  1. (a) Percent of inoculated mice that died within three weeks after inoculation. (b) Virulence index of Cavier et al.[23] ranges from 0 (avirulent) to 16 (maximum virulence). (c) Mean volumes of subcutaneous abscesses developed six days after inoculation. (d) Clinical and pathological changes found at gynaecological and histopathological examination rated according to increasing severity from 1 to 4 as indicated in reference [2].
