Abstract:
:A collection of randomly generated temperature-sensitive (ts) vaccinia virus (strain IHD-W) mutants were reported by S. Dales et al., (1978, Virology, 84, 403-428) in 1978 and characterized by electron microscopy. We have performed further genetic analysis on the Dales collection of mutants to make the mutants more useful to the scientific community. We obtained the entire Dales collection, 97 mutants, from the American Type Culture Center (ATCC). All 97 mutants were grown and reassessed for temperature sensitivity. Of these, 16 mutants were either very leaky or showed unacceptably high reversion indices even after plaque purification and therefore were not used for further analysis. The remaining 81 ts mutants were used to perform a complete complementation analysis with each other and the existing Condit collection of ts vaccinia virus (strain WR) mutants. Twenty-two of these 81 Dales mutants were dropped during complementation analysis due to erratic or weak behavior in the complementation test. Of the 59 mutants that were fit for further investigation, 30 fall into 13 of Condit's existing complementation groups, 5 comprise 3 previously identified complementation groups independent of the Condit collection, and 24 comprise 18 new complementation groups. The 59 mutants which were successfully characterized by complementation will be accessioned by and made available to the scientific community through the ATCC.
