Leptospirose em cão: relato de caso

Abstract

Leptospirosis is a zoonotic infectious disease that affects various animal species, including dogs. This study aims to report a case of leptospirosis in a 6-year-old mixed-breed female dog in Vila Velha, Espírito Santo, Brazil. Initially referred with suspicion of biliary calculus, the patient presented icteric mucous membranes, lethargy, and pain on palpation. Ultrasonographic examination revealed significant renal and hepatic alterations. During hospitalization, laboratory tests indicated regenerative normocytic normochromic anemia, leukocytosis with a left shift, significant elevation of hepatic enzymes (ALT, AST, ALP, and GGT), hyperbilirubinemia (mainly indirect), hypoproteinemia due to hypoalbuminemia, and reduced urea levels due to hepatic complications. The diagnosis was suggested based on clinical findings and confirmed by serology. Despite receiving clinical support and showing initial improvement, the patient unfortunately progressed to death, highlighting the importance of early diagnosis, laboratory monitoring, and vaccination as an essential preventive measure against leptospirosis.
