Simultaneous infection with distinct strains of Torque teno sus virus (TTSuV) in healthy slaughter-age pigs

Simultaneous infection with distinct strains of Torque teno sus virus (TTSuV) in healthy... The aims of this study were to evaluate torque teno sus virus (TTSuV) infection in healthy slaughter-age pigs and to compare the similarities of the untranslated region (UTR) nucleotide (nt) sequences obtained from different biological samples of the same animals. Fifty-eight pigs were evaluated by PCR assay for the presence of TTSuV in paired samples of liver and serum (Group 1, n = 27) and lung and serum (Group 2, n = 31). All the pigs were positive for TTSuV infection in the organs sampled and 94.8 % (n = 55) presented with viraemia. The nt sequence similarities between the Groups 1 and 2 varied from 91.7 % to 96.6 % (TTSuV1) and 91 % to 95 % (TTSuV2). In Group 1, the nt sequence similarities were 93 % (TTSuV1) and 95.4 % (TTSuV2). In Group 2, the nt sequence similarities were 95 % (TTSuV1) and 91 % (TTSuV2). These results revealed the simultaneous infection with distinct strains of TTSuV1 and 2 in healthy pigs at slaughter age. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Veterinary Research Communications Springer Journals

Abstract

The aims of this study were to evaluate torque teno sus virus (TTSuV) infection in healthy slaughter-age pigs and to compare the similarities of the untranslated region (UTR) nucleotide (nt) sequences obtained from different biological samples of the same animals. Fifty-eight pigs were evaluated by PCR assay for the presence of TTSuV in paired samples of liver and serum (Group 1, n = 27) and lung and serum (Group 2, n = 31). All the pigs were positive for TTSuV infection in the organs sampled and 94.8 % (n = 55) presented with viraemia. The nt sequence similarities between the Groups 1 and 2 varied from 91.7 % to 96.6 % (TTSuV1) and 91 % to 95 % (TTSuV2). In Group 1, the nt sequence similarities were 93 % (TTSuV1) and 95.4 % (TTSuV2). In Group 2, the nt sequence similarities were 95 % (TTSuV1) and 91 % (TTSuV2). These results revealed the simultaneous infection with distinct strains of TTSuV1 and 2 in healthy pigs at slaughter age.
