Sheep and Goat

Small Ruminant Abortion - Sample Collection Tips

Dr. Jeff Hayes, ADDL Pathology Section Head

It is good to remember that the differential diagnosis for abortions in sheep and goats includes many infectious diseases that may also cause human illness. Tests for brucellosis, campylobacteriosis, chlamydophilosis, coxiellosis, leptospirosis, listeriosis, salmonellosis and toxoplasmosis are included in the small ruminant serology and fetus abortion diagnostic panels available at the ADDL. A key point is to collect and submit chilled and formalin-fixed placenta tissue - including cotyledons - whenever possible.  Remember to educate clients regarding sanitation and hygiene when handling aborted fetuses and placental membranes and fluids, in order to protect their own health. A convenient table for a list of differential diagnoses, preferred specimens, and test methods is available for review and downloading at the ADDL website: Abortion Panels.  If you have any questions about sheep and goat abortion diagnostic testing, please contact one of the pathologists at 614-728-6220.


Melanie Prarat, ADDL Virology Section

The Ohio Veterinary Medical Association held an informational meeting on November10th at the ODA campus regarding the U.S. Food and Drug Administration's (FDA) Veterinary Feed Directive (VFD). The final provisions of the VFD go into effect January 1, 2017. Speakers included the FDA, State Veterinarian Dr. Tony Forshey, as well as food animal practitioners and pharmaceutical representatives. The ODA Divisions of Plant Health, Dairy, Meat Inspection and the ADDL participated in the meeting. Requirements for veterinarians, food animal producers, and feed distributors were discussed.The new directive requires VFD drugs to be used only under the professional supervision of a licensed veterinarian.  To find out more information about VFD drugs, visit the FDA's VFD Requirements for Veterinarians and VFD Producer Requirements websites.


CWD Training Events


During the month of November, Dr. Craig Sarver, ADDL Pathology Section, conducted two trainings for collection of cervid tissue samples for chronic wasting disease (CWD) testing by immunochemistry. The first training involved staff from hunting preserves, and the second training involved personnel from three government agencies, the ODNR Division of Wildlife, USDA APHIS Veterinary Services and ODA field staff. The latter event also covered review of sample collection of head lymph nodes for tuberculosis surveillance.
