title: Cell phenomena in experimental viral-bacterial infections in mice. II. Phagocytic activity of granulocytes during infection with influenza viruses and staphylococci.
abstract: In the paper the influence of viral, bacterial and mixed viral-bacterial infections on phagocytic activity of mouse peritoneal granulocytes was estimated. Granulocytes isolated on the 3rd, 6th, 9th and 14th day of infection were incubated for 1 h at 37 degrees C together with S. aureus 209P cultivated in the presence of 14C labelled glucose. The radioactivity of samples was measured in the scintillatory counter. The results were shown as phagocytic index of granulocytes. The obtained data point to the decrease of granulocyte phagocytic activity in mice infected with bacteria in the first period of infection. When mice were infected with non-adapted influenza virus the decrease of granulocyte phagocytic activity was observed in the late stage of infection. The infection with adapted virus as well as mixed infection led to the complete disfunction of granulocyte phagocytic activity.
