One can easily track the source of contamination using molecular methods,
such as the automated RiboPrinter® System. It's amazing how a simple
baseline microbial flora analysis (of personnel also) can help pinpoint
where the contamination is coming from - sometimes from the most unlikely
places!

                Subject:        [PMFLIST] Staph. epidermidis

                     I have isolated Staph. epidermidis and Staph.
haemolyticus from a
                     water sample taken from a "washing machine" that
utilizes deionized
                     water.  The washing machine heats the water and we
usually recover
                     less than one CFU/ml.  This time we recovered 8.4
CFU/ml and
                     identified the organisms above.  The tech who ran the
test doesn't
                     believe it's a contamination from the test or sampling
method.  Do you
                     have any ideas where the contamination may have come
from?  I know S.
                     haemolyticus is ubiquitous, but isn't Staph epi just a
human
                     contaminate?  I'd appreciate any thoughts.
