Tree topologies indicated that the mosquito-borne alphaviruses could have arisen in either the Old or the New World, with at least two transoceanic introductions to account for their current distribution. The time frame for alphavirus diversifi- cation could not be estimated because maximum-likelihood analyses indicated that the nucleotide substitution rate varies considerably across sites within the genome. While most trees showed evolutionary relationships consistent with current antigenic complexes and species, several changes to the current classification are proposed. The recently identified fish alphaviruses salmon pancreas disease virus and sleeping disease virus appear to be variants or subtypes of a new alphavirus species. Southern elephant seal virus is also a new alphavirus distantly related to all of the others analyzed. -

Characterizing the Fecal Shedding of Swine Infected with Japanese Encephalitis Virus
Characterizing the fecal shedding of swine infected with Japanese encephalitis virus by Konner Cool B.S., Kansas State University, 2017 A REPORT submitted in partial fulfillment of the requirements for the degree MASTER OF SCIENCE Department of Diagnostic Medicine/Pathobiology College of Veterinary Medicine KANSAS STATE UNIVERSITY Manhattan, Kansas 2020 Approved by: Major Professor Dr. Dana Vanlandingham Copyright © Konner Cool 2020. Abstract Japanese encephalitis virus (JEV) is an enveloped, single-stranded, positive sense Flavivirus with five circulating genotypes (GI to GV). JEV has a well described enzootic cycle in endemic regions between swine and avian populations as amplification hosts and Culex species mosquitoes which act as the primary vector. Humans are incidental hosts with no known contributions to sustaining transmission cycles in nature. Vector-free routes of JEV transmission have been described through oronasal shedding of viruses among infected swine. The aim of this study was to characterize the fecal shedding of JEV from intradermally challenged swine. The objective of the study was to advance our understanding of how JEV transmission can be maintained in the absence of arthropod vectors. Our hypothesis is that JEV RNA will be detected in fecal swabs and resemble the shedding profile observed in swine oral fluids, peaking between days three and five. In this study fecal swabs were collected throughout a 28-day JEV challenge experiment in swine and samples were analyzed using reverse transcriptase-quantitative polymerase chain reaction (RT-qPCR). Quantification of viral loads in fecal shedding will provide a more complete understanding of the potential host-host transmission in susceptible swine populations. -

Dual Recognition of Herpes Simplex Viruses by TLR2 and TLR9 in Dendritic Cells
Dual recognition of herpes simplex viruses by TLR2 and TLR9 in dendritic cells Ayuko Sato†, Melissa M.

Flavell, Yale University School of Medicine, New Haven, CT, and approved September 27, 2006 (received for review June 18, 2006) Dendritic cells (DCs) express multiple Toll-like receptors (TLR) in and suppression of viral replication depended mostly on IRF7 and distinct cellular locations. Herpes simplex viruses (HSV) have been to a much lesser extent on MyD88 (6). reported to engage both the surface TLR2 and intracellular TLR9 in Although these three distinct pathways of herpesvirus recogni- conventional DCs.

The ability of kines in DCs remain unclear. Here, we demonstrate that a rare HSV-1 to trigger TLR2 has been shown to be responsible for the population of HSV, both in laboratory strains and in primary clinical exacerbation of neonatal herpes encephalitis (13), because neonatal isolates from humans, has the capacity to activate TLR2. This virus mice deficient in TLR2 secreted less IL-6 and had a higher rate of population is recognized through both TLR2 and TLR9 for the survival compared with WT mice upon lethal HSV-1 challenge. induction of IL-6 and IL-12 secretion from bone marrow-derived Further, the ability of HSV-1 and HSV-2 to activate TLR2 has been DCs. -

Varicella-Zoster Virus ORF57, Unlike Its Pseudorabies Virus UL3.5 Homolog, Is Dispensable for Viral Replication in Cell Culture

VY989349 Varicella-Zoster Virus ORF57, Unlike Its Pseudorabies Virus UL3.5 Homolog, Is Dispensable for Viral Replication in Cell Culture Edward Cox,1 Sanjay Reddy,1 Ilya Iofin, and Jeffrey I. Cohen2 Medical Virology Section, Laboratory of Clinical Investigation, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, Maryland 20892 Received May 27, 1998; returned to author for revision June 24, 1998; accepted July 23, 1998 Varicella zoster virus (VZV) encodes five genes that do not have homologs in herpes simplex virus. One of these genes, VZV ORF57, is predicted to encode a protein containing 71 amino acids. Antibody to ORF57 protein immunoprecipitated a 6-kDa protein in the cytosol of VZV-infected cells. Although the homolog of VZV ORF57 in pseudorabies virus, UL3.5, is critical for viral egress and growth in cell culture, VZV unable to express ORF57 replicated to titers similar to those seen with parental virus. Thus VZV ORF57 has a different role in viral replication than its pseudorabies virus homolog. INTRODUCTION itis virus UL3.5 to 220 amino acids for PRV UL3.5.
