Abstract
The effects of virus input multiplicity and of tissue cell concentration upon the growth of Rift Valley fever virus in L cells (Earle) were determined. The titers obtained in suspension cultures with cells obtained from two separate laboratories were significantly different. With both monolayer culture and suspension culture systems, a virus input multiplicity of 2.5 resulted in the greatest proliferation of virus. Optimal viral yields were obtained in suspension cultures containing 4 × 105 tissue cells per ml of suspension.
