Abstract
Forty-six arboviruses were tested for c.p.e. and/or plaque formation in an amphibian cell line. C.p.e. was observed with a high proportion of the viruses tested. Comparative plaque assay, in the XTC-2 cells at 28 °C and Vero cells at 37 °C, suggests that these systems are comparable in sensitivity and susceptibility to infection. Practical uses of this cell line are discussed.
