Bacteria on the ISS have mutated and become drug-resistant

Microbiologists have studied the DNA of the bacterial species Enterobacter bugandensis, which was found on board the International Space Station in 2018. This type of microbe is not directly harmful to humans, but it could pose a potential threat. It turns out that the microorganisms have accumulated various mutations, making them functionally distinct from their earthly counterparts and resistant to known antibiotics.
