Then they sequenced the entire genetic material found within these samples, hoping to find previously undiscovered bacteria species.

All in all, they found 61 bacteria species lurking within these mysterious samples.
Of those, 35 appear to have never been documented until now.
Some of the other difficult-to-identify bacteria were only recently discovered and named by other researchers.
The teams findings arepublishedthis month in the journal BMC Microbiology.
But we are stillregularly findingnovel germs out there.
Theyre also still collecting samples and finding new bacteria.
