  1. Retrospective study of owners’ perception on home monitoring of blood glucose in diabetic dogs and cats

    Van de Maele, I.; Rogier, N.; Daminet, S.
    Home monitoring of blood glucose (HMBG) concentrations has been recommended in the monitoring of human diabetics for 3 decades. During the last number of years, it also gained popularity in long-term follow-up of diabetic cats and dogs. The aim of this retrospective study was to evaluate the practical feasibility of and identify the major problems encountered with HMBG in diabetic pets. A standard questionnaire was filled in by owners of 9 diabetic pets monitored with HMBG. The need for more than 1 puncture to obtain a blood drop, the creation of a sufficient blood drop, the need for assistance in...

  2. Jejunal hemorrhage syndrome in dairy and beef cattle: 11 cases (2001 to 2003)

    Abutarbush, Sameeh M.; Radostits, Otto M.
    The medical records of 11 cattle with jejunal hemorrhage syndrome were reviewed. Female and male, lactating and pregnant, dairy and beef cattle were affected. Decreased feed intake and milk production, reduced amounts of dark feces, and abdominal discomfort were common historical findings. Common clinical findings included depressed demeanor, a “ping” and fluid-splashing sounds over the right abdomen, melena, and distended loops of intestine on rectal palpation. Surgery was done on 7 cases, 10 cases were euthanized, and 1 died. Clostridium perfringens type A was isolated from the intestinal contents from 7 of 7 cases. At necropsy, the characteristic finding was...

  3. Fungal colonization and failure of a long-term gastrostomy tube in a cat

    Boutilier, Pam; Carr, Anthony
    Candida krusei was isolated from a gastrostomy tube that failed 175 d after placement in a 13-year-old cat. Fungal colonization of gastrostomy tubes is common in humans and a contributor to tube failure. Veterinarians should be aware of this phenomenon in patients that have long-term indwelling feeding tubes.

  4. Investigation of a syndrome of sudden death, splenomegaly, and small intestinal hemorrhage in farmed deer

    Embury-Hyatt, Carissa K.; Wobeser, Gary; Simko, Elemir; Woodbury, Murray R.
    A newly recognized syndrome, characterized by sudden death of farmed deer that are in good to excellent nutritional condition, with lesions of small intestinal mucosal hemorrhage and splenomegaly, is described. Other frequently observed lesions were small intestinal mucosal necrosis, abomasal hemorrhage, random hepatic necrosis, and multifocal hepatic congestion. Clostridium perfringens type A was isolated in high numbers from the intestines of many of the deer affected by the syndrome; however, the numbers were not significantly different from those of control deer. The syndrome did not appear to be related to dietary or any other specific management factors and a definitive...

  5. Patent ductus arteriosus in a 9-day-old Grant’s zebra

    Slater, Sarah
    A 9-day old Grant’s zebra with a 3-day history of lethargy, weight loss, inappetance, and diarrhea was treated with ampicillin, vitamin E and selenium, and tetanus antitoxin without effect in 24 h. On transfer to the local veterinary clinic, a grade IV/VI continuous heart murmur was detected and a patent ductus arteriosus found at necropsy.

  6. Diagnosis and surgical remroval of a granulosa-theca cell tumor in a mare

    Maurice, Kathy T.
    An 8-year-old mare showed stallion-like behavior and aggressiveness. A granulosa-theca cell tumor was tentatively diagnosed based on history, transrectal palpation, and ultrasonography, and surgically removed. Serological levels of testosterone and inhibin were elevated. Histopathological examination confirmed the diagnosis. The mare recovered and by day 45 could be turned out with other horses.

  7. Metastasis of gastric adenocarcinoma to the abdominal wall following placement of a gastrostomy tube in a dog

    Nielsen, Cheri; Anderson, Gregory M.
    Stoma site metastasis of gastric adenocarcinoma was documented 37 d after partial gastrectomy with gastrostomy tube placement, and 22 d after tube removal. The tube was placed through grossly normal tissue but histopathologic examination revealed neoplasia at the surgical margins and concurrent lymphatic metastasis. Stoma site metastases may be due to direct tumor seeding or hemolymphatic spread.

