| proposals to unify the genera grahamella and bartonella, with descriptions of bartonella talpae comb. nov., bartonella peromysci comb. nov., and three new species, bartonella grahamii sp. nov., bartonella taylorii sp. nov., and bartonella doshiae sp. nov. | polyphasic methods were used to examine the taxonomic positions of three newly identified grahamella species. a comparison of the 16s rrna gene sequences of these organisms with the sequences available for other bacteria revealed that these three species form a tight monophyletic cluster with members of the genus bartonella. this cluster is only remotely related to other members of the order rickettsiales. determinations of the levels of dna relatedness between grahamella species and bartonella ... | 1995 | 7857789 |
| a bacteriophage-like particle from bartonella bacilliformis. | bartonella bacilliformis and bartonella henselae, the respective agents of oroya fever and cat-scratch disease in humans, are known to produce bacteriophage-like particles (blps) that package 14 kbp segments of the host chromosome. data from this study suggest that other bartonella species including bartonella quintana, bartonella doshiae and bartonella grahamii also contain similar blps, as evidenced by the presence of a 14 kbp extrachromosomal dna element in their genomes, whereas bartonella e ... | 2000 | 10746763 |
| phylogenetic classification of bartonella species by comparing groel sequences. | bartonella is a bacterial genus classified in the alpha-proteobacteria on the basis of 165 rdna sequence comparison. the highly conserved heat-shock chaperonin protein, groel, has proved to be a valuable resolving tool to classify ten bartonella species. the groel gene was amplified and sequenced from ten bartonella isolates: bartonella alsatica, bartonella vinsonii subsp. arupensis, bartonella taylorii, bartonella tribocorum, bartonella birtlesii, bartonella henselae marseille (urlly8), b. hens ... | 2002 | 11837299 |
| molecular detection of bartonella species infecting rodents in slovenia. | rodents, collected in three zoogeographical regions across slovenia, were tested for the presence of bartonellae using direct pcr-based amplification of 16s/23s rrna gene intergenic spacer region (its) fragments from splenic dna extracts. bartonella dna was detected in four species of rodents, apodemus flavicollis, apodemus sylvaticus, apodemus agrarius and clethrionomys glareolus, in all three zoogeographic regions at an overall prevalence of 40.4%. the prevalence of infection varied significan ... | 2007 | 17374132 |
| to be or not to be associated: power study of four statistical modeling approaches to identify parasite associations in cross-sectional studies. | a growing number of studies are reporting simultaneous infections by parasites in many different hosts. the detection of whether these parasites are significantly associated is important in medicine and epidemiology. numerous approaches to detect associations are available, but only a few provide statistical tests. furthermore, they generally test for an overall detection of association and do not identify which parasite is associated with which other one. here, we developed a new approach, the ... | 2014 | 24860791 |
| zoonotic pathogens in atlantic forest wild rodents in brazil: bartonella and coxiella infections. | zoonotic pathogens comprise a significant and increasing fraction of all emerging and re-emerging infectious diseases that plague humans. identifying host species is one of the keys to controlling emerging infectious diseases. from march 2007 until april 2012, we collected a total of 131 wild rodents in eight municipalities of rio de janeiro, brazil. we investigated these rodents for infection with coxiella burnetii, bartonella spp. and rickettsia spp. in total, 22.1% (29/131) of the rodents wer ... | 2017 | 28077317 |
