A Gram-reaction-positive, motile, coccus-shaped actinobacterium, designated strain T2A-S27T, was isolated from a roof tile in Oporto (Portugal) and studied using a polyphasic approach. The 16S rRNA gene sequence of the novel isolate showed high similarity to that of Kineococcus marinus KST3-3T (97.8 % sequence similarity). Strain T2A-S27T showed lower 16S rRNA gene sequence similarities with other members of the genus Kineococcus and members of the family Kineosporiaceae (<94 %). A phylogenetic tree, based on 16S rRNA gene sequences, showed that strain T2A-S27T formed a coherent clade with the type strain of K. marinus and Quadrisphaera granulorum. The isolate was characterized by the presence of meso-diaminopimelic acid in the cell-wall peptidoglycan, MK-9(H2) as the predominant menaquinone and a polar lipid profile consisting of diphosphatidylglycerol and phosphatidylglycerol. The fatty acid profile was dominated by anteiso-C15 : 0. The DNA G+C content was 76.9 mol%. The low level of DNA–DNA relatedness to K. marinus (46–47 %) and the results of the chemotaxonomic and physiological studies clearly distinguished strain T2A-S27T from recognized species of the genus Kineococcus. On the basis of its phylogenetic position and phenotypic traits, strain T2A-S27T ( = LMG 24148T = CECT 7306T = DSM 23768T) represents a novel species of a new genus in the family Kineosporiaceae, for which the name Pseudokineococcus lusitanus gen. nov., sp. nov. is proposed. The misclassified species K. marinus is transferred to the new genus as Pseudokineococcus marinus comb. nov. The type strain of Pseudokineococcus marinus is KST3-3T ( = KCCM 42250T = NRRL B-24439T).
The holy water fonts from the churches of Seville, Spain have a strong bacterial contamination. Coliforms, Enterobacteriaceae and other pathogenic bacteria are widely represented in the fonts investigated. Thirty out of the 37 different species isolated from holy waters are known human pathogens. The high bacterial contamination is related to human skin transmission and, probably, to misuse of the water.
The taxonomic position of Agromyces fucosus subsp. hippuratus is revised on the basis of molecular and phenotypic data. Phylogenetic analysis based on 16S rRNA gene sequences, DNA–DNA relatedness values and differences from other species in phenotypic traits revealed in this and earlier studies suggested reclassification of A. fucosus subsp. hippuratus as a separate species, Agromyces hippuratus sp. nov., comb. nov. The type strain is VKM Ac-1352T (=JCM 9087T). An emended description of Agromyces fucosus is given.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
