Yu Y, Yao Y, Song Y, Shan H, Han X. Establishment and application of multiplex PCR for rapid detection of three mink diarrhea-associated viruses. J Virol Methods 2024; 328:114958. [PMID: 38801834 DOI: 10.1016/j.jviromet.2024.114958] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Revised: 05/07/2024] [Accepted: 05/19/2024] [Indexed: 05/29/2024]
Abstract
In this report, a multiplex PCR method was developed for the detection of three diarrhea-associated viruses in mink, including circovirus (MCV), bocavirus (MBoV), and enteritis virus (MEV). Three compatible sets of primers specific for each virus were designed respectively based on their conserved sequences. After optimization of the crucial factors such as primer concentration and annealing temperature in single and multiple amplification, three specific fragments were simultaneously amplified with the highest sensitivity and specificity in one PCR reaction. The fragments amplified were 259 bp (MCV),455 bp (MBoV) and 671 bp (MEV). The sensibility of this one-step multiplex PCR is about 10 times lower than that of regular singleplex PCR. There were no cross-reactions with some relevant pathogens like mink coronavirus, canine distemper virus, and aleutian mink disease virus. In our study we analyzed viral DNA in mink fecal samples by multiplex PCR assay from China, which revealed the occurrence of MCV, MBoV, and MEV as 3.1 %, 5.7 %, and 9.8 %, respectively. The testing results of multiplex PCR agreed with the singleplex PCR results with a coincidence rate of 100 %. These results indicated that the method could provide technical support for rapid detection of the three diarrhea-associated viruses, and epidemiological investigation of mink viral diarrhea.

Abstract
Canine coronavirus (CCoV), a member of the genus Alphacoronavirus, is an enveloped, single-stranded positive-sense RNA virus that responsible for gastroenteritis in dogs. In this study, two CCoV isolates were successfully propagated from 53 CCoV-positive clinical specimens by serial passaging in A-72 cells. These two strains, CCoV JS1706 and CCoV JS1712, caused cytopathic effects in A-72 cells. The sizes of virus plaque formed by them differed in early passages. Electron microscopy revealed a large quantity of typical coronavirus particles with 80–120 nm in diameter in cell culture media and cytoplasm of infected cells, in which they appeared as inclusion bodies. RT-PCR analysis of S gene indicated that these two isolates were belonged to CCoV IIa subtype. Homology of RdRp, S, M and N proteins between the two strains were 100, 99.6, 99.2 and 100.0%, respectively, whereas they were 99.4–100%, 83.1–95.2%, 88.5–99.2% and 91.9–99.7% identity compared to CCoV II reference strains. Phylogenetic analysis of RdRp, S, M and N protein showed that they were closely related to CCoV II strains. These two subtype IIa isolates will be useful for evaluating the pathogenesis and evolution of CCoV and for developing diagnostic reagents and vaccines.

Nucleotide sequences of the infectious DNA clones of two mink enteritis virus isolates exhibit the diversity of the terminal palindromic sequences and predicted secondary structures. Virus Res 2021; 305:198574. [PMID: 34555438 DOI: 10.1016/j.virusres.2021.198574] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2021] [Revised: 08/18/2021] [Accepted: 09/14/2021] [Indexed: 10/20/2022]
Abstract
In this study, the infectious RF-DNA clones of two mink enteritis viruses, MEV-SD1 and MEV-SD7, were constructed, which generated progeny virions and seemed to contain an almost or completely full-length genome. The genomes of MEV-SD1 and MEV-SD7 were 5162 bp and 5113 bp in length, respectively. The genomic organizations of MEV-SD1 and MEV-SD7 were similar to that of the other carnivore parvoviruses. The 3'-UTR of the virion strand of MEV-SD1 and MEV-SD7 were 311 bp and 313 bp in length, respectively, containing a 208 bp palindromic sequence assuming Y-shaped configurations. Interestingly, the difference of the 3' palindromic sequences between MEV-SD1 and MEV-SD7 resulted in the orientation inversion of the hairpin ears. And the 5'-UTRs of MEV-SD1 and MEV-SD7 were 582 bp and 531 bp, respectively, containing a 198 bp palindromic sequence assuming U-shaped configurations, a triplet mismatch (5'-TAC-3') in the center of the duplex stem and a triplet mismatch (5'-AGA-3') forming a small asymmetric bubble. The findings demonstrated that the genomic termini of the carnivore parvoviruses showed the diversity in length, base composition, and predicted secondary structure.

