1. Prevalence of bovine tuberculosis in the Aksu Region of Xinjiang, China, between 1985 and 2016
RESUMO Prevalência de infecção por tuberculose bovina em gado na prefeitura de Aksu determinada por teste cutâneo tuberculínico (TST) entre 1985 e 2016 foi avaliada. O gado foi analisado de acordo com região, padrão alimentar, rebanho e idade. Um total de 890009 animais foram testados, com prevalência de 0,13% de tuberculose bovina (1172/890009). Dif

2. Risk factors for human Mycobacterium bovis infections in an urban area of Brazil
BACKGROUND The World Health Organization (WHO) has classified human zoonotic tuberculosis (TB) due to Mycobacterium bovis as a neglected issue in the developing world. In a recent cross-sectional study in Brazil, three of 189 TB patients presented with a coinfection of M. bovis and M. tuberculosis and were selected as cases for this study. OBJECTIVE The ai

3. Nontuberculous mycobacteria in milk from positive cows in the intradermal comparative cervical tuberculin test: implications for human tuberculosis infections
ABSTRACT Although the tuberculin test represents the main in vivo diagnostic method used in the control and eradication of bovine tuberculosis, few studies have focused on the identification of mycobacteria in the milk from cows positive to the tuberculin test. The aim of this study was to identify Mycobacterium species in milk samples from cows positive to

4. Diagnosis of mycobacteria in bovine milk: an overview
ABSTRACT Tuberculosis remains as the world’s biggest threat. In 2014, human tuberculosis ranked as a major infectious disease by the first time, overcoming HIV death rates. Bovine tuberculosis is a chronic disease of global distribution that affects animals and can be transmitted to humans by the consumption of raw milk, representing a serious public healt

5. Comparative study of Mycobacterium bovis primary isolation methods
Abstract For the definitive diagnosis of bovine tuberculosis, isolation of the etiologic agent is required. However, there is no consensus on the best methodology for isolation of Mycobacterium bovis in Brazil. This study evaluated the most used decontaminants and culture media in the country, in order to identify the best combination for the Brazilian sampl

6. Stable expression of Mycobacterium bovis antigen 85B in auxotrophic M. bovis bacillus Calmette-Guérin
BACKGROUND Bovine tuberculosis (TB) is a zoonotic disease caused by Mycobacterium bovis, responsible for causing major losses in livestock. A cost effective alternative to control the disease could be herd vaccination. The bacillus Calmette-Guérin (BCG) vaccine has a limited efficacy against bovine TB, but can improved by over-expression of protective ant

7. Validation of a real-time PCR assay for the molecular identification of Mycobacterium tuberculosis
Mycobacterium tuberculosis is the major cause of tuberculosis in humans. This bacillus gained prominence with the occurrence of HIV, presenting itself as an important opportunistic infection associated with acquired immunodeficiency syndrome (AIDS). The current study aimed to develop a real-time PCR using Eva Green technology for molecular identification of

8. Molecular typing of Mycobacterium bovis isolates: a review
Mycobacterium bovis is the main causative agent of animal tuberculosis (TB) and it may cause TB in humans. Molecular typing of M. bovis isolates provides precise epidemiological data on issues of inter- or intra-herd transmission and wildlife reservoirs. Techniques used for typing M. bovis have evolved over the last 2 decades, and PCR-based methods such as s

9. Direct detection of Mycobacterium tuberculosis complex in bovine and bubaline tissues through nested-PCR
Post-mortem bacterial culture and specific biochemical tests are currently performed to characterize the etiologic agent of bovine tuberculosis. Cultures take up to 90 days to develop. A diagnosis by molecular tests such as PCR can provide fast and reliable results while significantly decreasing the time of confirmation. In the present study, a nested-PCR sy

10. Molecular typing of Mycobacterium bovis isolated in the south of Brazil
Bovine tuberculosis is a major infectious disease of the cattle. In this study, 85 M. bovis isolates from 162 lymph nodes, obtained from a herd of cattle on a farm in southern Brazil, were evaluated using spoligotyping and VNTR. The strains were grouped into five clusters and five orphans, showing a heterogenic genetic profile, what could represent diverse g

11. Genotyping Mycobacterium bovis from cattle in the Central Pampas of Argentina: temporal and regional trends
Mycobacterium bovis is the causative agent of bovine tuberculosis (TB), a disease that affects approximately 5% of Argentinean cattle. Among the molecular methods for genotyping, the most convenient are spoligotyping and variable number of tandem repeats (VNTR). A total of 378 samples from bovines with visible lesions consistent with TB were collected at sl

12. Análise leucométrica em bovinos tuberculinizados e sua aplicação no monitoramento da leucose enzoótica em rebanhos do Estado de Pernambuco.
Leucose Enzoótica (LEB) e Tuberculose bovina (TB) comprometem o estado imunitário dos rebanhos, especialmente pelo potencial imunodepressor do Vírus da Leucose Bovina (VLB). Inúmeros fatores interferem nos valores leucométricos dos bovinos, porém, pouco se sabe dos efeitos da TB sobre os mesmos. O objetivo com o estudo foi avaliar o leucograma de bovin
