Cool! Has anything similar been attempted in tumor tissue, given the many claims of microbes in tumors? Especially tumors not in contact with the exterior.
As far as I know, most of the tumor microbiome claims haven't held up very well. For example, the 2020 Nature paper "Microbiome analyses of blood and tissues suggest cancer diagnostic approach" was retracted this past year [1].
Given the ease of contamination of tissues (and databases), I tend to be pretty skeptical of tumor microbiome claims -- especially the wide-ranging claims of microbes being present in all tumors.
