Abstract
SummaryThe hemagglutinin and complement fixing antigen of influenza B virus were inactivated at approximately the same rate by T. pyriformis. Inactivation of virus was inversely related to the increase in protozoal population. Hemagglutinin was recoverable in low concentration from washed protozoa. The presence of additional nutrients delayed but did not prevent reduction of the viral hemagglutinin content. The hemagglutinins of influenza A virus and of Newcastle disease virus were also inactivated by actively growing cultures of T. pyriformis. The flagellates Euglena gracilis and Astasia klebsii and the ciliate Glaucoma scintillans failed to affect influenza B viral hemagglutinin.
