Abstract: When bacteria growth is determined in the related art using an ATP method, the bacteria growth is determined, based on an increase or a decrease in live bacteria ATP with the lapse of a culture time. Accordingly, it is necessary to measure the live bacteria ATP multiple times while antimicrobial susceptibility culture is carried out. It takes time and labor in sample preparation for each measurement, and it is difficult to quickly obtain an antimicrobial susceptibility result. Therefore, according to the present invention, the presence or absence of antimicrobial susceptibility of bacteria is determined, based on an ATP luminescence amount derived from dead bacteria in a culture liquid.
