Development of a reverse transcription loop-mediated isothermal amplification assay for detection of Porcine teschovirus [PDF]

Journal of Veterinary Diagnostic Investigation, 2011
Loop-mediated isothermal amplification (LAMP) is a sensitive method for DNA amplification. In the present report, the development of a single-tube, one-step, real-time accelerated reverse transcription (RT)-LAMP for the detection of Porcine teschovirus (PTV) is described.

Construction and characterization of the full-length cDNA of an infectious clone of emerging porcine teschovirus-2

Pathogens and Disease, 2022
Abstract Porcine teschovirus (PTV) is a causative agent of polioencephalomyelitis, encephalomyelitis, reproductive disorders and gastrointestinal and respiratory diseases in swine. In the present study, the PTV2 GX/2020 strain was isolated from pig intestinal tissue through the use of ST cells.

Development and application of a quadruplex TaqMan real-time fluorescence quantitative PCR assay for four porcine digestive pathogens [PDF]

Frontiers in Cellular and Infection Microbiology
IntroductionSalmonella, Escherichia coli, Lawsonella intracellularis, and Brachyspira hyodysenteriae are the primary pathogens responsible for gastrointestinal diseases in pigs, posing a significant threat to the health and productivity of pig production

Detection and molecular characterization of porcine enterovirus G15 and teschovirus from India

Pathogens and Disease, 2020
ABSTRACT Porcine enterovirus G (EV-G) and teschovirus (PTV) generally cause asymptomatic infections. Although both viruses have been reported from various countries, they are rarely detected from India. To detect these viruses in Western India, fecal samples (n = 26) of diarrheic piglets aged below three months from private pig farms ...

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

Detection of Porcine Teschovirus and Enterovirus Type II by Reverse Transcription–Polymerase Chain Reaction [PDF]

Journal of Veterinary Diagnostic Investigation, 2002
Porcine enteroviruses (PEVs) have been recognized as the causative agents of various clinical manifestations such as fertility disorders, neurological defects, and dermal lesions in pigs. Currently, the diagnosis of PEV infection is carried out by virus isolation, which although useful, is labor- and time-intensive.

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 ...

Prevalence of Porcine teschovirus genotypes in Hunan, China: identification of novel viral species and genotypes

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.

Characterization of PTV-12, a newly described porcine teschovirus serotype: in vivo infection and cross-protection studies

Journal of General Virology, 2017
Porcine teschoviruses (PTVs) constitute 1 of the 31 genera within the Picornaviridae family, comprising at least 13 genetic types (PTV-1 to PTV-13), of which only 11 (PTV-1 to PTV-11) have been recognized as serotypes to date. Specific for swine and wild boars, most PTVs are usually non-pathogenic, but some viral variants cause severe disorders in the ...
