Factors affecting bacterial pathogenicity


Bacterial pathogenicity is the ability of bacteria to cause disease in a host organism. It depends on various factors that influence the interaction between the bacteria and the host, as well as the outcome of that interaction. Some of these factors are related to the host, such as its susceptibility and resistance to infection, and some are related to the bacteria, such as their virulence factors and ability to grow intracellularly. In addition, some factors are related to both the host and the bacteria, such as the presence of host-mediated pathogenesis.
