Construction and characterization of a full-length infectious clone (pMEV) of mink enteritis virus are described. Feline kidney cells (F81) were transfected with pMEV containing an engineered BamHI site that served as a genetic marker. The rescued virus was indistinguishable from its parental virus. The availability of a MEV infectious clone will facilitate(More)
A virus isolated from mink showing clinical signs of enteritis was identified as a high virulent mink enteritis parvovirus (MEV) based on its biological characteristics in vivo and in vitro. Mink, challenged with this strain named MEV-LHV, exhibited severe pathological lesions as compared to those challenged with attenuated strain MEV-L. MEV-LHV also showed(More)
BACKGROUND The goal of this study was to assess the association between endometrial thickness on the chorionic gonadotropin (hCG) day and in vitro fertilization and embryo transfer (IVF-ET) outcome in normal responders after GnRH antagonist administration. METHODS A retrospective cohort study was performed in normal responders with GnRH antagonist(More)
Recent reports have indicated that phosphorylation of capsid proteins plays an important role in virion assemblage. Autonomous parvoviruses are among the smallest known viruses with an ssDNA genome enclosed within an icosahedral capsid. Here, we demonstrate that a structural protein (VP2) of one member, mink enteritis virus (MEV), is phosphorylated at(More)
Canine parvovirus (CPV) is an important and highly prevalent pathogen of dogs that causes acute hemorrhagic enteritis disease. Here, we describe a rapid method for the construction and characterization of a full-length infectious clone (rCPV) of CPV. Feline kidney (F81) cells were transfected with rCPV incorporating an engineered EcoR I site that served as(More)
Mink enteritis virus (MEV) is one of the most important viral pathogens causing serious disease in mink. Type I interferon (IFN) plays a critical role in antiviral innate immunity and, for successful infection, many viruses have evolved evasive strategies against it. Here, we show that MEV infection does not evoke IFN or interferon-stimulated genes (ISGs)(More)
Pathogenic strains of Aleutian mink disease virus (AMDV) such as Utah-1 do not replicate in cell culture (e.g., Crandell Rees feline kidney cells) while the in vitro-adapted AMDV strain ADV-Gorham (ADV-G) is not pathogenic. Here, we constructed a full-length infectious clone (pADV-G). Alignment of the VP2 gene of ADV-G with that of other AMDV strains(More)
The genome of a highly pathogenic strain of Aleutian disease mink virus (AMDV-BJ) isolated from a domestic farm in North China has been determined and compared with other strains. Alignment analysis of the major structural protein VP2 revealed that AMDV-BJ is unique among 17 other AMDV strains. Compared with the nonpathogenic strain ADV-G, the 3′ end(More)
The avian influenza virus (AIV) causes frequent disease with high morbidity and mortality. RNA interference (RNAi) has been shown to provide an effective antiviral defense in animals, and several studies have focused on harnessing small interfering RNAs (siRNAs) to inhibit viral infections. In addition, single chain variable fragments (scFvs) contain the(More)
