TCN2 and infection: Of those animals that had isolates genotyped as TcII by mini-exon typing (TcII, TcV or TcVI) a high proportion reacted with the epitope common to TcII, TcV and TcVI (11/20 excluding non-specific reactors) while seven of these 11 also reacted with TSSApep-V/VI, representing infection with a hybrid lineage TcV or TcVI.
