Capnocytophaga sp., a microaerophilic gram-negative isolate of the human oral cavity, has previously been reported to cause sinusitis, empyema, wound infections, conjunctivitis, subphrenic abscess, osteomyelitis, bacteremia, cervical abscess, and endocarditis. We report the unusual case of infection with this organism at the anastamotic site of a splenorenal portosystemic vascular shunt. In this case, the pathogenesis is presumed to be bacteremia related to mucosal trauma from endoscopic injection sclerotherapy or bacteremia secondary to dental infection. The characteristics and antibiotic sensitivities of Capnocytophaga are reviewed.

Although the first Aeromonas strain was described by Zimmermann as early as in 1890, it took 60 years until Caselitz established human pathogenicity of strains then called "Vibrio jamaicensis". Since then, and especially in the last 10 years, there have been increasing numbers of reports on different infections caused by members of the genus Aeromonas. These include sepsis; meningitis; cellulitis; necrotizing fasciitis; ecthyma gangrenosum; pneumonia; peritonitis; conjunctivitis; corneal ulcer; endophthalmitis; osteomyelitis; suppurative arthritis; myositis; subphrenic abscess; liver abscess; cholecystitis and/or ascending cholangitis; urinary tract infection; endocarditis; ear, nose, and throat infections; balanitis; etc. The role of Aeromonas in gastrointestinal disease is very controversial. Increasing epidemiological data suggest that these organisms play a major role in enteric infections, but so far enteropathogenicity has not been demonstrable in experiments where volunteers were given high numbers of Aeromonas possessing different virulence factors. Virulence factors include hemolysin(s), enterotoxin(s), hemagglutinins, invasivity, and others; but these are not found more frequently in strains isolated from patients with diarrhea than from healthy controls. Whether there is a correlation between species and disease remains to be elucidated and requires more information about the taxonomy of this genus.

The authors present a rare case of subacute endocarditis caused by Gemella morbillorum. A 72-year-old man, with a history of hypertension, aortic valve disease and upper and lower endoscopy six months previously, was admitted due to fever and abdominal pain. He also complained of long-standing dyspnea on exertion and petechiae on his lower limbs. Imaging scans showed a consolidation in the lower left lung field, a splenic infarct and a left subphrenic abscess. Transthoracic echocardiogram findings were highly suggestive of endocarditis affecting three valves, with destruction of the mitral valve anterior leaflet. G. morbillorum was identified in three blood cultures and was considered the etiologic pathogen. Due to the patient's worsening condition, he underwent cardiac surgery, aiming to control the infection and to resolve the associated mechanical complications. This case highlights the need for a complete and thorough history to arrive at likely diagnostic hypotheses that, together with complementary exams, will lead to correct diagnosis and the prompt institution of appropriate therapy.

We describe an unusual case of subphrenic abscess complicating a central venous catheter infection caused by Pseudomonas aeruginosa in a 59-year-old woman undergoing hemodialysis. The diagnosis was made through computed tomography, and Pseudomonas aeruginosa was isolated from the purulent drainage of the subphrenic abscess, the catheter tip and exit site, and the blood culture samples. A transesophageal echocardiography showed a large tubular thrombus in superior vena cava, extending to the right atrium, but no evidence of endocarditis or other metastatic infectious foci. Catheter removal, percutaneous abscess drainage, anticoagulation, and antibiotics resulted in a favourable outcome.
