25. Control of Mycobacterium fortuitum and Mycobacterium intracellulare infections with respect to distinct granuloma formations in livers of BALB/c mice
Mycobacterium fortuitum is a rapidly growing nontuberculous Mycobacterium that can cause a range of diseases in humans. Complications from M. fortuitum infection have been associated with numerous surgical procedures. A protective immune response against pathogenic mycobacterial infections is dependent on the granuloma formation. Within the granuloma, the ma

26. Antimycobacterial neolignans isolated from Aristolochia taliscana
Tuberculosis (TB - Mycobacterium tuberculosis) is an ancient infectious disease that has appeared once again as a serious worldwide health problem and now comprises the second leading cause of death resulting from a single infection. The prevalence of multidrug resistance (MDR) TB is increasing and therapeutic options for treatment are not always accessible;

27. Comparative radiological features of disseminated disease due to Mycobacterium tuberculosis vs non-tuberculosis mycobacteria among AIDS patients in Brazil
Background: Disseminated mycobacterial disease is an important cause of morbidity and mortality in patients with HIV-infection. Nonspecific clinical presentation makes the diagnosis difficult and sometimes neglected. Methods: We conducted a retrospective cohort study to compare the presentation of disseminated Mycobacterial tuberculosis (MTB) and non-tubercu

28. Surto de infecção após videoscopias causado por Mycobacterium massiliense em Goiânia-GO : análise molecular e determinação da suscetibilidade aos antimicrobianos / Emergence of nosocomial Mycobacterium massiliense infection in Goiás, Brazil
Durante os últimosd anos o número de infecções causadas por microbactérias não-tuberculosas (MNT) tem aumentado principalmente devido às infecções oportunistas em indivíduos imunocompormetidos e ao aprimoramento das técnicas de cultura e identificação das MTN. Mycobacterium massilienese é um organismo emergente, associado a infecções de ferid

29. Estudo do mecanismo de transferência horizontal da sequência de inserção IS1245, específica de Mycobacterium avium, para Mycobacterium kansasii / Study of the mechanism of horizontal transfer of insertion sequence IS1245, specific of Mycobacterium avium, to Mycobacterium kansasii
Mycobacterium avium and Mycobacterium kansasii are non-tuberculous mycobacteria frequently isolated in infections from HIV positive patients. In a previous study from our laboratory, a mixed culture of M. avium and M. kansasii from a bone marrow isolate of an HIV positive patient was studied. The analysis of isolated colonies allowed the detection of the ins

30. In vitro synergic effect of ²-lapachone and isoniazid on the growth of Mycobacterium fortuitum and Mycobacterium smegmatis
Nontuberculous mycobacteria are ubiquitous and saprophytic organisms that have been implicated in a wide spectrum of diseases due to an increasing number of immunocompromised patients. The natural resistance of atypical mycobacteria to classical antituberculous drugs has encouraged research into new chemotherapeutic agents and drug combinations. The aim of t

32. Use of in-house PCR for identification of Mycobacterium tuberculosis in BACTEC broth cultures of respiratory specimens
We evaluated the ability of a PCR assay to identify Mycobacterium tuberculosis complex (MTBC) from positive BACTEC® 12B broth cultures. A total of 107 sputum samples were processed and inoculated into Ogawa slants and BACTEC® 12B vials. At a growth index (GI) > 30, 1.0 ml of the 12B broth was removed, stored, and assayed with PCR. Molecular results were co

In order to focus on the importance of laboratorial diagnosis of extrapulmonary mycobacteria, except renal, we employed the polymerase chain reaction (PCR). Clinical samples (body fluids) were tested by PCR for the presence of Mycobacterium tuberculosis complex (MTB) and nontuberculous mycobacteria (MNTB). We compared the results obtained through the PCR wit

34. Mycobacterium bovis identification by a molecular method from post-mortem inspected cattle obtained in abattoirs of Mato Grosso do Sul, Brazil
The presence of Mycobacterium bovis in bovine carcasses with lesions suggestive of tuberculosis was evaluated. Seventy-two carcass samples were selected during slaughter inspection procedures in abattoirs in the state of Mato Grosso do Sul, Brazil. Seventeen (23.6%) of samples showed colonies suggestive of mycobacteria that were confirmed to be acid-fast bac

35. Infection with the Mycobacterium avium complex in patients without predisposing conditons: a case report and literature review
Nontuberculous Mycobacteria (NTM), especially Mycobacterium avium-intracellulare complex (MAC), has been considered responsible for human disease, especially in HIV patients. Nevertheless, it has been diagnosed in immunocompetent elderly men, frequently with previous pulmonary disease: chronic obstructive lung disease (COPD), complications of tuberculosis, p

Nontuberculous mycobacteria are ubiquitous and saprophytic organisms that have been implicated in a large spectrum of diseases due to immunocompromised patients. Indeed, the emergence of multidrug-resistant strains and the natural resistance of atypical mycobacteria to the classical antituberculous drugs have encouraged researches in order to obtain new chem
