| Abstract: | To investigate the prevalence of swine torque teno virus(TTV) in south China,a total of 193 tissue samples collected from 44 pig farms in south China was detected by PCR.The results showed that the positive rate for TTV1 and TTV2 infection was 41.5% and 21.8%,respectively.Co-infection rate for both TTV1 and TTV2 was 13.0%.The farm positive rate of TTV1 was 72.7% while TTV2 was 63.6%.The farm co-infection rate was 43.1%.In addition,the TTV negative rate of farm was 11.4%.Our data suggests that swine TTV widespread in south China.The TTV1 positive rate ranged from 33.3% to 57.1% and TTV2 positive rate ranged from 5% to 25.7%.Co-infection of both TTV1 and TTV2 was observed in all investigated regions except Hunan province. |
