| actinomyces nasicola sp. nov., isolated from a human nose. | a previously undescribed facultatively anaerobic, catalase-negative, actinomyces-like bacterium was isolated from the nose of a human. on the basis of its cellular morphology and the results of biochemical testing, the micro-organism was tentatively identified as a member of the genus actinomyces, but it did not correspond to any currently recognized species. comparative 16s rrna gene sequencing studies showed the bacterium to be a hitherto unknown subline within the genus actinomyces, displayin ... | 2003 | 13130031 |
