Mycobacterium bovis is the etiologic agent of bovine tuberculosis, a chronic infectious disease affecting livestock, wild animals, and sometimes humans. We report here three draft genome sequences of Mycobacterium bovis strains of spoligotypes SB0821 and SB0134, isolated from wildlife but circulating in wildlife-livestock multihost systems, and SB0121, circulating exclusively in cattle.
A live, attenuated form of Mycobacterium bovis, bacillus Calmette-Guérin (BCG), is commonly used as intravesical immunotherapy for non-invasive urothelial bladder carcinoma. While complications are rare, dissemination can occur. A case of mycotic aortic aneurysm following BCG administration with recovery of Mycobacterium bovis in culture is reported. A review of the published experience with th...
Brucella abortus and Mycobacterium bovis are zoonotic pathogens that cause Brucellosis and Tuberculosis in cattle respectively. Besides being a serious public health threat, these agents cause significant economic losses throughout the world. Here we use the fluorescence polarization capabilities of the SynergyTM 2 Multi-Mode Microplate Reader to run Brucella and Mycobacterium bovis antibody de...
The aim of this study was to define epitopes of Mycobacterium bovis from ESAT-6 (early secretory antigen of 6 kDa) recognized by CD8+ T lymphocytes from cows naturally infected with Mycobacterium bovis. We found that bovine CD8+ T cells recognized 10 out of 11 ESAT-6 peptides tested.
The Esx and PE/PPE families of proteins are among the most immunodominant mycobacterial antigens and have thus been the focus of research to develop vaccines and immunological tests for diagnosis of bovine and human tuberculosis, mainly caused by Mycobacterium bovis and Mycobacterium tuberculosis, respectively. In non-tuberculous mycobacteria (NTM), multiple copies of genes encoding homologous ...
Here we report the complete genome sequences of field isolates of Mycobacterium bovis and the related mycobacterial species, Mycobacterium caprae. The genomes of three M. bovis (MB1, MB3, MB4) and one M. caprae (MB2) field isolates with different virulence, prevalence, and host distribution phenotypes were sequenced.

Mycobacterium bovis is best identified by screening those isolates of the Mycobacterium tuberculosis complex that have any pyrazinamide (PZA) resistance, using a confirmatory test such as spoligotyping, biochemical testing, or genomic deletion analysis. The sensitivity for detection of M. bovis is lowered to 82% when only PZA-monoresistant isolates are screened.
Pathogenic mycobacteria must acquire iron in the host in order to multiply and cause disease. To do so, they release abundant quantities of siderophores called exochelins, which have the capacity to scavenge iron from host iron-binding proteins and deliver it to the mycobacteria. In this study, we have characterized the exochelins of Mycobacterium bovis, the causative agent of bovine and occasi...
Mycobacterium bovis causes tuberculosis in animals and humans. Infected cows can transmit the bacillus to humans via milk. Milk also contains lactic acid bacteria (LAB). LAB isolated from milk were put in milk cultures together with spiked M. bovis. Different LAB had different abilities to reduce M. bovis counts, as M. bovis was undetectable in some while it persisted in two of the cultures.
