Ohio ADDL Assists CDC and FDA in Campylobacter Outbreak

Melanie Prarat, MS, ADDL Virology Section

As a member of FDA's Veterinary Laboratory Investigation and Response Network (Vet-LIRN), the ADDL provides laboratory capacity for outbreak investigations to test for zoonotic pathogens.  

In September, the Ohio Department of Health (ODH) and the Center for Disease Control and Prevention (CDC) requested the ADDL to assist in the investigation of a multistate outbreak of human Campylobacter infections linked to puppies sold through a national pet store chain.  To date, 39 human cases have been identified in 7 states, including 18 people from Ohio.  Pet food and fecal samples from several Ohio pet stores have been submitted by investigators to ADDL for culture and PCR testing.  Whole genome sequencing of Campylobacter isolates is being performed by the ADDL and shared with the affiliated federal and state agencies for epidemiology studies.  


Campylobacteriosis is an infectious disease caused by bacteria of the genus Campylobacter. Animals including dogs infected with bacteria may or may not show clinical signs. 

This investigation is ongoing. Updates will be provided as more information becomes available.     


EHD Update

Dr. Jeff Hayes, MS, DVM, ADDL Pathology Section

As of September 27, 2017, the number of counties with white-tailed deer diagnosed with epizootic hemorrhagic disease (EHD) virus infection has expanded from three to 11 and the number of counties with infected cattle has increased from 2 to 4 since last month. Eleven individual wild deer and captive deer from 2 farms have been diagnosed from Belmont, Columbiana, Cuyahoga, Gallia, Highland, Holmes, Jefferson, Lorain, Pickaway, Pike, and Ross counties.  Confirmed infected cattle have been from Carrol, Columbiana, Highland and Jefferson counties. 


As clinical signs of EHD infection in cattle (reviewed in the September ADDL newsletter) may mimic those of reportable diseases such as foot and mouth disease, vesicular stomatitis and bluetongue, veterinary practitioners are reminded that they are to report such cases in cattle to the State Veterinarian (614-728-6220) or the USDA APHIS Area Director (614-856-4735). People are encouraged to report sightings of sick and dead deer to their local Division of Wildlife office.


Seven Horses Confirmed with WNV Infections in Ohio

Dr. Jeff Hayes, MS, DVM, ADDL Pathology Section

Ohio now has seven horses confirmed with West Nile virus (WNV) infections in 2017 as determined by serologic testing at the National Veterinary Services Laboratories in Ames, Iowa.  None of the seven affected horses had been vaccinated against WNV.  Two horses died spontaneously, one had to be euthanized due to poor prognosis, and four horses have recovered from illness, although two have sequela such as neurologic deficits. The horses have been from five counties - Ashtabula, Holmes, Logan (2 horses), Tuscarwaras, and Wayne (2 horses).  Six horses have been Standardbreds aged 4 to 12 years old and one was a 6 year old Belgian mare.  


Onset of clinical signs was observed in these horses between August 24 and September 5. Clinical signs reported among the affected horses included weakness of front or rear or all four limbs, incoordination, wobbling of the head, hypersensitivity to sound, sight and touch, muscle fasciculations, lethargy, inability or refusal to eat or drink, variable fever up to 103 F and recumbency  with inability to rise.


State Veterinarian Dr. Tony Forshey said these cases should serve as a reminder to get animals vaccinated and that vaccines are a proven prevention tool against viruses like WNV and EEE. In addition to vaccinations, horse owners also should work to reduce the mosquito population and eliminate possible breeding areas. Recommendations include: removing stagnant water sources; keeping animals inside during the bugs' feeding times, which are typically early in the morning and evening; and using mosquito repellents.

Upcoming CWD Training

October 31 is the date of the next annual Chronic Wasting Disease (CWD) training session for veterinarians who want to participate in the captive white-tailed deer herd certification program. The training will include presentations on herd inventory and testing requirements, inspections, a review of key cervid diseases and training on chronic wasting disease sample collection. The training will be from 9 am to 3 pm. Included in the afternoon is a wet lab where class members have hands on training in sample collection of obex and retropharyngeal lymph node samples. Training is free and includes notes and a notebook. Lunch is on your own. If you are interested in attending this year’s training, contact Christi Clevenger at 614-728-6220.

USDA/NIFA Offers Veterinary Medical Loan Repayment Program

Anne Parkinson, ADDL Serology Section

The USDA’s National Institute of Food and Agriculture (NIFA) has announced a program aimed at assisting veterinarians in repaying loans associated with the pursuit of their veterinary medicine degrees.  This program, the Veterinary Medical Loan Repayment Program (VMLRP), is authorized by the National Veterinary Medical Services Act and helps qualified veterinarians offset a significant amount of their school loans in return for their service in identified high-priority veterinary shortage situations.  If a veterinarian elects to enter a loan repayment agreement with NIFA, they will agree to provide veterinary services in an area experiencing a shortage of veterinarians for a determined amount of time.  NIFA can repay up to $25,000 of student debt per year when a veterinarian commits to at least three years of service in a designated shortage area.  To learn more about this program and how to apply, please refer to the VMLRP page on the NIFA website for additional information.
