The distribution of HI titres by human native MBL against clinical isolates of influenza viruses from 1990 to 1995 in Osaka, Japan. The HI test was performed by the microtitre tray method with 1% chick red blood cell suspension, ether-treated egg-derived virus antigen of each strain, and dilutions of MBL. The HI value shows the lowest concentration (μg/ml) of human MBL causing HI.
