Yersinia Selective Agar is used with cefsulodin and novobiocin for the isolation of Yersinia enterocolitica in a laboratory setting. Yersinia Selective Agar is not intended for use in the diagnosis of disease or other conditions in humans.
Yersinia enterocolitica is a significant food or water borne enteric pathogen. Yersinia Selective Agar is a selective and differential medium supporting good growth of Y. enterocoliticaand some Yersinia spp. The formula is based on Cefsulodin-Irgasan-Novobiocin (CIN) Agar developed by Schiemann. In comparison with MacConkey Agar and SS Agar, Schiemann found CIN Agar provided increased inhibition of normal enteric organisms and provided improved direct recovery of Y. enterocolitica from feces. Schiemann later modified his formula to further improve growth and recovery of Y. enterocolitica.
