Abstract

Epidemiological, clinical and pathological aspects of canine leptospirosis diagnosed at the Animal Pathology Laboratory of Veterinary Hospital UFCG. Leptospirosis in dogs is a disease of great importance in clinical small animal, especially given the zoonotic potential of this disease. A retrospective study was performed in search of suspected cases of leptospirosis between period of January 2003 to August 2014 in LPA/HV/UFCG. A total of 1,142 dogs necropsied, 16 (1.4%) were diagnosed using epidemiological, clinical data and macro and microscopic lesions. Cases that had both hepatic and renal lesions consistent with injuries caused by leptospirosis were considered. The disease occurred mainly in adults, hybrid, from the urban area of Patos/PB, most often between the months of October and November. The clinical manifestations and lesions in organs were varied. The main clinical signs were described episodes of lethargy and lack of appetite, pale mucous membranes, dehydration, vomiting, bleeding, halitosis, among other less common signs. Had microscopically in liver necrosis and vacuolar degeneration of hepatocytes, hepatocyte dissociation of strands, lymphocytic inflammatory infiltrate, colestade, leucocitostase, congestion and hemorrhages. Had lymphocytic infiltrates in the kidney and degeneration and necrosis of epithelial cells of renal tubules inflammatory. Extra renal uremia secondary lesions were observed in 7 cases. It is concluded that leptospirosis is an endemic disease in the routine of LPA/HV/UFCG, being among the causes of death in dogs. The clinical diagnosis can be difficult considering the many presentations and the varied clinical course.
