Thermo Scientific™ Yersinia Selective Agar Base (Dehydrated)

Description

• Isolate and enumerate Yersinia enterocolitica from clinical specimens and food samples with Thermo Scientific™ Oxoid™ Yersinia Selective Agar Base (Dehydrated) when used with Yersinia Selective Supplement (SR0109)
• Yersinia enterocolitica is a bacterial species in the family Enterobacteriaceae that most often causes enterocolitis, acute diarrhea, terminal ileitis, mesenteric lymphadenitis, and pseudoappendicitis but, if it spreads systemically, can also result in fatal sepsis
• Yersinia Selective Agar Base and the selective supplement SR0109 have been developed specifically for the optimum growth and recovery of Yersinia enterocolitica after 18-24 hours incubation at 32°C
• The typical colonies of Yersinia enterocolitica will develop as a red bull’s-eye surrounded by a transparent border and will vary considerably among serotypes in colony size, smoothness and the ratio of the border to center diameter
• Most other organisms that are capable of growing will produce larger colonies (>2mm in diameter) with diffuse pinkish centers and opaque outer zones
• Serratia liquefaciens, Citrobacter freundii and Enterobacter agglomerans may give a colonial morphology resembling Yersinia enterocolitica
• These organisms can be differentiated from Yersinia enterocolitica by biochemical tests
