Bats are an important natural reservoir for a variety of viral pathogens, including polyomaviruses (PyVs). The aims of this study were: (i) to determine which PyVs are present in bats in Indonesia and (ii) to analyze the evolutionary relationships between bat PyVs and other known PyVs. Using broad-spectrum polymerase chain reaction (PCR)-based assays, we screened PyV DNA isolated from spleen samples from 82 wild fruit bats captured in Indonesia. Fragments of the PyV genome were detected in 10 of the 82 spleen samples screened, and eight full-length viral genome sequences were obtained using an inverse PCR method. A phylogenetic analysis of eight whole viral genome sequences showed that BatPyVs form two distinct genetic clusters within the proposed genus Orthopolyomavirus that are genetically different from previously described BatPyVs. Interestingly, one group of BatPyVs is genetically related to the primate PyVs, including human PyV9 and trichodysplasia spinulosa-associated PyV. This study has identified the presence of novel PyVs in fruit bats in Indonesia and provides genetic information about these BatPyVs. © 2015, Springer-Verlag Wien.
