Abstract: An antigenic composition is derived from surface extracted protein of cell wall surfaces and the culture supernatant extract of Staphylococci. The strain is highly virulent and &bgr; hemolytic on blood agar plate. They are mixed and purified by ion exchange and gel filtration column chromatography. This preparation method can be used in all Gram-positive bacilli. The antigens, having molecular weight of about 10,000-70,000 are certain kinds of glycoprotein comprising proteins (ca. 10-20%) and carbohydrates (ca. 75-90%). They are extracted from the cells with the use of a hypertonic buffer solution of pH 6.5-8.5 at a temperature below the denaturing point of the antigenic protein, and are salted out with ammonium sulfate (ca. 65-85%). The culture supernatant is extracted in the same way by salting out with ammonium sulfate (ca. 65-85%). The antigen fraction from both cell wall and culture supernatant is obtained in such an operation. The antigen can be used as a preparation antigen to Staphylococcus antigen.

Abstract: In a mastitis progression data memory 80 there is previously recorded data on the corresponding relationship between the state of progression of mastitis caused by bacteria and the trace light intensity chemically emitted by phagocytic leukocytes in milk when they phagocytose the bacteria, the trace light intensity chemically emitted by the phagocytic leukocytes in the milk is detected by a photodetector 41a, the state of progression of mastitis corresponding to the light intensity is diagnosed by an extractor/converter 13 with reference to the mastitis progression data memory 80 based on the detected trace light intensity, and the diagnosed state of progression of mastitis is outputted by output means 30. It is possible to conveniently and reliably diagnose the state of progression of mastitis from invasion of bacteria up to severe mastitis.
