Biologicals 2024; 86:101763. [PMID: 38641502 DOI: 10.1016/j.biologicals.2024.101763] [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: 05/26/2023] [Revised: 03/04/2024] [Accepted: 03/13/2024] [Indexed: 04/21/2024] Open
Abstract
This study aimed to investigate the prevalence of viral agents causing reproductive failure in pigs in Korea. In addition, two types of multiplex real-time PCR (mqPCR) were developed for the simultaneous detection of Aujeszky's disease virus (ADV) and porcine parvovirus (PPV) in mqPCR and encephalomyocarditis virus (EMCV) and Japanese encephalitis virus (JEV) in reverse transcription mqPCR (mRT-qPCR). A total of 150 aborted fetus samples collected from 2020 to 2022 were analyzed. Porcine reproductive and respiratory syndrome virus was the most prevalent (49/150 32.7%), followed by porcine circovirus type 2 (31/150, 20.7%), and PPV1 (7/150, 4.7%), whereas ADV, EMCV, and JEV were not detected. The newly developed mqPCR and mRT-qPCR could simultaneously detect and differentiate with high sensitivities and specificities. When applied to aborted fetuses, the newly developed mqPCR for PPV was 33.3% more sensitivities than the previously established diagnostic method. Amino acid analysis of the VP2 sequences of PPV isolates revealed considerable similarity to the highly pathogenic Kresse strain. This study successfully evaluated the prevalence of viral agents causing reproductive failure among swine in Korea, the developed mqPCR and mRT-qPCR methods could be utilized as effective and accurate diagnostic methods for the epidemiological surveillance of ADV, PPV, EMCV, and JEV.

Rapid detection of porcine encephalomyocarditis virus (EMCV) by isothermal reverse transcription recombinase polymerase amplification assays. J Virol Methods 2022; 306:114544. [PMID: 35595156 DOI: 10.1016/j.jviromet.2022.114544] [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: 03/16/2022] [Revised: 05/11/2022] [Accepted: 05/12/2022] [Indexed: 11/20/2022]
Abstract
In this study, we combined reverse transcription recombinase polymerase amplification assay with the fluorescence detection platform (qRT-RPA) and lateral flow biosensor (LFB RT-RPA) to allow for rapid detection of porcine encephalomyocarditis virus (EMCV). Primers and probes were designed to target the highly conserved region of 3D gene of porcine EMCV. The optimal reaction condition of qRT-RPA and LFB RT-RPA was set as 42 °C for 20 min. The assays were highly specific to EMCV and no cross-reactions were observed with seven other porcine viruses. With a 10-fold serially diluted EMCV genomic RNA as template, the limit of detection was 1.0 × 102 and 1.0 × 101 copies for qRT-RPA assay and LFB RT-RPA assay, respectively. A total of 92 samples from different sources were examined using qRT-RPA, LFB RT-RPA and qRT-PCR. We found 100% diagnostic agreement between qRT-RPA (23/92) and qRT-PCR (23/92), and 97.83% diagnostic agreement between LFB RT-RPA (25/92) and qRT-PCR (23/92). There was no significant difference in performance between the RT-RPA assays developed in this study and a previously described qRT-PCR. However, RT-RPA assays were rapid and easy to perform while LFB RT-RPA exhibited higher sensitivity for EMCV than qRT-PCR. Therefore, the developed EMCV RT-RPA assays provide an attractive and promising tool for effective detection of EMCV in low-resource settings.

