In Vitro Activities of the New Antitubercular Agents PA-824 and BTZ043 against Nocardia brasiliensis

Stewart Cole

The in vitro activity of PA-824 and BTZ043 against 30 Nocardia brasiliensis isolates was tested. The MIC50 and MIC90 values for PA-824 were both > 64 mu g/ml. The same values for BTZ043 were 0.125 and 0.250 mu g/ml. Given the MIC values for benzothiazinone ...

ESAT-6 secretion-independent impact of ESX-1 genes espF and espG1 on virulence of Mycobacterium tuberculosis

Stewart Cole, Jeffrey Chen

The pathogenesis of Mycobacterium tuberculosis largely depends on the secretion of the 6-kD early secreted antigenic target ESAT-6 (EsxA) and the 10-kD culture filtrate protein CFP-10 (EsxB) via the ESX-1/typeVII secretion system. Although gene products fr ...

EspD Is Critical for the Virulence-Mediating ESX-1 Secretion System in Mycobacterium tuberculosis

Stewart Cole, Neeraj Dhar, Florence Pojer, Stefanie Boy-Röttger, Jeffrey Chen

ESAT-6 system 1 (ESX-1)-mediated secretion in Mycobacterium tuberculosis is dependent on proteins encoded by the cotranscribed espA-espC-espD gene cluster. While the roles of EspA and EspC with respect to the ESX-1 secretion system have been actively inves ...

Comparative genomics of Esx genes from clinical isolates of Mycobacterium tuberculosis provides evidence for gene conversion and epitope variation

Stewart Cole, Jacques Rougemont, Swapna Uplekar

The 23-membered Esx protein family is involved in the host-pathogen interactions of Mycobacterium tuberculosis. These secreted proteins are among the most immunodominant antigens recognized by the human immune system and have thus been used to develop vacc ...

Probable zoonotic leprosy in the southern United States

Stewart Cole, Jacques Rougemont, Rahul Sharma, Philippe Busso, Adamantia Kapopoulou, Pushpendra Singh

In the southern region of the United States, such as in Louisiana and Texas, there are autochthonous cases of leprosy among native-born Americans with no history of foreign exposure. In the same region, as well as in Mexico, wild armadillos are infected wi ...

New tuberculosis drugs on the horizon

Stewart Cole

Tuberculosis (TB) remains a major global health concern whose control has been exacerbated by HIV and the emergence of multidrug-resistant (MDR-TB) and extensively drug-resistant (XDR-TB) strains of Mycobacterium tuberculosis. The demand for new and faster ...

Possible drug resistance in Mycobacterium leprae strains from Venezuela and three other South American countries was surveyed by molecular methods. None of the 230 strains from new leprosy cases exhibited drug resistance-associated mutations. However, two ...

An 86-year old female patient from northeast Mexico presented with diffuse lepromatous leprosy (DLL). Sequence analysis of four genes (rrs, rpoB, sigA and hsp65) from the skin biopsy identified Mycobacterium lepromatosis. This is the first independent conf ...

Atypical DNA recognition mechanism used by the EspR virulence regulator of Mycobacterium tuberculosis

Stewart Cole, Giovanni Dietler, Matteo Dal Peraro, Florence Pojer, Marco Stenta, Livan Bladimir Alonso Sarduy, Benjamin Blasco

The human pathogen Mycobacterium tuberculosis requires the ESX-1 secretion system for full virulence. EspR plays a key role in ESX-1 regulation via direct binding and transcriptional activation of the espACD operon. Here, we describe the crystal structures ...
