In studies by HI and CF tests of the serological reactions of 200 strains of group C virus, 199 strains reacted similarly to one of the six prototype viruses; examples are given of HI and CF reaction patterns for each type. The one exception, strain H 5546, reacted by HI like Caraparu and by CF like Oriboca and Murutucu.

These serological relationships have suggested a method of combined CF and HI techniques for the rapid identification of new group C isolates. Since 1959, 576 isolates have been identified to type by this method.
