Abstract

Necropsy examination of a five-year-old female German shepherd dog revealed a pale greyish-white thrombotic mass adherent to the lateral wall of left atrium of heart. Liver was enlarged, mottled and showed multifocal pale foci. Both kidneys were small, pale with granular cortical surface. Cultural examination of heart blood swab revealed the presence of Staphylococcus aureus. Clinical laboratory examination revealed elevation of blood urea nitrogen (312 mg/dL) and creatinine (19.7 mg/dL). Microscopical examination showed thrombotic mass adhering to the endocardial surface, which contained blood cell debris and numerous coccoid bacterial clumps. Blood vessels adjacent to the thrombus in the myocardium revealed mineralisation of the tunica intima with perivascular lympho-plasmacytic infiltration. Thus, a case of left atrial vegetative endocarditis developed from S. aureus infection due to uraemic endocardial injury is reported.
