New colony photos of Staphylococcus aureus

Staphylococcus aureus subsp. aureus

Staphylococcus aureus subsp. aureus

We’ve added some new images in the last couple of days, including some nice colony photos of S. aureus subsp. aureas where the double hemolytic zones are clearly visible. The clear α-hemolysis is indicated with the black arrow and the diffuse β-hemolysis is indicated with the blue arrow.

    These new images are really good! I agree with Annettes comment on the post before that colony pictures can be very useful, and this is especially true for hemolytic bacteria. Students always ask questions about different kind of hemolysis on blood agar.

    On my wish list for the future is an image quiz, optimally with a combination of macroscopic and microscopic pictures.
