Torque teno virus was discovered 1997 in a serum sample from a patient with posttransfusion hepatitis of unknown etiology using representational difference analysis [14] . Since then the virus has been detected and characterised in a number of species such as primates, cats, dogs and pigs [15] , but the role of these viruses in disease development is still controversial. These viruses have small (approximately 2.8 kb) circular DNA genomes. Torque teno virus in pigs is divided into two different species, Torque teno sus virus 1 and 2, and prevalence studies have shown that TTSuV is widely spread in pig populations across the world [16, 17] . In a previous study [18] , we have found that 51.6% of a sample population of domestic pigs in Uganda were carrying one or both these TTSuV variants. Although, most studies have targeted domestic pigs, TTSuV have also been found in wild boar in Europe [19] .
