The alternative synonymous codons in Corynebacterium glutamicum, a well-known bacterium used in industry for the production of amino acid, have been investigated by multivariate analysis. As C. glutamicum is a GC-rich organism, G and C are expected to predominate at the third position of codons. Indeed, overall codon usage analyses have indicated that C and/or G ending codons are predominant in...

lnstitut fur Meereskunde an der Universitat Kiel, Abteilung Marine Mikrobiologie, Dusternbrooker Weg 20, D-24105 Kiel, Germany Sequences of the 16s rDNA from all available type strains of Chromatium species have been determined and were compared to those of other Chromatiaceae, a few selected Ectothiorhodospiraceae and Escherichia coli. The clear separation of Ectothiorhodospiraceae and Chromat...

In a prospective study to evaluate the influence of secondary bacterial infection on the evaluation of cutaneous leishmaniasis, in Corte de Pedra (Bahia), we isolated Corynebacterium diphtheriae in 7 (8.3%) out of 84 patients with ulcers studied. Due to the small number of patients with the presence of the bacteria in the ulcer, we could not conclude whether Corynebacterium diphtheriae behaves ...

Nineteen new Corynebacterium species or taxa described since 1995 have been associated with human disease. We report the characteristics of 72 strains identified as or most closely resembling 14 of these newer, medically relevant Corynebacterium species or taxa, as well as describe in brief an isolate of Corynebacterium bovis, a rare pathogen for humans. The bacteria studied in this report were...

In the present study, synthesis, characterization, and the antibacterial activity of silver nanoparticles from native isolate of Corynebacterium glutamicum has been reported. Silver nanoparticles were synthesized by challenging the dried biomass of C. glutamicum with aqueous diamine silver ([Ag (NH3)2]+) containing 1 mM AgNO3. Synthesized silver nanoparticles (AgNPs) were characterized by ultra...

To date the genus Corynebacterium comprises 88 species. More than half of these are connected to human and animal infections, with the most prominent member of the pathogenic species being Corynebacterium diphtheriae, which is also the type species of the genus. Corynebacterium species are characterized by a complex cell wall architecture: the plasma membrane of these bacteria is followed by a ...

Encrusted cystitis is a very rare chronic inflammatory disease of the bladder characterized by precipitation and incrustation of phosphate and ammonium-magnesium salts on the vescical mucosa, caused by urinary infection due to urolithic microorganisms. Corynebacterium urealyticum or Corynebacterium group D2, a multiple antibiotic-resistant urea-splitting bacterium, is the most frequently incrim...
