Assessment of the peste des petits ruminants (ppr) attenuated virus produced by inoculating vero cell line at different stages of cell growth

Abstract

This work presents cultural characterization of Peste Des Petites Ruminants (PPR) virus in VERO-culture. The VERO cells are currently considered as an acceptable cell substrate to produce a wide range of viruses. This study evaluates the best time for inoculation of PPR virus on VERO cell cultures; the study proved that the optimum time was 24 hours after subculture of VERO cell line using MOI 2: 1. It was also found that the best time of harvstation of virus fluid of PPR was 9th day post inoculation to reach the best titre 6 log10 TCID50 /ml.
