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 ...

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

The prevalence of porcine teschovirus in the pig population in northeast of China

Journal of Virological Methods, 2013
The prevalence of porcine teschovirus (PTV) in swine herds in northeast China was investigated. In 2008-2009, 1384 samples of pig sera were collected from 42 farms in Shandong, Hebei, Heilongjiang, and Jilin provinces and in Tianjin City and were tested for specific antibody against PTV-8 by immunofluorescence assay.

Identification and genotypic characterization of porcine teschovirus from selected pig populations in India

Tropical Animal Health and Production, 2019
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, 2017
Porcine 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).

Hinterhandlähmungen bei Mastschweinen im Zusammenhang mit einem neuen Stamm des porzinen Teschovirus A11

Tierärztliche Praxis Ausgabe G: Großtiere / Nutztiere, 2022
ZusammenfassungIn einem Schweinemastbetrieb in Süddeutschland konnten über einen Zeitraum von 4 Wochen Hinterhandlähmungen bei 2 Altersgruppen (50 kg sowie 60 kg) beobachtet werden. Die Morbidität bei den beiden Altersgruppen war mit 3,3 % niedrig, der Großteil der betroffenen Tiere musste jedoch aufgrund einer fortschreitenden Paralyse der ...

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

Archives of Virology, 2017
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,

Novel species of Teschovirus B comprises at least three distinct evolutionary genotypes

Transboundary and Emerging Diseases, 2019
Conventionally, Porcine teschovirus (PTV) consists of 13 genotypes (PTV 1-13, which belong to Teschovirus A); however, several novel members including PTV 14-22 have been discovered recently. PTV 21 was identified as a novel Teschovirus species named Teschovirus B.

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 ...

The underlying mechanism of Porcine Teschovirus 2 3Cpro antagonizing the NLRP3 inflammasome

Veterinary Microbiology
Porcine teschovirus (PTV) can cause diseases such as poliomyelitis, pneumonia, and reproductive disorders in sows, but research on the pathogenesis of PTV infection is limited. In this investigation, we observed that PTV infection inhibits the activation of the NLRP3 inflammasome.
