| native-valve endocarditis due to cdc coryneform group anf-3: report of a case and review of corynebacterial endocarditis. | endocarditis due to a bacterium of cdc coryneform group anf-3 developed in the native aortic valve of a patient without predisposing factors other than valvular calcification. a review of the literature indicates that corynebacteria are an increasingly important cause of endocarditis. problems in identification and treatment remain. techniques for the culture and quick identification of these organisms and effective regimens for treatment of the infections they cause are needed. | 1994 | 7893876 |
| evaluation of the applicability of amplified rdna-restriction analysis (ardra) to identification of species of the genus corynebacterium. | the 16s rrna genes (rdna) of 50 strains belonging to 26 different coryneform bacterial species and genomospecies and of the type strain of rhodococcus equi were enzymatically amplified. amplified rdna restriction analysis (ardra) with the enzymes alui, cfoi and rsai was carried out. the combination of the ardra patterns obtained after restriction with these three different enzymes enabled the differentiation between the following species: corynebacterium accolens (number of strains = 2), c. afer ... | 1995 | 8584787 |

| [a case of community-acquired pneumonia caused by corynebacterium propinquum]. | corynebacterium propinquum, which is classified as corynebacterium anf-3, has not yet been described as a cause of the respiratory infections. in this paper, we reported a case of 67-year-old immunocompetent male with community-acquired pneumonia caused by c. propinquum. our study suggested that gram staining of the pulurent sputum was the most important diagnostic tool to determine the pathogenecity of this organism. | 2003 | 12872696 |
| [three adult cases with corynebacterium propinquum respiratory infections in a community hospital]. | corynebacterium propinquum, which is included in corynebacterium group anf-3, exists as a commensal in the oral flora. this organism has not yet been fully recognized as a respiratory pathogen. we previously reported that the first case with respiratory infection caused by c. propinquum. on the other hand, corynebacterium pseudodiphtheriticum is recognized as a causative organism in respiratory infections. recently we experienced two cases with c. propinquum respiratory infections in our hospita ... | 2004 | 15103912 |
| isolation of coryneform bacteria from blood cultures of patients at a university hospital in saudi arabia. | coryneform bacteria have been increasingly recognized as opportunistic pathogens in recent years. the aim of this study is to identify and determine the antimicrobial susceptibility of coryneform bacteria isolated from blood cultures of patients seen at king khalid university hospital (kkuh), riyadh, kingdom of saudi arabia and review the literature. | 2004 | 15322601 |

| nirk and nirs nitrite reductase genes from non-agricultural forest soil bacteria in thailand. | the genetic heterogeneity of the nitrite reductase gene (nirk and nirs) fragments from denitrifying prokaryotes in a non-agricultural forest soil in thailand was investigated using soil samples from the plant germplasm-royal initiation project area in kanchanaburi province, thailand. soil bacteria were screened for denitrification activity and 13 (from 211) positive isolates were obtained and further evaluated for their ability to reduce nitrate and to accumulate or reduce nitrite. three species ... | 2011 | 21475726 |
| non-diphtheriae corynebacterium species: an emerging respiratory pathogen. | the purpose of the study was to describe the microbiological and clinical features of ten cases of lower respiratory tract infection due to corynebacterium striatum, corynebacterium propinquum and corynebacterium pseudodiphtheriticum. respiratory samples were recovered from hospitalised patients who were diagnosed of pneumonia and exacerbations of chronic respiratory infections. the samples were gram-stained and seeded on conventional bacterial growing media. bacteria were identified by matrix-a ... | 2012 | 23271676 |
| corynebacterium propinquum endocarditis: a confounding presentation of a rare entity. | infective endocarditis is rarely caused by corynebacterium species. we report a unique case of corynebacterium propinquum endocarditis in an otherwise healthy individual, and it is the first example of this organism causing culture-negative endocarditis. conflicting clinical and microbiological data led to the use of sequencing to confirm the causative organism. this case illustrates c. propinquum as a cause of infective endocarditis, and it demonstrates the utility of ancillary molecular diagno ... | 2017 | 28376415 |
| corynebacterium propinquum: a rare cause of prosthetic valve endocarditis. | nondiphtheria corynebacterium species are often dismissed as culture contaminants, but they have recently become increasingly recognized as pathologic organisms. we present the case of a 48-year-old male patient on chronic prednisone therapy for rheumatoid arthritis with a history of mitral valve replacement with prosthetic valve. he presented with fever, dizziness, dyspnea on exertion, intermittent chest pain, and palpitations. transesophageal echocardiography revealed two medium-sized densitie ... | 2016 | 27891149 |

| corynebacterium propinquum as the first cause of infective endocarditis in childhood. | we here present a 7-year-old girl with ventricular septum defect and ventriculoatrial communication, who developed infective endocarditis (ie) due to corynebacterium propinquum in the tricuspid valve. the patient was admitted because of an 8-day history of fever. transthoracic echocardiogram showed non-pedunculated vegetation on the septal leaflet of the tricuspid valve. gram-positive coryneform bacteria grew from three consecutive sets of blood cultures taken on admission. c. propinquum was con ... | 2014 | 24486166 |
| corynebacterium propinquum associated with acute, nongonococcal urethritis. | corynebacterium propinquum is usually considered part of the normal human oropharyngeal flora and is rarely responsible for clinical infection. we report here what seems to be the first case of acute purulent urethral discharge in a young iranian man with urethritis acquired after orogenital contact. attention should be devoted to less common nondiphtheriae corynebacterium species for differential diagnosis. | 2013 | 24275738 |
| emendation of the description of the species corynebacterium propinquum to include strains which produce urease. | corynebacterium propinquum is a gram-positive rod occasionally recovered from clinical infections which, according to 16s rrna gene sequencing, is most closely related (>99% sequence similarity) to corynebacterium pseudodiphtheriticum. the two species are very similar biochemically, commonly differentiated by a single test, the detection of urease, where strains of c. propinquum are described as being urease-non-producing and strains of c. pseudodiphtheriticum are described as urease-producing. ... | 2013 | 23104363 |
