The major product of porcine transmissible gastroenteritis coronavirus gene 3b is an integral membrane glycoprotein of 31 kDa. (1/203)

The open reading frame potentially encoding a polypeptide of 27.7 kDa and located as the second of three ORFs (gene 3b) between the S and M genes in the genome of the Purdue strain of porcine transmissible gastroenteritis coronavirus (TGEV) was cloned and expressed in vitro to examine properties of the protein. Gene 3b has a postulated role in pathogenesis, but its truncated form in some laboratory-passaged strains of TGEV has led to the suggestion that it is not essential for virus replication. During synthesis in vitro in the presence of microsomes, the 27.7-kDa polypeptide became an integral membrane protein, retained its postulated hydrophobic N-terminal signal sequence, and underwent glycosylation on apparently two asparagine linkage sites to attain a final molecular mass of 31 kDa. A 20-kDa N-terminally truncated, nonglycosylated, nonanchored form of the protein was also made via an unknown mechanism. The existence of both transmembrane and soluble forms of the gene 3 product in the cell is suggested by immunofluorescence patterns showing both a punctuated perinuclear and diffuse intracytoplasmic distribution. No gene 3b product was found on gradient-purified Purdue TGEV by a Western blotting procedure that would have detected as few as 4 molecules/virion, indicating the protein probably is not a structural component of the virion.  (+info)

Evaluation of the baculovirus-expressed S glycoprotein of transmissible gastroenteritis virus (TGEV) as antigen in a competition ELISA to differentiate porcine respiratory coronavirus from TGEV antibodies in pigs. (2/203)

The spike (S) glycoprotein of the Miller strain of transmissible gastroenteritis virus (TGEV) was recently cloned and expressed in baculovirus. The recombinant S protein was used as the coating antigen in a competition (blocking) enzyme-linked immunosorbent assay (ELISA) in combination with monoclonal antibodies to the S protein epitope A (conserved on TGEV and porcine respiratory coronavirus [PRCV]) or epitope D (present on TGEV only) to differentiate PRCV- from TGEV-induced antibodies. One set (set A) of 125 serum samples were collected at different times after inoculation of caesarean-derived, colostrum-deprived (n = 52) and conventional young pigs (n = 73) with 1 of the 2 porcine coronaviruses or uninoculated negative controls (TGEV/PRCV/negative = 75/30/20). A second set (set B) of 63 serum samples originated from adult sows inoculated with PRCV and the recombinant TGEV S protein or with mock-protein control and then exposed to virulent TGEV after challenge of their litters. Sera from set A were used to assess the accuracy indicators (sensitivity, specificity, accuracy) of the fixed-cell blocking ELISA, which uses swine testicular cells infected with the M6 strain of TGEV as the antigen source (ELISA 1) and the newly developed ELISA based on the recombinant S protein as antigen (ELISA 2). The sera from set B (adults) were tested for comparison. The plaque reduction virus neutralization test was used as a confirmatory test for the presence of antibodies to TGEV/PRCV in the test sera. The accuracy indicators for both ELISAs suggest that differential diagnosis can be of practical use at least 3 weeks after inoculation by testing the dual (acute/convalescent) samples from each individual in conjunction with another confirmatory (virus neutralization) antibody assay to provide valid and complete differentiation information. Moreover, whereas ELISA 1 had 10-20% false positive results to epitope D for PRCV-infected pigs (set A samples), no false-positive results to epitope D occurred using ELISA 2, indicating its greater specificity. The progression of seroresponses to the TGEV S protein epitopes A or D, as measured by the 2 ELISAs, was similar for both sets (A and B) of samples. Differentiation between TGEV and PRCV antibodies (based on seroresponses to epitope D) was consistently measured after the third week of inoculation.  (+info)

Targeted recombination demonstrates that the spike gene of transmissible gastroenteritis coronavirus is a determinant of its enteric tropism and virulence. (3/203)

Targeted recombination within the S (spike) gene of transmissible gastroenteritis coronavirus (TGEV) was promoted by passage of helper respiratory virus isolates in cells transfected with a TGEV-derived defective minigenome carrying the S gene from an enteric isolate. The minigenome was efficiently replicated in trans and packaged by the helper virus, leading to the formation of true recombinant and pseudorecombinant viruses containing the S proteins of both enteric and respiratory TGEV strains in their envelopes. The recombinants acquired an enteric tropism, and their analysis showed that they were generated by homologous recombination that implied a double crossover in the S gene resulting in replacement of most of the respiratory, attenuated strain S gene (nucleotides 96 to 3700) by the S gene of the enteric, virulent isolate. The recombinant virus was virulent and rapidly evolved in swine testis cells by the introduction of point mutations and in-phase codon deletions in a domain of the S gene (nucleotides 217 to 665) previously implicated in the tropism of TGEV. The helper virus, with an original respiratory tropism, was also found in the enteric tract, probably because pseudorecombinant viruses carrying the spike proteins from the respiratory strain and the enteric virus in their envelopes were formed. These results demonstrated that a change in the tropism and virulence of TGEV can be engineered by sequence changes in the S gene.  (+info)

