Immunology of experimental staphylococcal mastitis in mice

Abstract
Anti-staphylococcal serum, inoculated intramammarily, significantly reduced the number of bacteria recovered from mammary glands in which staphylococcal mastitis had been induced. In addition, there was an alleviation of some of the pathological clinical signs following the immune-serum treatment. Intramammary inoculated normal serum and systemically inoculated immune serum failed to elicit any protection. The role of cell-mediated immunity in relation to staphylococcal mastitis was not clearly established.
