Will bacteria or virus be able to survive in mars?

there was a unmanned moon mission a couple of years before the manned, I'm not sure of the timespan. I think someone else can build on it.but anyway the astronauts went to this vehicle and pulled the camera lens, took it back, swabbed it and found that some one contaminated the interior with a sneeze or something. They fed it and sure enouph bacteria sprang up ready to rock. Gives you the spooks don't it

Will bacteria or virus be able to survive in mars?
We judge life and life forms by our standards . Here on earth freezing cold or extreme high temps kill most bacteria but thats here . Not life from some other enviroment that may have evolved differently and as far as Virus's they can exhist in far greater extremes.
Reply:if we can so can they
Reply:Sure they will.Viruses and bacteria can live in a condition where there is no oxygen,no water or even in space.
Reply:No, i don't think so!!
Reply:according to many scientists, bacteria and viruses are probably not able to be sustainable on the martian surface, but thoughts are that since mars once supported life a question is still unanswered whether underneath the surface of mars bacteria or traces of life may have survived. to many it is a goal to find out
Reply:Yes, why not...bacterial and viruses can grow at any timperature...the kind of bacteria found on mars would be definately differnent from earth.
Reply:They found evidence of bacteria on Mars in 1997 I guess that answers that.
Reply:Yes the can . there are types of microbes that do not need oxygen but use So2 and other gasses for anaerobic energy . these types of microorganism can be sent to a planet and start altering ts atmosphere . in a period of time the atmosphere may be able to sustain other forms of organisms like algae which can be sent later in the process .on the long term the plant can be inhabited
Reply:ya viruses might survive on mars and i don know about bacteria
Reply:they can because when the earth was young and just millions of years old, earth was like mars and viruses and bacteria lived through it.
