Abstract
Gammaherpesviruses are an important class of oncogenic pathogens that are exquisitely evolved to their respective hosts. As such, the human gammaherpesviruses Epstein-Barr virus (EBV) and Kaposi sarcoma herpesvirus (KSHV) do not naturally infect nonhuman primates or rodents. There is a clear need to fully explore mechanisms of gammaherpesvirus pathogenesis, host control, and immune evasion in the host. A gammaherpesvirus pathogen isolated from murid rodents was first reported in 1980; 40 years later, murine gammaherpesvirus 68 (MHV68, MuHV-4, γHV68) infection of laboratory mice is a well-established pathogenesis system recognized for its utility in applying state-of-the-art approaches to investigate virus-host interactions ranging from the whole host to the individual cell. Here, we highlight recent advancements in our understanding of the processes by which MHV68 colonizes the host and drives disease. Lessons that inform KSHV and EBV pathogenesis and provide future avenues for novel interventions against infection and virus-associated cancers are emphasized.

Abstract
The laboratory mouse strain C57BL/6 is widely used as an animal model for various applications. It is becoming increasingly clear that the bacterial enteric community highly influences the phenotype. Eukaryotic viruses represent a sparsely investigated member of the enteric microbiome that might also affect the phenotype. We here investigated the presence of enteric eukaryotic DNA viruses (EDVs) in specific pathogen-free (SPF) C57BL/6N mice purchased from three vendors upon arrival and after being fed a low-fat diet (LFD) or high-fat diet (HFD). We detected genetic fragments of EDVs belonging to the viral families of Herpes-, Mimi-, Baculo- and Phycodnaviridae represented by two genera; Chlorovirus and Prasinovirus. The EDVs were detected in the mice upon arrival and persisted for 13 weeks. However, these signals of EDVs were only detected at notable levels in mice fed LFD from 2 out of 3 vendors, which suggested that the enteric composition of these EDVs were affected by both vendor (p < 0.003) and different dietary regimes (p < 0.013). This highlights the need of additional studies assessing the potential function of these EDVs that may influence the mouse phenotype and the reproducibility of animal studies using this C57BL/6N substrain.

Immune protection is dependent on the gut microbiome in a lethal mouse gammaherpesviral infection. Sci Rep 2020; 10:2371.

Abstract
Immunopathogenesis in systemic viral infections can induce a septic state with leaky capillary syndrome, disseminated coagulopathy, and high mortality with limited treatment options. Murine gammaherpesvirus-68 (MHV-68) intraperitoneal infection is a gammaherpesvirus model for producing severe vasculitis, colitis and lethal hemorrhagic pneumonia in interferon gamma receptor-deficient (IFNγR-/-) mice. In prior work, treatment with myxomavirus-derived Serp-1 or a derivative peptide S-7 (G305TTASSDTAITLIPR319) induced immune protection, reduced disease severity and improved survival after MHV-68 infection. Here, we investigate the gut bacterial microbiome in MHV-68 infection. Antibiotic suppression markedly accelerated MHV-68 pathology causing pulmonary consolidation and hemorrhage, increased mortality and specific modification of gut microbiota. Serp-1 and S-7 reduced pulmonary pathology and detectable MHV-68 with increased CD3 and CD8 cells. Treatment efficacy was lost after antibiotic treatments with associated specific changes in the gut bacterial microbiota. In summary, transkingdom host-virus-microbiome interactions in gammaherpesvirus infection influences gammaherpesviral infection severity and reduces immune modulating therapeutic efficacy.
