Yes, in its natural state it looks to be relatively harmless, however, there are mad ScientistsTM that love to gene tinker with things. It looks like when they tinker, we (including all living creatures) die.

Bdellovibrio was an example of a natural predator of the bacteria which Rothbardian was concerned about. For humans if this bacteria gets you sick more often than not your body is able to quickly take care of it but yeah if you are having issues with clearing it from your system there are medications including antibiotics for it

So it's one gram-negative bacteria taking care of another gram-negative bacteria? No need for antibiotics in such case?

Plastic-Eating Bacteria Discovered in Urban Waterways

So it is a naturally occurring environmental bacteria. Yes people can get sick from it but we have meds for it. Given that C. testosterone is a Gram-negative bacteria I would bet Bdellovibrio would take care of it. 

Since it is already out there I think if it was going to do something catastrophic it already would have.
