Torque teno virus from Korean domestic swine farms, 2017-2018.

ABSTRACT:

Background

Torque teno viruses (TTVs) have been detected worldwide, from a wide range of animals. Up to date, few studies focused on the prevalence of TTVs in general and swine torque teno viruses (TTSuVs) in particular in Korean swine farms.

Objective

This study aimed to investigate the appearance of TTSuVs and TTVs in sick pigs during the 2017-2018 period.

Materials and methods

Molecular-based method using TTSuV1-, TTSuV2- and TTV3-specific primers was used to screen for the viruses from either sera or pooled internal organs of sick pigs. For genetic characterization, genomic sequences of TTVs were sequenced by a primer walking method. Several bioinformatic tools have been utilized to investigate the genomic organization and genetic relationship of TTVs.
