Mention and explain two virulence factors of bacterial pathogens
Step by step
Solved in 2 steps
- Differentiate between a microbe’s pathogenicity and its virulence.Explain the role of ' resident flora' in preventing infection and as source of infectionDiscuss the following virulence factors: collagenase, hemolysin, siderophore. For each, explain the molecules involved, the pathogen-host interaction, and name a species and disease associated with each factor.
- differentiate desease from infection. differentiate virulence from pathogenicity.Define virulence factors and identify those of bacteria, viruses, and eukaryotic pathogens.Use the following formula to explain the relationships among theseveral factors and what happens when they change:Infection (infectious disease) = No. of organisms × Virulence _____________________________________ Host resistance
