Differences in Infectivity of Neurotropic Viruses Incubated in Distilled Water, Isotonic NaCl and Hypertonic NaCl.

Abstract
Three groups of neurotropic viruses were found to differ in their stability, as judged by infectivity for mice, when diluted in DW, isotonic and hypertonic saline and held at 37[degree]C for 1 hour. Mouse encephalomyelitis (GDVH, FA) was stable in all 3 diluents. EMC virus (Mengo, MM) lost infectivity in isotonic NaCl only. Arbor viruses lost infectivity in all 3 diluents.