  8. A retrospective study of sporadic bovine abortions, stillbirths, and neonatal abnormalities in Atlantic Canada, from 1990 to 2001

    Khodakaram-Tafti, Azizollah; Ikede, Basil O.
    In a retrospective study on 265 cases of sporadic bovine abortions, stillbirths, and neonatal deaths in Atlantic Canada (1990 to 2001), an etiological diagnosis was made in 117 cases (44.2%). The cases were divided into 2 groups: 234 abortions, and 31 stillbirths and neonatal deaths. Identified causes of abortion were bacteria (24.4%), fungi (6.8%), viruses (6.0%), protozoa (Neospora spp.) (2.1%), congenital anomalies (0.4%), and miscellaneous conditions (1.3%). In addition, placentitis without demonstrable infectious agents was observed in 17 (7.3%). Of the 31 cases of stillbirth and neonatal death, identified causes were dystocia (22.5%), congenital anomalies (22.5%), meconium aspiration syndrome (16.1%),...

  9. Serum gastrin in canine chronic lymphocytic-plasmacytic enteritis

    García-Sancho, Mercedes; Rodríguez-Franco, Fernando; Sainz, Ángel; Rodríguez, Antonio; Silván, Gema; Illera, Juan Carlos
    This study evaluates serum gastrin concentrations in dogs with chronic lymphocytic-plasmacytic enteritis, as well as its possible relationship with the severity of lesions present in the stomach. To achieve this aim, 5 dogs without gastrointestinal disease and 15 dogs with chronic lymphocytic-plasmacytic enteritis were included. Serum gastrin concentrations were significantly increased in dogs with chronic lymphocytic-plasmacytic enteritis compared with those in dogs without gastrointestinal disease. Also, there was a positive correlation between the severity of the gastric lesion and the serum gastrin concentration. Our findings indicate the possibility that gastrin plays a role in the etiology of an accompanying chronic...

  10. Effects of hemolysis, lipemia, hyperbilirrubinemia, and anticoagulants in canine C-reactive protein, serum amyloid A, and ceruloplasmin assays

    Martínez-Subiela, Silvi; Cerón, Jose J.
    The objective of the present study was to determine the effects that hemolysis, lipemia, bilirubinemia, and anticoagulants might have on the most commonly used assays for C-reactive protein and serum amyloid A, and determination of ceruloplasmin values in dogs. Solutions of hemoglobin, lipid, and bilirubin were added to serum aliquots. Additionally, serum and plasma samples with different anticoagulants (heparin, EDTA, and citrate) were obtained from healthy dogs. Hemolysis, lipemia, and hyperbilirubinemia interfered significantly with the C-reactive protein and ceruloplasmin results, but not with those for the serum amyloid A assay. The use of anticoagulants produced significant changes in the results...

  11. Lymphoplasmacytic gingivitis in a cat

    Baird, Kristin
    A 12-year-old male neutered short haired cat was presented due to difficulty eating and pawing at the face. Examination revealed severe gingivitis and stomatitis throughout the oral cavity. Gingival biopsy provided a diagnosis of lymphoplasmacytic stomatitis. Extraction of all premolars and molars resulted in elimination of all clinical signs.

  12. Sudden death due to thoracic lymphoma in a standardbred racing horse

    Lawn, Kelly
    During training, a 6-year-old standardbred gelding collapsed, exhibiting severe epistaxis and agonal breathing and was euthanized. The horse had a recent history of poor performance, lethargy, and unilateral eyelid swelling with serous ocular discharge. Postmortem and histopathologic examination findings revealed thoracic lymphosarcoma and concurrent exercise-induced pulmonary hemorrhage.

  13. Endometrial polyps in 2 African pygmy hedgehogs

    Phillips, Irene D.; Taylor, Jacqueline J.; Allen, Andrew L.
    Reports of spontaneously occurring endometrial polyps in animals are rare and have only involved a few species. This report is intended to advise veterinarians that older African pygmy hedgehogs may develop endometrial polyps and that these lesions can be a cause of bloody vaginal discharge, sometimes interpreted as hematuria.

