Abstract
The invention relates to a method for detecting the Gram type and the fermenting character of a bacterial strain, said method comprising: illuminating, in the wavelength range of 390 nm to 900 nm, at least one bacterium from said strain which has a natural electromagnetic response within said range; acquiring, within said range, a light intensity reflected by, or transmitted through, said illuminated bacterium; and determining the Gram type and the fermenting character of the bacterial strain according to the light intensity acquired within said range.
Claims27
A process for detecting the Gram type and the fermentative character of a bacterial strain, comprising:
- illuminating in a wavelength range 390 nm-900 nm at least one bacterium of the strain having a natural electromagnetic response in the range;
- acquiring, within the range, a luminous intensity reflected from or transmitted through the illuminated bacterium;
- and
- determining the Gram type and the fermentative character of the bacterial strain as a function of the acquired luminous intensity in the range.
A system for detecting the Gram type and the fermentative character of a bacterial strain, comprising:
- an illumination device configured to illuminate, in a wavelength range 390 nm-900 nm, at least one bacterium of the strain;
- a sensor configured to acquire, in the 390 nm-900 nm range, a luminous intensity reflected from or transmitted through the illuminated bacterium;
- and
- a computer unit configured to determine the Gram type and the fermentative character of the bacterial strain as a function of the acquired luminous intensity in the 390 nm-900 nm range.