Abstract
Despite significant economic and public health implications, swine enteric viruses that do not manifest clinical symptoms are often overlooked, and data on their epidemiology and pathogenesis are still scarce. Here, an epidemiological study was carried out by using reverse transcription-polymerase chain reaction (RT-PCR) and sequence analysis in order to better understand the distribution and genetic diversity of porcine astrovirus (PAstV), porcine encephalomyocarditis virus (EMCV), porcine kobuvirus (PKV), and porcine sapovirus (PSaV) in healthy pigs reared under specific pathogen-free (SPF) or conventional farms. PKV was the most prevalent virus (51.1%, 247/483), followed by PAstV (35.4%, 171/483), then PSaV (18.4%, 89/483), and EMCV (8.7%, 42/483). Overall, at least one viral agent was detected in 300 out of 483 samples. Out of the 300 samples, 54.0% (162/300), 13.0% (39/300), or 1.0% (3/300) were found coinfected by two, three, or four viruses, respectively. To our knowledge, this is the first report of EMCV detection from porcine fecal samples in China. Phylogenetic analysis revealed genetically diverse strains of PAstV, PKV, and PSaV circulating in conventional and SPF farms. Detection of swine enteric viruses with a high coinfection rate in healthy pigs highlights the importance of continuous viral surveillance to minimize future economic and public health risks.

Abstract
Encephalomyocarditis virus (EMCV) infects a wide range of hosts and can cause encephalitis, myocarditis, reproductive disorders and diabetes mellitus in selected mammalian species. As for humans, EMCV infection seems to occur by the contact with animals and can cause febrile illnesses in some infected patients. Here we isolated EMCV strain ZM12/14 from a natal multimammate mouse (Mastomys natalensis: M. natalensis) in Zambia. Pairwise sequence similarity of the ZM12/14 P1 region consisting of antigenic capsid proteins showed the highest similarity of nucleotide (80.7 %) and amino acid (96.2%) sequence with EMCV serotype 1 (EMCV-1). Phylogenetic analysis revealed that ZM12/14 clustered into EMCV-1 at the P1 and P3 regions but segregated from known EMCV strains at the P2 region, suggesting a unique evolutionary history. Reverse transcription PCR (RT-PCR) screening and neutralizing antibody assays for EMCV were performed using collected tissues and serum from various rodents (n=179) captured in different areas in Zambia. We detected the EMCV genome in 19 M. natalensis (19/179=10.6 %) and neutralizing antibody for EMCV in 33 M. natalensis (33/179=18.4 %). However, we did not detect either the genome or neutralizing antibody in other rodent species. High neutralizing antibody litres (≧320) were observed in both RT-PCR-negative and -positive animals. Inoculation of ZM12/14 caused asymptomatic persistent infection in BALB/c mice with high antibody titres and high viral loads in some organs, consistent with the above epidemiological results. This study is the first report of the isolation of EMCV in Zambia, suggesting that M. natalensis may play a role as a natural reservoir of infection.

Abstract
Encephalomyocarditis virus (EMCV) causes encephalitis, myocarditis, neuropathy, reproductive disorders, and diabetes in animals. EMCV is known to induce cell autophagy; however, the molecular mechanisms underlying this remain unclear. Here, we show that the type III-transmembrane protein, transmembrane protein 39A (TMEM39A), plays a critical role in EMCV replication. We showed that EMCV GS01 strain infection upregulated TMEM39A expression. Importantly, EMCV induced autophagy in a range of host cells. The autophagy chemical inhibitor, 3-MA, inhibited EMCV replication and reduced TMEM39A expression. This is the first study demonstrating TMEM39A promoting the replication of EMCV via autophagy. Overall, we show that TMEM39A plays a positive regulatory role in EMCV proliferation and that TMEM39A expression is dependent on the autophagy pathway.

Abstract
BACKGROUD Encephalomyocarditis virus (EMCV) has been discovered on pig farms worldwide and can cause myocarditis in piglets and reproductive failure in sows. However, little is known about the host transcriptional responses to infection and host-pathogen interactions. METHODS In this study, transcription profiling was performed by Illumina RNA-Sequencing (RNA-seq) to identify EMCV induced differentially expressed genes in BHK-21 cells at serial time points (12, 24, and 30 h post infection (hpi)), using mock infected cells as control. RESULTS We identified 237, 241, and 207 differentially expressed genes (DEGs) respectively, majority of which were up-regulated. A large number of DEGs clustered into host defense, cellular signaling and metabolism categories. Moreover, short time series expression analysis revealed that 12 hpi was an important time point for expression change, indicating host virus resistance. CONCLUSIONS This RNA-seq analysis provides the first data for understanding the network of virus host interactions under EMCV infection in vitro, and for identifying host components which involved in the virus infection course.

