| molecular method for bartonella species identification in clinical and environmental samples. | a new, efficient molecular method for detection of bartonella, based on the 16s-23s rrna intergenic spacer and 16s rrna amplification by multiplex pcr combined with reverse line blotting, was designed. this assay could simultaneously detect 20 different known species and other bartonella species not described previously. | 2008 | 18094134 |
| diversifying selection and concerted evolution of a type iv secretion system in bartonella. | we have studied the evolution of a type iv secretion system (t4ss), in bartonella, which is thought to have changed function from conjugation to erythrocyte adherence following a recent horizontal gene transfer event. the system, called trw, is unique among t4sss in that genes encoding both exo- and intracellular components are located within the same duplicated fragment. this provides an opportunity to study the influence of selection on proteins involved in host-pathogen interactions. we seque ... | 2008 | 18065487 |
| pcr for bacterial 16s ribosomal dna in multiple sclerosis cerebrospinal fluid. | the cause of multiple sclerosis (ms) is currently unknown. the hypothesis of this study is that ms is caused by a chronic bacterial infection of the central nervous system (cns) and the ensuing immune response. we developed a sensitive two-stage polymerase chain reaction method using nested or semi-nested primers specific for the bacterial 16s ribosomal dna to test for the presence of bacterial dna in cerebrospinal fluid. we designed seven sets of primers to amplify dna from spirochetes , campyl ... | 2008 | 17986505 |
| a sacb mutagenesis strategy reveals that the bartonella quintana variably expressed outer membrane proteins are required for bloodstream infection of the host. | bartonella bacteria adhere to erythrocytes and persistently infect the mammalian bloodstream. we previously identified four highly conserved bartonella quintana adhesin genes that undergo phase variation during prolonged bloodstream infection. the variably expressed outer membrane proteins (vomp) encoded by these genes are members of the trimeric autotransporter adhesin family. each b. quintana vomp appears to contribute a different adhesion phenotype, likely mediated by the major variable regio ... | 2008 | 18070893 |
| bartonella tamiae sp. nov., a newly recognized pathogen isolated from three human patients from thailand. | three strains of a novel bartonella species (bartonella tamiae) were isolated from human patients from thailand. sequence analysis of six chromosomal regions (16s rrna, glta, groel, ftsz, rpob, and the intergenic spacer region) and phenotypical analysis supported the similarity of the three strains and placed them within the genus bartonella separately from previously described species. | 2008 | 18077632 |
