Mycobacteria causing human cervical lymphadenitis in pastoral communities in the Karamoja region of Uganda.
James Oloya,J. Opuda-Asibo,Rudovick Kazwala,A. B. Demelash,E. Skjerve,Arve Lund,Tone B Johansen,Berit Djønne +7 more
TL;DR: The isolation of M. bovis confirms the human infection with zoonotic mycobacteria in areas where consumption of raw milk and meat is routine and also confirms their increasing role in human disease and the occupational risk of infection in the transhumant ecosystem in the absence of safe drinking water and environmental contamination.
Characterisation of mycobacteria isolated from slaughter cattle in pastoral regions of Uganda.
James Oloya,James Oloya,Rudovick Kazwala,Arve Lund,J. Opuda-Asibo,B. Demelash,E. Skjerve,Tone B Johansen,Berit Djønne +8 more
TL;DR: Isolation of environmental mycobacteria could explain the high avian or non specific tuberculin reactor patterns commonly observed in pastoral cattle and suggests their pathogenic or opportunistic role in the infection of cattle with disseminated bovine tuberculous lesions.

First isolation, identification, phenotypic and genotypic characterization of Brucella abortus biovar 3 from dairy cattle in Tanzania
C. Mathew,C. Mathew,Maria Stokstad,Tone B Johansen,S. Klevar,Robinson H. Mdegela,G. L. M. Mwamengele,Patrick P. Michel,L. Escobar,David Fretin,Jacques Godfroid +10 more
TL;DR: High within-herd prevalence, isolation of the pathogen and abortion confirm that B. abortus is circulating in this herd with cattle as reservoir hosts, and a low seroprevalence in sheep and goats suggests a spillover of B. abortedus from cattle to small ruminants in the herd.
Distribution of IS1311 and IS1245 in Mycobacterium avium Subspecies Revisited
TL;DR: It is demonstrated that IS1245 is not present in Mycobacterium avium subsp.
