Animal Health Diagnostic Center - Emerging Issues

With recent events since Sept 11, concerns about deliberate exposure of people and animals to biological agents have been raised. This web page includes informational pieces to address some of the questions being asked by our clients concerning Anthrax and other animal diseases.

The potential for NYS animals to be exposed to agents such as anthrax has been addressed in the letter from Dr John Huntley, a PDF version is also available.

Note: Adobe Acrobat Reader, which can be downloaded for free from the Adobe Website, is needed to view and print PDF files.
 
 
Animal Health Advisory - Multi-drug Resistant Salmonella dublin in Cattle (15 Nov 06)

The Animal Health Diagnostic Center at Cornell University has isolated Salmonella dublin (Group D) from diagnostic samples submitted from multiple animals of 4 different cattle premises in either New York or Pennsylvania in the last 2 months. They have all shown the same antimicrobial sensitivity profile, being resistant to most antibiotics.

Salmonellosis is generally a disorder of the gastrointestinal tract. Salmonella dublin, however, is a cattle host-adapted strain that usually presents as a respiratory illness, primarily in young stock, although any age animal can be infected. Alternate clinical presentations may include septicemia, abortions in pregnant mature cows, and/or diarrhea, especially terminally. Some animals may remain lifetime carriers of this infection. Stress resulting from overcrowding, poor air quality, coinfections with other pathogens, poor hygiene, transportation, or dietary inadequacies can result in clinical signs in infected carrier animals. Recent introduction of Salmonella dublin into a population with no prior exposure, might, under the right conditions, result in an explosive outbreak.

In addition, all Salmonella spp. have the potential to infect people and can cause illness and death. To see the full text of this Salmonella dublin alert, please go to http://www.diaglab.vet.cornell.edu/pdf/Salmonelladublin.pdf or call 607-253-3900, and request a copy by mail or fax.

 
 
 
Anthrax Disease
Bacillus anthracis is NOT considered endemic in the State of New York.

While other regions of North America sporadically experience natural anthrax outbreaks, natural exposure to anthrax is uncommon in the Northeast. The last natural case in NY was identified near a wool mill in upstate NY in the mid 1980's.

BVD in Alpacas

Bovine Virus Diarrhea virus has been isolated from alpaca crias from sites around North America. Dr Dubovi, our virologist, has been working with alpaca farms on the East Coast and offers the following comments about testing:

The extent of the problem in alpacas is unknown. About a dozen PI crias have been identified. The Guelph group has a paper coming out in JVDI on the one that they had. I am not sure how the ACE (antigen capture ELISA) is performing. We have very weak reactions on serum -- 1 of 7 skin samples + on the one we did a necropsy on. However, the other one that died before it came here had an ACE skin test the equivalent to cattle. <more>

 
 
 
Canine Influenza Virus

The Animal Health Diagnostic Center at Cornell has conclusive evidence that canine influenza virus is now present in the New York City area. Reports have been received indicating that an unusual form of “kennel cough” has been seen in a number of veterinary practices. Animals recovering from this clinical presentation that have been tested are all serologically positive for canine influenza virus. Acute and convalescent sera from several dogs showed a positive response to canine influenza virus over the course of the illness. Tests of selected New York State dogs last year were all negative.<more>
