FIGURE 3
The biocidal action of ALG-AgNPs against different Mtb strains measured as a suppression of colony numbers relative to PBS treatment (control). Four Mtb strains were incubated with PBS or different amounts of ALG-AgNPs for 0 and 7 days. Bacterial growth was determined by counting the colony forming units (CFU) of (A) H37Rv (standard reference strain), (B) W6 (Beijing strain), (C) KVGH264 (MDR), and (D) TCHL017 (XDR). MDR: Multidrug-resistant TB; XDR: extensively drug-resistant TB. The data are expressed as log10 CFU/ml and represent the mean ± SEM of 3 experiments. ***p < 0.001.
