Findings from A. Renvoise and co-researchers advance knowledge in actinomycosis
2009 JUN 2 - (NewsRx.com) -- According to a study from Marseille, France, "Gram-positive, non-spore-forming rods (strain 4401292 T) were isolated from a human blood sample. Based on cellular morphology and the results of biochemical tests, this strain was tentatively identified as belonging to an undescribed species of the genus Actinomyces." "Phylogenetic analysis based on 16S rRNA gene sequence comparison showed that the bacterium was related closely to Actinomyces gerencseriae (95.1% 16S rRNA gene sequence similarity), Actinomyces israelii (95.2%), Actinomyces oricola (95.2%), Actinomyces ruminicola (93.3%) and Actinomyces dentalis (91.4%). The predominant fatty acids were C18:1 omega 9c and C16:0," wrote A. Renvoise and colleagues. The researchers concluded: "On the basis of phenotypic data and phylogenetic inference, the novel species Actinomyces massiliensis sp. nov. is proposed; the type strain is 4401292(T) (=CSUR P18(T) =CCUG 53522(T))." Renvoise and colleagues published their study in International Journal of Systematic and Evolutionary Microbiology (Actinomyces massiliensis sp nov., isolated from a patient blood culture. International Journal of Systematic and Evolutionary Microbiology, 2009;59(Part 3):540-544). For more information, contact V.
