Image analysis technique was applied to identify morphological changes of pellets from white-rot fungus Trametes versicolor on agitated submerged cultures during the production of exopolysaccharide (EPS) or ligninolytic enzymes. Batch tests with four different experimental conditions were carried out. Two different culture media were used, namely yeast medium or Trametes defined medium and the ...

1. Oleate hemoglobin agar is a good selective culture medium for Bacillus influenzae. 2. Bacillus influenzae has been cultivated from the mouth of 93 per cent of cases of influenza and bronchopneumonia. 3. Bacillus influenzae was present at the time of this study in the mouths of 43 per cent of normal individuals. 4. The types of pneumococci found associated with the complicating bronchopneumon...

Bacterial pellets from Enterobacteriaceae positive blood cultures prepared using ammonium chloride were tested for rapid detection of β-lactamase using the commercial βLACTA test and read after 30 minutes. During 7 months, 137 bacterial pellets were tested prospectively. βLACTA test exhibited a sensitivity of 75% and a specificity of 100% for the detection of third-generation cephalosporin resi...

OBJECTIVE Epithelial wound repair assures the recovery of the epithelial barrier after wounding. During wound healing epithelial cells migrate to cover the wound surface. For healing of skin wounds the skin keratinocytes can be replaced by oral mucosa epithelial cells grown in vitro. The presented experiments were carried out in order to compare the proliferation, morphology, and migration betw...
