During this period, a total of 108,748 sera from wild boars were tested for the presence of PRV-specific antibodies using commercial enzyme-linked immunosorbent assays. The overall PRV seroprevalence was estimated at 12.09% for Germany. A significant increase in seroprevalence was observed in recent years indicating both a further spatial spread and strong disease dynamics. For spatiotemporal analysis, data from 1985 to 2009 from previous studies were incorporated. The analysis revealed that PRV infections in wild boar were endemic in all German federal states; the affected area covers at least 48.5% of the German territory. There were marked differences in seroprevalence at district levels as well as in the relative risk (RR) of infection of wild boar throughout Germany.

  • Phylogenetic and Recombination Analysis of the Herpesvirus Genus Varicellovirus Aaron W
    Kolb et al. BMC Genomics (2017) 18:887 DOI 10.1186/s12864-017-4283-4 RESEARCH ARTICLE Open Access Phylogenetic and recombination analysis of the herpesvirus genus varicellovirus Aaron W. Kolb1, Andrew C. Lewin2, Ralph Moeller Trane1, Gillian J. McLellan1,2,3 and Curtis R. Brandt1,3,4* Abstract Background: The varicelloviruses comprise a genus within the alphaherpesvirus subfamily, and infect both humans and other mammals. Recently, next-generation sequencing has been used to generate genomic sequences of several members of the Varicellovirus genus. Here, currently available varicellovirus genomic sequences were used for phylogenetic, recombination, and genetic distance analysis. Results: A phylogenetic network including genomic sequences of individual species, was generated and suggested a potential restriction between the ungulate and non-ungulate viruses. Intraspecies genetic distances were higher in the ungulate viruses (pseudorabies virus (SuHV-1) 1.65%, bovine herpes virus type 1 (BHV-1) 0.81%, equine herpes virus type 1 (EHV-1) 0.79%, equine herpes virus type 4 (EHV-4) 0.16%) than non-ungulate viruses (feline herpes virus type 1 (FHV-1) 0. 0089%, canine herpes virus type 1 (CHV-1) 0.005%, varicella-zoster virus (VZV) 0.136%). The G + C content of the ungulate viruses was also higher (SuHV-1 73.6%, BHV-1 72.6%, EHV-1 56.6%, EHV-4 50.5%) compared to the non-ungulate viruses (FHV-1 45.8%, CHV-1 31.6%, VZV 45.8%), which suggests a possible link between G + C content and intraspecies genetic diversity. Varicellovirus clade nomenclature is variable across different species, and we propose a standardization based on genomic genetic distance.

  • Aujeszky's Disease Control in Pigs? Cattle Exposed to Asymptomatically Infected Pigs
    Aujeszky’s Importance Aujeszky’s disease (pseudorabies) is a highly contagious, economically significant Disease disease of pigs. This viral infection tends to cause central nervous system (CNS) signs in young animals, respiratory illness in older pigs, and reproductive losses in sows. Pseudorabies, Mad Itch Mortality rates in very young piglets can be high, although older animals typically recover. Recovered swine can carry the virus latently, and may resume shedding it at a later time. Other species can be infected when they contact infected pigs or eat raw Last Updated: January 2017 porcine tissues, resulting in neurological signs that are usually fatal within a few days. Serious outbreaks were seen in cattle exposed to infected swine in the past, and thousands of farmed mink and foxes in China recently died after being fed contaminated pig liver. Why animals other than pigs do not typically survive this infection is not clear. Aujeszky’s disease can result in trade restrictions, as well as economic losses, in countries where it is endemic. It remains a significant problem among domesticated pigs in some parts of the world. Variants that recently caused outbreaks among vaccinated pigs in China may be a particular concern. Eradication programs have eliminated this disease from domesticated swine in many nations, including the U.S.. The disease has never been reported in Canada. However, viruses are often still maintained in feral pigs and wild boar, and could be reintroduced to domesticated pigs from this source. Viruses from wild suids have also sporadically caused Aujeszky’s disease in other animals, particularly hunting dogs.

