A lipophilic coryneform bacterium isolated from a blood culture from a patient with signs of septicaemia was characterized by means of phenotypic and molecular taxonomic methods. Chemotaxonomic investigations revealed the presence of cell-wall chemotype IV and short-chain mycolic acids, which are consistent with the genus Corynebacterium. The isolate was characterized biochemically by the very ...

Here we report the genome sequencess of four Corynebacterium pseudotuberculosis strains. These include a strain isolated from a patient with C. pseudotuberculosis pneumonia (48252), a strain isolated from pus in goat (Ft_2193/67), a laboratory strain originating from strain Ft_2193/67 (CS_10), and the draft genome of an equine reference strain, CCUG 27541.

Corynebacterium accolens is rarely isolated as a human pathogen. We describe here a case of C. accolens isolated from a breast abscess in a patient previously diagnosed with granulomatous mastitis. The possible association of Corynebacterium accolens and granulomatous mastitis in this patient is discussed.

By the use of 16S rRNA gene sequence analysis we identified 28 of 31 Corynebacterium spp. isolated from bone and joint infections, including species never before isolated in such infections. Phenotypic analysis led to the correct identification of 8 of 31. 16S rRNA gene sequence analysis appears to be a good technique for identification of clinical strains of Corynebacterium spp.

Strains of Corynebacterium ulcerans and Corynebacterium pseudotuberculosis (Corynebacterium ovis) were examined for the production of diphtheria toxin. A majority of C. ulcerans strains (25 of 37) and 1 C. pseudotuberculosis strain (1 of 14) gave a positive Elek test for diphtheria toxin, and for all strains but 1, production of diphtheria toxin was inhibited at the same level of Fe2+ as was th...

Bacteria of the genus Corynebacterium are important primary and opportunistic pathogens. Many are zoonotic agents. In this report, phenotypic (API Coryne analysis), genetic (rpoB and 16S rRNA gene sequencing), and physical methods (MS) were used to distinguish the closely related diphtheroid species Corynebacterium ulcerans and Corynebacterium pseudotuberculosis, and to definitively diagnose Co...

The bio-materials of four marine mangrove medicinal plants viz., Aegiceras Corniculatum (AGC), Excoecariaagallocha (EA), Rhizophoramucronata (RM) and Xylocarpusgranatum (XG) are extracted with methanol and hexane. These extracts are submitted to the antibacterial activity towards the strains:Bacillus puvuilis, Bacillus subtilis, Bacillus coagulans, Staphylococcus aureus, Bacillus licheniformis,...

BACKGROUND Corynebacterium species are recognized as uncommon agents of endocarditis, but little is known regarding species-specific risk factors and outcomes in Corynebacterium endocarditis. METHODS Case report and Medline search of English language journals for cases of Corynebacterium endocarditis. Inclusion criteria required that cases be identified as endocarditis, having persistent Cory...

Identification of coryneform bacteria to the species level is important in certain circumstances for differentiating contamination and/or colonization from infection, which influences decisions regarding clinical intervention. However, methods currently used in clinical microbiology laboratories for the species identification of coryneform bacteria are often inadequate. We evaluated the MicroSe...

Acid methanolysates of 104 strains of coryneform and related bacteria were examined for mycolic acids by thin-layer chromatography and mass spectrometry. The mycolic acids of Corynebacterium sensu stricto strains were not uniform in size and structure, and considerable variation existed within the approximate limiting range of C22 to C36. Two species, Corynebacterium bovis and 'Corynebacterium ...
