M. tuberculosis strain 1254 wild type (WT) and its isogenic delta Rv3662c-Rv3665c KO (opp KO) and complemented opp::opp were cultured in vitro, in liquid 7H9 media supplemented with OADC and 0.05% Tween 80, 0.5% glycerol, in a 150 mL volume, contained in roller bottles, incubated at 37oC. Growth wa...
ORGANISM(S): Mycobacterium tuberculosis 
E. histolytica trophozoites (3x105) harvested in exponential growth phase were transferred to 25 cm² cell culture flasks and grown at 37°C for 24 h. Then, parasites were exposed to irradiation in a 254 nm UV-transilluminator (BioDoc-It Imaging System (UVP)) for 30 min at 4°C (Valdés et al., 2014) an...

Background: Conflicting results have been reported about the role of the two-component sensor and transcriptional regulator DosS/DosR, controlling the expression of the dormancy DosR regulon, for in vivo virulence of M. tuberculosis. Here, we have used a new approach to further analyze the relevance...
ORGANISM(S): Mycobacterium tuberculosis 
In this report we demonstrated that under aerobic conditions, Mycobacterium bovis BCG expressing an hsp60-driven second copy of the hypoxia-related transcriptional regulator DosR increased 2-fold or greater the expression of 38 out of the 48 genes belonging to the DosR regulon, including the latency...
