Abstract Purpose of Review Since the introduction of Archaea as a new domain of life more
than 45 years ago, progress in their phylogenetic classification and knowledge of their …

In this work, we review the state of knowledge of Archaea associated with the human
microbiome. These prokaryotes, initially discovered in extreme environments, were named …

Highlights•Archaea have been established as abundant and prevalent microbial
components of host microbiomes.•Not a single archaeal pathogen has yet been identified …

A decade ago a hypothesis was proposed that, similar to the Bacteria and Eukarya, the
archaeal domain of life might harbor certain species capable of causing disease (Cavicchioli …

This work represents an update of knowledge regarding the detection methods for human
microbiome-associated archaea. Despite the fact that, during the last three decades, only …

Over 40 years ago, Carl Woese and his colleagues discovered the existence of two distinctly
different groups of prokaryotes—Bacteria and Archaea. In the meantime, extensive research …

It was only approximately 20 years ago that the noun Archaea entered the lexicon of clinical
microbiology, when it became increasingly apparent that these prokaryotic organisms, which …

Host-associated microbial communities have an important role in shaping the health and
fitness of plants and animals. Most studies have focused on the bacterial, fungal or viral …

Recently, thanks to the revolution of molecular biology techniques, there has been a rapid
development of research on human intestinal microbiome. The use of modern molecular …

Prokaryotes forming the domain of Archaea, named after their first discovery in extreme
environments, are acknowledged but still neglected members of the human digestive tract …
