TB interpretation with the new algorithm of mIGRA using either QFT-PHA or Con A + PWM as positive mitogens.

Data was obtained from the 8-round prospective studies of 100 naturally TB-contacted cynomolgus macaques in month-0 (M0), month-4 (M4), month-7 (M7), month-14 (M14), month-17 (M17), month-20 (M20), month-26 (M26), and month-29 (M29). At M4, M7, M14, M17, M20, M26, and M29, blood collection was not applicable in some monkeys because of the animal loss or animal death occurred; thus, the total studied cases were less than 100 animals. The asterisk (*) indicates 2 positive cases infected with M.tb, which died in M9-M10.
