Reproduction of mumps virus strains in Vero cell cultures at 32, 37 and 40 degrees C.

Reproduction of various mumps virus strains was studied in Vero cell tube cultures at 32, 37 and 40 degrees C. Strains of different character could be distinguished based on temperature dependence of their reproduction, but results of several repeated experiments had to be taken into account. The problem of a suitable numerical marker was discussed along with the relationship between temperature dependence of reproduction of a strain and the host response to its action in vivo.
