| [the immunochemical and biological properties of leptospira membranes]. | the immunochemical and biological properties of purified membrane fractions obtained from leptospira interrogans, serovar copenhageni, strain rat 2, and leptospira biflexa, strain patoc 1, were studied. the presence of genus-specific and group-specific antigens in leptospiral membranes was established by the methods of immunodiffusion analysis, the microagglutination (ma) and lysis tests. in animal experiments cell membrane preparations produced no toxic and allergic effects. leptospiral membran ... | 1992 | 1301663 |
