Bovine coronavirus associated syndromes.

ABSTRACT: Bovine coronaviruses, like other animal coronaviruses, have a predilection for intestinal and respiratory tracts. The viruses responsible for enteric and respiratory symptoms are closely related antigenically and genetically. Only 4 bovine coronavirus isolates have been completely sequenced and thus, the information about the genetics of the virus is still limited. This article reviews the clinical syndromes associated with bovine coronavirus, including pneumonia in calves and adult cattle, calf diarrhea, and winter dysentery; diagnostic methods; prevention using vaccination; and treatment, with adjunctive immunotherapy.

Fatal Interstitial Pneumonia Associated with Bovine Coronavirus in Cows from Southern Italy.

Project description:An outbreak of winter dysentery, complicated by severe respiratory syndrome, occurred in January 2020 in a high production dairy cow herd located in a hilly area of the Calabria region. Of the 52 animals belonging to the farm, 5 (9.6%) died with severe respiratory distress, death occurring 3-4 days after the appearance of the respiratory signs (caught and gasping breath). Microbiological analysis revealed absence of pathogenic bacteria whilst Real-time PCR identified the presence of RNA from Bovine Coronavirus (BCoV) in several organs: lungs, small intestine (jejunum), mediastinal lymph nodes, liver and placenta. BCoV was therefore hypothesized to play a role in the lethal pulmonary infection. Like the other CoVs, BCoV is able to cause different syndromes. Its role in calf diarrhea and in mild respiratory disease is well known: we report instead the involvement of this virus in a severe and fatal respiratory disorder, with symptoms and disease evolution resembling those of Severe Acute Respiratory Syndromes (SARS).

The nucleocapsid protein gene of bovine coronavirus is bicistronic.

Project description:For animal RNA viruses that replicate through an RNA intermediate, reported examples of bicistronic mRNAs with overlapping open reading frames in which one cistron is contained entirely within another have been made only for those with negative-strand or double-stranded genomes. In this report, we demonstrate for the positive-strand bovine coronavirus that an overlapping open reading frame potentially encoding a 23-kDa protein (names the I [for internal open reading frame] protein) and lying entirely within the gene for the 49-kDa nucleocapsid phosphoprotein is expressed during virus replication from a single species of unedited mRNA. The I protein was specifically immunoprecipitated from virus-infected cells with an I-specific antipeptide serum and was shown to be membrane associated. Many features of I protein synthesis conform to the leaky ribosomal scanning model for regulation of translation. This, to our knowledge, is the first example of a bicistronic mRNA for a cytoplasmically replicating, positive-strand animal RNA virus in which one cistron entirely overlaps another.

Canine Respiratory Coronavirus, Bovine Coronavirus, and Human Coronavirus OC43: Receptors and Attachment Factors.

Project description:Despite high similarity of canine respiratory coronavirus (CRCoV), bovine coronavirus, (BCoV) and human coronavirus OC43 (HCoV-OC43), these viruses differ in species specificity. For years it was believed that they share receptor specificity, utilizing sialic acids for cell surface attachment, internalization, and entry. Interestingly, careful literature analysis shows that viruses indeed bind to the cell surface via sialic acids, but there is no solid data that these moieties mediate virus entry. In our study, using a number of techniques, we showed that all three viruses are indeed able to bind to sialic acids to a different extent, but these molecules render the cells permissive only for the clinical strain of HCoV-OC43, while for others they serve only as attachment receptors. CRCoV and BCoV appear to employ human leukocyte antigen class I (HLA-1) as the entry receptor. Furthermore, we identified heparan sulfate as an alternative attachment factor, but this may be related to the cell culture adaptation, as in ex vivo conditions, it does not seem to play a significant role. Summarizing, we delineated early events during CRCoV, BCoV, and HCoV-OC43 entry and systematically studied the attachment and entry receptor utilized by these viruses.

Structure and orientation of expressed bovine coronavirus hemagglutinin-esterase protein.

Project description:The sequence of the hemagglutinin-esterase (HE) gene for the Mebus strain of bovine coronavirus was obtained from cDNA clones, and its deduced product is a 47,700-kilodalton apoprotein of 424 amino acids. Expression of the HE protein in vitro in the presence of microsomes revealed N-terminal signal peptide cleavage and C-terminal anchorage but not disulfide-linked dimerization. Dimerization was observed only after expression in vivo, during which HE was also transported to the cell surface.

