Abstract
Cholesterol-25-hydroxylase (CH25 H) is a reticulum-associated membrane protein induced by an important interferon-stimulating gene (ISG) and can significantly inhibit some virus replication. But the effect of CH25H on encephalomyocarditis virus (EMCV) is still not clear. In this study, we found that EMCV infection increases significantly the endogenous CH25H expression in BHK-21 and N2a cells. CH25H and cholesterol catalytic oxidation product 25-hydroxycholesterol (25HC) obviously inhibits EMCV infection by inhibiting the viral penetration. But the CH25H mutant lacking hydroxylase activity repairs the ability to inhibit the viral replication. Meanwhile, β-cyclodextrin crystalline as a cholesterol inhibitor significantly decreases the viral replication. In addition, CH25H can selectively interact and degrade the viral RNA-Dependent RNA Polymerase-3D protein by independent on the association of proteasome, lysosome and caspase manner. It provides new insights into the interplay mechanisms between CH25H and non-enveloped single-stranded positive RNA viruses.

Abstract
EMCV genome was widely found in fecal guanos in Taiwanese, Korean, and Japanese caves. Miniopterus fuliginosus is the main source of the fecal guano. It is possible that Miniopterus fuliginosus is one of the natural hosts of EMCV in East Asia.
Bats are reservoir hosts of many zoonotic viruses and identification of viruses that they carry is important. This study aimed to use high throughput screening to identify the viruses in fecal guano of Taiwanese insectivorous bats caves in order to obtain more information on bat-derived pathogenic viruses in East Asia. Guano samples were collected from two caves in Taiwan, pooled, and then subjected to Multiplex PCR-based next generation sequencing for viral identification. Subsequently, encephalomyocarditis virus (EMCV) sequence was detected and confirmed by reverse transcription PCR. EMCV is considered as rodent virus and thus, animal species identification through cytochrome oxidase I (COI) barcoding was further done to identify the viral source. Finally, determination of distribution and verification of the presence of EMCV in guano obtained from Japanese and South Korean caves was also done. We concluded that the guano collected was not contaminated with the excrement of rodents which were reported and presumed to live in Taiwan. Also, EMCV genome fragments were found in guanos of Japanese and South Korean caves. It is possible that the eastern bent-wing bat (Miniopterus fuliginosus) is one of the natural hosts of EMCV in East Asia.

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
Encephalomyocarditis virus (EMCV) is one of the major zoonosis pathogens and can cause acute myocarditis in young pigs or reproductive failure in sows. In this study, a TaqMan-based real-time reverse transcription polymerase chain reaction (RT-PCR) assay targeting 3D gene of EMCV was developed and their sensitivities and specificities were investigated. The results indicated that the standard curve had a wide dynamic range (10(1)-10(6) copies/μL) with a linear correlation (R(2)) of 0.996 between the cycle threshold (Ct) value and template concentration. The real-time RT-PCR assay is highly sensitive and able to detect 1.4×10(2) copies/μL of EMCV RNA, as no cross-reaction was observed with other viruses. These data suggested that the real-time RT-PCR assay developed in this study will be suitable for future surveillance and specific diagnosis of EMCV-infection.
