Leptospirose canina

Abstract

Canine leptospirosis is considered the most prevalent zoonosis, affecting various animal species, including humans, and representing a significant cause of morbidity and mortality globally. This report describes the case of an eight-year-old female dog that presented with generalized jaundice, anorexia, muscular weakness, markedly dark urine and diarrhea. The clinical signs began four days prior, following possible contact with rodents during daily walks on the street. Hematological analysis revealed mild normocytic normochromic anemia, leukocytosis due to neutrophilia without a left shift, and elevated levels of urea, creatinine, alkaline phosphatase (ALP), alanine aminotransferase (ALT), total bilirubin and its fractions. The definitive diagnosis was established through the microscopic agglutination test (MAT), which yielded a reactive result for Leptospira interrogans, serovar Icterohaemorrhagiae at a titer of 1: 100.Treatment included antibiotic therapy with doxycycline, combined with supportive care aimed at preserving the function of affected organs.
