title: [Experimental study of the properties of sublines of Rickettsia prowazekii vaccinal strain E].
abstract: The instability of R. prowazekii strain E cultivated in chick embryos has been demonstrated. The complex of tests permitting determination of differences between various sublines of this strain in their immunogenic potency and residual virulence has been proposed.
