Torque teno virus: new discoveries during 2009

Torque teno virus (TTV) is a single-stranded DNA virus that has been detected in serum of primate and non-primate species including swine. Little information on swine TTV infection and transmission dynamics is nowadays available. Five papers published during 2009 describe the latest results obtained by the swine TTV group at CReSA.

TTVs are vertebrate infecting, single-stranded circular DNA viruses. Two genetically distinct TTV genogroups (TTV1 and TTV2) infect swine worldwide with high prevalence. Currently, swine TTVs are considered non-pathogenic, although TTV2 has been linked to post-weaning multisystemic wasting syndrome, a porcine circovirus disease .

Research on swine TTV at CReSA has been carried out since 2006. During 2009 the group has published five papers based on the results obtained. Below the main results of these papers are summarized:
