Leptospiral Macroscopic Agglutinating Antigens

Abstract
A method for the prepn. of macroscopic leptospiral antigens is descr. Antigens of this type have been prepd. from 9 leptospiral sero-types. Cross reaction patterns are essentially comparable to those observed in the agglutination-lysis technic. Antigens so prepd. are sensitive, specific, and stable under protracted periods of storage, and produce easily discernible reactions in the presence of antibodies.
