  5. Outbreak investigation of porcine epidemic diarrhea in swine in Ontario

    Pasma, Tim; Furness, Mary Catherine; Alves, David; Aubry, Pascale
    Porcine epidemic diarrhea virus was first diagnosed in Ontario in January of 2014. An outbreak investigation was conducted and it was hypothesized that feed containing spray-dried porcine plasma contaminated with the virus was a risk factor in the introduction and spread of the disease in Ontario.

  6. Poorly differentiated cutaneous carcinoma of non-sebaceous origin in a 3-year-old Mongolian gerbil (Meriones unguiculatus)

    Fenton, Heather; Forzán, María J.; Desmarchelier, Marion; Woodland, Meghan; Sayi, Soraya; Gilroy, Cornelia V.
    A 3-year-old female gerbil developed a non-healing skin wound due to a malignant neoplasm. Histology, immunohistochemistry (cytokeratin 19 positive; vimentin, estrogen, and progesterone receptor negative), and electron microscopy (no desmosomes or melanosomes) revealed an undifferentiated carcinoma with pulmonary metastasis. Unlike in previous reports, it did not arise from the abdominal pad’s sebaceous gland.

  7. Aberrant heartworm migration to the abdominal aorta and systemic arteriolitis in a dog presenting with vomiting and hemorrhagic diarrhea

    Grimes, Janet A.; Scott, Katherine D.; Edwards, John F.
    A 2-year-old Dachshund was presented for vomiting and diarrhea. Abdominal ultrasound revealed Dirofilaria immitis in the abdominal aorta and an avascular segment of small intestine. The dog was euthanized. Necropsy revealed D. immitis in the abdominal aorta and widespread necrotizing arteriolitis. This is a unique presentation of aberrant migration of D. immitis.

  9. The use of dexmedetomidine continuous rate infusion for horses undergoing transvenous electrical cardioversion — A case series

    Marly-Voquer, Charlotte; Schwarzwald, Colin C.; Bettschart-Wolfensberger, Regula
    Five horses were presented for treatment of atrial fibrillation by transvenous electrical cardioversion (TVEC). A dexmedetomidine infusion was administered for sedation during positioning of the cardioversion catheters, and continued during general anesthesia. Shocks were applied until return to sinus rhythm. Dexmedetomidine infusion provided excellent conditions for TVEC catheter placement and procedure.

  10. Antimicrobial susceptibility of Staphylococcus pseudintermedius colonizing healthy dogs in Saskatoon, Canada

    Priyantha, Roshan; Gaunt, Mathew C.; Rubin, Joseph E.
    This study reports antimicrobial susceptibility of Staphylococcus pseudintermedius carried by healthy dogs in Saskatoon, and describes changes in antimicrobial resistance since a 2008 study. One hundred healthy dogs presenting to the wellness service at the Western College of Veterinary Medicine were screened for S. pseudintermedius by culturing rectal and pharyngeal swabs. Staphylococcus pseudintermedius was identified biochemically and antimicrobial minimum inhibitory concentrations were determined by broth microdilution. Methicillin resistance was confirmed by polymerase chain reaction (PCR) and sequencing of the mecA gene. Of 221 S. pseudintermedius isolates from 78 dogs, 7 were methicillin resistant. No resistance to the fluoroquinolones, nitrofurantoin, tigecycline,...

  11. Evaluation of surgical outcome, complications, and mortality in dogs undergoing preoperative computed tomography angiography for diagnosis of an extrahepatic portosystemic shunt: 124 cases (2005–2014)

    Brunson, Benjamin W.; Case, J. Brad; Ellison, Gary W.; Fox-Alvarez, W. Alexander; Kim, Stanley E.; Winter, Matthew; Garcia-Pereira, Fernando L.; Farina, Lisa L.
    This study evaluated the safety of preoperative computed tomography angiography (CTA) and its effect on surgical time and clinical outcomes in dogs that underwent surgical correction of a single congenital extrahepatic portosystemic shunt (CEPSS). Patient data were retrospectively collected from medical records and owner communications for 124 dogs with single CEPSS, undergoing preoperative CTA (n = 43) or not (n = 81) which were surgically treated from 2005 to 2014. The frequency of major postoperative complications was 4.7% and 9.9% for the CTA and no CTA groups, respectively (P = 0.49). Mean ± standard deviation (SD) surgical time for the...

