Passive protective activities of human sera against infection with strain ST67P of Staphylococcus hyicus

摘要: Five tenths ml of passive protective antibodies in 100 samples normal human sera against challenge with an encapsulated strain ST67P Staphylococcus hyicus mice were examined. Thirty three them passively protected infection S. hyicus. The activities sensitive to 2-mercaptoethanol and absorbed out either rabbit anti-human IgG, IgM or IgA serum. Also, the serum cell surface polysaccharide extracted from substance strain. When was polysaccharide, reduction contents 14.48, 19.49 33.3 percent, respectively, while 2.17, 4, 55 zero non These results indicate that specifically related globulin above polysaccharide.
