Efficacy of disinfectants to M. tuberculosis stains. Each M. tuberculosis stain was exposed to the disinfectants for 1 min at room temperature. The bacteria were incubated in Middlebrook 7H9 broth for 14 days at 37 °C. Bacterial growth was measured by 16S rRNA targeted real-time qPCR. Control was not exposure by any disinfectants. Dashed line indicates the genome copy number on the day of inoculation. ADEG, alkyldiaminoethylglycine-HCl (0.2 % W/V); CG, chlorhexidine gluconate (0.1 % W/V); PI, povidine iodine (10 mg/ml as active iodine); BK, benzalkonium-HCl (0.1 % W/V); OX, oxydol (3 % W/V); CS, cresol soap (2 % V/V); EtOH, ethanol (70 % V/V); and BK + EtOH, benzalkonium-HCl (0.1 % W/V) + ethanol (70 % V/V). The results are expressed as means ± SD. *: p <0.05 (v.s. genome number on the day of inoculation). Black bars: the disinfectant inhibited growth of M. tuberculosis (effective disinfectant). White bars: the disinfectant did not inhibit growth of the bacteria (not effective)
