Description
This light purple opalescent agar is prepared from an inulin agar base. The agar has been formulated to differentiate Streptococcus uberis from other E-streps. Streptococcus uberis will ferment the sugar inulin, causing a background yellowing for Streptococcus uberis and no background color change for other suspect E-Strep organisms. On isolates from commercial dairy clinical specimens, this agar will differentiate Streptococcus uberis from other E-streps with a sensitivity of 94 % and specificity of 92%. The most frequently false positive inulin organism isolated from field specimens is Streptococcus bovis. UHS Inulin agar will inhibit a wide variety of fastidious microorganisms.