Abstract
We successfully constructed a full-length cDNA infectious clone of the encephalomyocarditis virus (EMCV) HB10 strain and obtained a partially attenuated rEMCV-C9 virus with a shorter poly(C) tract. Our results showed that the length of the EMCV-HB10 poly(C) tract was related to the pathogenicity of the EMCV-HB10 strain in vivo. Using pEMCV-C9 as the backbone, we constructed the novel viral vector pC9-MCS-∆2A by inserting a cDNA fragment containing a 127 amino acid deletion in the 2A protein, a primary cleavage cassette, a FLAG tag and a multiple cloning site (MCS) at the junction of VP1 and ∆2A. Additionally, the enhanced green fluorescent protein (egfp) gene was cloned into the MCS of pC9-MCS-∆2A to test its capacity to express foreign proteins. Insertion of the egfp gene did not affect viral replication, and a decrease in EGFP expression was observed within five serial passages. Furthermore, we found that rC9-EGFP-∆2A was avirulent in vivo, induced neutralizing antibody production and conferred protective immune responses against lethal challenge with EMCV in mice. Taken together, our results demonstrated that we had constructed an attenuated live vector based on an EMCV-HB10 strain with two modified critical virulence factors (the poly(C) tract and 2A protein) that could be used as a candidate live vaccine and a potential live viral vector for foreign antigen delivery.

Abstract
Reproductive failure in sows is one of the most important factors affecting pig breeding. Many reproductive disorders are linked to both environmental factors and infectious agents. The goal of our study was to determine the presence of pathogens that are known to cause abortion, considering a set of conditioning factors, such as seasonality and pregnancy period. A large number of aborted fetuses (1,625 fetuses from 140 farms) from a high-density breeding area in northern Italy was analyzed for a period of 3 years. The pigs were diagnosed based on direct (culture, PCR) or indirect (enzyme-linked immunosorbent assay) evidence. An infectious etiologic agent was found in 323 of 549 cases of abortion (58.8%). These included viral agents (Porcine circovirus-2, 138/323; Porcine reproductive and respiratory syndrome virus, 108/323; porcine parvovirus, 20/323; pseudorabies virus, 6/323; and Encephalomyocarditis virus, 3/323) and bacteria (Escherichia coli, 64/323; Streptococcus sp., 63/323; Staphylococcus sp., 5/323; Pasteurella sp., 3/323; Shigella sp., 1/323; and Yersinia sp., 1/323). This study describes the prevalence of infectious agents involved in reproductive failure in a high-density swine population. The data can be useful to swine breeders, practitioners, and medical specialists in monitoring animal health and in supervising the breeding process.

Abstract
Encephalomyocarditis virus (EMCV) can infect many host species and cause acute myocarditis and respiratory failure in piglets, reproductive failure in pregnant sows. In this study, an EMCV strain, designated JZ1202, was isolated from semi-captive wild boars that presented with acute myocarditis and sudden death in central China. It was identified by hemagglutination inhibition (HI) assay, reverse transcription polymerase chain reaction (RT-PCR) and genome sequencing. The subsequent results showed that the virus could produce a specific cytopathic effect on BHK cells and could cause clinical symptoms and pathological changes in mice. Complete genome sequencing and multiple sequence alignment indicated that JZ1202 strain was 81.3%-99.9% identical with other isolates worldwide. Phylogenetic analysis of the whole genome, ORF, VP3/VP1 and 3D genes using neighbor-joining method revealed that JZ1202 isolate was grouped into lineage 1. The results of this study confirmed that an EMCV strain JZ 1202 isolated from wild boar in central China was fatal to mice and provided new epidemiologic data on EMCV in China.
