1. Complete plasmid sequence carrying type IV-like and type VII secretion systems from an atypical mycobacteria strain
The genus Mycobacterium is highly diverse and ubiquitous in nature, comprehending fast- and slow-growing species with distinct impact in public health. The plasmid-mediated horizontal gene transfer represents one of the major events in bacteria evolution. Here, we report the complete sequence of a 160,489 bp circular plasmid (pCBMA213_2) from an atypical and

2. Avaliação do potencial das formigas como vetores mecâncios de micobactérias em hospital especializado na assistência de pacientes de tuberculose no Estado de São Paulo / Evaluation of ants as potential mechanical vectors of mycobacteria in a hospital specializing in assistance to TB patients, the state of São Paulo
Introduction- Urbanization triggers numerous disorders, such as the dissemination of arthropods and, consequently, dissemination of diseases transmitted by them. Some ant species are very adaptable to the human environment. At hospitals, once they are mechanical vectors of bacteria, and the diversity of species found in these environments, they can represent

3. Rapid tests for the detection of the Mycobacterium abscessus subsp. bolletii strain responsible for an epidemic of surgical-site infections in Brazil
A single strain of Mycobacterium abscessus subsp. bolletii, characterised by a particular rpoB sequevar and two highly related pulsed field gel electrophoresis patterns has been responsible for a nationwide outbreak of surgical infections in Brazil since 2004. In this study, we developed molecular tests based on polymerase chain reaction restriction-enzyme a

4. A survey of the bacterial diversity in the cup filler of dental chair units
Water from the cup filler of dental chair units (CFDC) was observed to contain sphingomonads, environmental mycobacteria and methylobacteria, among other minor bacteria. Some of the bacteria detected are recognized opportunistic pathogens. Some of these, tended to persist over time.

5. Immunodiagnosis potential of M. tuberculosis CFP-10 for active tuberculosis / Anáilise do potencial diagnóstico do anígeno CFP-10 expresso pelo M. tuberculosis.
The use of specific antigens of M. tuberculosis is extremely important for early diagnosis of tuberculosis and to control the spread of mycobacteria in the population. The CFP-10 is an antigen that is present in M. tuberculosis, but is absent in M. bovis of BCG and environmental mycobacteria. So, the objective of this study was to determine whether the immun

7. Detecção e identificação de micobactérias em corpos de água destinados à captação para abastecimento urbano da cidade de São Carlos - SP.
Foram analisadas 59 amostras de água provenientes do Ribeirão do Feijão, Rio do Monjolinho e da Estação de Tratamento de Água (SAAE), das quais 51 foram positivas para o isolamento de micobactérias. Dos dois procedimentos de descontaminação, obtivemos 83,0% de amostras positivas para isolamento com ácido sulfúrico e 39,0% com cloreto de cetilpirid

8. Mycobacterium avium restriction fragment lenght polymorphism-IS IS1245 and the simple double repetitive element polymerase chain reaction typing method to screen genetic diversity in Brazilian strains
Simple double repetitive element polymerase chain reaction (MaDRE-PCR) and Pvu II-IS1245 restriction fragment length polymorphism (RFLP) typing methods were used to type 41 Mycobacterium avium isolates obtained from 14 Aids inpatients and 10 environment and animals specimens identified among 53 mycobacteria isolated from 237 food, chicken, and pig. All envir

9. Health Impacts of Environmental Mycobacteria†
Environmental mycobacteria are emerging pathogens causing opportunistic infections in humans and animals. The health impacts of human-mycobacterial interactions are complex and likely much broader than currently recognized. Environmental mycobacteria preferentially survive chlorination in municipal water, using it as a vector to infect humans. Widespread chl

10. Environmental Factors Affecting the Occurrence of Mycobacteria in Brook Waters
To evaluate the impact of environmental factors on the occurrence of environmental mycobacteria, viable counts of mycobacteria were measured in samples of brook water collected from 53 drainage areas located in a linear belt crossing Finland at 63° north latitude. The numbers of mycobacteria were correlated with characteristics of the drainage area, climati

11. Failure of the Mycobacterium bovis BCG Vaccine: Some Species of Environmental Mycobacteria Block Multiplication of BCG and Induction of Protective Immunity to Tuberculosis
The efficacy of Mycobacterium bovis bacillus Calmette-Guérin (BCG) vaccine against pulmonary tuberculosis (TB) varies enormously in different populations. The prevailing hypothesis attributes this variation to interactions between the vaccine and mycobacteria common in the environment, but the precise mechanism has so far not been clarified. Our study demon

12. Isolation of mycobacteria from patients seropositive for the human immunodeficiency virus (HIV) in south east England: 1984-92.
BACKGROUND--Tuberculosis and other mycobacterial infections are well recognised complications of HIV infection and surveillance is thus required. METHODS--All mycobacteria isolated from HIV positive subjects and referred to the Public Health Laboratory Service South East Regional Tuberculosis Centre (SERTC) from the first such case in 1984 until the end of 1
