To review:
The influence of the hemolysins, leukocidins, coagulase, kinases, and hyaluronidase, siderophores, and IgA proteases to the pathogenicity of microbes.
Introduction:
Microorganisms that have the ability to cause infectious diseases are called as pathogens. This ability is denoted as the pathogenicity of a microbe. Such microorganisms include bacteria,

- Describe several specific adhesins by which bacterial pathogens attach to host cellsarrow_forwardDiscuss how a pathogen causes an infection. Include definitions for primary pathogen, opportunistic pathogen, infection, disease (caused by a living organism), and various stages of pathogenesis. You can choose a specific organism to describe (like Orthomyxovirus and Influenza) or discuss a generalized infection.arrow_forwarddifferentiate desease from infection. differentiate virulence from pathogenicity.arrow_forward
- What structures or substances that can increase microbial virulence or pathogenicity and explain the mechanism of that structure or substance?arrow_forwardWhat is epidemiology? there are several ways pathogens can be transmitted including direct contact, indirect contact, via respiratory droplets, vehicle, and through a vector.
