic species and strains distinguished?
About becterial enzymes, it is CORRECT to affirm that:
a). Some becterial enzymes can help the microbe fight the immune system, by destroying lgA.b). Coagulases are enzymes that use the host's fibrinogen and form a semi-solid get that isolates amd protects the bacteria.c). Some bacterial enzymes such as hyaluronidase can help the microble move through the host's tissus by destroying the tissue's components.d). Fibrolysin is an enzymes that can help from blood clots.
