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

open access: yesJournal 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

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.

Isolation and characterization of the first Chinese strain of porcine Teschovirus-8

Journal of Virological Methods, 2010
Investigations were carried out to identify the causal agent of acute diarrhea, respiratory distress, and death of pigs on a swine farm in Jilin Province, northern China. Only porcine Teschovirus (PTV, designated as PTV-8 Jilin/2003) was isolated from samples of organs. The presence of PTV was confirmed by the production of a specific cytopathic effect

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

open access: yesInternational 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)

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,

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 ...

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.
