TL;DR: Three novel real-time PCR assays designed for the detection of specific sequence regions of the lytA, ply, and psaA genes were developed and should be considered the assays of choice for the Detection of pneumococcal DNA, particularly when upper respiratory P-LVS might be present in the clinical specimen.
Journal ArticleDOI
Classification of the Legionnaires' Disease Bacterium: Legionella pneumophila, genus novum, species nova, of the Family Legionellaceae, familia nova
TL;DR: DNA comparisons showed that all strains of the Legionnaires' disease bacterium were members of the same species, and it is proposed that the LD bacterium be named Legionella pneumophila species nova, the type species of Legionella, genus novum.
Journal ArticleDOI
Proposals to unify the genera Bartonella and Rochalimaea, with descriptions of Bartonella quintana comb. nov., Bartonella vinsonii comb. nov., Bartonella henselae comb. nov., and Bartonella elizabethae comb. nov., and to remove the family Bartonellaceae from the order Rickettsiales.
TL;DR: On the basis of DNA relatedness data, previous 16S rRNA sequence data, guanine-plus-cytosine contents, and phenotypic characteristics, neither Bartonella bacilliformis nor Rochalimaea species are closely related to other organisms currently classified in the order Rickettsiales.
Rochalimaea henselae sp.nov., aCauseofSepticemia, Bacillary Angiomatosis, andParenchymal Bacillary Peliosis
TL;DR: Rochalimaea henselae sp.nov. as mentioned in this paper is a newly recognized member of the Rickettsiaceae, which is a pathogen that maybeencountered inimmunocompromised orimmuno-competent patients.
