Group G streptococci which have been isolated from the oral flora of rats are also normal inhabitants of the human skin, oropharynx, gastrointestinal tract, and female genital tract. This group of streptococci can cause a wide variety of clinical diseases in humans, including septicemia, pharyngitis, endocarditis, pneumonia, and meningitis. Ten days after oral gavage with 7,12-dimethylbenz[a]anthracene, 12 of 22 two-month-old, female, outbred, viral-antibody-free rats presented with red ocular and nasal discharges and marked swelling of the cervical region. Various degrees of firm, nonpitting edema in the region of the cervical lymph nodes and salivary glands as well as pale mucous membranes and dehydration were observed. Pure cultures of beta-hemolytic streptococci were obtained from the cervical lymph nodes of three rats that were necropsied. A rapid latex test system identified the isolates to have group G-specific antigen. These streptococcal isolates fermented trehalose and lactose but not sorbitol and inulin and did not hydrolize sodium hippurate or bile esculin. A Voges-Proskauer test was negative for all six isolates. Serologic tests to detect the presence of immunoglobulin G antibody to rat viral pathogens and Mycoplasma pulmonis were negative. Histopathologic changes included acute necrotizing inflammation of the cervical lymph nodes with multiple large colonies of coccoid bacteria at the perimeter of the necrotiz zone. To our knowledge, this is the first report of naturally occurring disease attributed to group G streptococci in rats.

We reported a 29-year-old man with active endocarditis complicating aortic and mitral valve regurgitation. The echocardiogram showed a mycotic aneurysm at aortic valvular annulus and a aneurysm of mitral valve. Heart failure was progressive and caused anuria. Prior to emergent double valve replacement, 2,500 ml of water was removed. Then hemodynamics became stationary. Urination was good during and after operation. In this case, complicating acute renal failure, dehydration with extracorporeal ultrafiltration method was very effective for improvement of hemodynamics.

A 6-year-old male Doberman Pinscher developed multiple organ infarctions secondary to vegetative endocarditis. Clinical signs included fever, nystagmus, head-tilt, inappetence, dehydration, hematuria, and dysuria. The dog was azotemic and anemic and had a high WBC count and high liver enzyme activities. Disseminated intravascular coagulation was diagnosed on the basis of thrombocytopenia and prolonged activated clotting times. Vegetative mitral valvular lesions were evident on M-mode echocardiography. The dog underwent diuresis with physiologic saline solution and was treated parenterally with antibacterial and anticoagulant agents. Surgery was performed to remove an infarcted kidney and an infarcted spleen and to relieve urethral obstruction caused by a large blood clot. Gram-positive cocci were noticed in the biopsy specimens. Mortality associated with organ infarctions secondary to bacterial endocarditis is high, and combined medical and surgical therapy is rarely reported. This dog survived and was alive 38 months after surgery.

Pulmonary thromboembolism (PTE) is uncommonly diagnosed in the pediatric patient, and indeed often only discovered on autopsy. The incidence of pediatric PTE depends upon the associated underlying disease, diagnostic tests used, and index of suspicion. Multiple risk factors can be found including: peripartum asphyxia, dyspnea, haemoptysis, chest pain, dehydration, septicemia, central venous lines (CVLs), trauma, surgery, ongoing hemolysis, vascular lesions, malignancy, renal disease, foreign bodies or, uncommonly, intracranial venous sinus thrombosis, burns, or nonbacterial thrombotic endocarditis. Other types of embolism can occur uncommonly in childhood and need to be recognized, as the required treatment will vary. These include pulmonary cytolytic thrombi, foreign bodies, tumor and septic emboli, and post-traumatic fat emboli. No single noninvasive test for pulmonary embolism is both sensitive and specific. A combination of diagnostic procedures must be used to identify suspect or confirmed cases of PTE. This article reviews the risk factors, clinical presentation and treatment of pulmonary embolism in children. It also highlights the current diagnostic tools and protocols used to evaluate pulmonary embolism in pediatric patients.

A 6 yr old female spayed large Munsterlander was evaluated following a 3 wk history of lethargy, inappetence, intermittent fever, and a recent change to the timing of her previously diagnosed heart murmur. Physical examination revealed marked dehydration, lethargy, and a grade 5/6 to-and-fro heart murmur that was auscultated best at the right sternal border. The dog was febrile, and echocardiography revealed a large, mobile, vegetative lesion in the right ventricular outflow tract associated with a ventricular septal defect (VSD). Mild aortic insufficiency was present. Corynebacterium mustelae (C. mustelae) was isolated from a pooled blood culture. Treatment of infective endocarditis (IE) was initiated along with supportive care, and the patient was discharged 9 days later. The dog remained without clinical signs 132 days after discharge. VSD is rarely mentioned as a predisposing factor for development of IE in veterinary literature; however, this report highlights that dogs with a VSD may be at risk for IE. To the authors' knowledge, this is the first documented case of a canine infection with C. mustelae. Infection with C. mustelae in this case represents a novel agent for IE in the dog.

Bi-valvular pneumococcal endocarditis in Austrian syndrome, which includes a triad of pneumococcal endocarditis, pneumonia, and meningitis, is a rare but life-threatening disease. We present a case of a woman found to have Austrian syndrome who presented to the emergency department (ED) with dehydration and radiographical signs of lobar pneumonia and quickly deteriorated to fulminant cardiogenic shock in less than four hours. An early echocardiogram in the ED confirmed a diagnosis of bi-valvular endocarditis with severe aortic and mitral valve insufficiency and large vegetations on the valve leaflets requiring emergent surgical intervention with double valve replacement. Assumed meningitis as a part of the triad of Austrian syndrome was confirmed by imaging the day after hospital admission. Early diagnosis of endocarditis by obtaining the echocardiogram in the ED along with emergent surgical intervention allowed for a favorable outcome for the patient.

Rotavirus may cause life-threatening complications in untreated patients during the course of gastroenteritis. Electrolyte imbalance, bacteremia and sepsis are the most common complications of rotavirus gastroenteritis (RG). It is believed that translocation of intestinal microorganisms as a result of intestinal epithelium dysfunction is the underlying mechanism of bacteremia in RG. Although Gram-negative bacteremia has been noted as a complication in RG, Staphylococcus aureus bacteremia and endocarditis have not been reported previously. A 22-month-old boy was admitted with complaints of fever, diarrhea and dehydration. He was diagnosed with RG complicated with S. aureus bacteremia, pyomyositis and endocarditis. We call attention to these complications in patients with prolonged or late-onset fever during RG as rare complications of the disease.
