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. |
