  • Safeguarding Animal Health NVSL Mission • To safeguard U.S. animal health and contribute to public health by ensuring that timely and accurate laboratory support* is provided by a nationwide animal health diagnostic system.  Reference and confirmatory laboratory for USDA FY 2011 (Oct 2010 – Sept 2011): 66,800 accessions and 533,400 tests approved. * Includes both domestic and foreign animal diseases
  • Safeguarding Animal Health NVSL Activities • Conduct diagnostic testing • Supply reference reagents to other laboratories  Exchange diagnostic reagents with other laboratories to standardize and harmonize testing • Provide training in diagnostic techniques  State, university, private and foreign government laboratory personnel  APHIS or other agency personnel • Conduct proficiency testing of other laboratories • Consult on agents/techniques • Conduct developmental projects to improve diagnostic techniques for diseases of significance • Participate in World Organization for Animal Health (OIE) Collaborating Centre for the Diagnosis of Animal Diseases and Vaccine Evaluation in the Americas – CVB, ISU • Serve as OIE reference laboratory  high pathogenicity avian influenza, anthrax, pseudorabies, bluetongue, contagious equine metritis, equine encephalomyelitis, equine infectious anemia, leptospirosis, Newcastle disease, swine influenza, vesicular stomatitis and West Nile encephalitis • Serve as FAO reference center for vesicular diseases, classical swine fever, African swine fever 4
  • Safeguarding Animal Health Diagnostic Virology Laboratory • Dr. Bev Schmitt, Director • Dr. Sabrina Swenson, BPA Section Head • Dr. Eileen Ostlund, EO Section Head • [Vacant], Avian Section Head 5
  • Safeguarding Animal Health Schmallenberg Virus Update • First identified in Europe in August, 2011 • Affects sheep, goats, cattle, possibly other ruminants. • Impact on wild ruminants unknown at this time. • Fever, anorexia, diarrhea, and decreased milk production seen in adult cattle • Clinical signs non-specific; fetal malformations in sheep, goats or cattle 6
  • Safeguarding Animal Health Schmallenberg Virus - Agent • Closely resembles viruses in the genus Orthobunyavirus. • Other closely related viruses are Shamonda, Aino and Akabane viruses. • Not considered a human disease risk by CDC at this time. • Vaccine development underway; not available at this time. 7
  • Safeguarding Animal Health Schmallenberg Virus – Vector Range • Most likely transmitted by biting midges, thus transmission occurs during seasons when insects are most active. Fetus affected when dam infected during early pregnancy. • Belgian study – identified positive pools of Culicoides obsoletus and C. dewulfi • C. dewulfi not recorded in North America • C. obsoletus occurs in most of the U.S. and southern Canada 8
  • Safeguarding Animal Health Schmallenberg Virus – U.S. Response • Has not been found in the U.S. at this time • APHIS has issued an import alert which requires specific collection conditions for semen, embryos and other genetic material from the EU. • Trade restrictions are in addition to those already in place for the EU because of BSE. • USDA developed general information sheets to share with stakeholders and general public. • www.aphis.usda.gov/publications/animal_health/ 2012/schmallenberg_virus.pdf 9
  • Safeguarding Animal Health Schmallenberg Virus – Laboratory Capacity • NVSL has obtained the virus, protocols and reagents for PCR testing from Germany. • Have ability to conduct diagnostic tests (PCR, VI and VN) for Schmallenberg at NVSL (Ames and Plum Island). • NVSL-Ames can accept samples to test for Schmallenberg; work with AVIC and State Veterinarian, call NVSL for information on sampling procedures 10
  • Safeguarding Animal Health Schmallenberg Virus – Sampling Criteria for Submission to NVSL • Submit cases in ruminants where more than one dam produces fetus or neonate displaying signs of arthrogryposis hydranencephaly syndrome: stillbirths, mummies, muscle atrophy, joint malformations, etc. • Differential diagnostic testing for other causes of reproductive problems should be handled by local diagnostic laboratory.  Ames will only test for Schmallenberg virus and Cache Valley Fever virus 11
  • Safeguarding Animal Health Schmallenberg Virus – Submitting Samples • Initially requesting samples associated with reproductive signs  Fetal tissues: brain, heart blood, serum  Dam: serum ONLY • Submit to NVSL-Ames on our 10-4 submission form; indicate “Schmallenberg virus” as exam requested • Contact the VS AVIC and State Animal Health Official when submitting • If case is a FAD suspect, handle as FAD investigation as per VS Memo 580.4 12

Smaller volume production of Tube, Plate, and Rivanol antigens. • Successful production of Dourine CF antigen, Glander’s CF antigen, Anaplasma CF antigen, and various control serum. Diagnostic Bacteriology Laboratory
  • Safeguarding Animal Health • TB Cervid Stat-Pak Project: 1654 serum samples from Elk, White-Tailed Deer, and Reindeer were tested on the Cervid Stat-Pak. The goal of this project is to develop sensitivity and specificity values so that this test could potentially be used as a screening test or official test instead of the skin test for bovine TB. This project is ongoing and will continue in FY2012. • Samples provided by NVSL Serum Bank : ~ 425 Cervid samples ~ 250 Bovine samples 3734 Cervid samples and 2891 Cattle samples in bank 20 Diagnostic Bacteriology Laboratory
  • Safeguarding Animal Health Pathobiology Laboratory • Dr. Art Davis, Director • Dr. Walter Hyde, CAS Section Head • Dr. Mark Hall, PPE Section Head 21
  • Safeguarding Animal Health Pathobiology Laboratory 22 • The Pathobiology group receives approximately 10,000 samples annually for histopathological examination in support of the USDA Bovine Tuberculosis eradication program. Of these samples approximately 85-90% are from slaughter surveillance stream. • Also a participant in the evaluation of Permethrin for use in dip vat solutions against cattle fever ticks. • Conducting ongoing evaluation of three IHC TSE testing platforms (Ventana, BioCare, Leica) for use in VS Programs.
  • Safeguarding Animal Health CWD Rectal Biopsy Study • Test sensitivity for the rectal biopsy samples was approximately 70% compared to the gold standard of CWD testing on brain and or lymph nodes samples • Test sensitivity was influenced by animal genotype and stage of disease  RB test sensitivity is highest in prion protein codon 96 GG deer, with lower RB test sensitivity in 96GS and 96SS deer  Deer later in the course of the disease (as defined by increasing amounts of prion protein in the brain) have the greatest likelihood of a positive RB test  Conversely, deer early in the course of the disease that lack prion in the brain or have low amounts of prion, more frequently have false negative RB results
