Origin and evolution of viroids and viroid-like satellite RNAs.

abstract：:Parvoviridae, which are classified into two subfamilies Parvovirinae and Densovirinae, can infect both vertebrate and insects and are related to a wide range of diseases in insects, animals, and humans. In this report, several new parvoviruses were identified in swine sera collected in southeastern China. The sequence...