Phages bearing affinity peptides to severe acute respiratory syndromes-associated coronavirus differentiate this virus from other viruses.

Project description:BACKGROUND:Transmission of SARS-associated coronavirus (SARS-CoV) is now well controlled, nevertheless, it is important to develop effective methods to identify this virus from other pathogens. OBJECTIVES:The purpose of this study was to identify potential ligands and develop a novel diagnostic test to SARS-CoV using phage display technology. STUDY DESIGN:The SARS-CoV spike 1 (S1) protein containing the receptor binding region (RBD) was used as an immobilized target followed by incubation with a 12-mer phage display random peptide library. After four rounds of biopanning, 10 monoclonal phages with specific binding activity to the S1-RBD protein were obtained and subjected to binding and diagnostic assays. RESULTS:DNA sequencing showed that two phage displayed peptides HHKTWHPPVMHL (phage-H) and SQWHPRSASYPM (phage-S) that were specific ligands to the S1 protein. Moreover, the selected phage-H and phage-S were capable of differentiating SARS-CoV from other coronaviruses in indirect enzyme-linked immunosorbent assays. CONCLUSION:The peptides identified in this study are useful reagents for detection of SARS-CoV.

First detection of bovine coronavirus in Yak (Bos grunniens) and a bovine coronavirus genome with a recombinant HE gene.

Project description:The yak (Bosgrunniens) is a unique domestic bovine species that plays an indispensable role for herdsmen in the Qinghai-Tibet Plateau. Here, 336 diarrhoeic samples were collected from yaks on 29 farms in the Qinghai-Tibet Plateau from 2015 to 2017. Approximately 69.05 % (232/336) of the diarrhoeic samples were assessed as bovine coronavirus (BCoV)-positive by RT-PCR assay, and most of the detected strains showed a unique evolution based on 40 spike (S), nucleocapsid (N) and haemagglutinin-esterase (HE) gene fragments. Notably, the 12 complete S genes detected shared 1 identical amino acid mutation (E121V) in the S1 subunit compared with the other 150 complete S genes in the GenBank database. Furthermore, a BCoV strain (designated YAK/HY24/CH/2017) was isolated from one diarrhoeic sample (virus titre : 108.17TCID50 ml-1), and a phylogenetic analysis based on complete genome sequences revealed that strain YAK/HY24/CH/2017 has the closest genetic relationship with the BCoV prototype strain Mebus. Interestingly, 2 significant characteristics were observed in the genome of strain YAK/HY24/CH/2017 : (1) the strain had 26 unique amino acid variations in the S gene compared with the other 150 BCoV S genes in the GenBank database and (2) a recombination event was identified between the esterase and lectin domains of the HE gene. In conclusion, this study revealed the high prevalence of BCoV in yaks in the Qinghai-Tibet Plateau. To the best of our knowledge, this is the first description of the molecular prevalence of BCoV in yaks and of a BCoV genome with an HE gene recombination.

Genetic characterization of bovine coronavirus in Vietnam.

Project description:A maximum clade credibility tree constructed using the full-length spike (S) and hemagglutinin-esterase genes revealed that Vietnamese Bovine coronavirus (BCoV) strains belong to a single cluster (C1); therefore, they might share a common origin with Cuban and Chinese BCoV strains. The omega values of cluster 1 (C1) and cluster 2 (C2) were 0.15734 and 0.11613, respectively, and naive empirical bayes analysis identified two amino acid positions (179 and 501) in the S protein in C1 and three amino acid positions (113, 501, and 525) in that of C2 that underwent positive selection (p > 99%). The evolutionary rate of C1 was estimated to be 7.6206 × 10-4 substitutions/site/year, and the most recent common ancestor (tMRCA) of Vietnamese BCoVs was estimated to date back to 1962 (95% HPD 1950-1973). The effective population sizes of C1 and C2 underwent a rapid reduction after 2000 and 2004, respectively.

Identification of a bovine coronavirus packaging signal.

Project description:A region of the bovine coronavirus (BCV) genome that functions as a packaging signal has been cloned. The 291-nucleotide clone shares 72% homology with the region of mouse hepatitis coronavirus (MHV) gene 1b that contains the packaging signal. RNA transcripts were packaged into both BCV and MHV virions when the cloned region was appended to a noncoronavirus RNA. This is the first identification of a BCV packaging signal. The data demonstrate that the BCV genome contains a sequence that is conserved at both the sequence and functional levels, thus broadening our insight into coronavirus packaging.