  14. Detection of clusters of Salmonella in animals in Ontario from 1991 to 2001

    Zhang, Xi; McEwen, Beverly; Mann, Elroy; Martin, Wayne
    The temporal patterns of Salmonella serovars isolated from animals in Ontario by 2 major laboratories between 1991 and 2001 were identified. Overall, the number of isolates remained relatively stable and the more frequent isolates were dominant, as in earlier surveys. However, the temporal patterns of specific isolates and the serovars isolated differed depending on the laboratory, species of animal, and reason for obtaining the culture (monitoring versus diagnostic sample).

  15. Bacteriological evaluation of commercial canine and feline raw diets

    Weese, J. Scott; Rousseau, Joyce; Arroyo, L.
    Twenty-five commercial raw diets for dogs and cats were evaluated bacteriologically. Coliforms were present in all diets, ranging from 3.5 × 103 to 9.4 × 106 CFU/g (mean 8.9 × 105; standard deviation 1.9 × 106). Escherichia coli was identified in 15/25 (64%) diets; however, E. coli O157 was not detected. Salmonella spp. were detected in 5/25 (20%) diets; 1 each of beef-, lamb-, quail-, chicken-, and ostrich-based diets. Sporeforming bacteria were identified from 4/25 (16%) samples on direct culture and 25/25 (100%) samples using enrichment culture. Clostridium perfringens was identified in 5/25 (20%) samples. A toxigenic strain of C....

  16. A cross-sectional study of the causes of morbidity and mortality in farmed white-tailed deer

    Haigh, Jerry; Berezowski, John; Woodbury, Murray R.
    Two questionnaires were designed and administered. The first was to a random sample of 340 farmers of white-tailed deer (Odocoileus virginianus) in Canada and the United States. The second was a 10-year retrospective survey of deer submissions to veterinary diagnostic pathology laboratories in Canada and the United States. One-year rates of mortality and common causes of morbidity and mortality for the deer are reported. The primary diagnosis for each record was used to classify diseases into categories, such as parasitic, infectious, toxicological, and neoplastic. Submissions were further classified according to the anatomical location, the pathological change, and the etiology associated...

  17. Rupture of the peroneus tertius tendon in 27 horses

    Koenig, Judith; Cruz, Antonio; Genovese, Ron; Fretz, Peter; Trostle, Steve
    The purpose of the study was to identify factors influencing the outcome and prognosis of rupture of the tendon of the peroneus tertius muscle in 27 horses. Information on history, physical examination findings, diagnosis, treatment, and final outcome was summarized from medical records. Long-term follow-up information on horses was obtained by telephone survey. A stepwise logistic regression model was used to analyze factors influencing the outcome. Rupture occurred in the midbody of the tendon in 11 horses, at the insertion site in 11 horses, and at the origin in 2 horses. Overall, 18/23 (78.3%) horses returned to their previous level...

  18. Immune-mediated thrombocytopenia in a 4-month-old German shepherd dog

    Middleton, Shawn M.
    A 4-month-old, intact female, German shepherd dog exhibited a painful abdomen and lethargy. Immune-mediated thrombocytopenia was diagnosed and initial remission attained using prednisone. Upon relapse, prednisone and vincristine together were unsuccessful in achieving remission. This case is unique due to the young age of the dog.

  19. Blind omphalitis and palatine abscess in a bull calf

    Dittenhoffer, Christian
    Neurological, respiratory, and gastrointestinal signs in a 2-month-old veal calf were suggestive of a possible herd problem. Autopsy revealed an umbilical abscess, an abscess on the soft palate, and mild chronic enteritis and pulmonary edema. Virologic and bacteriologic investigations did not provide a definitive diagnosis.

  20. Scrutiny of antimicrobial use in racing horses with allergic small airway inflammatory disease

    Weese, J. Scott; Sabino, Catherine
    Antimicrobials had been administered to 38/55 (69%) racing standardbred and Thoroughbred horses with poor performance, subsequently diagnosed with nonseptic inflammatory airway disease. Horses with cough were more commonly treated (P = 0.02). In almost all cases, no clinical signs suggested that bacterial infection was present. Inappropriate use of antimicrobials was common.
