Abstract
Cell lines derived from human malignant melanoma tumors are susceptible to infection with varicella-zoster virus (VZV). Within 5 days after inoculation of vesicular fluid, cytopathic changes appeared in melanoma cell monolayer cultures that were incubated at either 36 or 32 degrees C. The VZV isolates at the two temperatures were serially propagated by passage of trypsin-dispersed infected cells. A plaque assay was developed utilizing melanoma cell monolayers overlaid with nutrient medium containing carboxymethylcellulose. By this assay method, the growth cycle of a VZV isolate propagated at 36 degrees C was studied and compared with that of another VZV isolate grown at 32 degrees C. With equivalent infected-cell inocula at a ratio on one inoculum cell to eight uninfected cells, the yield of cell-free virus at an incubation temperature of 32 degrees C was slightly higher than at 36 degrees C, although the peak occurred 60 h, rather than 36 h, postinfection. It was also found that the titer of low-passage VZV propagated at 36 degrees C was 0.5 to 1 log higher when assayed at 32 degrees C rather than at 36 degrees C.