Structural maturation of the transmissible gastroenteritis coronavirus. (4/203)

During the life cycle of the transmissible gastroenteritis coronavirus (TGEV), two types of virus-related particles are detected in infected swine testis cells: large annular viruses and small dense viruses. We have studied the relationships between these two types of particles. Immunoelectron microscopy showed that they are closely related, since both large and small particles reacted equally with polyclonal and monoclonal antibodies specific for TGEV proteins. Monensin, a drug that selectively affects the Golgi complex, caused an accumulation of large annular viral particles in perinuclear elements of the endoplasmic reticulum-Golgi intermediate compartment. A partial reversion of the monensin blockade was obtained in both the absence and presence of cycloheximide, a drug that prevented the formation of new viral particles. After removal of monensin, the Golgi complex recovered its perinuclear location, and a decrease in the number of perinuclear large viral particles was observed. The release of small dense viral particles into secretory vesicles and the extracellular medium was also observed, as was a partial recovery of infectivity in culture supernatants. Small viral particles started to be seen between the third and the fourth Golgi cisternae of normally infected cells. All of these data strongly indicate that the large annular particles are the immature precursors of the small dense viruses, which are the infectious TGEV virions. The immature viral particles need to reach a particular location at the trans side of the Golgi stack to complete their morphological maturation.  (+info)

Characterization of the sialic acid binding activity of transmissible gastroenteritis coronavirus by analysis of haemagglutination-deficient mutants. (5/203)

Transmissible gastroenteritis coronavirus (TGEV) agglutinates erythrocytes of several species by virtue of sialic acid binding activity of the surface protein S. We have isolated and characterized five haemagglutination-defective (HAD) mutants. In contrast to the parental virus, the mutants were unable to bind to porcine submandibulary mucin, a substrate rich in sialic acid. Each of the mutants was found to contain a single point mutation in the S protein (Cys155Phe, Met195Val, Arg196Ser, Asp208Asn or Leu209Pro), indicating that these amino acids are affecting the sialic acid binding site. In four of the HAD mutants a nearby antigenic site is affected in addition to the sialic acid binding site, as indicated by reactivity with monoclonal antibodies. The parental virus was found to have an increased resistance to the detergent octylglucoside compared to the HAD mutants. This effect depended on cellular sialoglycoconjugates bound to the virion. If the binding of sialylated macromolecules was prevented by neuraminidase treatment, the parental virus was as sensitive to octylglucoside as were the HAD mutants. We discuss the possibility that the sialic acid binding activity helps TGEV to resist detergent-like substances encountered during the gastrointestinal passage and thus facilitates the infection of the intestinal epithelium. An alternative function of the sialic acid binding activity - accessory binding to intestinal tissues - is also discussed.  (+info)

Downstream ribosomal entry for translation of coronavirus TGEV gene 3b. (6/203)

Gene 3b (ORF 3b) in porcine transmissible gastroenteritis coronavirus (TGEV) encodes a putative nonstructural polypeptide of 27.7 kDa with unknown function that during translation in vitro is capable of becoming a glycosylated integral membrane protein of 31 kDa. In the virulent Miller strain of TGEV, ORF 3b is 5'-terminal on mRNA 3-1 and is presumably translated following 5' cap-dependent ribosomal entry. For three other strains of TGEV, the virulent British FS772/70 and Taiwanese TFI and avirulent Purdue-116, mRNA species 3-1 is not made and ORF 3b is present as a non-overlapping second ORF on mRNA 3. ORF 3b begins at base 432 on mRNA 3 in Purdue strain. In vitro expression of ORF 3b from Purdue mRNA 3-like transcripts did not fully conform to a predicted leaky scanning pattern, suggesting ribosomes might also be entering internally. With mRNA 3-like transcripts modified to carry large ORFs upstream of ORF 3a, it was demonstrated that ribosomes can reach ORF 3b by entering at a distant downstream site in a manner resembling ribosomal shunting. Deletion analysis failed to identify a postulated internal ribosomal entry structure (IRES) within ORF 3a. The results indicate that an internal entry mechanism, possibly in conjunction with leaky scanning, is used for the expression of ORF 3b from TGEV mRNA 3. One possible consequence of this feature is that ORF 3b might also be expressed from mRNAs 1 and 2.  (+info)

