Pathological Changes in Pigs Experimentally Infected with Porcine Teschovirus

Journal of Comparative Pathology, 2009
Nonsuppurative encephalomyelitis with neurological signs expressed as flaccid paralysis of the hindlimbs was experimentally induced in three-week-old piglets by a single intravenous injection of the Toyama 2002 strain of porcine teschovirus (PTV) isolated from field pigs in Japan.

The urinary shedding of porcine teschovirus in endemic field situations

Veterinary Microbiology, 2016
Porcine teschoviruses (PTVs) belong to the genus Teschovirus within the family Picornaviridae. PTVs are universal contaminants in pig herds in endemic and multi-infection statuses. Previous research has demonstrated PTV antigens and nucleic acid in renal glomeruli and tubular epithelia, suggesting the possibility that PTVs might be shed and transmitted

Immunohistochemical Detection of Porcine Teschovirus Antigen in the Formalin‐fixed Paraffin‐embedded Specimens from Pigs Experimentally Infected with Porcine Teschovirus

Journal of Veterinary Medicine Series A, 2007
SummaryPorcine teschovirus (PTV) antigens were detected by a streptavidin‐biotin complex method in formalin‐fixed paraffin‐embedded tissues of 3‐week‐old pigs that had been inoculated intravenously with PTV Talfan strain. PTV antigens were detected in cytoplasm of nerve cells, glial cells and endothelial cells in the cerebellar nuclei, the grey matter ...

Multiple models of porcine teschovirus pathogenesis in endemically infected pigs

Veterinary Microbiology, 2014
Porcine 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 ...

A Piglet with Concurrent Polioencephalomyelitis due to Porcine Teschovirus and Postweaning Multisystemic Wasting Syndrome

Journal of Veterinary Medical Science, 2008
A piglet developed respiratory distress followed by difficulty in standing and unsteady gait. The lesions were characterized by polioencephalomyelitis with the predominant distribution in the brain stem, as well as lymphocyte depletion and histiocyte infiltration with cytoplasmic inclusion bodies in the lymphoid tissues throughout the body and ...

Porcine teschovirus 2 induces an incomplete autophagic response in PK-15 cells

Archives of Virology, 2018
Autophagy 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,

Isolation of serotype 2 porcine teschovirus in China: Evidence of natural recombination

Veterinary Microbiology, 2010
Porcine 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.

Teschovirus encephalomyelitis - Current state of knowledge

Medycyna Weterynaryjna, 2009
<p>Teschovirus encephalomyelitis of pigs is an enzootic disease caused by neurotropic Porcine teschovirus serotype 1 (PTV-1). This disease occurs exclusively in pigs. Teschovirus encephalomyelitis was first described in Czechoslovakia in 1929.

Metagenomic identification and sequence analysis of a Teschovirus A-related virus in porcine feces in Japan, 2014-2016.

Infection, Genetics and Evolution, 2018
Porcine Teschoviruses (PTVs) are associated with polioencephalomyelitis and various diseases, including reproductive and gastrointestinal disorders, of pigs and wild boars, and are also detected in the feces of healthy pigs.
