Study Notes
Microbial Pathogenesis
- The first important step in establishing microbial pathogenesis is adherence, which is the ability of a microbe to stick to a surface or to other microbes.
Adherence and Biofilms
- Microbes need to establish adherence to each other to form biofilms, which are complex communities of microorganisms that adhere to each other and to surfaces.
Pathogen Entry
- A pathogen can gain entry past the epithelia of the host through various means, such as penetrating the epithelial barrier, exploiting junctions between epithelial cells, or using host cell membrane invaginations.
Adherence to Cellular Substrates
- Specific adhesins and receptors are important for adherence to cellular substrates, allowing the microbe to bind to the host cell surface.
Importance of Entry Site
- The specific entry site is important for microbial pathogenesis because it determines the type of host cell and tissue that will be infected, and the subsequent outcome of the infection.
