Porcine tissues were screened for the presence of Adeno-Associated Viruses (AAV). Several AAV sequences were isolated from various porcine tissues, and BLAST analysis confirmed high to low homology with known AAV sequences of different origin. Sequence analysis confirmed the isolation of at least three novel porcine AAV isolates which we named AAVpo1, -po2, and -po3. Novel AAVs derived from porcine tissues may significantly contribute to the generation of new preventive or curative clinical modalities acceptable for human use.
