A sensitive method for quantification of vesicular stomatitis virus defective interfering particles: focus forming assay

, : A sensitive method for quantification of vesicular stomatitis virus defective interfering particles: focus forming assay. Journal of General Virology 48(1): 237-240

A focus-forming assay for the quantification of defective interfering (DI) particles of vesicular stomatitis virus (VSV) is described. This assay is based on the procedures described for lymphocytic choriomeningitis (LCM) virus by Popescu et al. (1976). Under appropriate conditions this focus-forming assay can quantify fewer than 100 DI particles/ml in a preparation containing a large number of infectious particles.

All animals are vulnerable to predation at some point in their lives and consequently prey organisms often develop effective risk assessment systems. For many aquatic species predation risk assessment occurs through the use of olfactory cues, incl...
