Mastitis Media Plates
Eurofins manufactures and sells a full line of Mastitis Media Plates for On Farm and Vet Clinic/laboratory use in culturing for mastitis causing organisms. This includes both our Mastitis quad plates and mycoplasma plates. The Eurofins dairy mastitis quad plates for Staph, Strep and Gram Negatives (SSGN and SSGNC) are screening methods that aid the health providers and dairy producers in identifying the prevalence of these bacteria. Follow up therapy or sanitation strategies should be implemented in consultation with your veterinarian, herdsman and dairy co-op field man. Proper use of the Eurofins mastitis quad plates can aid the dairy producer in taking corrective action sooner.
The User Guide for the quad plates contains instructions for the SSGN (Staph, Strep and Gram Negative) plate and the SSGNC (Staph, Strep, and Gram Negative Chromogenic) plate. The bacterial growth medias in both plates are identical. The only difference is in Section 2 of the SSGNC where an enzyme substrate specific for E. coli has been added. This substrate is utilized by 95% to 97% of all E. coli isolates to stain the colonies blue or purple. An exception is E. coli 0157:H7 which does not turn blue or purple, but will give the typical pink precipitate surrounding a pink colony on both plates.
