Microorganisms are spectacularly diverse phylogenetically, but available estimates of their species richness are vague and problematic. For example, for comparable environments, the estimated numbers of species range from a few dozen or hundreds to tens of thousands and even half a million. Such estimates provide no baseline information on either local or(More)
The soil bacterial community and some inoculated bacteria were monitored to assess the microbial responses to prescribed fire in their microcosm. An acridine orange direct count of the bacteria in the unburned control soil were maintained at a relatively stable level (2.0 approximately 2.7 x 10(9) cells/g(-1).soil) during the 180 day study period. The(More)
For the evaluation of efficacy of cardiopulmonary exercise testing, we compared New York Heart Association functional class with peak oxygen consumption rate (VO(2)peak) in 31 patients with severe mitral regurgitation who underwent mitral valve repair surgery. One year later, the VO(2)peak values did not show significant improvement; however, the patients(More)
Contrary to the generally held notions about microbial survival, the recently published paper by Johnson et al., 'Ancient bacteria show evidence of DNA repair', presents evidence suggesting that non-spore-forming bacteria in ancient samples are apparently alive, as judged by intact DNA, and fare better than spores. The data presented in this work raise(More)
Archaea have been found in many more diverse habitats than previously believed due in part to modern molecular approaches to discovering microbial diversity. We report here an unexpected expansion of the habitat diversity of the Archaea in the Cariaco Basin we found using a primer set designed for 18S eukaryotic rDNA sequence analysis. The results presented(More)
In August 2013, blossom blight and wet rot were observed on flowers of Abelmoschus manihot in a private garden in Hongcheon County, Korea. The fungus initially infected fading flower petals, then expanded to encompass entire flowers and finally resulted in flower desiccation and fall. The causal fungus was identified by morphological characterization and(More)
Leaf spot was observed on garden phlox (Phlox paniculata) in Yesan, Korea, in 2008. Based on the morphological characteristics of the fungus and the host genus, the isolate was identified as Septoria phlogis. Internal transcribed spacer sequences of rDNA of the isolate confirmed its close affinity to previously known species of Septoria. In 2010 and 2011,(More)
