Maintaining mosquito cell lines at high temperatures: effects on the replication of flaviviruses.
The upper thermal limit for maintenance of eleven mosquito cell lines was studied. Although most cell lines could be grown at 32 degrees C to 34 degrees C, Anopheles stephensi cell line could be maintained at 37 degrees C. At higher temperatures initial growth rate was higher, but yield of cells after about a week of incubation was lower than at the standard temperature (28 degrees C). Replication of several flaviviruses in Aedes albopictus cell cultures adapted to 34.5 degrees C was faster, and viral titers were higher than at 28 degrees C.
