| multidrug-resistant corynebacterium striatum pneumonia in a heart transplant recipient. | corynebacterium striatum is a rare, but likely underreported, cause of serious infections in immunocompromised hosts and generally is susceptible to multiple classes of antimicrobial agents. here we report the first case of c. striatum infection in a solid organ transplant recipient. three years after heart transplantation, a 58-year-old man developed bilateral pneumonia and pulmonary embolism. he did not improve with levofloxacin, piperacillin/tazobactam, and heparin treatment. a homogeneous po ... | 2003 | 12791076 |
| septicaemia due to corynebacterium striatum: molecular confirmation of entry via the skin. | septicaemia due to corynebacterium striatum occurs infrequently. a case of c. striatum septicaemia with a known skin focus is reported in a 69-year-old male with ischaemia, refractory anaemia and treated for thyroid cancer. the characterization and typing of blood and cutaneous isolates was carried out using biochemical and dna molecular typing methods to analyse the isolates. this is the first reported case with a documented source. | 2003 | 12808083 |
| corynebacterium striatum peritoneal dialysis catheter exit site infection. | regarded as normal flora of the human skin and mucus membranes, non-diphtheria corynebacteria are frequently dismissed as contaminants or harmless colonizers. recently, the pathogenic potential of c. striatum has been realized in immunocompromised patients with indwelling medical devices and previous antibiotic exposure. | 2003 | 14579942 |
| corynebacterium suicordis sp. nov., from pigs. | nineteen strains of gram-positive, non-motile, non-spore-forming, catalase-positive, rod-shaped bacteria isolated from pigs were characterized by using biochemical, molecular chemical and molecular genetic methods. two distinct groups of organisms were discerned, based on their colonial morphology, camp (christie-atkins-munch-petersen) reaction and numerical profile by using the api coryne system. the first group (13 strains) gave a doubtful discrimination between corynebacterium striatum and co ... | 2003 | 14657140 |
| a specific bacterial aminoacylase cleaves odorant precursors secreted in the human axilla. | human axillary odor is known to be formed upon the action of corynebacteria sp. on odorless axilla secretions. the known axilla odor determinant 3-methyl-2-hexenoic acid was identified in hydrolyzed axilla secretions along with a chemically related compound, 3-hydroxy-3-methylhexanoic acid. the natural precursors of both these acids were purified from non-hydrolyzed axilla secretions. from liquid chromatography/mass spectrometry analysis, it appeared that the acids are covalently linked to a glu ... | 2003 | 12468539 |
| activities of abt-773 against listeria monocytogenes and coryneform bacteria of clinical interest. | the in vitro activities of abt-773 were evaluated against 15 listeria monocytogenes strains and 196 coryneform bacteria isolated from clinical samples. one hundred percent of the l. monocytogenes strains were inhibited by </=0.015 micro g of abt-773/ml. mics of abt-773 ( micro g/ml) at which 50% of the isolates tested were inhibited (mic(50)s) and mic(90)s for other organisms were 0.125 and 0.5 (corynebacterium amycolatum), 1 and >32 (corynebacterium jeikeium), 0.03 and >32 (corynebacterium minu ... | 2003 | 12654678 |
| report of a case with polymicrobial endocarditis related to multiresistant strains. | we present a patient with polymicrobial endocarditis who had been operated on previously for a mycotic aneurysm and was seen at the cardiology clinic because of palpitations related to effort. a transesophageal echocardiogram revealed a 15-mm vegetation on his aortic valve. staphylococcus epidermidis and corynebacterium striatum were isolated from the blood cultures. both strains were multiresistant (susceptible to 3 antibiotics at most) against chemotherapy in vitro. microbiological eradication ... | 2002 | 12673107 |
| corynebacterium striatum first reported case of prosthetic valve endocarditis. | we describe the case of a prosthetic valve endocarditis in a 72-year-old woman. corynebacterium striatum was isolated in the blood samples. this organism has been described in a few cases of native valve endocarditis, but this is the first case reported of prosthetic valve endocarditis. | 2002 | 12099749 |