The viral nucleocapsid protein of transmissible gastroenteritis coronavirus (TGEV) is cleaved by caspase-6 and -7 during TGEV-induced apoptosis. (7/203)

The transmissible gastroenteritis coronavirus (TGEV), like many other viruses, exerts much of its cytopathic effect through the induction of apoptosis of its host cell. Apoptosis is coordinated by a family of cysteine proteases, called caspases, that are activated during apoptosis and participate in dismantling the cell by cleaving key structural and regulatory proteins. We have explored the caspase activation events that are initiated upon infection of the human rectal tumor cell line HRT18 with TGEV. We show that TGEV infection results in the activation of caspase-3, -6, -7, -8, and -9 and cleavage of the caspase substrates eIF4GI, gelsolin, and alpha-fodrin. Surprisingly, the TGEV nucleoprotein (N) underwent proteolysis in parallel with the activation of caspases within the host cell. Cleavage of the N protein was inhibited by cell-permeative caspase inhibitors, suggesting that this viral structural protein is a target for host cell caspases. We show that the TGEV nucleoprotein is a substrate for both caspase-6 and -7, and using site-directed mutagenesis, we have mapped the cleavage site to VVPD(359) downward arrow. These data demonstrate that viral proteins can be targeted for destruction by the host cell death machinery.  (+info)

Engineering the largest RNA virus genome as an infectious bacterial artificial chromosome. (8/203)

The construction of cDNA clones encoding large-size RNA molecules of biological interest, like coronavirus genomes, which are among the largest mature RNA molecules known to biology, has been hampered by the instability of those cDNAs in bacteria. Herein, we show that the application of two strategies, cloning of the cDNAs into a bacterial artificial chromosome and nuclear expression of RNAs that are typically produced within the cytoplasm, is useful for the engineering of large RNA molecules. A cDNA encoding an infectious coronavirus RNA genome has been cloned as a bacterial artificial chromosome. The rescued coronavirus conserved all of the genetic markers introduced throughout the sequence and showed a standard mRNA pattern and the antigenic characteristics expected for the synthetic virus. The cDNA was transcribed within the nucleus, and the RNA translocated to the cytoplasm. Interestingly, the recovered virus had essentially the same sequence as the original one, and no splicing was observed. The cDNA was derived from an attenuated isolate that replicates exclusively in the respiratory tract of swine. During the engineering of the infectious cDNA, the spike gene of the virus was replaced by the spike gene of an enteric isolate. The synthetic virus replicated abundantly in the enteric tract and was fully virulent, demonstrating that the tropism and virulence of the recovered coronavirus can be modified. This demonstration opens up the possibility of employing this infectious cDNA as a vector for vaccine development in human, porcine, canine, and feline species susceptible to group 1 coronaviruses.  (+info)

Emerging coronaviruses represent serious threats to human and animal health worldwide, and no approved therapeutics are currently available. Here, we used Transmissible gastroenteritis virus (TGEV) as the alpha-coronavirus model, and investigated the antiviral properties of curcumin against TGEV. Our results demonstrated that curcumin strongly inhibited TGEV proliferation and viral protein expression in a dose-dependent manner. We also observed that curcumin exhibited direct virucidal abilities in a dose-, temperature- and time-dependent manner. Furthermore, time-of-addition assays showed that curcumin mainly acted in the early phase of TGEV replication. Notably, in an adsorption assay, curcumin at 40 µM resulted in a reduction in viral titres of 3.55 log TCID50 ml-1, indicating that curcumin possesses excellent inhibitory effects on the adsorption of TGEV. Collectively, we demonstrate for the first time that curcumin has virucidal activity and virtual inhibition against TGEV, suggesting that curcumin

AU - Halbur, Patrick G.. PY - 1997/7/4. Y1 - 1997/7/4. N2 - Coronaviruses have been commonly associated with enteric and respiratory diseases. Two of the swine coronaviruses, namely transmissible gastroenteritis virus (TGEV) and porcine respiratory coronavirus (PRCV) have been extensively studied. TGEV replicates in both the enteric and respiratory tracts and causes enteric disease, whereas, PRCV replicates in the respiratory tract with limited to no replication in the enteric tract. We have isolated PRCV from swine herds with respiratory disease and have reproduced moderate pneumonia in gnotobiotic and conventionally reared pigs with two of the PRCV isolates. We have also identified two PRCV isolates with low virulence. One consistent difference that we have observed between PRCV isolates of different ...

