Project description:We describe here transcripts induced after intraperitoneal injection of rainbow trout with 2 different viruses, both belonging to strain 23.75 of viral hemorrhagic septicemia virus (VHSV): a deleted Nv gene (dNV) virus and a wild type (wt) virus. Two days after infection, differentially expressed transcript levels from selected immune-related trout genes were studied in internal organs (spleen and head kidney). Fishes were divided in two groups (3 fishes per group). The first group was intraperitoneally injected with 100000 pfu per trout of dNV VHSV, while the second group was injected with 100000 pfu/trout of wt VHSV. All fishes were sacrificed two days post infection.

A pigtailed macaque model for Kyasanur Forest disease virus and Alkhurma hemorrhagic disease virus pathogenesis

Project description:Kyasanur Forest disease virus (KFDV) and the closely related Alkhurma hemorrhagic disease virus (AHFV) are emerging flaviviruses that cause severe viral hemorrhagic fevers in humans. Increasing geographical expansion and case numbers, particularly of KFDV in southwest India, class these viruses as a public health threat. Viral pathogenesis is not well understood and additional vaccines and antivirals are needed to effectively counter the impact of these viruses. However, current animal models for KFDV do not accurately reproduce viral tissue tropism or clinical outcomes observed in humans. Here, we show pigtailed macaques (Macaca nemestrina) infected with KFDV or AHFV develop viremia that peaks 2 to 4 days following inoculation. Over the course of infection, animals developed lymphocytopenia, thrombocytopenia, and elevated liver enzymes. Infected animals exhibited hallmark signs of human disease characterized by a flushed appearance, piloerection, dehydration, loss of appetite, weakness, and hemorrhagic signs such as epistaxis. Virus was commonly present in the gastrointestinal tract, consistent with human disease caused by KFDV and AHFV where gastrointestinal symptoms (hemorrhage, vomiting, diarrhea) are common. This work characterizes a nonhuman primate model for KFDV and AHFV that closely resembles human disease for further utilization in understanding host immunity and development of antiviral countermeasures.

Zebrafish early transcriptional response to viral haemorrhagic septicemia rhabdovirus (VHSV) challenge vs2

Project description:We describe here the transcripts induced after infection of zebrafish with viral haemorrhagic septicemia rhabdovirus (VHSV). Two days after infection, differentially expressed transcript levels from selected immune-related zebrafish genes were studied in both fins and internal organs (pooled spleen, head kidney and liver). VHSV-induced gene expression in zebrafish fins and organs was measured at 2 days after infection. Four independent experiments were performed for each treatment and their corresponding controls
