Mastitis, or inflammation of the mammary gland, is a production-limiting infection that remains one of the most common and costly diseases in dairy herds. More than 200 different pathogens have been found to cause mastitis in dairy cattle (Blowey and Edmondson 2010). Due to the high treatment costs associated with mastitis, farmers may find value in identifying these mastitis-causing pathogens and then determining the appropriate management decision such as treatment, culling, segregation, and prevention. Milk culturing can be an effective tool for isolating and identifying organisms as well as for providing a snapshot of a herd’s mastitis pathogen status.
