Description
Using three cases of clinical Staphylococcal mastitis and two clinically normal cases infected with staphylococci, we investigated correlation between Staphylococcal enterotoxin-C (SEC) and Toxic-shock syndrome toxin-1 (TSST-1) and correlation between specific antibody titers against these toxins in mammary-gland secretions (MGS) and the onset of mastitis. In the cases of clinical mastitis, concentrations of SEC in MGS peaked during the period immediately before onset and onset itself. Somatic cell counts increased after SEC concentration reached a maximum. No SEC was detected in MGS during the lactating period in clinically normal cases. Immediately after parturition, in clinically normal cases, concentration of SEC in MGS was less than in the same udder after the onset of clinical mastitis. TSST-1 concentrations were at the same level in both mastitic and normal cases. In all cases, titers of specific antibodies against TSST-1 in MGS were higher than those against SEC. These results suggest that increased SEC in MGS was an important pathogenic factor in the three cases of clinical mastitis.
