| 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 |
| 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 |
| flea-borne bartonella grahamii and bartonella taylorii in bank voles. | bartonella species are increasingly associated with a range of human and animal diseases. despite this, we have a poor understanding of the ecology and epidemiology of many species, especially those circulating in wild populations. previous studies have demonstrated that a diverse range of bartonella species are abundant in wild rodent populations; little is known regarding their modes of transmission, although both direct and indirect routes have been suggested. in this study, with bank voles ( ... | 2004 | 15200860 |
| disruption of a host-parasite system following the introduction of an exotic host species. | the potential of biological invasions to threaten native ecosystems is well recognized. here we describe how an introduced species impacts on native host-parasite dynamics by acting as an alternative host. by sampling sites across an invasion front in ireland, we quantified the influence of the introduced bank vole (clethrionomys glareolus) on the epidemiology of infections caused by flea-transmitted haemoparasites of the genus bartonella in native wood mice (apodemus sylvaticus). bartonella inf ... | 2005 | 15977903 |
| 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 |
| an immunocompromised murine model of chronic bartonella infection. | bartonella are ubiquitous gram-negative pathogens that cause chronic blood stream infections in mammals. two species most often responsible for human infection, b. henselae and b. quintana, cause prolonged febrile illness in immunocompetent hosts, known as cat scratch disease and trench fever, respectively. fascinatingly, in immunocompromised hosts, these organisms also induce new blood vessel formation leading to the formation of angioproliferative tumors, a disease process named bacillary angi ... | 2010 | 20395436 |
| variability of bartonella genotypes among small mammals in spain. | in order to study which bartonella genotypes are circulating among small mammals in spain, we analyzed the spleens of 395 animals from three different areas-247 animals from the basque country (northern spain), 121 animals from catalonia (northeastern spain), and 27 animals from madrid (central spain)-by a triplex pcr combined with a reverse line blot previously described by our group. the prevalence of bartonella was 26.8% (106/395), and in 4.8% (19/395) of the animals more than one bartonella ... | 2010 | 20935117 |
| bartonella, rodents, fleas and ticks: a molecular field study on host-vector-pathogen associations in saxony, eastern germany. | bartonellae cause zoonotic diseases and are transmitted by arthropods. rodents are reservoirs for most bartonella spp. as the knowledge about bartonella in rodents and their parasitizing ectoparasites is scarce in germany, this study's objectives were to investigate bartonella spp. in small mammals and in their ectoparasites. a total of 79 small mammals (seven species) were captured and their ectoparasites collected at seven sites around leipzig, saxony, germany, in 2010 and 2011. altogether, 79 ... | 2016 | 27220973 |
| prevalence and diversity of bartonella species in wild small mammals in asia. | we collected 641 small mammals belonging to 17 species of rodentia and four species of soricomorpha in japan, korea, russia, taiwan, and thailand and investigated the prevalence and genetic diversity of bartonella species. apodemus (field mice) and rattus (rats) were the most-common genera captured, making up 56.0% and 23.1% of the total specimens, respectively. bartonellae were isolated from 54.6% of the collected animals, and the prevalence varied depending on the host species and the country ... | 2016 | 26528573 |
| bartonella infection in small mammals and their ectoparasites in lithuania. | the bartonella pathogen is an emerging zoonotic agent. epidemiological studies worldwide have demonstrated that small mammals are reservoir hosts of bartonella spp. and their ectoparasites are potential vectors. the aim of this study was to investigate the prevalence of bartonella infections in small mammals (rodentia, insectivora) and their ectoparasites (fleas and ticks) in lithuania. a total of 430 small mammals representing nine species were captured with live-traps in lithuania during 2013- ... | 2016 | 26344603 |
| bacteria of the genus roseobacter associated with the toxic dinoflagellate prorocentrum lima. | the dinoflagellate prorocentrum lima is known to produce diarrhetic shellfish poisons. however, it is yet unclear if the dinoflagellates themselves or the bacteria associated with them produce the toxins. here we analyze the toxicity as well as the spectrum of bacteria in two cultures of p. lima, namely p. lima-sy and p. lima-st, which initially derived from the same p. lima strain pl2v. toxicity tests, applying the artemia bioassay revealed in both cultures high levels of toxins. the bacteria, ... | 1998 | 23194717 |
