Tadpole Edema Virus: Pathogenesis and Growth Studies and Additional Sites of Virus Infected Bullfrog Tadpoles
Considering geographic origin, method of isolation, and the life stage, health and host species, the polyhedral cytoplasmic amphibian viruses thus far cultured belong to one of three categories. The first category consists of viruses obtained directly from adult Rana pipiens—with or without renal adenocarcinoma—either from northcentral United States or from New England and adjacent Canada (1, 2, 3, 4). The second category comprises viruses from larval or adult Diemictylus viridescens (formerly, Triturus viridescens) from New England or southeastern United States—efts previously inoculated with New England R. pipiens kidney tumor cells (4, 5) and more recently virus has been isolated directly from newts (6). The third category is a group of viruses isolated directly from normal adult or normal and diseased tadpoles of Rana catesbeiana from northcentral or southeastern United States (7).
