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.
