| bartonella strains from ground squirrels are identical to bartonella washoensis isolated from a human patient. | the most likely animal source of a human case of cardiac disease in washoe county, nev., was identified by comparison of dna sequences of three genes (citrate synthase glta, 60-kda heat shock protein gene groel, and 16s rrna gene) of bartonella washoensis cultured from the human patient in question and of bartonella isolates obtained from the following nevada rodents: peromyscus maniculatus (17 isolates), tamias minimus (11 isolates), spermophilus lateralis (3 isolates), and spermophilus beechey ... | 2003 | 12574261 |
| isolation of bartonella washoensis from a dog with mitral valve endocarditis. | we report the first documented case of bartonella washoensis bacteremia in a dog with mitral valve endocarditis. b. washoensis was isolated in 1995 from a human patient with cardiac disease. the main reservoir species appears to be ground squirrels (spermophilus beecheyi) in the western united states. based on echocardiographic findings, a diagnosis of infective vegetative valvular mitral endocarditis was made in a spayed 12-year-old female doberman pinscher. a year prior to presentation, the re ... | 2003 | 14605197 |
| characterization of bartonella strains isolated from black-tailed prairie dogs (cynomys ludovicianus). | thirty bartonella strains were isolated from the blood of black-tailed prairie dogs (cynomys ludovicianus) from boulder county, colorado, usa. the bacteria appeared as small, fastidious, aerobic, gram-negative rods. the partial sequences of the citrate synthase gene (glta) demonstrated five unique genetic variants. phylogenetic analysis based on sequences of glta, 16s rrna, rpob, ftsz, and ribc showed that the black-tailed prairie dog-related bartonella variants comprise a distinct monophyletic ... | 2008 | 18237261 |
| meningitis due to a "bartonella washoensis"-like human pathogen. | we report the second human case of infection caused by an organism identified as the proposed bartonella species, "b. washoensis." the organism was isolated from a blood sample from a patient presenting with meningitis and early sepsis. oropsylla montana fleas were implicated as the vector for disease transmission in this case. | 2009 | 19439538 |
| multi-locus sequence analysis reveals host specific association between bartonella washoensis and squirrels. | to clarify phylogenetic relationships and genetic diversity among bartonella washoensis strains obtained from squirrels, multi-locus sequence analysis (mlsa) with the 16s rrna, ftsz, glta, groel, ribc, and rpob genes was applied for 20 strains of b. washoensis isolated from five genera of squirrels (tamias, tamiasciurus, glaucomys, sciurus, and spermophilus) within the family sciuridae. sequence similarities in the concatenated sequences of b. washoensis strains from squirrels of different gener ... | 2010 | 20884133 |
| enzymatic synthesis of bioinformatically predicted microcin c-like compounds encoded by diverse bacteria. | abstract the trojan horse escherichia coli antibiotic microcin c (mcc) consists of a heptapeptide attached to adenosine through a phosphoramidate linkage. mcc is synthesized by the mccb enzyme, which terminally adenylates the ribosomally synthesized heptapeptide precursor mcca. the peptide part is responsible for mcc uptake; it is degraded inside the cell to release a toxic nonhydrolyzable aspartyl-adenylate. bionformatic analysis reveals that diverse bacterial genomes encoding mccb homologues a ... | 2014 | 24803518 |
| molecular survey of bartonella species and yersinia pestis in rodent fleas (siphonaptera) from chihuahua, mexico. | rodent fleas from northwestern chihuahua, mexico, were analyzed for the presence of bartonella and yersinia pestis. in total, 760 fleas belonging to 10 species were tested with multiplex polymerase chain reaction analysis targeting the glta (338-bp) and pla genes (478-bp) of bartonella and y. pestis, respectively. although none was positive for y. pestis, 307 fleas were infected with bartonella spp., resulting in an overall prevalence of 40.4%. a logistic regression analysis indicated that the p ... | 2016 | 26576933 |
| distribution and diversity of bartonella washoensis strains in ground squirrels from california and their potential link to human cases. | we investigated the prevalence of bartonella washoensis in california ground squirrels (otospermophilus beecheyi) and their fleas from parks and campgrounds located in seven counties of california. ninety-seven of 140 (69.3%) ground squirrels were culture positive and the infection prevalence by location ranged from 25% to 100%. in fleas, 60 of 194 (30.9%) oropsylla montana were found to harbor bartonella spp. when screened using citrate synthase (glta) specific primers, whereas bartonella dna w ... | 2016 | 27705539 |
| bartonella spp. exposure in northern and southern sea otters in alaska and california. | since 2002, an increased number of northern sea otters (enhydra lutris kenyoni) from southcentral alaska have been reported to be dying due to endocarditis and/or septicemia with infection by streptococcus infantarius subsp. coli. bartonella spp. dna was also detected in northern sea otters as part of mortality investigations during this unusual mortality event (ume) in kachemak bay, alaska. to evaluate the extent of exposure to bartonella spp. in sea otters, sera collected from necropsied and l ... | 2014 | 25514118 |
| isolation and phylogenetic analysis of bartonella species from wild carnivores of the suborder caniformia in japan. | the prevalence of bartonella species was investigated among wild carnivores of the suborder caniformia, including 15 japanese badgers (meles anakuma), 8 japanese martens (martes melampus), 2 japanese weasels (mustela itatsi), 1 siberian weasel (mustela sibirica), 171 raccoon dogs (nyctereutes procyonoides), and 977 raccoons (procyon lotor) in japan. bartonella bacteria were isolated from one japanese badger (6.7%) and from one japanese marten (12.5%); however, no bartonella species was found in ... | 2012 | 22841404 |
