Objective: To explore the phytochemical and antimicrobial activities as well as the insecticidal properties of the different sections of Ricinus communis (castor) plant in Mauritius. Methods: Qualitative and quantitative methods were used for the determination of phytochemicals in the crude leaves, pericarp, seeds, bark and root extracts obtained by using polar and non-polar solvents. The disc ...
OBJECTIVES By adapting an antibiotic-susceptible Staphylococcus aureus strain to increasing concentrations of ethidium bromide, a known substrate of efflux pumps (EPs), and by phenotypically and genotypically analysing the resulting progeny, we characterized the molecular mechanisms of S. aureus adaptation to ethidium bromide. METHODS S. aureus ATCC 25923 was grown in increasing concentration...
Twenty mollicute strains isolated primarily from insect hosts were characterized and arranged into eight new species in the genus Mesoplasma. Morphological examination of the organisms by electron and dark-field microscopic techniques revealed that the cells of each strain were small, nonhelical, nonmotile, pleomorphic, and coccoid and that each cell was surrounded by a single cytoplasmic membr...
Strains of aerobic, microaerobic, nonsymbiotic, and symbiotic dinitrogen-fixing bacteria were screened for the presence of alternative nitrogenase (N2ase) genes by DNA hybridization between genomic DNA and DNA encoding structural genes for components 1 of three different enzymes. A nifDK gene probe was used as a control to test for the presence of the commonly occurring Mo-Fe N2ase, a vnfDGK ge...
We examined the effectiveness of antisense RNA (as RNA) strategies for metabolic engineering of Clostridium acetobutylicum. Strain ATCC 824(pRD4) was developed to produce a 102-nucleotide asRNA with 87% complementarity to the butyrate kinase (BK) gene. Strain ATCC 824(pRD4) exhibited 85 to 90% lower BK and acetate kinase specific activities than the control strain. Strain ATCC 824(pRD4) also ex...
Copper complexes of [Cu(phen)(tda)].2H2O(1) and [(phen)2Cu(µ-tda) Cu(phen)](ClO4)2.1.5H2O (2) (where phen is 1,10-phenanthroline and tda2- is thiodiacetate) have been synthesized. Both complexes were characterized by elemental analysis, IR, UV–Vis spectroscopy and cyclic voltammetry. Their solid state struct...
BACKGROUND Porphyromonas gulae are black-pigmented anaerobic bacteria isolated from the gingival sulcus of various animal hosts and are distinct from Porphyromonas gingivalis originating in humans. We previously reported the antigenic similarities of 41-kDa fimbriae between P. gulae ATCC 51700 and P. gingivalis ATCC 33277. In this study, to clarify the presence of another type of fimbriae of P....
Streptococcus gallolyticus infections in humans are often associated with bacteremia, infective endocarditis and colon cancers. The disease manifestations are different depending on the subspecies of S. gallolyticus causing the infection. Here, we present the complete genomes of S. gallolyticus ATCC 43143 (biotype I) and S. pasteurianus ATCC 43144 (biotype II.2). The genomic differences between...
Blastoschizomyces capitatus was cultured from the nail of a healthy patient with onychomycosis. The identity of the isolate was initially established by standard methods and ultrastructural analysis and was verified by molecular probing. Strains ATCC 200929, ATCC 62963, and ATCC 62964 served as reference strains for these analyses. To our knowledge, this is the first case of nail infection seco...
The telavancin broth microdilution susceptibility testing method was revised, which provides MIC results lower than those obtained by the previous method. This study was performed to reestablish the quality control ranges for telavancin when tested against the strains (updated MIC range) Staphylococcus aureus ATCC 29213 (0.03 to 0.12 μg/ml), Enterococcus faecalis ATCC 29212 (0.03 to 0.12 μg/ml)...
