Detailed explanation-1: -No definitive virulence genes or factors have been described in archaea to date. Nevertheless, archaea may have the means, and they certainly have the opportunity, to cause disease. Archaea share some characteristics with known pathogens that may reflect the potential to cause disease.
Detailed explanation-2: -What diseases are associated with Archaea and their viruses? Surprisingly, no Archaea is known to cause human disease and therefore no archaeal viruses are known to be involved with modulating pathogenesis in humans.
Detailed explanation-3: -Martin 16 postulates that Archaea are not pathogens because they use different co-factors in their biochemical reactions compared to Eukarya (and Bacteria). Eukaryotes would, therefore, not provide a good source of nutrients for Archaea.
