| infections due to actinomyces neuii (former "cdc coryneform group 1" bacteria). | sixty-seven patients with infections in which the recently proposed species actinomyces neuii was involved were observed during a 4 1/2-year period. microbiological as well as clinical features of the patients are presented. a. neuii does not cause typical actinomycosis and is detected most often in material from abscesses or infected atheromas. one case of a fatal septicemia caused by a. neuii in a non-immunocompromised host was seen. antimicrobial susceptibility patterns of a. neuii isolates a ... | 1995 | 7622266 |
| assignment of human-derived cdc group 1 coryneform bacteria and cdc group 1-like coryneform bacteria to the genus actinomyces as actinomyces neuii subsp. neuii sp. nov., subsp. nov., and actinomyces neuii subsp. anitratus subsp. nov. | almost the entire 16s rrna gene sequences of some strains of cdc group 1 and group 1-like coryneform bacteria, isolated from human sources, were determined. comparative analysis of the rrna sequence data revealed that both groups of coryneforms belong to the genus actinomyces. on the basis of the present molecular findings and previous biochemical studies, we propose a new actinomyces species, actinomyces neuii sp. nov., containing actinomyces neuii subsp. neuii subsp. nov. for cdc group 1 coryn ... | 1994 | 8123558 |
| catalase-negative actinomyces neuii subsp. neuii isolated from an infected mammary prosthesis. | in this case report a catalase-negative strain of actinomyces neuii subsp. neuii is described as the possible causative agent of an infected mammary prosthesis. dna hybridization studies and 16s rrna analysis confirmed that the strain belongs to the species actinomyces neuii subsp. neuii. since this strain is the first a. neuii subsp. neuii strain reported to be catalase negative, the catalase reaction should no longer be considered a key reaction for the diagnosis of this species but must be in ... | 2000 | 10959731 |

| transfer of members of the genus falcivibrio to the genus mobiluncus, and emended description of the genus mobiluncus. | it has long been thought that the genera mobiluncus and falcivibrio contain the same organisms. using a polyphasic approach, it was found that mobiluncus curtisii and mobiluncus mulieris were the same as falcivibrio vaginalis and falcivibrio grandis, respectively. as the genus name mobiluncus takes precedence, it is proposed that f. vaginalis and f. grandis be transferred to the genus mobiluncus. in agreement with previous studies, results from phenotypic tests did not support the separation of ... | 2004 | 15053324 |
