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.

Immunohistochemical Distribution of Viral Antigens in Pigs Naturally Infected with Porcine Teschovirus

Journal of Veterinary Medical Science, 2008
A distribution of porcine teschovirus (PTV) antigens in pigs naturally infected with PTV is presented using the method of immunohistochemical examination. In the nervous system, PTV antigens were found in the cytoplasm of neuronal cells and glial cells distributed in the spinal ventral horn and brain stem, and also in the cytoplasm of ganglion cells in

New serotypes of porcine teschovirus identified in Shanghai, China

Archives of Virology, 2015
Teschoviruses are widely endemic and commonly found in pig fecal samples. In this study, we collected fecal specimens from various pig herds and genotyped them based on the VP1 gene. Of 322 samples, 276 were positive, giving a PTV infectivity rate of 85.7 %. PTV4 was the most common serotype found in Shanghai, followed by PTV8 and PTV10. Interestingly,

Prediction of Potential Epitopes for Peptide Vaccine Formulation Against Teschovirus A Using Immunoinformatics [PDF]

International Journal of Peptide Research and Therapeutics, 2019
Teschovirus A belongs to the family Picornaviridae and is a causal agent of the disease Teschovirus encephalomyelitis and other infections that remain asymptomatic. The present study was performed to design epitope-based peptide vaccine against Teschovirus A by identifying the potential T cell and B-cell epitopes from capsid proteins (VP1, VP3 and VP2)

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

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.

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 ...

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).

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 ...

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
