RESUMEN
Antibodies against Leishmania spp. are detected in most dogs with clinical signs of leishmaniasis due to Leishmania infantum. Accurate, rapid in-clinic serological tests may permit immediate confirmation of the diagnosis and implementation of therapeutic measures. The aim of the current study was to evaluate the diagnostic accuracy of 2 commercial, rapid in-clinic serological tests for the detection of anti-Leishmania antibodies in sera of dogs, the Snap Canine Leishmania Antibody Test kit (IDEXX Laboratories Inc., Westbrook, Maine) and the ImmunoRun Antibody Detection kit (Biogal Galed Labs, Kibbutz Galed, Israel), using indirect fluorescent antibody test (IFAT) as the reference method. A total of 109 sera collected from 65 seropositive and 44 seronegative dogs were used. The sensitivities of the Snap and ImmunoRun kits were 89.23% (95% confidence interval: 79.05-95.54%) and 86.15% (95% confidence interval: 75.33-93.45%), respectively, and the specificity of both tests was 100%. A good agreement between each of the rapid in-clinic serological tests and IFAT and between the 2 rapid in-clinic serological tests was witnessed. Both rapid in-clinic serological tests showed an adequate diagnostic accuracy and can be used for the fast detection of antibodies against L. infantum in dogs.

An 11-year-old, male Old English sheepdog was admitted for weight loss and intermittent vomiting of 1 month's duration. A cranioventral abdominal mass, anemia, hypoproteinemia, and hypoalbuminemia were the prominent abnormal findings. Imaging studies identified a remarkably thickened gastric wall with multilobulated folds protruding into the gastric lumen. Gastrotomy revealed the presence of giant cerebriform rugal folds arising from the fundus and body of the stomach. Pronounced gastric glandular hyperplasia and lack of evidence of cellular atypia were suggestive of giant hypertrophic gastritis. The dog was treated with prednisolone, cimetidine, and hyoscine butylbromide, only to experience a short-term remission.
