Journal of General Virology, 2018 Porcine teschovirus (PTV) comprises at least 13 genotypes (PTV 1-13). Here, the genotypes of field strains prevalent among pig populations in Hunan Province, China, were identified. Multiple PTV genotypes, including all genotypes except PTV 7 and 8, were found co-circulating in the pig populations, reflecting a high genetic diversity.

Isolation of serotype 2 porcine teschovirus in China: Evidence of natural recombination
Veterinary Microbiology, 2010Porcine teschovirus (PTV), the pathogen of porcine polioencephalomyelitis, is a member of the family Picornaviridae. In this study, a new PTV strain (designated as JF613) was isolated from pigs in China. It was confirmed by the specific CPE on susceptible cells, RT-PCR and nucleotide sequencing.

Multiple models of porcine teschovirus pathogenesis in endemically infected pigs
Veterinary Microbiology, 2014Porcine teschoviruses (PTVs) belong to the genus Teschovirus within the family Picornaviridae. PTVs are universal contaminants in pig herds in endemic and multi-infection status. To further the understanding of PTV pathogenesis in endemically infected pigs, a set of samples was studied by real time reverse transcription PCR (qRT-PCR) to quantitate ...

Porcine teschovirus (PTV) previously classified as porcine enteroviruses in the family Picornaviridae are associated with a wide range of illnesses in swine ranging from asymptomatic infection to acute fatal encephalomyelitis, diarrhea, and pneumonia. This study was planned to investigate whether porcine teschovirus is prevalent among pigs in India and

Epidemiology and molecular characterization ofPorcine teschovirusin Hunan, China
Transboundary and Emerging Diseases, 2017Porcine teschoviruses (PTVs) have been shown to be widely distributed in pig populations. In this study, 261 faecal and 91 intestinal content samples collected from pigs at 29 farms in Hunan, China, were tested for the presence of PTV by reverse transcription-polymerase chain reaction (RT-PCR).

Porcine teschovirus 2 induces an incomplete autophagic response in PK-15 cells
Archives of Virology, 2017Autophagy is a homeostatic process that has been shown to be vital in the innate immune defense against pathogens. However, little is known about the regulatory role of autophagy in porcine teschovirus 2 (PTV-2) replication. In this study, we found that PTV-2 infection induces a strong increase in GFP-LC3 punctae and endogenous LC3 lipidation. However,

There are concerns about the zoonotic transmission of viruses through undercooked pork products. There is a lack of information on suitable indicator viruses for fecal contamination with pathogenic enteric viruses in the meat processing chain. The study compared the incidence and levels of contamination of hog carcasses with F-coliphages, porcine ...

Genetic Characterization and Pathology of Porcine Teschovirus (PTV) in India
Indian Journal of Animal ResearchBackground: The porcine teschovirus (PTV) is common swine pathogen which causes a wide range of illnesses ranging from asymptomatic infection to acute fatal encephalomyelitis, diarrhoea and pneumonia. Despite of its economical importance very limited studies are available on the pathology of PTV.

A porcine teschovirus (PTV) was isolated from a dead piglet from a herd of 200 sows showing reproductive failure in Fuyu, Heilongjiang Province, China. Sequencing of most of the genome of this isolate, designated Fuyu/2009, revealed that is was a PTV-8 isolate, closely related to a previously identified Chinese PTV-8 strain (Jilin/2003).

Survival of Porcine teschovirus as a surrogate virus on pork chops during storage at 2 °C
International Journal of Food Microbiology, 2015Due to the lack of an efficient cultivation system, little is known about the stability and inactivation of hepatitis E virus (HEV). In addition, there is a lack of information on which cultivable virus(es) are suitable as model or surrogate viruses for HEV.
