  • Method of making staphylococcus aureus vaccine
    Patent number: 5032522
    Abstract: The present invention provides an in vitro method of culturing Staphylococcus aureus to produce anti-phagocytic pseudocapsular antigens which heretofore were only produced by in vivo culturing techniques. The invention also provides a method for making a killed Stophylococcus aureus vaccine containing the anti-phagocytic pseudocapsular antigen produced in an in vitro culturing method. The anti-phagocytic pseudocapsular antigens are produced by culturing Staphylococcus aureus in a nutrient medium containing milk, milk whey and like milk products. The killed bacteria is useful for treating mastitis caused by Staphylococcus aureus.
