∗ Positivity is ascertained when a MAT reaction is observed solely to this serovar or when this serovar displays a titer three times higher than the other serovars when cross reactions is observed. ∗∗ Cross reactions in which the previous parameters are not observed (in all these reactions, MAT titer against a member of the Sejroe serogroup was common). AUS: australis, GRIPP: grippotyphosa, IH: icterohaemorrhagiae, SJ: sejroe.
