Due to the prospect of interplanetary travel, how would you attempt to isolate and identify a bacterial infection aquired on another planet. This bacteria is unknown to use and does not appear in Bergley's or the Manual of Clinincal Microbiology.

First you need to define what is alive and what not. Then you can look for some chemicals suggesting life (nucleotides and amino acids for carbon-based life). If you were able to isolate something like that and actually grow it, the simplest thing is to sequence genome and I don't doubt that companies that will send rockets to other stars/planets will have enough money for some small sequencer. Not to mention that at that time the sequencing methods will be much more advanced.

Cis or trans? That's what matters.

1. It sais "bacterial infection", thus it's alive.
2. If it growth in humans, try all available growth media for pathogens.
3. Oxygen requirement would follow from the type of infection.
4. I would assume that isolation/id is required because antibiotics did not work. So, plate on antibiotic containing media to eliminate "earthborn" pathogens likely to be present and possibly find one it is susceptible to...
5. Once you get it to grow, you can do all standard bacterial characterization tests to describe your isolate.
6. When done and satisfied that it is not known, you can name it "Martian littleearthquake"!

OK, I see I was answering something completely different :)
