Anyone venture to guess what kind of bacteria this is? - (Jun/23/2013 )

If you had to guess using only this picture, what would you guess this bacteria is? Does it look like any bacteria that might be found on the skin?

Streptococcus

I'd agree it's Strep. You could do a Gram stain/biochemical tests to confirm. Most common types of bacterial contamination from the skin would be Staph. epidermidis which looks a little different.

Hope this helps.
