    • Environmental Streptococci and Enterococcus spp.: A Practical Summary for Controlling Mastitis 

      Petersson-Wolfe, Christina S.; Currin, John F. (Virginia Cooperative Extension, 2012-07-12)
      Many milk culture laboratories across the United States do not distinguish between environmental streptococci and Enterococcus spp. However, this document will address the inherent differences between these pathogens as ...
    • Escherichia coli: A Practical Summary for Controlling Mastitis 

      Petersson-Wolfe, Christina S.; Currin, John F. (Virginia Cooperative Extension, 2011-07-29)
      Escherichia coli are Gram-negative bacteria, similar in structure to Klebsiella spp. E. coli mastitis is typically associated with a quick onset and often severe clinical signs.
    • Klebsiella spp.: A Practical Summary for Controlling Mastitis 

      Petersson-Wolfe, Christina S.; Mullarky, Isis K.; Currin, John F. (Virginia Cooperative Extension, 2011-07-29)
      Klebsiella spp. are environmental organisms. The most common, mastitis-causing species are Klebsiella pneumoniae and K. oxytoca, but treatment and control is similar for all species of Klebsiella.

    • Serratia spp.: A Practical Summary for Controlling Mastitis 

      Petersson-Wolfe, Christina S.; Costello, Sandy; Currin, John F. (Virginia Cooperative Extension, 2011-07-29)
      Serratia spp. are Gram-negative bacteria that are similar in structure to Escherichia coli and Klebsiella spp. Serratia is resistant to most antibiotics; therefore, cure rates are very limited.
    • Staphylococcus aureus: A Practical Summary for Controlling Mastitis 

      Petersson-Wolfe, Christina S.; Mullarky, Isis K.; Currin, John F. (Virginia Cooperative Extension, 2011-07-29)
      Staphylococcus aureus (S. aureus) mastitis is extremely difficult to control by treatment alone. To date, successful control is gained only through prevention of new infections and culling of infected animals.
    • Streptococcus agalactiae: A Practical Summary for Controlling Mastitis 

      Petersson-Wolfe, Christina S.; Currin, John F. (Virginia Cooperative Extension, 2012-07-19)
      Strep. agalactiae is a contagious mastitis pathogen spread from cow to cow at milking. Proper milking procedures, including the use of efficacious pre- and post-milking teat disinfectants, will help to reduce the number ...
    • Streptococcus dysgalactiae: A Practical Summary for Controlling Mastitis 

      Petersson-Wolfe, Christina S.; Currin, John F. (Virginia Cooperative Extension, 2012-07-12)
      Streptococcus dysgalactiae is considered both a contagious and an environmental pathogen. These organisms can spread from cow to cow at milking time and are also commonly found in the cow's environment.
