Growth and purification of enteric adenovirus type 40

The enteric adenoviruses of subgroup F (Ad40 and Ad41) pose some special problems of cultivation, as they cannot be readily passaged in many of the cell types used to propagate the more commonly used subgroup C serotypes (Ad2 and Ad5) and there is no standard plaque assay. Methods to propagate Ad40 in complementing cell lines and to evaluate infectivity and particle number are presented in this chapter.
