Porcine teschovirus 1 (PTV-1) (Swine/CH/IMH/03) was isolated from piglets in a farm in Inner Mongolia Province, P.R. China. It was confirmed by electron microscopy, RT-PCR, and sequencing. Comparison of the sequences of the amino acid and nucleotides and phylogenetic analysis of the polyprotein showed that PTV Swine/CH/IMH/03 strain is PTV-1. The isolated virus has closest relationship with Talfan strain, they shared 98.9% and 99.5% homology of amino acids and nucleotides, respectively, in the… 

Epidemiology and molecular characterization of Porcine teschovirus in Hunan, China.

A high infection rate of PTVs circulating in asymptomatic fattening and nursery pigs is revealed, and genetic analysis of all available PTV sequences revealed that strong purifying selection and recombination play important roles in the genetic diversity and evolution of the virus.

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

The study conducted in certain farms of North India revealed that 13 of 190 fecal samples were PTV positive by RT-PCR, and a new variant of teschovirus was also identified which showed significant nucleotide diversity from the known serotypes of the tesChoviruses.

Genotyping of porcine teschoviruses isolated from 1960 to 1980 in the former Czechoslovakia and new Porcine teschovirus isolates obtained from piglets with diarrhoea

The aim of the study was retyping and reclassification of the 27 strains of porcine enteroviruses deposited in the Collection of Animal Pathogenic Microorganisms (CAPM) based on physicochemicals properties of their virions and growth characteristics.

Epidemiological study of porcine teschovirus infection in pigs at Bareilly, Uttar Pradesh, India

ABSTRACT Porcine teschoviruses (PTVs) belong to the genus Teschovirus within the family Picornaviridae had 13 serotypes linked with a variety of clinical diseases. The objective of the present study

The survey of porcine teschoviruses, porcine circovirus and porcine transmissible gastroenteritis virus infecting piglets in clinical specimens in China

The multiplex PCR assay was developed and evaluated for its ability to simultaneously detect three viral infections of swine and has the potential to be useful for routine molecular diagnosis and epidemiology.

The survey of porcine teschoviruses in field samples in China with a universal rapid probe real-time RT-PCR assay

The results indicated that the real-time RT-PCR was specific for detection of PTV with a detection limit of 10 copies/μL, but not for porcines parvovirus, porcine circovirus type 2, porCine reproductive and respiratory syndrome virus, pseudorabies virus, classical swine fever virus.

Characterization of strain PTV-2 USA/IA65463/2014 and strain PTV-11 USA/IA09592/2013 of Teschovirus A: Experimental inoculation, distribution of nucleic acids and development of Teschovirus encephalomyelitis

An experimental model was developed to determine the neuropathogenicity of the PTV-2 and P TV-11 isolates and observed that both isolates caused histological lesions and clinical disease consistent with TE in cesarean-derived colostrumdeprived pigs.
