Section V - Antigenic Relationship and Lack of Relationship to Other Viruses
In the HI test, serum (homologous titer of 160) of virus BeAn 280577 inhibited hemagglutination by Caraparu, Apeu, Madrid and Tr 34053-1 (Caraparu-like) viruses at a dilution of 1:20.
Studies at YARU determined that Para virus was indistinguishable in PRNT and CF tests from virus strain AG80-934 isolated in Argentina (supplied by C. Calisher, CDC).
