title: [Evaluation of the counterimmunoelectrophoresis technique for the serologic diagnosis of leptospirosis].
abstract: The counterimmunoelectrophoresis (CIE) technic was assessed for leptospirosis serological diagnosis by using an antigenic preparation from Leptospira biflexa Patoc I strain. It was showed that the CIE technic had 82% sensitivity and 100% specificity. The antigen used showed a gender-specific reactivity on detecting antibodies in patients infected by different leptospirosis serogroups by microagglutination test. Antigen stability for CIE technic was 6 months without loss of titre.