| an unusual case of infective endocarditis. | a rare case of corynebacterium striatum endocarditis on a bioprosthetic aortic valve replacement, treated medically, is reported. the presentation was subacute, and initially endocarditis screening was negative. because of the failure of symptoms to settle further screening was performed which confirmed the organism in several sets of blood cultures. this emphasises the importance of persistent screening for endocarditis if the history raises any suspicion of this potentially serious infection, ... | 2002 | 12151574 |
| coryneform bacteria isolated from blood cultures and their antibiotic susceptibilities. | we aimed to determine the types of corynebacteria isolated from the blood of patients at gaziantep university hospital, turkey, and their antibiotic susceptibilities. between february 1999 and june 2001, 3530 blood samples were cultured, of which 915 were found to be positive, and these were further investigated in the bacteriology laboratory. among positive blood cultures, coryneform bacteria were identified in 31 (3.4%) isolates. of these, 16 (51.6%) were corynebacterium jeikeium, six (19.4%) ... | 2002 | 12235925 |
| activities of gemifloxacin and five other antimicrobial agents against listeria monocytogenes and coryneform bacteria isolated from clinical samples. | the in vitro activities of gemifloxacin, ciprofloxacin, ampicillin, doxycycline, gentamicin, and vancomycin were evaluated against 15 listeria monocytogenes strains and 205 coryneform bacteria isolated from clinical samples. the percentages of strains inhibited by gemifloxacin at 0.5 microg/ml were 100% (l. monocytogenes), 93.3% (brevibacterium spp.), 90% (corynebacterium minutissimum), 42.5% (corynebacterium amycolatum), 20% (corynebacterium striatum), 12.5% (corynebacterium jeikeium), and 10% ... | 2001 | 11451706 |

| pursuit of the corynebacterium striatum type strain. | the description of corynebacterium striatum (chester 1901) eberson 1918al in bergey's manual of systematic bacteriology has many inconsistencies with the identification scheme from the centers for disease control and prevention. we have studied the four c. striatum reference strains available from the american type culture collection and the national collection of type cultures and found that they fit the centers for disease control and prevention description of this species. however, it appears ... | 1993 | 8240967 |
| evidence of multiple taxa within commercially available reference strains of corynebacterium xerosis. | attempts to identify coryneform isolates resembling corynebacterium xerosis can lead clinical microbiologists to identification schemes with conflicting descriptions which result in confusing c. xerosis with corynebacterium striatum. for the present study we purchased all available american type culture collection and national collection of type cultures reference cultures of c. xerosis (n = 10) and c. striatum (n = 4) and analyzed them as follows: (i) analysis of biochemical reactions in conven ... | 1993 | 8349754 |
| corynebacterium striatum: a diphtheroid with pathogenic potential. | although nondiphtherial corynebacteria are ubiquitous in nature and commonly colonize the skin and mucous membranes of humans, they rarely account for clinical infection. corynebacterium striatum has rarely been reported to be a pathogen, causing pleuropulmonary infections and bacteremia in only immunocompromised or anatomically altered patients. we noted c. striatum to be the infecting pathogen or copathogen in six patients. to our knowledge, this report describes the first cases of c. striatum ... | 1993 | 8353242 |
| comparative chemotaxonomic studies of mycolic acid-free coryneform bacteria of human origin. | forty-two clinical isolates were classified as corynebacterium minutissimum, corynebacterium striatum, and corynebacterium cdc group i by the api coryne system. the chemotaxonomic characteristics of the isolates were determined by thin-layer chromatographic analysis. twenty-six isolates were found to have a type iv cell wall (meso-di-aminopimelic acid arabinose, galactose) but did not contain mycolic acids. these 26 isolates shared chemotaxonomic characteristics with those of mycolic acid-free r ... | 1993 | 8370733 |
