PURPOSE AND METHOD The Invader assay was developed to identify 23 mycobacterial species using probes derived from the species-specific region of the 16S rRNA gene and the 16S-23S rRNA internal transcribed spacer 1 (ITS-1) region, with minor modifications of our previous study. In the present study, we compared the identification capability between the Invader assay and DNA-DNA hybridization (DD...
BACKGROUND Mycobacterium spp. is one of the most important species of zoonotic pathogens that can be transmitted from cattle to humans. The presence of these opportunistic, pathogenic bacteria in bovine milk has emerged as a public-health concern, especially among individuals who consume raw milk and related dairy products. To address this concern, the Brazilian control and eradication program ...
It has been postulated that susceptible individuals may acquire infection with nontuberculous mycobacteria (NTM) from water and aerosol exposure. This study examined household water and shower aerosols of patients with NTM pulmonary disease. The mycobacteria isolated from clinical samples from 20 patients included M. avium (5 patients), M. intracellulare (12 patients), M. abscessus (7 patients)...
BACKGROUND Non-tuberculous mycobacteria (NTM), which are ubiquitous micro-organisms occurring in humans, animals and the environment, sometimes receive public health and veterinary attention as opportunistic disease-causing agents. In Tanzania, there is limited information regarding the diversity of NTM species, particularly at the human-livestock-wildlife interface such as the Serengeti ecosys...
Mycobacteria are an important cause of morbidity in humans. Rapid and accurate mycobacterial identification is important for improving patient outcomes. However, identification of Mycobacterium species is not easy, due to the slow and fastidious growth of mycobacteria. Recently, biochemical, sequencing, and probing methods have come to be used for identification. This study compared the perform...
OBJECTIVE The present study aims at describing the frequency of nontuberculous mycobacteria (NTM) species identified through laboratory testing of samples collected from non-sterile sites (sputum), as well as its frequency in HIV-infected and non-HIV-infected individuals in the Baixada Santista region of the state of São Paulo, Brazil, in the period from 2000 to 2005. METHODS Retrospective an...
Background. Atypical mycobacteria, or nontuberculous mycobacteria (NTM), have been barely reported as infective endocarditis (IE) agents. Methods. From January 2010 to December 2013, cardiac valve samples sent to our laboratory as cases of blood culture-negative suspected IE were analyzed by 16S rDNA polymerase chain reaction (PCR). When positive for NTM, hsp PCR allowed species identificatio...
Dear Editor Mycobacterium parascrofulaceum is a member of slow-growing scotochromogenic nontuberculous mycobacteria (NTM) that can cause opportunistic infections in immunocompromised patients [1]. Only a few clinical infections with this strain have been reported to date [1-4]. We describe a case of M. parascrofulaceum pulmonary infection in a patient with bronchiectasis. To our knowledge, this...
