AN OBSERVATION OF BIOLOGICAL PROPERTIES OF ORTHOMYXOVIRUSES TYPE A IN THE CONDITION OF SYMBIOSIS / 西安交通大学学报(医学版)

ABSTRACT

This report concerns an observation on the biological properties of orthomyxoviruses type A in the condition of symbiosis with streptococcus A in embryonated eggs. The results show that both the viruses and the streptococci multiply normally in the condition of symbiosis and that the activity of the virus neuraminidase enhances, with the speed of the virus disassociating from RBC increasing. The morphological changes of the virus were observed also by transmission electron microscopy. The reason of these changes is discussed,
