13. 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

14. Mycobacteria mobility shift assay: a method for the rapid identification of Mycobacterium tuberculosis and nontuberculous mycobacteria
The identification of mycobacteria is essential because tuberculosis (TB) and mycobacteriosis are clinically indistinguishable and require different therapeutic regimens. The traditional phenotypic method is time consuming and may last up to 60 days. Indeed, rapid, affordable, specific and easy-to-perform identification methods are needed. We have previously

15. Mycobacterium neoaurum causing prosthetic valve endocarditis: a case report and review of the literature
Mycobacterium neoaurum is a rare cause of bacteremia, and infection usually occurs in an immunocompromised host in the setting of an indwelling catheter. Prosthetic valve endocarditis due to non-tuberculous mycobacteria typically carries a dismal prognosis; we report a case ofM. neoaurum prosthetic valve endocarditis with favorable response to antimicrobial

16. Mycobacterium fortuitum-related lymphadenitis associated with the varicella-zoster virus
Lymphadenitis caused by non-tuberculous mycobacteria is an uncommon manifestation in immunocompetent individuals. Here, we report a case of Mycobacterium fortuitum infection in a previously healthy 9-year-old patient who developed cervical lymphadenitis evolving to a suppurative ulcer associated with a varicella-zoster virus infection. We discuss the relatio

17. Rapid detection and differentiation of mycobacterial species using a multiplex PCR system
Introduction The early diagnosis of mycobacterial infections is a critical step for initiating treatment and curing the patient. Molecular analytical methods have led to considerable improvements in the speed and accuracy of mycobacteria detection. Methods The purpose of this study was to evaluate a multiplex polymerase chain reaction system using mycobac

18. Nontuberculous mycobacteria in respiratory samples from patients with pulmonary tuberculosis in the state of Rondonia, Brazil
The main cause of pulmonary tuberculosis (TB) is infection with Mycobacterium tuberculosis (MTB). We aimed to evaluate the contribution of nontuberculous mycobacteria (NTM) to pulmonary disease in patients from the state of Rondônia using respiratory samples and epidemiological data from TB cases. Mycobacterium isolates were identified using a combination o

19. Incidence of tuberculous and non-tuberculous mycobacteria, differentiated by multiplex PCR, in clinical specimens of a large general hospital
OBJECTIVE: To determine the incidence of Mycobacterium tuberculosis complex and non-tuberculous mycobacterial isolates in the routine setting of a large general hospital using an "in-house" multiplex polymerase chain reaction method and to establish a paradigm for the definitive identification of mycobacteria isolated using semi-automated equipment. METHODS:

20. Mycobacterium aurum keratitis: an unusual etiology of a sight-threatening infection
Atypical fast-growing Mycobacterium species are usually identified after laser-assisted in situ keratomileusis, cosmetic surgeries, and catheter-related, pulmonary or soft tissue infections. We herein present the case of a 56-year-old man with purulent discharge, redness, and foreign body sensation in his left eye. He underwent two surgeries that partially c

21. Avaliação de técnicas moleculares para identificação de micobactérias não causadoras de tuberculose / Evaluation of molecular techniques for non-tuberculous mycobacteria identification
As micobactérias compreendem um grupo de organismos que são heterogêneos em termos de metabolismo, crescimento, nicho ambiental, epidemiologia, patogenicidade, distribuição geográfica e associação com doenças. O diagnóstico micobacteriológico é atualmente um desafio aos laboratórios. Com a descrição de novas espécies de micobactérias nos úl

22. Validation of an immunochromatographic assay kit for the identification of the Mycobacterium tuberculosis complex
The performance of the immunochromatographic assay, SD BIOLINE TB Ag MPT64 RAPID®, was evaluated in Madagascar. Using mouse anti-MPT64 monoclonal antibodies for rapid discrimination between the Mycobacterium tuberculosis complex and nontuberculous mycobacteria, the kit was tested on mycobacteria and other pathogens using conventional methods as the gold sta

23. Evaluation of rapid techniques for the detection of mycobacteria in sputum with scanty bacilli or clinically evident, smear negative cases of pulmonary and extra-pulmonary tuberculosis
The objective of the current study was to compare two rapid methods, the BBL Mycobacteria Growth Indicator Tube (MGIT TM) and Biotec FASTPlaque TB TM (FPTB) assays, with the conventional Löwenstein-Jensen (LJ) media assay to diagnose mycobacterial infections from paucibacillary clinical specimens. For evaluation of the clinical utility of the BBL MGIT TM an

24. High prevalence of drug-resistant tuberculosis and other mycobacteria among HIV-infected patients in Brazil: a systematic review
There is a little-noticed trend involving human immunodeficiency virus (HIV)-infected patients suspected of having tuberculosis: the triple-treatment regimen recommended in Brazil for years has been potentially ineffective in over 30% of the cases. This proportion may be attributable to drug resistance (to at least 1 drug) and/or to infection with non-tuberc
