Staphylococcus Species and the Most Pathogenic Species Among Them
The three main species of Staphylococcus are S. aureus, S. epidermidis, and S. saprophiticus. The most pathogenic species among the three is S aureus. It produces enzymes and toxins that negatively affect its hosts' cells (Foster, n.d.). Hemolysis can eliminate the red blood cells while the enzyme coagulase clots the plasma, and leukocidin eliminates the leukocytes. In contrast, S. epidermis and S. saprophitcus are relatively not as pathogenic as S. aureus (Akinkunmi et al., 2014).
Factors Determining Pathogenesis of Organisms
The virulence factors determine the degree of pathogenesis in organisms. Besides causing infections to the hosts, virulence factors play a crucial role in helping the reproduction and growth of microorganisms. They help microorganisms grow in high temperatures, help in penetration and dissemination required by pathogens to enter and establish themselves in their hosts (Meena, 2019). Additionally, the virulence factors enable pathogens to resist the immune system of the host. For instance, S. aureus contains several virulence factors that compromise the effectiveness of the hosts' first line of defense. It produces proteins that interrupt neutrophil chemotaxis and neutralize defensin peptides (Goldmann & Medina, 2018). Also, ...
