The Detection of Leptospiral Antigen in Bovine Urine by Means of a Hemolytic Reaction (UHL)

[摘要] A urine hemolytic test (UHL) for the detection of leptospiral antigen in bovine urine has been described. This procedure uses a soluble erythrocyte sensitizing substance (ESS) which was precipitated out of bovine urine during the leptospiruria period. The results obtained from calves experimentally infected with Leptospira pomona indicated that the UHL test became positive within 3 weeks postexposure. In the latter stages of the disease the presence of leptospiral antigen was demonstrated by the UHL for at least several weeks after it could no longer be detected by laboratory animal inoculation.
