| bacteremias caused by selenomonas artemidis and selenomonas infelix. | we report two different cases of bacteremia caused by two recently described selenomonas species, selenomonas artemidis and selenomonas infelix. both species are normally found in human buccal flora. s. artemidis bacteremia appeared in a patient (number 1) who presented with an air-fluid pulmonary cavity and clinical conditions consistent with an anaerobic lung abscess. while the patient improved with antibiotic therapy, cultures of respiratory secretions yielded mycobacterium tuberculosis. this ... | 1990 | 2405009 |
| coverage theories for metagenomic dna sequencing based on a generalization of stevens' theorem. | metagenomic project design has relied variously upon speculation, semi-empirical and ad hoc heuristic models, and elementary extensions of single-sample lander-waterman expectation theory, all of which are demonstrably inadequate. here, we propose an approach based upon a generalization of stevens' theorem for randomly covering a domain. we extend this result to account for the presence of multiple species, from which are derived useful probabilities for fully recovering a particular target micr ... | 2013 | 22965653 |
| identification of selenomonas species by whole-genomic dna probes, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, biochemical tests and cellular fatty acid analysis. | nonisotopic, whole-genomic dna probes, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (sds-page), biochemical tests in microtiter trays and cellular fatty acid (cfa) analysis were compared for the identification of 5 oral selenomonas species. dna probes were prepared by biotin-labeling dna extracted from the type strains of selenomonas noxia, selenomonas flueggei, selenomonas artemidis, selenomonas infelix and selenomonas sputigena. the probes were hybridized with dna from 21 referenc ... | 1992 | 1528628 |
| the inhibitory action of fatty acids on oral bacteria. | saturated and unsaturated fatty acids and fatty acid derivatives were examined for their growth-inhibitory effects towards three selected oral bacteria: porphyromonas gingivalis, selenomonas artemidis, and streptococcus sobrinus. of the 45 compounds surveyed, only one, myristoleic acid, was inhibitory towards s. artemidis at a concentration < 100 micrograms/ml. cis-hexadecenoic and cis-octadecenoic acids were generally inhibitory towards p. gingivalis and s. sobrinus, but there was no correlatio ... | 1996 | 9028262 |
| the action of thymol on oral bacteria. | several effects of thymol, a plant-derived antimicrobial agent, on porphyromonas gingivalis, selenomonas artemidis and streptococcus sobrinus were examined. the extremely rapid efflux of intracellular constituents evoked by thymol is consistent with its postulated membranotropic effects. correlations between leakage-inducing concentrations of thymol and minimal inhibitory concentrations and minimal bactericidal concentrations suggest that membrane perforation is a principal mode of action of thi ... | 1995 | 8602337 |