  • The Expression and Serological Reactivity of Recombinant Canine Herpesvirus 1 Glycoprotein D
    ACTA VET. BRNO 2016, 85: 113-119; doi:10.2754/avb201685020113 The expression and serological reactivity of recombinant canine herpesvirus 1 glycoprotein D Markéta Vaňková1,2, Dobromila Molinková1,2, Vladimír Celer1,2 University of Veterinary and Pharmaceutical Sciences Brno, Faculty of Veterinary Medicine, 1Institute of Infectious Diseases and Microbiology, 2CEITEC – Central European Institute of Technology, Brno, Czech Republic Received January 16, 2016 Accepted May 2, 2016 Abstract The aim of this work was to express recombinant glycoprotein D of canine herpesvirus 1 in bacterial cells and to evaluate its diagnostic sensitivity and specificity when compared to traditional serological methods. The gene fragment coding glycoprotein D of canine herpesvirus 1 was amplified by polymerase chain reaction, cloned into plasmid vector and expressed in Escherichia coli cells. Recombinant protein was then purified and used as an antigen in immunoblot for a detection of canine herpesvirus 1 specific antibodies. Antibody testing was performed on the panel of 100 canine sera by immunoblot with recombinant glycoprotein D as antigen and compared with indirect immunofluorescence assay. Serum samples were collected from 83 dogs with no history of canine herpesvirus 1 or reproductive disorders, and from 17 dogs from breeding kennels with a history of canine herpesvirus 1 related reproductive disorders. Sensitivity of glycoprotein D based immunoblot was 89.2% and specificity was 93%. Kappa value was calculated to be 0.8 between immunoblot and indirect immunofluorescence assay. Antibodies against canine herpesvirus 1 infection were detected in 33% of samples by immunoblot assay. Our study confirms that recombinant glycoprotein D expressed in bacterial cells could be used as a suitable and sensitive antigen for immunological tests and that herpesvirus infection seems to be common among the canine population in the Czech Republic.

Current vaccines do not block interindividual spread from chicken-to- chicken, therefore, understanding MDV interindividual spread provides important information for the development of potential therapies to protect against MD, while also providing a natural host to study herpesvirus dissemination. It has long been thought that glycoprotein C (gC) of alphaherpesviruses evolved with their host based on their ability to bind and inhibit complement in a species-selective manner. Here, we tested the functional importance of gC during interindividual spread and host specificity using the natural model system of MDV in chickens through classical compensation experiments. By exchanging MDV gC with another chicken alphaherpesvirus (Gallid Citation: Vega-Rodriguez, W.; alphaherpesvirus 1 or infectious laryngotracheitis virus; ILTV) gC, we determined that ILTV gC Ponnuraj, N.; Garcia, M.; Jarosinski, could not compensate for MDV gC during interindividual spread.

  • Human Endophthalmitis Caused by Pseudorabies Virus Infection, China, 2017
    Article DOI: https://doi.org/10.3201/eid2406.171612 Human Endophthalmitis Caused By Pseudorabies Virus Infection, China, 2017 Technical Appendix Next Generation Sequencing The ophthalmologist collected 2 mL of the vitreous humor from the patient according to standard procedures, and we processed it accordingly. A 1.5ml microcentrifuge tube with 0.5mL sample and a 1g, 0.5mm glass bead were attached to a horizontal platform on a vortex mixer and agitated vigorously at 2,800–3,200 rpm for 30 minutes. A 0.3mL sample was separated into a new 1.5 mL microcentrifuge tube and DNA was extracted by using the TIANAmp Micro DNA Kit (Tiangen Biotech, Beijing, China) according to the manufacturer’s recommendation. We constructed DNA libraries through DNA-fragmentation, end-repair, add A-tailing, adaptor- ligation and PCR amplification. We used Agilent 2100 for quality control of the DNA libraries. Quality qualified libraries were sequenced by BGISEQ-100 platform. Polymerase Chain Reaction, Sanger Sequencing and Real-time PCR DNA was extracted by using the DNeasy Blood & Tissue Kit (QIAGEN, Hilden, Germany) for extraction according to the manufacturer’s recommendations and finally eluted in 100μL of buffer. Three pairs of specific primers were designed according to related articles (1,2,3) and the sequences of primers are summarized in Technical Appendix Table 1. All oligonucleotides were synthesized by BGI. All PCRs were completed by using the Takara RR902A Kit in a total reaction volume of 25 μL. For a single reaction, 8.5 μL RNase-free water, 12.5 μLPremix Taq and 2 μL primers were merged as a master mix.
