A 1-year and 8-month-old male, thoroughbred horse showed fever ($39.8^{\circ}C$), cardiac murmur, tachycardia up to 80 beats/min, anorexia, depression and lameness for about 2 months. The dead horse was referred to pathology laboratory at the College of Veterinary Medicine in Jeju National University. At necropsy, Severe protruding multiple rough cauliflower-like yellowish red nodules ranged $5{\sim}6{\times}2{\sim}3cm$ in size were attached on the mitral valve of the left heart. A yellowish red long stick-shaped thrombus $15{\times}3.5{\times}1.5cm$ in size was also present inside the right ventricle. Multifocal infarcts were scattered in the myocardium and renal cortex. Histopathologic examination revealed that morphologic diagnosis were vegetative endocarditis, thrombus in right ventricle, infarcts in myocardium and kidney, pulmonary congestion and edema, and splenic congestion. The isolated bacteria from vegetative lesions and thrombus were confirmed as Escherichia (E.) coli based on the bacterial culture and VITEK 2 system. Based on the gross and histopathologic features, and bacterial test, this case was diagnosed as vegetative endocarditis with thrombus formation associated by E. coli in a thoroughbred horse.

A 4-year-old Holstein cow with progressive atrophy and ataxia was submitted for diagnosis. The postmortem examination revealed multifocal yellowish nodules in the pulmonary parenchyma and vegetative masses in the mitral and tricuspid valve of the heart. Both kidneys were severely enlarged, with multiple yellow nodules on the parenchyma. Histopathologically, pulmonary abscesses, vegetative endocarditis, suppurative glomerulonephritis, and fibrino-purulent arthritis were observed. The tiny β-hemolytic bacterial colonies were isolated from the lesions and identified as Arcanobacterium haemolyticum by the VITEK 2 system (bioMérieux, USA). This is the first documented report of an A. haemolyticum infection in a Holstein cow in Korea.

A lactating Holstein cow which did not have had responded to drug therapy during 2 months was clinically examined. Right atrial vegetative endocarditis was determined dy ultrasonographic diagnosis, and later it was confirmed at necropsy. An early systolic

A 3-year-old intact female Maltese dog (2.5 kg of body weight) with the primary complaint of sudden onset of heart murmur, depression and anorexia was referred to the Veterinary Teaching Hospital of Kangwon National University. The dog was febrile with marked leukocytosis and left apical VI/VI holosystolic murmurs. The electrocardiogram implied the left ventricular enlargement. Diagnostic imaging studies revealed left atrial and ventricular dilation, severe vegetations on mitral valvular cusps with concurrent mitral regurgitation. Based on findings from clinical and diagnostic investigation, the case was diagnosed as vegetative mitral valvular regurgitation caused by infective endocarditis. The dog was successfully treated with broad spectrum antibiotics, diuretics, angiotensin converting enzyme inhibitor and antithrombotics.

A 12-year-old castrated male miniature Schnauzer had anorexia, vomiting, lethargy, and fever for four days. The dog had leukocytosis, thrombocytopenia, hypoglycemia, hypoalbuminemia, hyperbilirubinemia, increased hepatic enzymes on hematologic and biochemical examinations. On abdominal ultrasonographs, there was an enlarged gallbladder with hyperechoic irregular wall thickening. Echocardiography showed vegetative change and regurgitation of aortic and mitral valves. E.coli was identified through ultrasound guided percutaneous cholecystocentesis and bile culture. Bacterial cholecystitis and concurrent endocarditis were diagnosed. The dog was recovered from sepsis with antibacterial and aggressive supportive therapy.

Endocarditis associated with Escherichia coli was diagnosed in a 2-year-old male sea lion (Zalopus californianus). At necropsy, the heart had biventricular dilation with marked attenuation of the apex. Verrucous, grayish-red, vegetative lesions were present in both the aortic and left AV valves. Several discrete hyperemia-rimmed infarcts were noted in the kidneys. (omitted)
