Dispersal

Definition

Dispersal is the process by which microorganisms spread from one location to another. This can occur through various mechanisms such as air, water, or host organisms.

5 Must Know Facts For Your Next Test

1. Dispersal enables microbes to colonize new environments and access new resources.
2. Mechanisms of dispersal include passive transport via wind or water and active movement by the microbe itself.
3. Dispersal plays a crucial role in microbial survival and evolution by promoting genetic diversity.
4. Biofilms can enhance microbial dispersal by providing protection and aiding in attachment to surfaces during transit.
5. In human health, dispersal of pathogenic microbes can lead to the spread of infections.
