Study of the capacity of group B streptococci for causing the development of infection in mice has revealed the virulence of the cultures for mice to be determined by the serovar of the streptococcus, the infective dose, and the amount of type-specific polysaccharide. Under the conditions of mixed viral-bacterial infection, influenza A virus was shown to influence the development of bacterial infection in the animals in two ways: to increase the virulence of an avirulent strain and to decrease the pathogenicity of a virulent one in streptococcal monoinfections. Simultaneously with viral infection, the stimulation of the multiplication of an avirulent strain in the lungs of mice was observed, while in the control groups of the animals the elimination of bacteria from the lungs was registered. No additional accumulation of the infective virus in the lungs of mice in the presence of streptococci was found. |
