a model of virus-bacterial infection involving a ( pr-8/34 ) influenza virus and group b streptococcus is proposed to demonstrate the cyclic manifestations of fatal synergism of the causative agents correlating with either the cyclic detection of influenza virus antigens in the infection focus on administration of avirulent streptococcal fos4 strain , or with the time-course of activity shown by natural killers on administration of virulent streptococcal fos8 strain .
