heterogeneity within human-derived centers for disease control and prevention (cdc) coryneform group anf-1-like bacteria and description of corynebacterium auris sp. nov.recently, centers for disease control and prevention coryneform group anf-1 bacteria were described as corynebacterium afermentans, and group anf-1-like bacteria were described as turicella otitidis. over a 1.5-year period 10 strains of a previously undescribed, gram-positive, rod-shaped organism that was not partially acid fast and resembled anf-1-like bacteria were isolated from different pediatric patients with ear infections. these previously undescribed coryneform bacteria exhibited a disti ...19957547292
prosthetic valve endocarditis caused by corynebacterium afermentans subsp. lipophilum (cdc coryneform group anf-1).corynebacteria are important causes of endocarditis in individuals with valvular prostheses. we report the first published case of prosthetic valve endocarditis caused by the newly defined species corynebacterium afermentans subsp. lipophilum (former cdc coryneform group anf-1). the isolate was recovered from a perivalvular abscess specimen and 5 of 15 bactec blood cultures after 7 to 15 days of incubation. the isolation, identification, and susceptibility testing of corynebacterium species are ...19957751392
coryneform bacteria isolated from middle ear fluid.nineteen strains of facultatively anaerobic gram-positive rods isolated in pure culture from middle ear fluids were identified. all effusions were collected by tympanocentesis in children with acute otitis media. identification of microorganisms to the genus level was done by studying the cell wall composition. sixteen strains contain meso-diaminopimelic acid and arabinogalactan polymer but lack mycolic acids; therefore, these strains do not belong to a previously described taxon. because of sim ...19938315016
taxonomic study of corynebacterium group anf-1 strains: proposal of corynebacterium afermentans sp. nov. containing the subspecies c. afermentans subsp. afermentans subsp. nov. and c. afermentans subsp. lipophilum subsp. nov.we have determined the cell wall composition, guanine-plus-cytosine (g+c) contents of the dna, rrna gene restriction patterns, and the levels of dna-dna relatedness of 11 strains identified biochemically as centers for disease control (cdc) corynebacterium group absolute nonfermenter 1 (corynebacterium group anf-1). for seven of these strains, growth is abundant on 5% sheep blood agar, which differentiates them from the four other strains, whose growth requires a lipid supplement such as tween 8 ...19938494739
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 ...19958584787
corynebacterium afermentans subsp. lipophilum: multiple abscess formation in brain and liver.corynebacterium afermentans, a species recently identified, has previously been isolated from human blood cultures. we report the case of a previously healthy 39-year-old man who developed a brain abscess and a liver abscess due to corynebacterium afermentans subsp. lipophilum. the liver abscess penetrated through the diaphragm to cause pleural effusion and periostitis of the ribs. we believe this is the first reported case of disseminated infection with abscess formation due to this organism.19958685648
identification of turicella otitidis isolated from a patient with otorrhea associated with surgery: differentiation from corynebacterium afermentans and corynebacterium auris.turicella otitidis is a newly described coryneform bacterium isolated from middle ear fluids. we report here on the diagnosis of a strain isolated from otorrhea. the api coryne system (biomérieux, marcy i'etoile, france) used alone failed to differentiate t. otitidis, corynebacterium afermentans, and corynebacterium auris (anf group). biochemical tests such as dnase, enzymatic reactions (api zym; biomérieux), and carbon substrate assimilation tests (biotype 100; biomérieux) allow presumptive ide ...19968880538
species identities and antimicrobial susceptibilities of corynebacteria isolated from various clinical sources.over a 14-month period, 415 clinical isolates of coryneform gram-positive rods were recovered from various sources and identified to the species level according to recent identification schemes. corynebacterium urealyticum, corynebacterium striatum, corynebacterium amycolatum, and corynebacterium jeikeium predominated, accounting for 63% of all isolates. corynebacterium accolens, corynebacterium striatum, corynebacterium argentoratense, corynebacterium propinquum and corynebacterium pseudodiphth ...19968894575
corynebacterium mastitidis sp. nov., isolated from milk of sheep with subclinical mastitis.fourteen strains of a hitherto unknown catalase-positive, aerobic, gram-positive coryneformlike organism were isolated from the milk of sheep with subclinical mastitis from different regions of spain. the strains phenotypically closely resembled one another and biochemically were similar to corynebacterium urealyticum and corynebacterium afermentans subsp. lipophilum. the results of chemotaxonomic investigations were consistent with membership in the genus corynebacterium, and comparative 16s rr ...19979336910