Gastroenteritis virus - But what exactly is gastroenteritis? What are the causes, symptoms and treatment of this disease and how can you avoid it?
The recent emergence of a number of new viral diseases as well as the re-emergence of tuberculosis (TB), indicate an urgent need for new drugs against viral and bacterial infections.. Coronavirus nsp1 has been shown to induce suppression of host gene expression and interfere with host immune response. However, the mechanism behind this is currently unknown. Here we present the first nsp1 structure from an alphacoronavirus, Transmissible gastroenteritis virus (TGEV) nsp1. Contrary to previous speculation, the TGEV nsp1 structure clearly shows that alpha- and betacoronavirus nsp1s have a common evolutionary origin. However, differences in conservation, shape and surface electrostatics indicate that the mechanism for nsp1-induced suppression of host mRNA translation is likely to be different in the alpha- and betacoronavirus genera.. The Modoc virus is a neuroinvasive rodent virus with similar pathology as flavivirus encephalitis in humans. The flaviviral methyltransferase catalyses the two ...
Preliminary results from studies on immunity, directed by the National Pork Board, confirm immunity does appear not to be very long lived, said Lisa Becton, director of swine health information for the board. The board has collected more than $2 million for research on PEDv.. …. Veterinarians and others have been unable to predict the duration of immunity to PEDv in hogs following exposure, in part because the disease had never been in the United States before last year.. Ackerman had thought hogs would have a natural immunity to PEDv for three years after being infected because that is the case for a similar disease called Transmissible Gastroenteritis. Just because a farm broke with PEDv last year doesnt mean that they are protected from re-breaking with it this year, he said in a telephone interview.. Ackerman said he did not know why the female pigs, or sows, on the Indiana farm were re-infected after being exposed to the virus during the original outbreak last year. At the time, they ...

Michaela P. Trudeau, Harsha Verma, Pedro E. Urriola, Fernando Sampedro, Gerald C. Shurson, and Sagar M. Goyal The pork industry has recently experienced the devastating effects of swine corona viruses. The three known porcine corona viruses are transmissible gastroenteritis virus (TGEV), porcine delta corona virus (PDCoV), and porcine epidemic diarrhea virus (PEDV). Each of these viruses causes severe diarrhea in young pigs and increased mortality, with subsequent reductions in growth performance and increased cost to producers. These viruses are excreted through feces and can be spread by contaminated equipment, personnel, and other fomites.. After the 2013 outbreaks of PEDV in the United States, some evidence suggested that PEDV can be transmitted via contaminated feed and feed ingredients. In order to understand the role of virus-contaminated feed on its transmission, it is necessary to determine the risk of virus survival in various commonly used feed ingredients in swine diets. Our research ...
BACKGROUND: Pathogen contamination, causing transfusion-transmitted diseases, is an ongoing concern in transfusion of cellular blood products. In this explorative study, the pathogen-inactivating capacity of UVC irradiation in platelet (PLT) concentrates was investigated. The dose dependencies of inactivation of several viruses and bacteria were compared with the effect on PLT quality.. STUDY DESIGN AND METHODS: The potential of UVC irradiation was studied with a range of lipid-enveloped (LE) and non-lipid-enveloped viruses (NLE) and bacteria. LE viruses were bovine viral diarrhea virus (BVDV), human immunodeficiency virus (HIV), pseudorabies virus (PRV), transmissible gastroenteritis virus (TGEV), and vesicular stomatitis virus (VSV). NLE viruses were canine parvovirus (CPV) and simian virus 40 (SV40). Bacteria were Staphylococcus epidermidis, Staphylococcus aureus, Escherichia coli, and Bacillus cereus. After spiking and irradiation, samples were tested for residual infectivity and reduction ...
Porcine deltacoronavirus (PDCoV) is a newly detected porcine coronavirus causing serious vomiting and diarrhea in piglets, especially newborn piglets. There has been an outbreak of PDCoV in worldwide since 2014, causing significant economic losses in the pig industry. The interferon (IFN)-mediated antiviral response is an important component of virus-host interactions and plays an essential role in inhibiting virus infection. However, the mechanism of PDCoV escaping the porcine immune surveillance is unclear. In the present study, we demonstrated that the PDCoV nucleocapsid (N) protein antagonizes porcine IFN-β production after vesicular stomatitis virus (VSV) infection or poly(I:C) stimulation. PDCoV N protein also suppressed the activation of porcine IFN-β promoter when it was stimulated by porcine RLR signaling molecules. PDCoV N protein targeted porcine retinoic acid-inducible gene I (pRIG-I) and porcine TNF receptor associated factor 3 (pTRAF3) by directly interacting with them. The N-terminal
