Abstract
Mycobacterium africanum lineage (L) 6 is an important pathogen in West Africa, causing up to 40% of pulmonary tuberculosis (TB). The biology underlying the clinical differences between M. africanum and M. tuberculosis sensu stricto remains poorly understood. We performed ex vivo expression of 2179 genes of the most geographically dispersed cause of human TB, M. tuberculosis L4 and the geographically restricted, M. africanum L6 directly from sputa of 11 HIV-negative TB patients from The Gambia who had not started treatment. The DosR regulon was the most significantly decreased category in L6 relative to L4. Further, we identified nonsynonymous mutations in major DosR regulon genes of 44 L6 genomes of TB patients from The Gambia and Ghana. Using Lebek's test, we assessed differences in oxygen requirements for growth. L4 grew only at the aerobic surface while L6 grew throughout the medium. In the host, the DosR regulon is critical for M. tuberculosis in adaptation to oxygen limitation. However, M. africanum L6 appears to have adapted to growth under hypoxic conditions or to different biological niches. The observed under expression of DosR in L6 fits with the genomic changes in DosR genes, microaerobic growth and the association with extrapulmonary disease.

The biology underlying the clinical differences between M. africanum and M. tuberculosis sensu stricto remains poorly understood. We performed ex vivo expression of 2179 genes of the most geographically dispersed cause of human TB, M. tuberculosis L4 and the geographically restricted, M. africanum L6 directly from sputa of 11 HIV-negative TB patients from The Gambia who had not started treatment. The DosR regulon was the most significantly decreased category in L6 relative to L4. Further, we identified nonsynonymous mutations in major DosR regulon genes of 44 L6 genomes of TB patients from The Gambia and Ghana. Using Lebek's test, we assessed differences in oxygen requirements for growth. L4 grew only at the aerobic surface while L6 grew throughout the medium. In the host, the DosR regulon is critical for M. tuberculosis in adaptation to oxygen limitation. However, M. africanum L6 appears to have adapted to growth under hypoxic conditions or to different biological niches. The observed under expression of DosR in L6 fits with the genomic changes in DosR genes, microaerobic growth and the association with extrapulmonary disease.</div></front></TEI><affiliations><list><country><li>Belgique</li><li>Gambie</li><li>Ghana</li><li>Suisse</li><li>États-Unis</li></country><region><li>Région du Grand Accra</li></region><settlement><li>Accra</li></settlement><orgName><li>Université du Ghana</li></orgName></list><tree><country name="Gambie"><noRegion><name sortKey="Ofori Anyinam, Boatema" sort="Ofori Anyinam, Boatema" uniqKey="Ofori Anyinam B" first="Boatema" last="Ofori-Anyinam">Boatema Ofori-Anyinam</name></noRegion><name sortKey="Antonio, Martin" sort="Antonio, Martin" uniqKey="Antonio M" first="Martin" last="Antonio">Martin Antonio</name><name sortKey="Gehre, Florian" sort="Gehre, Florian" uniqKey="Gehre F" first="Florian" last="Gehre">Florian Gehre</name></country><country name="États-Unis"><noRegion><name sortKey="Dolganov, Gregory" sort="Dolganov, Gregory" uniqKey="Dolganov G" first="Gregory" last="Dolganov">Gregory Dolganov</name></noRegion><name sortKey="Davis, J Lucian" sort="Davis, J Lucian" uniqKey="Davis J" first="J Lucian" last="Davis">J Lucian Davis</name><name sortKey="Garcia, Benjamin J" sort="Garcia, Benjamin J" uniqKey="Garcia B" first="Benjamin J" last="Garcia">Benjamin J.
