Abstract: A device for a colorimetric diagnosis of urinary tract infections, characterized in that it comprises at least one vial wherein a liquid analysis mixture is housed comprising a water part and an organic part immiscible with the water part and having a density lower than that of the water part. The water part is composed of a reagent mixture comprising (a) nutrient substances comprising an amino acid source selected from the group consisting of meat infusions or peptones, vegetable peptones, casein hydrolysates, tryptose, tryptones and yeast extract; (b) at least one redox indicator with a potential ranging from ?100 to +500 mV; and (c) a buffer system able to maintain the pH in a range from 6.0 to 8.0. The reagent mixture comprises from 94.0 to 99.9% by weight of the nutrient substances and from 0.1 to 6.0% by weight of the redox indicator.

Abstract: A method for detecting a bacterial load comprising adding a sample for analysis to an analysis reagent in a sterilized reaction container, thermostatting the reaction container at a temperature of between 25 and 45° C., and verifying the change in colouring of the analysis reagent. The analysis reagent is an aqueous solution comprising amino acids chosen from the group consisting of meat peptones, vegetable peptones, casein hydrolysates, tryptose, tryptones and yeast extract; glucides chosen from monometric or oligomeric glucides metabolisable by micro-organisms; a buffer system suitable for maintaining the pH between 5.5 and 8.5; a redox indicator with potential between ?250 and +250 mV and/or a pH indicator with colour change interval between pH 4.0 and pH 9.0; and a water-immiscible organic liquid compound having a lower density than water and suitable for separating the aqueous phase from a gaseous phase existing prior to the analysis or formed during the reaction.
