[A comparative study of the immunological indices in guinea pigs administered an inactivated Marburg virus].

Abstract

Samples of concentrated and unconcentrated preparations of Marburg virus were studied. The ultrafiltration method helped increase the specific protein content and decrease the common protein content in a preparation. The resistance index increased with an increase of the specific protein content and the maximum (2.63 +/- 0.2) was reached by two immunizations on 0 and 14 days.
