Allegation:

The shared bacterial, archaeal and viral genera detected in this study suggest that respiratory tract disease associated microbiomes could have a profound impact on the pathogenesis of SARS-CoV-2 infection and severity of the disease. Moreover, the predominantly abundant bacterial pathogens along with the archaea and bacterial viruses (phages) could have important contribution for the generation of immune responses against viral attack, and this secondary microbial community might affect the outcome of COVID-19.

Test:

Among the non-cultivation-based approaches, several may prove useful for the identification of potential archaeal pathogens, including nucleic acid-based methods, gas chromatography, mass spectroscopy, and microscopy. Over the past decade, PCR amplification, cloning, and sequencing of phylogenetically informative molecules, such as small subunit ribosomal DNA, have become standard tools for identifying both known and unknown microorganisms in complex microbial communities (10, 43, 51). The large number of unique genes evident within archaeal genomes should provide additional opportunities for the selection of specific archaeal targets (3, 52). Although the use of DNA microarrays for high-throughput microbial classification and identification is still in its early developmental phases, this approach offers the advantage of massively parallel screening of nucleic acid molecules from complex populations. Quantification will be crucial in situations where the disease process is dependent on the relative abundance of the pathogen.

When Archaea was first identified as a separate domain of life, its members were viewed as extremophiles and thus foreign to the human habitat and microbial ecosystem. This moniker was not a true reflection of archaeal physiology but rather a result of limited data and a narrow scientific perspective. Molecular approaches have now revealed archaea in decidedly nonextreme environments. It is not unreasonable that the application of similar techniques to the human “environment” may expand our perspective yet again.

Conclusion (no big citation, just me):

Most aquarist don't know 'nitrogen fixing bacteria' are archaea and not bacteria.

While archaea have been known to science since 1977, Könneke was the first to observe ammonia oxidation in archaea. Scientists now have a special name for these organisms: ammonia-oxidizing archaea, or AOA. Following Könneke's 2005 discovery, other groups of scientists came to realize the abundance and importance of AOA.

That means the most important molecules needed for this planet to harbor life are archaea, and we also might be (at least important parts) archaea.

Whatever the future means be it informing people of the reproductive dangers or finding a cure, we all know the evidence of what was done is going to evaporate. We will never know, as Q said.

How we will figure out who is damaged and who is not is probably through this avenue. It will also likely be a vast new field for medicine and science.

Mitochondria evolved from an endosymbiotic alphaproteobacterium within an archaeal-derived host cell that was most closely related to Asgard archaea.

My fear is that if the most important parts (mitochondria are archaea) of us are damaged at the genetic level that we won't be able to do much and will have to initiate quarantine / segregation protocols.

Some countries might be harsh with them, I would vote for informed choice prevailing not over personal privacy. A test may be made that you can take but no law should force you to disclose. I'll get backlash for this. I feel the same about AIDS. I also feel if you engage you risk all kinds of things even outside disease like divorce and kids. It's my opinion and I won't defend it, I'm open to disagreement.

How we would identify persons (whatever the result of being found) would probably be through these means.

My greatest fear is nothing is done and there's a lot of pee in the gene pool. To test for pee in a pool you test for artificial sweetners.

To test for gene alteration test the archaea.

TLDR; Modern medicine is changing the oil on an electric vehicle.
