Rose bengal was found as positive, Tube agglutination was found to be 1/1280, 1/640 and 1/2560 positive, respectively. Bacterial identifications were used with konvantional methods (oxidase, serology) and confirmed as Brucella melitensis by external laboratory with Vitec-2. Although proper ...

Many microorganisms use a genetic regulatory mechanism to monitor their cell density and to establish a coordinated behaviour1,2,3. This regulation mechanism, initially identified in bacteria, has been termed quorum sensing (QS). It is based on the production of diffusible signal molecules (also ca...
cellulose or from glycerol and ethanol. They can be representatives of coryneform bacteria, in particular of the genus Corynebacterium. Of the genus Corynebacterium, there may be mentioned in particular the speciesCorynebacterium glutamicum, which is known among experts for its ability to produce L-ami...
The lactic acid bacteria count was performed on MRS agar (from Man, Rogosa, Sharpe, Merck, Germany) added with the indicator bromocresol (0.004%), being considered as lactic bacteria the yellow (acid producing), catalases negative and gram-positive colonies. Agar PCA (standard counting agar, ...
TMA-producing bacteria largely belong to the Firmicutes and Proteobacteria phyla, the enzymes required for this conversion are absent in Bacteroidetes. TMA is transported to the liver and metabolised into trimethylamine-N-oxide (TMAO), which has been linked to cancer via inflammation induction; other...
