A rare new microbe has been found in two different clean rooms, one in Florida and the other in South America.

This population of berry-shaped bacteria is so different from any other known bacteria, it has been classified as not only a new species, but also a new genus, the next level of classifying the diversity of life. Its discoverers named it Tersicoccus phoenicis. Tersi is from Latin for clean, like the room. Coccus, from Greek for berry, describes the bacterium’s shape. The phoenicis part is for NASA’s Phoenix Mars Lander, the spacecraft being prepared for launch in 2007 when the bacterium was first collected by test-swabbing the floor in the Florida clean room.

Some other microbes have been discovered in a spacecraft clean room and found nowhere else, but none previously had been found in two different clean rooms and nowhere else. Home grounds of the new one are about 2,500 miles (4,000 kilometers) apart, in a NASA facility at Kennedy Space Center and a European Space Agency facility in Kourou, French Guiana.

Unlike the bacteria found on ISS, this microbe does not appear to pose any specific health problem. It does provide biologists with a good example of the kind of life that might survive in hostile environments like Mars.

    Sounds like these hardy guys are normally present in very low numbers but flourish when competing bacteria are killed off.

    That is the problem with antibiotics, you kill off a strain of bacteria that kept another strain of bacteria in check, this happens all throughout nature and is a problem for humans to face up to in the wake of these super strains that seem to run unchecked now.
