TL;DR: Coalescent analyses indicate that MTBC emerged about 70,000 years ago, accompanied migrations of anatomically modern humans out of Africa and expanded as a consequence of increases in human population density during the Neolithic period, consistent with MTBC displaying characteristics indicative of adaptation to both low and high host densities.
Journal ArticleDOI
Mycobacterial Lineages Causing Pulmonary and Extrapulmonary Tuberculosis, Ethiopia
Rebuma Firdessa,Stefan Berg,Elena Hailu,Esther Schelling,Balako Gumi,Girume Erenso,Endalamaw Gadisa,Teklu Kiros,Meseret Habtamu,Jemal Hussein,Jakob Zinsstag,Brian D. Robertson,Gobena Ameni,Amanda J. Lohan,Brendan J. Loftus,Iñaki Comas,Sebastien Gagneux,Rea Tschopp,Lawrence Yamuah,Glyn Hewinson,Stephen V. Gordon,Douglas B. Young,Abraham Aseffa +22 more
TL;DR: A novel phylogenetic lineage of M. tuberculosis strongly associated with the Horn of Africa is reported, with a minimal role for M. bovis in patients with lymph node or pulmonary tuberculosis in Ethiopia.
Journal ArticleDOI
The Burden of Mycobacterial Disease in Ethiopian Cattle: Implications for Public Health
Stefan Berg,Rebuma Firdessa,Meseret Habtamu,Endalamaw Gadisa,Araya Mengistu,Lawrence Yamuah,Gobena Ameni,Martin Vordermeier,Brian D. Robertson,Noel H. Smith,Howard Engers,Douglas B. Young,R. Glyn Hewinson,Abraham Aseffa,Stephen V. Gordon +14 more
TL;DR: It is revealed that bTB is widely spread throughout Ethiopia, albeit at a low prevalence, and provides underpinning evidence for public health policy formulation.
Journal ArticleDOI
The glycosyltransferases of Mycobacterium tuberculosis—roles in the synthesis of arabinogalactan, lipoarabinomannan, and other glycoconjugates
TL;DR: This review reflects on these entities from the perspective of their synthesis, particularly the structural and functional aspects of the glycosyltransferases (GTs) of M. tuberculosis, the dominating group of enzymes responsible for the terminal stages of their biosynthesis.
Journal ArticleDOI

TL;DR: The identified clonal complex of Mycobacterium bovis present at high frequency in cattle in population samples from several sub-Saharan west-central African countries is suggested to be geographically localized, albeit to several African countries, and to be the result of an original introduction into cows naïve to bovine tuberculosis.
