We have included a new photo of M. haemolytica cultivated on purple agar (with) lactose in VetBact.
We have also included photos of S. aureus subsp. aureus, S. epidermidis and S. intermedius cultivated as streaks
on purple agar (with maltose), because it is possible to distinguish S. intermedius (1) from other Staphylococcus spp. (2-3) by this test. S. intermedius does not ferment maltose (or gives a very weak reaction) under aerobic conditions (on an agar plate) in contast to other Staphylococcus spp.
Finally, we have included a picture of a Y. enterocolitica subsp. enterocolitica colony (Fig. 77:4) cultivated on CIN agar and photographed through a microscope. The colony has the typical “bull’s eye” appearence.
