Mycobacterium tuberculosis and M. bovis infect animals and humans. Their epidemiology in developed and developing countries differs, owing to differences in the implementation of preventive measures (World Health Organization, 1999). Identification and differentiation of these closely related mycobacterial species would help to determine the source, reservoirs of infection, and disease burden d...

BACKGROUND Tuberculosis (TB) is the leading cause of death worldwide from a single infectious agent. An ability to detect the Mycobacterium tuberculosis complex (MTC) in clinical material while simultaneously differentiating its members is considered important. This allows for the gathering of epidemiological information pertaining to the prevalence, transmission and geographical distribution o...

Spoligotyping was used to examine IS6110-positive DNA of 26 Mycobacterium bovis, M. bovis BCG and M. bovis subsp. caprae non-viable isolates stored up to 10 years. All of these isolates were previously identified by biochemical tests and all 17/17 tested isolates were earlier found virulent for guinea pigs. In total seven spoligotypes, designated S1–S7, were detected and compared with the spoli...

Bovine tuberculosis (BTB), a zoonotic infection of cattle caused by Mycobacterium bovis, results in losses of $3 billion to the global agricultural industry and represents the fourth most important livestock disease worldwide. M. bovis as a source of human infection is likely underreported due to the culture medium conditions used to isolate the organism from sputum or other sample sources. We ...

Panama remains free of zoonotic tuberculosis caused by Mycobacterium bovis. However, DNA fingerprinting of 7 M. bovis isolates from a 2013 bovine tuberculosis outbreak indicated minimal homology with strains previously circulating in Panama. M. bovis dispersion into Panama highlights the need for enhanced genotype testing to track zoonotic infections.

We reviewed 86 cases of human immunodeficiency virus and tuberculosis coinfection; 34.9% were caused by Mycobacterium bovis. Patients with M. bovis infection were more likely to have advanced immunosuppression (CD4 T cell counts ≤200 cells/μL). Hispanic ethnicity, male sex, and abdominal disease were strongly associated with M. bovis disease.

Vaccination of mice with Mycobacterium bovis culture filtrate proteins (CFP), prepared in a variety of adjuvants (aluminum hydroxide, Quil-A, and dimethyldioctyldecyl ammonium bromide [DDA]), provided significant protection against an aerosol challenge of virulent M. bovis. Additionally, vaccination with CFP in DDA or Quil-A did not sensitize mice to M. bovis purified protein derivative.

Mycobacterium bovis infection of cats is exceedingly rare in regions where bovine tuberculosis is not endemic. We describe the diagnosis and clinical management of pulmonary M. bovis infection in 2 indoor-housed cats and their association with at least 1 M. bovis-infected human in Texas, USA, in September 2012.

BACKGROUND The European badger is an important wildlife reservoir of Mycobacterium bovis implicated in the spread of bovine tuberculosis in the United Kingdom and Ireland. Infected badgers are known to shed M. bovis in their urine and faeces, which may contaminate the environment. To aid bovine tuberculosis control efforts novel diagnostic tests for detecting infected and shedding badgers are n...
