Detection of swine Torque teno virus genogroups 1 and 2 in boar sera and semen
چکیده انگلیسی

Torque teno virus (TTV) is a non-enveloped, circular, single-stranded DNA virus infecting swine and several other species. TTV is nowadays considered a non-pathogenic virus in all species where it has been found. In the present study, the prevalence of two distinct swine TTV genogroups in boar semen and sera was determined by a nested PCR method. Furthermore, association between TTV infection and semen qualitative and quantitative parameters was analyzed. TTV was detected in 74% of boar sera and 72% in semen. The prevalence of genogroup 1 in sera and semen were 64% and 55%, respectively, while lower prevalence of genogroup 2 was observed in both sera (38%) and semen (32%). Some significant associations of TTV infection on semen characteristics in boar genetic lines were observed, but qualitative and quantitative semen parameters obtained in studied boars fall into normal expected ranges. Therefore, TTV semen infection was not evidenced to be harmful for the studied qualitative and quantitative parameters of semen. The high rate of TTV in semen suggests that sexual route might contribute to the transmission of the virus. It is presently unknown if this potential vertical transmission of swine TTV implies any effect on female reproductive tract. This study also represents the first description of swine TTV presence in semen.
