  • 9/22/2017: (VT) Hypocholesterolemia was confirmed with cholesterol analysis of a serum sample from a 3 month old, unthrifty Holstein calf with chronic diarrhea. This condition is a recently recognized congenital genetic disorder of Holsteins. In this case, the dam to this calf was a known carrier (heterozygote) but the bull was not thought to be a carrier.

  • 9/22/2017: (NY) West Nile Virus (WNV)
    Clinton county 19 yr. old horse. This horse was euthanized.
    Livingston county 13 yr. old horse. This horse was recovering at last update.
    St. Lawrence county 2yr. old horse. The current condition of this horse has not been provided.
    Genesee county 1yr. old horse. This horse was recumbent and was euthanized.
    Erie county 1.5 yr. old horse. This horse was recumbent with seizures and was euthanized.

  • 9/21/2017: (NY) Case 1: Feline Lungworm (Aelurostrongylus abstrusus) detected by parasitological examination of a fecal sample from the cat from Tompkins County. A Fecal Qualitative exam was performed, consisting of double centrifugation flotation in both sugar and zinc sulfate solutions. Concurrent heavy infections with Toxocara cati (cat roundworm) and Ancylostoma tubaeforme (cat hookworm) were detected. Interestingly, the cat was also infected with Eucoleus aerophilus (another lungworm), Toxoplasma gondii and Aonchotheca putorii.

  • 9/21/2017: (NY) Case 2: Eucoleus boehmi was diagnosed in a dog by parasitological fecal analysis. This parasite has predilection for nasal turbinates and sinuses of dogs and wild carnivores and could cause clinical signs of sneezing and mucopurulent nasal discharge.

  • 9/18/2017: (NJ) Hemophilia A (Factor VIII deficiency) was identified as the cause of non-traumatic hemorrhage in a 16-week old male Pitbull mix puppy from NJ. The puppy had a history of shifting leg lameness, and had subcutaneous and intramuscular hematomas at presentation. An in-house APTT and PT were normal, however testing at the Comparative Coagulation Lab revealed a specific prolongation of APTT and severe Factor VIII deficiency (FVIII =1% of normal) thereby confirming a diagnosis of hemophilia A.

  • 9/15/2017: (NY) Tompkins County: West Nile Virus was confirmed as the cause of neurologic illness in a horse based on elevated IgG and IgM antibodies detected in a serum sample collected acutely during the course of disease. This mare had marked twitching of the muzzle as well as the muscles of the neck and front legs. She was very reluctant to move and had not been vaccinated for West Nile Virus in the past several years. The horse is recovering well at this point.

  • 9/15/2017: (NY) Orleans County: West Nile Virus was confirmed as the cause of neurologic illness in a horse. Once again, this diagnosis was confirmed based on elevated IgG and IgM antibodies detected in an acute serum sample. This gelding presented with stiffness in the front limbs, quivering lips, twitching of the head and a mild fever. This horse had not been vaccinated for West Nile Virus. This horse is also reported to be recovering fully.

  • 9/14/2017: (MD) Leptospirosis confirmed by serum MAT as a cause of bovine abortions. The Leptospira Pomona titers ranged from 800 to greater than or equal to 12,800. This herd is currently completely unvaccinated.

  • 9/14/2017: (NY) Bovine Virus diarrhea (BVD) was identified in tissues from an aborted Holstein fetus submitted for a complete abortion work-up. Subsequently 8 persistently infected (BVD PI) animals have been found in this dairy herd, comprised of 1800 adult animals and 1800 young stock. Testing is ongoing.

  • 9/13/2017: (NY) Infectious bronchitis virus (IBV) and Mycoplasma co-infection was confirmed in 2 of the 10 chickens that died with respiratory signs from a flock of 30 birds. The diagnosis was confirmed based on compatible necropsy lesions, Mycoplamsa culture, and IBV PCR, as well as testing to rule out other pathogens.

  • 9/13/2017: (NY) Infectious laryngotracheitis (ILT – herpesvirus) associated with respiratory signs was confirmed by histopathology (intranuclear inclusions) following necropsy of a 3-month old chicken from a multi-age and multi-species flock of 50 that were all showing respiratory distress. Gross lesions of a caseous exudate blocking the proximal trachea was typical of ILT.

  • 9/11/2017: (NY) West Nile virus (WNV) infection was confirmed in a Red Tailed Hawk from Long Island New York. PCR testing along with compatible gross and histologic lesions in the heart confirmed the diagnosis.

  • 9/7/2017: (NY) Blackleg (Clostridium chauvoei infection) was confirmed by anaerobic culture, fluorescent antibody tests, and histologic lesions in multiple 3-4 mo. old Angus calves following necropsy exams on the farm of origin by the attending veterinarian and multiple necropsies also performed at the AHDC. Approximately 15 out of 40 suckling calves died over several days. Skeletal muscle lesions were minimal, but cardiac muscle was affected in all calves where it was examined.

  • 8/30/2017: (OH) – West Nile Virus infection associated with neurologic illness was confirmed in a horse from Ohio with elevated WNV IgM and IgG antibodies on the WNV IgM/IgG capture ELISA test using a serum sample collected from the acutely ill horse. We received an update that the horse has made a good recovery.

  • 8/30/2017: Brucella Fluorescence Polarization Assay (FPA) testing is now available at our AHDC laboratory for testing animals for export to Canada. Testing is available M-F with a 1-2 day report lag time for Negative results.

  • 8/28/2017: (ME) Porcine multisystemic wasting syndrome associated with porcine circovirus -2 (PCV-2) infection was diagnosed in piglet tissues submitted by a Maine veterinarian, based on histopathology and PCV-2 fluorescent antibody test results.

  • 8/28/2017: (NY) Monensin toxicosis has been presumptively diagnosed in dead heifers from a NY dairy farm based upon histopathological lesions in multiple animals, elevated cardiac troponin in an antemortem sample, and a lack of other findings to explain sudden deaths in animals without significant gross or histologic lesions. Rumen content and total mixed ration monensin quantitative analysis are consistent with elevated levels in the diet in some samples.

  • 8/21/2017: (NY) Potomac horse fever was presumptively diagnosed in a horse from Clinton County, NY based on positive serum titer (Potomac Horse Fever IFA) of 6400 5-6 days after onset of febrile illness. Horse subsequently died due to devitalized and perforated bowel.

  • 8/21/2017: (VT) Leptospirosis diagnosed by PCR of urine specimen in 17 day old dead beef calf from Vermont. Calf was icteric and had dark red urine on necropsy. No lepto vaccines were used in the herd for several years.

  • 8/18/2017: (VT) Vermont goat herd. Clinical history: all goats are coughing. Muellerius capillaris lungworm larvae were identified in 2 out of 3 trans-tracheal wash samples. Inflammatory response was consistent with a lungworm infection in all 3 goats.
