Ochrobactrum anthropi is a non-glucose fermentative, aerobic gram-negative bacillus, formerly known as Achromobacter sp or CDC group Vd. It has been isolated from the environment and from infections in usually immunocompromised human beings. The documented infections frequently involved catheter related bacteremia whereas endophthalmitis, urinary infections, meningitis, endocarditis, hepatic abscess, osteochondritis, pelvic abscess and pancreatic abscess were rarely involved. Here it is presented the case of a male patient aged 69 years with sustained hypotension, four day febrile syndrome, chill, lavish perspiration and sensorium deterioration. He had type 2 diabetes and antecedent of cerebrovascular accident. A double-lumen dialysis catheter was present due to chronic renal insufficiency. An episode of catheter-related bloodstream infection was documented by using Bact-Alert Blood Culture System and Differential-Time-to-Positivity Method for central venous catheter versus peripheral blood cultures (>120 min). Once removed, it was confirmed through Maki semi quantitative technique (>15 FCU). The microorganism was identified by API 20NE and Vitek 1 as Ochrobactrum anthropi.

Bilateral endogenous endophthalmitis is a rare complication of endocarditis. We present the case of a 72-year-old female who presented with heart failure and bilateral endogenous endophthalmitis. Endocarditis was confirmed on transesophageal echocardiography. All cultures were negative, but 16S rDNA sequencing on vitreal aspirates identified Streptococcus dysgalactiae as the likely pathogen.

Human infections with Streptococcus equi subspecies zooepidemicus, a group C streptococcus, are very rare and are generally associated with contact with horses, and consumption of unpasteurized milk products, goat cheese or pork. In most cases S zooepidemicus leads to fulminant infections. The case of a middle-aged woman who had sporadic contact with horses is described in the present report. She developed a bacteremia with severe and extensive complications that included meningitis, mitral endocarditis and blindness due to bilateral endophthalmitis. To the authors' knowledge, this is the first reported case of an endophthalmitis due to S zooepidemicus. Because of a penicillin allergy, the patient was treated with ceftriaxone and rifampin over six weeks and survived. The present case report highlights the severe complications associated with S zooepidemicus infection.

We report a rare case of endogenous endophthalmitis caused by Streptococcus equisimilis. A 74-year-old woman with endocarditis developed endogenous endophthalmitis. The patient underwent emergency mitral valvuloplasty, and intravitreal and subconjunctival injections of vancomycin and meropenem. After the surgery, she was treated with topical antibiotics, ointment, intravenous gentamicin and intravenous penicillin G potassium. The causative organism was identified as S. equisimilis. S. equisimilis should be considered as a pathogen that can cause severe endogenous endophthalmitis.

BACKGROUND: Endogenous endophthalmitis is a rare disease and its visual prognosis is poor. CASE REPORTS: We present two patients, a 60-year-old man and a 53-year-old man, who developed endogenous endophthalmitis caused by Gram-positive organisms but recovered good vision after antibiotics and vitrectomy. RESULTS: The first patient complained of ocular pain and visual decrease in his right eye. Ophthalmoscopy showed inflammation in the anterior chamber and vitreous opacities. Antibiotic was administrated systemically, and blood culture detected Streptococcus anginosus. He underwent successful heart surgery for endocarditis and total dental extraction for severe gingivitis. Vitrectomy was performed 36 days after the onset and vision improved from 0.02 to 0.7. The second patient was referred for acute visual decrease in his left eye. Severe iritis and vitreous opacities were observed, and systemic examination showed acute pyelitis and prostatic abscesses. Blood cultures detected Staphylococcus sp., and systemic antibiotics were given. Vitrectomy was performed 12 days after the onset, and vision improved from 0.06 to 1.2. CONCLUSIONS: We conclude that the rapid treatment with systemic antibiotics for the organisms at the primary site, and the vitrectomy, even though delayed, can lead to a good recovery of vision.

Although Escherichia coli is among the most common causes of Gram-negative bacteraemia, infectious endocarditis (IE) due to this pathogen is rare. A 67-y-old male without a previous medical history presented with a new mitral regurgitation murmur and persisting E. coli bacteraemia in spite of broad-spectrum intravenous antibiotics. Transthoracic and transoesophageal echocardiography revealed a severe mitral endocarditis. E. coli DNA was identified from the mitral valve and the vegetation, and no other pathogen was found. The case was further complicated by spondylodiscitis and bilateral endophthalmitis. Extra-intestinal pathogenic E. coli (ExPEC) are able to colonize tissue outside the gastrointestinal tract and contain a variety of virulence factors that may enable the pathogens to invade and induce infections in the cardiac endothelia. In these cases echocardiography as the imaging technology is of paramount importance for the correct diagnosis and treatment.

The authors report a rare presentation of bilateral Klebsiella pneumoniae endophthalmitis in an ambulatory patient without other known medical conditions. A 51-year-old Chinese woman presented with severe bilateral reduction in vision, photophobia, pain, and eyelid swelling. Hospital admission and evaluation revealed vitreous, blood, and urine cultures positive for K. pneumoniae (K1 serotype). Additional work-up revealed endocarditis, multiple liver abscesses, brain abscesses, and left lobar pneumonia. The patient underwent multiple bilateral intravitreal antibiotic injections. Ultimate visual acuity was no light perception in both eyes. K. pneumoniae endogenous endophthalmitis is a severe but potentially subclinical disease. Early diagnosis requires a high index of suspicion and recognition of risk factors including Asian ancestry and other sources of systemic infection including, most commonly, liver abscess.

Actinomyces neuii, a species first described in 1994, has proven to be an exception in this genus on account of its aerobic growth, microscopic morphology (no branching), and the types and location of infections. Abscesses and infected atheromas are the most frequent types of infections, followed by infected skin structures, endophthalmitis, and bacteremias, including endocarditis. They are most likely of endogenous origin. To date, approximately 100 cases have been recorded in the literature. Intra-abdominal and intrathoracic infections, however, have not yet been described, and cases of classical actinomycosis seem to be extremely rare. Prognosis has generally been good with antibiotic and/or surgical treatment. Susceptibility to antibiotics has paralleled that of other Actinomyces spp.

This lesson reports the case of endophthalmitis, a rare presentation of infective endocarditis (IE), two months following cardiac surgery. Although inflammatory markers were increased, blood cultures were negative. Transoesophageal echocardiography demonstrated an aortic root abscess. Culture of tissue obtained at surgery revealed the infective organism to be Aspergillus fumigatus, a rare cause of IE in the immunocompetent patient.

Disseminated sporotrichosis occurs in individuals with impaired cellular immunity, such as in cases of neoplasia, transplantation, diabetes, and especially, acquired immunodeficiency syndrome. This report presents a 32-year-old Brazilian human immunodeficiency virus (HIV)-infected patient who developed a protracted condition of disseminated sporotrichosis with endocarditis, bilateral endophthalmitis, and lymphatic involvement. He needed cardiac surgery to replace the mitral valve. Sporothrix brasiliensis isolates were recovered from cultures of subcutaneous nodules and mitral valve fragments. Species identification was based on classical and molecular methods. The patient received amphotericin B for 52 days and subsequently, oral itraconazole. He remains asymptomatic, and he is on maintenance therapy with itraconazole. Despite his positive clinical outcome, he developed bilateral blindness. To our knowledge, this case is the first report of endocarditis and endophthalmitis caused by S. brasiliensis.
