| bacterial diversity in a nonsaline alkaline environment: heterotrophic aerobic populations. | heterotrophic populations were isolated and characterized from an alkaline groundwater environment generated by active serpentinization, which results in a ca(oh)2-enriched, extremely diluted groundwater with ph 11.4. one hundred eighty-five strains were isolated in different media at different ph values during two sampling periods. to assess the degree of diversity present in the environment and to select representative strains for further characterization of the populations, we screened the is ... | 2004 | 15574939 |
| evaluation of bacterial nitrate reduction in the human oral cavity. | it is hypothesized that the enterosalivary nitrate circulation encourages nitrate reducing bacteria to reside within the oral cavity. nitrite production may then limit the growth of acidogenic bacteria as a result of the production of antimicrobial oxides of nitrogen, including nitric oxide. this study was carried out with 10 subjects to characterize oral nitrate reduction and identify the bacteria responsible. nitrate reduction varied between individuals (mean 85.4 +/- 15.9 nmol nitrite min(-1) ... | 2005 | 15693824 |

| stomatococcus mucilaginosus meningitis in a healthy 2-month-old child. | stomatococcus mucilaginosus is a gram-positive, catalase-variable organism considered part of the normal human oral and upper respiratory tract flora. although traditionally believed to be an organism of low virulence, stomatococcus mucilaginosus has been reported to be an opportunistic pathogen in immunocompromised patients. we describe what we believe is the first reported case of stomatococcus mucilaginosus meningitis in a healthy child. the isolate was multidrug-resistant, susceptible only t ... | 2008 | 18287304 |
| mlpa diagnostics of complex microbial communities: relative quantification of bacterial species in oral biofilms. | a multitude of molecular methods are currently used for identification and characterization of oral biofilms or for community profiling. however, multiplex pcr techniques that are able to routinely identify several species in a single assay are not available. multiplex ligation-dependent probe amplification (mlpa) identifies up to 45 unique fragments in a single tube pcr. here we report a novel use of mlpa in the relative quantification of targeted microorganisms in a community of oral microbiot ... | 2008 | 18824042 |
