Kalifa Bojang,Paul Milligan,Margaret Pinder,Laurence Vigneron,Ali Alloueche,Kent E. Kester,W. Ripley Ballou,David J. Conway,William H. H. Reece,Philip Gothard,Lawrence Yamuah,Martine Delchambre,Gerald Voss,Brian Greenwood,Adrian V. S. Hill,Keith P. W. J. McAdam,Nadia Tornieporth,Joe Cohen,Tom Doherty +18 more
TL;DR: RTS,S/AS02 is safe, immunogenic, and is the first pre-erythrocytic vaccine to show significant protection against natural P. falciparum infection in semi-immune adult men in The Gambia.
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
Maternal plasma viral RNA levels determine marked differences in mother-to-child transmission rates of HIV-1 and HIV-2 in The Gambia.
Diarmuid O'Donovan,Koya Ariyoshi,Paul Milligan,Martin O. C. Ota,Lawrence Yamuah,Ramu Sarge-Njie,Hilton Whittle +6 more
TL;DR: Low maternal HIV-2 RNA levels, which on average are 37-fold less than in HIV-1 infection, relate to the low MCT rate of HIV- 2, and risk factors for transmission that applied equally to both viruses are determined.
Journal ArticleDOI
High Prevalence of Bovine Tuberculosis in Dairy Cattle in Central Ethiopia: Implications for the Dairy Industry and Public Health
Rebuma Firdessa,Rea Tschopp,Rea Tschopp,Alehegne Wubete,Melaku Sombo,Elena Hailu,Girume Erenso,Teklu Kiros,Lawrence Yamuah,Martin Vordermeier,R. Glyn Hewinson,Douglas B. Young,Stephen V. Gordon,Mesfin Sahile,Abraham Aseffa,Stefan Berg +15 more
TL;DR: This study showed an overall BTB herd prevalence of 50% in intensive dairy farms in Addis Ababa and surroundings, signalling an urgent need for intervention to control the disease and prevent zoonotic transmission of M. bovis to human populations consuming dairy products coming from these farms.
