This selective agar is used at Udder Health Systems Laboratory for selection of all Staphylococci from bulk tank milk samples.
This crimson red, translucent agar is prepared from a Mannitol Salt agar base with the addition of 5% washed bovine erythrocytes. This agar has been formulated to enhance the detection of Staphylococcus aureus when present. The addition of blood to the agar provides the capability of differentiating Staphylcocci using hemolysin patterns. All suspect Staphylococcus aureus suspects should be coagulase tested. UHS Salt agar will support good growth of Staphylococci, while the salt content will inhibit most other bacteria.
This is an indicator agar used for differentiating Streptococcus uberis from other E-streps in isolates from individual cow samples. The agar is also used as a selective agar in bedding samples for the isolation of Streptococcus uberis.
