The other day, one of my commenters stated that "a well-informed sixth-grader should be able to distinguish between MRSA and E. coli".

Here's a nutrient agar plate with some of the bacteria that we isolated from a local creek last fall. We identified our bacteria by sequencing the 16S ribosomal DNA, but for various reasons, that I won't go into here, we don't know which sequences belong to which colonies.

I guess we need some well-informed sixth graders. ;-)
