Interesting blog post and paper from Tara Smith. Her lab did some characterization of samples from kids and workers in childcare settings. As part of their work they found some interesting varieties of Staphylococcus aureus. For more detail see her post here: New paper: Staphylococcus aureus ST398 in a childcare worker : Aetiology. If you have not seen her blog it is worth checking out. Lots of interesting microbiology there.
