| abiotrophia defectiva bleb-associated endophthalmitis confirmed with 16s ribosomal rna sequencing. | one recognized complication of trabeculectomy with visually devastating potential is blebitis. we present a case of a 74-year-old woman with a culture and polymerase chain reaction-positive abiotrophia defectiva bleb-associated endophthalmitis. abiotrophia defectiva is a rare but possible cause of endophthalmitis secondary to blebitis and should be considered in culture-negative cases. prompt identification, hence directed eradication, of the causative organism in such visually threatening cases ... | 2015 | 23970342 |
| abiotrophia defectiva causing infectious crystalline keratopathy and corneal ulcer after penetrating keratoplasty: a case report. | infectious crystalline keratopathy is commonly caused by streptococcus viridans and other gram positive organisms. we present the first case of infectious crystalline keratopathy that developed into a corneal ulcer and grew abiotrophia defectiva which responded well to topical and systemic antimicrobial therapy and did not require re-grafting. a 78-year-old man underwent penetrating keratoplasty for pseudophakic bullous keratopathy. he presented 1.5 years later with infectious crystalline kerato ... | 2013 | 23514629 |
| intravascular catheter-related bloodstream infection caused by abiotrophia defectiva in a neutropenic child. | bacteraemia and endocarditis are the most frequently reported clinical infections due to abiotrophia defectiva species. this species has been rarely implicated in infections in neutropenic patients. we report a rare case of long-term venous catheter-related infection caused by a. defectiva that occurred in a febrile child who had neutropenia and langerhans' cell histiocytosis. | 2013 | 23378563 |
| [a case with abiotrophia defectiva isolated from postoperative blood culture of a patient with diffuse peritonitis]. | we have recently detected abiotrophia defectiva (a. defectiva) from postoperative blood culture of a patient with diffuse peritonitis. pleomorphic gram positive rod appearance and no growth on a standard sheep blood agar led us to suspect aerotolerant anaerobe. from the test results of simplified identification kit for anaerobes, we tentatively reported clostridium tertium (c. tertium) to the clinician. however, the analysis of 16srrna sequence proved it to be a. defectiva. when gram positive co ... | 2012 | 23198534 |
| meningitis caused by abiotrophia defectiva: case report and literature review. | the genus abiotrophia comprises fastidious gram-positive bacteria previously classified as nutritionally variant streptococci (nvs). the isolation of nvs from the central nervous system (cns) is very rare. we describe a case of meningitis due to abiotrophia defectiva in a patient who underwent a total hip arthroplasty 4 days previously. it is possible that the organism could be introduced through the spinal anesthesia. we also review all cases of cns infections caused by nvs. | 2013 | 22915347 |
| bullous impetigo associated with abiotrophia defectiva in an immunocompetent adult. | infection of humans by abiotrophia defectiva, a nutritionally variant streptococcus, most commonly takes the form of endocarditis, though a variety of other manifestations ranging from central nervous system abscesses to orthopaedic infections have been seen. we report here what we believe is the first case of bullous impetigo associated with this organism. | 2012 | 22493280 |
