title: Humoral antibody response to cattle to formalinized Staphylococcus aureus vaccine.
abstract: Five cows were inoculated intradermally with formalinized Staphylococcus aureus suspension in Freund's complete adjunvant and the development of the humoral antibody response was followed as judged by the agglutination titer of sera, at various intervals post inoculation. Highest titers were observed at 78-87 days post inoculation. Agglutinating activity was found in IgM and IgG fractions (IgG1 and IgG2) of both serum and colostrum. The agglutinating activity of colostrum was significantly higher at 12 than at 24 and 36 h, post partum. However, no such activity was detected in either normal cow serum or colostrum against S. aureus.
