Torque teno virus (TTV) detection in aborted and slaughterhouse collected foetuses

Torque teno virus (TTV) is a non-enveloped virus with circular single-stranded DNA genome belonging to the floating genus Anellovirus. TTV was discovered in humans and later identified in other species including pigs. In pigs, two different genogroups have been described, genogroup 1 (TTV1) and genogroup 2 (TTV2). Swine TTV infection is ubiquitous and species-specifi c (1). However, its potential role on disease occurrence is yet to be defined. TTV infection has been associated with pigs affect
