Immune evasion is initiated by the parasite and the host is the responding party. The necessary machinery is part of the parasite’s genomic endowment even when the parasite usurps the host’s immune defence system for its own benefit (e.g. by using host enzymes (Nomura et al. 2006) or by sequestering gene sequences from the host (Seet et al. 2003)). At the same time host and parasite face asymmetrical consequences should immune evasion fail.
Pathogenic bacteria have evolved multiple mechanisms aimed to evade host defenses. This review summarizes selected examples of how bacteria utilize proteolytic enzymes to efficiently establish and spread infection systemically. First the role of proteases in intracellular survival and persistence – …
It has been suggested that the resistance of this parasite to the host’s hydrolytic enzymes is due to surface components that inhibit the host’s enzymes and/or to the presence of parasitic enzymes that hydrolyze the host’s enzymes. As previously noted at least one protozoan parasite Theilera is capable of growing directly in lymphocytes. Therefore this parasite may escape the host’s immune response by growing inside the very cells required for the response.
When S. aureus first infect the host there is a robust activation of the host innate immune responses. Generally…
