| co-existence of multiple strains of two novel porcine bocaviruses in the same pig, a previously undescribed phenomenon in parvoviridae and evidence for inter- and intra-host genetic diversity and recombination. | despite the recent discovery of novel bocaviruses from porcine samples, their genetic evolution and diversity are poorly understood. we report the identification and complete genome characterization of two novel parvoviruses, porcine bocavirus 3 (pbov3) and porcine bocavirus 4 (pbov4), from various porcine tissues/samples, which displayed marked intra- and inter-host genetic diversity, with recombination events. bocaviruses were detected by pcr among 16.5 % (55/333) of porcine samples (including ... | 2011 | 21632566 |
