1. 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

2. Mycobacterium fortuitum: uma alternativa para a etapa de pré-adsorção no sorodiagnóstico da paratuberculose
Ensaios de sorodiagnóstico de paratuberculose (ELISA) utilizam Mycobacterium phlei na etapa de pré-adsorção para diminuir reações inespecíficas. Uma vez que M. fortuitum é uma das micobactérias atípicas mais isoladas no Brasil, o objetivo central deste estudo foi averiguar a possibilidade de sua utilização como antígeno da etapa de pré-adsorç�

3. Paratuberculose: uma atualização
A Paratuberculose é uma enterite crônica que afeta ruminantes, causada por Mycobacterium avium paratuberculosis (Map). A doença é cosmopolita e determina importantes perdas econômicas. No Brasil, o agente foi isolado nas regiões Sul e Nordeste além do Rio de Janeiro, mas não há estudos epidemiológicos suficientes sobre sua ocorrência. O isolamento

4. Estudo de mycobacterium phlei (ATCC 11758) como agente agregante para hematita e quartzo
Several microorganisms have been studied in flotation, sedimentation and filtration processes for several minerals, with positive results. Studies show Mycobacterium phlei as flocculant agent and potential collector for hematite. The objective of this work is to study the influence of the addition of the bacteria Mycobacterium phlei (ATCC 11758) upon sedimen

6. Immunotherapy of experimental cancer by intralesional injection of emulsified nonliving mycobacteria: comparison of Mycobacterium bovis (BCG), Mycobacterium phlei, and Mycobacterium smegmatis.
Mycobacterium bovis (BCG), Mycobacterium phlei, and Mycobacterium smegmatis were each tested in emulsified form for their potency to cause regression of transplants of a syngeneic murine fibrosarcoma and of a syngeneic guinea pig hepatoma. On a weight basis, M. phlei and M. smegmatis were as effective as BCG in causing tumor regression. M. phlei and M. smegm

7. Specificity of Isoniazid on Growth Inhibition and Competition for an Oxidized Nicotinamide Adenine Dinucleotide Regulatory Site on the Electron Transport Pathway in Mycobacterium phlei
The mechanism of action of isoniazid (INH) on saprophytic and atypical mycobacteria is thought to be different from that on Mycobacterium tuberculosis because higher concentrations are required to be effective in these species. In this investigation, M. phlei was inhibited by INH at a concentration of 25 μg/ml. Benzoic acid hydrazide (BZH) and nicotinic aci

8. Differentiation of Catalases in Mycobacterium phlei on the Basis of Susceptibility to Isoniazid: Association with Peroxidase and Acquired Resistance to Isoniazid
Mycobacterium phlei contains two catalase activities and a single peroxidase activity. The latter is associated with one of the catalases. The single catalase-peroxidase enzyme accounted for 75% of the total catalase activity and was lost upon acquisition of resistance to the antitubercular drug isoniazid (INH). Heat-treated (68°C) wild-type cells showed si

9. RELATIONSHIP OF THE HEXOSE MONOPHOSPHATE SHUNT TO THE ENDOGENOUS METABOLISM OF CELL-FREE EXTRACTS OF MYCOBACTERIUM PHLEI
Sutton, W. B. (The Lilly Research Laboratories, Indianapolis, Ind.). Relationship of the hexose monophosphate shunt to the endogenous metabolism of cell-free extracts of Mycobacterium phlei. J. Bacteriol. 85:476–484. 1963.—The endogenous reduction of 2,6-dichlorophenol-indophenol (DPIP) by cell-free extracts of Mycobacterium phlei has been linked to the

10. Differences in the Utilization of Glycerol and Glucose by Mycobacterium phlei
A basic difference was found in the kinetics of uptake and utilization of glucose and glycerol by washed suspensions of Mycobacterium phlei. With glucose, the rates of uptake, respiration, and assimilation were saturated at low external substrate concentration. With glycerol, these rates were found to increase with increasing substrate concentration and did

11. Fatty Acid Synthetase Activity in Mycobacterium phlei: Regulation by Polysaccharides
The multienzyme complex from Mycobacterium phlei which catalyzes the synthesis of long chain fatty acids from acetyl-CoA and malonyl-CoA requires a heat-stable fraction (stimulating factor, SF) for activity. Fractionation of heat-treated M. phlei extracts affords two stimulatory subfractions, one of which (SF2) can be replaced by FMN. The other (SF1) is furt
