Nonfermenting coryneform bacteria identified as Brevibacterium spp. were isolated from routine clinical specimens. Four strains were derived from peritoneal fluid and has presumably been involved in the pathogenesis of continuous ambulatory peritoneal dialysis peritonitis. Another five isolates most probably represented skin contaminants. Cell wall and lipid analyses confirmed the genus identif...

Uptake of manganese by Brevibacterium ammoniagenes ATCC 6872 was energy dependent and obeyed saturation kinetics (Km = 0.65 microM; Vmax = 0.12 mumol/min per g [dry weight]). Uptake showed optima at 27 degrees C and pH 9.5. 54Mn2+ accumulated by the cells was released by treatment with toluene or by exchange for unlabeled manganese ions, via an energy-dependent process. Co2+, Fe2+, Cd2+, and Zn...

The occurrence and incidence of gram-positive organisms which possess some biochemical and serological characteristics in common with salmonellae are described. These organisms were encountered as contaminants in various food products as well as in feces. Their growth in various Salmonella enrichment media, typical Salmonella-like growth on differential selective media, biochemical similarities...

It is concluded from experiments with (S)-[C015NH2]glutamine and [15N]ammonium sulphate that the biosynthesis of iodinin (1), in Brevibacterium iodinum, and of phenazine-1-carboxylic acid (7), in Pseudomonas aureofaciens, is primarily from a single nitrogen source (glutamine) and that the phenazines are constituted by combination of two units of the same precursor, as 5. Some observations are m...

Brevibacterium spp. are catalase-positive, non-spore-forming, non motile, aerobic Gram-positive rods that were considered apathogenic until a few reports of infections in immunocompromised patients had been published. To the best of our knowledge, this is the first report of B. casei catheter-related bloodstream infection in a child with acute leukemia. We aim to enhance the awareness of pediat...
