Plain-English summary
A group of 70 dogs from a veterinary hospital in Brazil was tested for a serious disease called canine visceral leishmaniasis (CVL), which can be hard to diagnose because many dogs show no symptoms. Researchers looked at urine samples and found that 9.3% of the dogs had the Leishmania parasite in their urine. Additionally, 61% of the dogs tested positive for the parasite in their bone marrow or lymph nodes. This study highlights the importance of urine tests in diagnosing CVL, especially in dogs that may not show obvious signs of illness.

Abstract
Canine visceral leishmaniasis (CVL) is difficult to diagnosis, mainly due to the presence of asymptomatic animals, the diversity of clinical symptoms and the difficulty in obtaining diagnostic evidence of high sensitivity and specificity. The purpose of this study was to diagnose CVL in urinary sediment of 70 dogs of different breeds, sexes and ages from the veterinary hospital of the Federal University of Piauí and Zoonosis Control Center of Teresina, Brazil. The serological tests were TR DPP® for CVL and enzyme-linked immunosorbent assay (ELISA) for CVL, parasitological exams of bone marrow and lymph nodes and urine sediment cultures. Leishmania was detected in the bone marrow and/or lymph node of 61.0% of the animals (43/70), and urine sediment culture was positive in 9.30% (4/43) of these animals. In the serological exams, 70.0% (49/70) were reactive using the DPP and 78.2% (55/70) were reactive using ELISA. The goal of this study was to diagnose the presence of L. (infantum) chagasi in a culture of urinary sediment.
