Molecular characterization of porcine respiratory coronavirus isolates with varying pathogenicity [PDF]

, 1994
Three new isolates of porcine respiratory coronavirus (PRCV) were isolated and characterized. Two of the PRCV isolates, AR310 and LEPP, were shown to produce moderate interstitial pneumonia, whereas the third PRCV isolate, IA1894, was only mildly ...

Next‐Generation Vaccines for Co‐Circulating PEDV and TGEV: Integrating Nucleic Acid Platforms, Mucosal Delivery, and AI–Driven Antigen Design

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Porcine epidemic diarrhea virus (PEDV) and transmissible gastroenteritis virus (TGEV) are causative agents of acute enteric diseases in pigs and have a high contagion potential. These coronaviruses (CoVs) impose substantial economic losses on global pork production, particularly affecting lactating piglets where coinfections occur. Although traditional

Unique mutations existing in open reading frame 7 (ORF7) of non-porcine transmissible gastroenteritis virus (TGEV) strains isolated in China

African Journal of Microbiology Research, 2014
Open reading frame (ORF7) of transmissible gastroenteritis virus (TGEV) plays important functions in regulating virus virulence. In this study, the ORF7s were cloned from non-porcine TGEV isolates (HYM-09, HYM-09-1 and HYM-09-2), respectively. Sequence analyses showed that there existed some new unique mutations in the three non-porcine TGEV ORF7s, and

Distribution and Regulation of RIG‐I in Porcine Intestine During TGEV and PDCoV Infection

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Transmissible gastroenteritis virus (TGEV) and porcine deltacoronavirus (PDCoV) are major enteric coronaviruses responsible for severe diarrhea in neonatal piglets. Retinoic acid‐inducible gene I (RIG‐I) is a key sensor against RNA viruses, yet its distribution in the porcine intestine and regulatory roles during TGEV and PDCoV infections remain ...

Essential Envelope Spike Motifs for Cell Entry of Transmissible Gastroenteritis Virus and Its Evolution in Coronavirus

Receptors
Background: Transmissible gastroenteritis virus (TGEV), a coronavirus (CoV) infecting pigs, uses its spike (S) glycoprotein to bind porcine aminopeptidase N (pAPN) for cell entry. Although structural studies have identified receptor-binding motifs (RBMs)

Prevalence, Genetics, and Evolution of Porcine Astrovirus 3 in China

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Porcine astrovirus 3 (PAstV3) is an emerging virus associated with porcine polioencephalomyelitis outbreaks and is frequently detected in the feces of both healthy and diarrheal pigs. Despite its significance, the prevalence, genetic characteristics, and evolutionary features of PAstV3 in China remain poorly understood.

Impact of TGEV infection on the pig small intestine

Virology Journal, 2018
Background Pig diarrhea causes high mortality and large economic losses in the swine industry. Transmissible gastroenteritis virus (TGEV) causes pig diarrhea, with 100% mortality in piglets less than 2 weeks old. No investigation has yet been made of the

Impact of genotype 1 and 2 of porcine reproductive and respiratory syndrome viruses on interferon-α responses by plasmacytoid dendritic cells [PDF]

, 2013
Porcine reproductive and respiratory syndrome (PRRS) virus (PRRSV) infections are characterized by prolonged viremia and viral shedding consistent with incomplete immunity.

Reverse Genetic Analysis of the Transcription Regulatory Sequence of the Coronavirus Transmissible Gastroenteritis Virus [PDF]

, 2004
Coronavirus discontinuous transcription uses a highly conserved sequence (CS) in the joining of leader and body RNAs. Using a full-length infectious construct of transmissable gastroenteritis virus, the present study demonstrates that subgenomic ...