Abstract
Mink enteritis virus (MEV) is a major pathogen inducing acute hemorrhagic enteritis in mink. This study aims to determine the pathogenicity of the isolated MEV strain (SMPV-11) compared with the attenuated MEV strain (MEV-F61) in the mink. The two MEV strains were inoculated in the two mink groups, respectively. Then the clinical symptom, hematological, serological, and histopathological change were evaluated. Our findings showed that there were differences in the clinical features and pathological changes of the SMPV-11 and MEV-F61 in the mink. It indicates that SMPV-11 is a virulent strain, and it can be the potential MEV vaccine strain in the mink.

Generation and immunogenicity of virus-like particles based on mink enteritis virus capsid protein VP2 expressed in Sf9 cells. Arch Virol 2020; 165:2065-2071.

Abstract
Mink enteritis virus (MEV) is a parvovirus that causes acute enteritis in mink. The capsid protein VP2 of MEV is a major immunogenicity that is important for disease prevention. In this study, this protein was expressed in Spodoptera frugiperda 9 cells using a recombinant baculovirus system and was observed to self-assemble into virus-like particles (VLPs) with a high hemagglutination (HA) titer (1:216). A single-dose injection of VLPs (HA titer, 1:256) resulted in complete protection of mink against virulent MEV challenge for at least 180 days. These data suggest that these MEV VLPs could be used as a vaccine for the prevention of viral enteritis in mink.

Naturally-occurring right terminal hairpin mutations in three genotypes of canine parvovirus (CPV-2a, CPV-2b and CPV-2c) have no effect on their growth characteristics. Virus Res 2018; 261:31-36. [PMID: 30557578 DOI: 10.1016/j.virusres.2018.12.007] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2018] [Revised: 12/11/2018] [Accepted: 12/13/2018] [Indexed: 11/20/2022]
Abstract
We have isolated 4 naturally-occurring strains of CPV in mainland China and have identified them as CPV-2, 2a, 2b and 2c genotypes according to their VP2 sequences which also revealed substitutions within their right terminal regions. To determine if these substitutions affected the growth characteristics of the 4 strains, we constructed plasmids based on their genomic sequences minus their right terminal sequences, with the latter replaced by a single right terminal region. Analysis of rescued recombinants showed that the substitutions within their natural right termini had no significant effect on their growth characteristics.

Abstract
Virulent mink enteritis parvovirus (MEV) strain MEV-LHV replicated to higher titers in feline F81 cells than attenuated strain MEV-L. Phylogenetic and sequence analyses of the VP2 gene of MEV-LHV, MEV-L and other strains in GenBank revealed two evolutionary branches separating virulent and attenuated strains. Three residues, 101, 232 and 411, differed between virulent and attenuated strains but were conserved within the two branches. Site-directed mutagenesis of the VP2 gene of infectious plasmids of attenuated strain MEV-L respectively replacing residues 101 Ile and 411 Ala with Thr and Glu of virulent strains (MEV-L I101T and MEV-L A411E) increased replication efficiency but still to lower levels than MEV-LHV. However, viruses with mutation of residue 232 (MEV-L I232V and MEV-L I101T/I232V/A411E) decreased viral transcription and replication levels. The three VP2 residues 101, 232 and 411, located on or near the capsid surface, played different roles in the infection processes of MEV.