  12. Characterizing 1341 cases of veterinary toxicoses confirmed in western Canada: A 16-year retrospective study

    Cowan, Vanessa; Blakley, Barry
    Veterinary toxicoses are frequently observed in western Canada. This study reports the frequency and characteristics of intoxications in animals reported between January 1, 1998 and December 31, 2013. Information was obtained from toxicological case records from the Prairie Diagnostic Services, Saskatoon, Saskatchewan. There were 1341 animal poisonings with 19 compounds over the investigational period. Lead poisoning was the most common toxicity (43.7%). Poisoning with acetylcholinesterase inhibitors and strychnine were also common events. Poisonings were most common in 2001, 2009, and 2012. Intoxications occurred most frequently during the months of May through July. Cattle were the most commonly poisoned species (n...

  13. Factors associated with development of Canine Infectious Respiratory Disease Complex (CIRDC) in dogs in 5 Canadian small animal clinics

    Joffe, Daniel J.; Lelewski, Roxana; Weese, J. Scott; Mcgill-Worsley, Jamie; Shankel, Catharine; Mendonca, Sonia; Sager, Tara; Smith, Michael; Poljak, Zvonimir
    This study investigated the association between presence of respiratory pathogens and development of Canine Infectious Respiratory Disease Complex (CIRDC) in dogs in 5 Canadian small animal clinics. In total, 86 dogs were tested using a commercial PCR respiratory panel; 64 dogs were considered as cases and 22 were control dogs matched by veterinary clinic. No control animals (0/22) were positive for canine parainfluenza virus (CPIV), whereas 27/64 (42%) CIRDC cases were positive. Furthermore, 81% of case dogs tested positive for Mycoplasma cynos, compared with 73% of control dogs. Canine respiratory corona virus (CRCoV) was detected in no control dogs compared...

  14. An observational study of mortality on bison farms in Saskatchewan with special emphasis on malignant catarrhal fever

    Epp, Tasha; Waldner, Cheryl; Woodbury, Murray
    In December 2011, the Malignant Catarrhal Fever (MCF) Task Force in Saskatchewan recommended that research be conducted on the relationship between the proximity of bison and sheep under typical commercial production settings and bison deaths due to MCF. The objective of this study was to evaluate all causes of death in bison herds and compare the incidence of MCF in herds at varying distances of exposure from sheep operations. Necropsies were completed on 76 of 133 bison reported to have died during the 18-month study period. A total of 7 MCF deaths was reported from 2 large herds within 1.0...

  19. Evaluation of plasma inflammatory cytokine concentrations in racing sled dogs

    von Pfeil, Dirsko J. F.; Cummings, Bethany P.; Loftus, John P.; Levine, Corri B.; Mann, Sabine; Downey, Robert L.; Griffitts, Caroline; Wakshlag, Joseph J.
    In human athletes significant changes in cytokine concentrations secondary to exercise have been observed. This prospective study evaluated the effect of a multi-day stage sled dog race on plasma concentrations of monocyte chemoattractant protein-1 (MCP-1), tumor necrosis factor-alpha (TNF-α), interleukin-2 (IL-2), interleukin-6 (IL-6), interleukin-8 (IL-8), and interleukin-10 (IL-10). Samples from 20 dogs were harvested prior to and on days 2 and 8 of an 8-day race. Exercise resulted in significantly decreased TNF-α and IL-8 as well as increases of MCP-1, IL-6, and IL-10 concentrations (P-value between 0.01 and < 0.0001 for all parameters). The proportion of values for IL-2 that...

  20. Sialolithiasis in horses: A retrospective study of 25 cases (2002–2013)

    Carlson, Nicholas; Eastman, Tim; Winfield, Laramie
    This study evaluated outcomes of surgical treatment of equine sialolithiasis, highlighting cases involving the proximal parotid salivary duct. Sialoliths in the proximal parotid duct were difficult to identify radiographically and more frequently associated with draining tracts and sialadenitis compared with sialoliths in the distal parotid duct. Ultrasonography confirmed the diagnosis of sialolithiasis in all cases in which there was no radiographic evidence of a sialolith. All cases of proximal parotid duct sialolithiasis required transcutaneous removal. A longer duration of illness was observed in cases of proximal parotid duct sialolithiasis compared with cases involving the distal parotid duct, and in cases...
