1. Proteus mirabilis biofilm - Qualitative and quantitative colorimetric methods-based evaluation
Proteus mirabilis strains ability to form biofilm is a current topic of a number of research worldwide. In this study the biofilm formation of P. mirabilis strains derived from urine of the catheterized and non-catheterized patients has been investigated. A total number of 39 P. mirabilis strains isolated from the urine samples of the patients of dr Antoni J

2. Pro-embryogenic cell viability and cell suspension of Byrsonima intermedia A. Juss. / Viabilidade de CÃlulas PrÃ- EmbriogÃnicas e SuspesÃo Celular de Murici-Pequeno
The Murici-pequeno (Byrsonima intermedia A. Juss) is a fruitful medicinal species of Cerrado which presents difficulties to be propagated by conventional methods. This fact makes necessary the development of alternative methodologies of propagation for this species. In this work it was studied the in vitro seedlings growth according to residual effects of se

3. Determination of myocardial infarction size in rats by echocardiography and tetrazolium staining: correlation, agreements, and simplifications
Triphenyltetrazolium chloride (TTC) staining and echocardiography (ECHO) are methods used to determine experimental myocardial infarction (MI) size, whose practical applicability should be expanded. Our objectives were to analyze the accuracy of ECHO in determining infarction size in rats during the first days following coronary occlusion and to test whether

4. Use of a solid reagent in the triphenyl tetrazolium chloride test for bacteriuria
The use of a solid reagent in the triphenyl tetrazolium chloride (T.T.C.) test for significant bacteriuria is described. The reagent gave a positive result with 108 (86%) of 126 specimens of urine containing over 100,000 organisms per ml. In comparison with the standard T.T.C. test the modified test gave comparable results. Some possible reasons for the vary

5. Quantitative reduction of 2,3,4-triphenyl tetrazolium chloride by hamster trachea organ cultures: effects of Mycoplasma pneumoniae cells and membranes.
The ability of Mycoplasma pneumoniae cells and membranes to affect tetrazolium reduction by hamster trachea organ cultures was evaluated. Uninfected trachea explants reduced 2,3,5-triphenyl tetrazolium chloride (TTC) and nitro-blue tetrazolium when incubated at 37 C in the absence of air. Reduced tetrazolium salts (formazans) were extractable with acetone or

6. EFFECT OF DIHYDROSTREPTOMYCIN ON TETRAZOLIUM DYE REDUCTION IN ESCHERICHIA COLI
Bragg, P. D. (University of British Columbia, Vancouver, British Columbia, Canada) and W. J. Polglase. Effect of dihydrostreptomycin on tetrazolium dye reduction in Escherichia coli. J. Bacteriol. 85:795–800. 1963.—Sonic-disrupted extracts of Escherichia coli, grown without added antibiotic (sensitive and resistant), contained (in supernatant of fraction

7. DIHYDROSTREPTOMYCIN, VITAMIN K2-COUPLED TETRAZOLIUM REDUCTION, AND OXIDATIVE PHOSPHORYLATION IN ESCHERICHIA COLI
Bragg, P. D. (University of British Columbia, Vancouver, B.C., Canada). Dihydrostreptomycin, vitamin K2-coupled tetrazolium reduction, and oxidative phosphorylation in Escherichia coli. J. Bacteriol. 88:1019–1023. 1964.—Dihydrostreptomycin inhibited the vitamin K2-coupled pyruvate-triphenyltetrazolium (TTC) reductase system in extracts from antibiotic-se

8. Localized Tetrazolium Reduction in Relation to N2 Fixation, CO2 Fixation, and H2 Uptake in Aquatic Filamentous Cyanobacteria
The aquatic filamentous cyanobacteria Anabaena oscillarioides and Trichodesmium sp. reveal specific cellular regions of tetrazolium salt reduction. The effects of localized reduction of five tetrazolium salts on N2 fixation (acetylene reduction), 14CO2 fixation, and 3H2 utilization were examined. During short-term (within 30 min) exposures in A. oscillarioid

9. Improved Isolation and Differentiation of Enterococci in Cheese
Further documentation of an enterococcus selective differential (ESD) medium was obtained in isolations from eight different cheeses. An improved differentiation of tetrazolium salt (2, 3, 5-triphenyl tetrazolium hydrochloride [TTC])-reducing strains of Streptococcus faecalis from TTC-nonreducing or TTC-faintly-reducing Streptococcus faecium was attained. Th

10. Generalized indicator plate for genetic, metabolic, and taxonomic studies with microorganisms.
We have developed an indicator plate that works well for diverse types of substrates and microorganisms. The plates are inexpensive and easy to prepare. The essential components are agar, buffer, growth-supporting nutrients, a test substrate, and 2,3,5-triphenyl tetrazolium chloride (TTC). Using various strains of Salmonella typhimurium and Escherichia coli,

11. Estimation and Analysis of Cucumber (Cucumis sativus L.) Leaf Cellular Heat Sensitivity.
Triphenyl tetrazolium chloride (TTC) reduction by cucumber (Cucumis sativus L. cv Poinsett 76 and cv Ashley) leaf discs was used as a viability assay to examine the effect of temperature pretreatment on the tissue response to acute hyperthermia. Semi-logarithmic plots of TTC reduction as a function of incubation time at different temperatures from 40 to 60[d

12. Modification of the Cellular Heat Sensitivity of Cucumber by Growth under Supplemental Ultraviolet-B Radiation.
The effect of ultraviolet B (UV-B) radiation on the thermal sensitivity of cucumber (Cucumis sativus L.) was studied using UV-B-sensitive cv Poinsett 76 and UV-B-resistant cv Ashley grown under control and elevated (300 mW m-2) UV-B radiation levels. Using both cotyledon and leaf discs, the ability of the tissue to reduce triphenyl tetrazolium chloride (TTC)
