| bartonella tribocorum sp. nov., a new bartonella species isolated from the blood of wild rats. | two bartonella strains from blood of two wild rats (rattus norvegicus) living in a rural environment were isolated. these strains were distinct from all previously known bartonella species based on phenotypic and genotypic characteristics. this new species is distinguished by its trypsin-like activity, the absence of the ability to hydrolyse proline and tributyrin, its 16s rrna and citrate synthase gene sequences and by whole-dna hybridization data. this new species, for which the name bartonell ... | 1998 | 9828434 |
| rats of the genus rattus are reservoir hosts for pathogenic bartonella species: an old world origin for a new world disease? | bartonella species were isolated from the blood of 63 of 325 rattus norvegicus and 11 of 92 rattus rattus from 13 sites in the united states and portugal. infection in both rattus species ranged from 0% (e.g., 0/87) to approximately 60% (e.g., 35/62). a 337-bp fragment of the citrate synthase (glta) gene amplified by polymerase chain reaction was sequenced from all 74 isolates. isolates from r. norvegicus were most similar to bartonella elizabethae, isolated previously from a patient with endoca ... | 1999 | 10353885 |
| genetic and ecologic characteristics of bartonella communities in rodents in southern china. | ecologic and bacteriologic observations of small mammals captured in yunnan province in the people's republic of china indicated that bartonella infections occurred at a high prevalence among some rodent species. sequence analyses of the citrate synthase genes of these bartonella demonstrated that rodents in this region harbored a diverse assemblage of strains. the bartonella isolates obtained from apodemus, eothenomys, and rattus typically clustered separately by genus of rodent host. cultures ... | 2002 | 12201602 |
| prevalence study of antibody to ratborne pathogens and other agents among patients using a free clinic in downtown los angeles. | norway rats (rattus norvegicus) are hosts for various microbes. homeless people who have contact with rats may be at risk of infection by them. the los angeles county department of health services initiated a seroepidemiologic study among patients who used a free clinic in downtown los angeles; 200 serum specimens obtained for other routine assays were tested for antibodies to ratborne pathogens and other agents. the seroprevalence of antibody to hepatitis e virus in this population was 13.6%; t ... | 2002 | 12447746 |
| urban zoonoses caused by bartonella, coxiella, ehrlichia, and rickettsia species. | the last half of the 20th century witnessed an increase in the occurrence and recognition of urban zoonoses caused by members of the genera bartonella, coxiella, ehrlichia, and rickettsia, all traditionally considered to be members of the family rickettsiaceae. in recent years, new human pathogens (bartonella elizabethae, bartonella henselae, and rickettsia felis) have been recognized in urban environments. other newly recognized pathogens (ehrlichia chaffeensis and ehrlichia phagocytophila in t ... | 2001 | 12653141 |
| a survey of zoonotic pathogens carried by norway rats in baltimore, maryland, usa. | norway rats (rattus norvegicus) carry several zoonotic pathogens and because rats and humans live in close proximity in urban environments, there exists potential for transmission. to identify zoonotic agents carried by rats in baltimore, maryland, usa, we live-trapped 201 rats during 2005-2006 and screened them for a panel of viruses, bacteria, and parasites. antibodies against seoul virus (57.7%), hepatitis e virus (hev, 73.5%), leptospira interrogans (65.3%), bartonella elizabethae (34.1%), a ... | 2007 | 17224086 |
| bartonella strains in small mammals from dhaka, bangladesh, related to bartonella in america and europe. | ecological and bacteriologic observations of small mammals captured in dhaka, bangladesh, indicated that bartonella infections occurred in high prevalence among lesser bandicoot rats (bandicota bengalensis), black rats (rattus rattus), and house shrews (suncus murinus). sequence analysis of the citrate synthase gene of bartonella isolates showed that small mammals in bangladesh harbored a diverse assemblage of strains. some cultures were genetically related to bartonella elizabethae, a species i ... | 2007 | 17827381 |
| epidemiology of bartonella infection in rodents and shrews in taiwan. | during the period of august 2002 and november 2004, an epidemiological investigation for bartonella infection was conducted in small mammals in taiwan. using whole blood culture on chocolate agar plates, bartonella species were successfully isolated from 41.3% of the 310 animals tested. the isolation rate of bartonella species varied among different animal species, including 52.7% of the 169 rattus norvegicus, 28.6% of the 126 sucus murinus, 10% of the 10 rattus rattus and 66.7% of the three rat ... | 2010 | 19538457 |
| a multi-gene analysis of diversity of bartonella detected in fleas from algeria. | we report the molecular detection of several bartonella species in 44 (21.5%) of 204 fleas from algeria collected from 26 rodents and 7 hedgehogs. bartonella elizabethae and b. clarridgeiae were detected in the fleas collected on hedgehogs. bartonella tribocorum and b. elizabethae were detected in fleas collected from rats and mice, and sequences similar to an unnamed bartonella sp. detected in rodents from china were detected in rats as well as a genotype of bartonella closely related to barton ... | 2011 | 22153359 |
| preliminary survey of ectoparasites and associated pathogens from norway rats in new york city. | the norway rat (rattus norvegicus) is a reservoir of many zoonotic pathogens and lives in close proximity to humans in urban environments. human infection with rodent-borne disease occurs either directly through contact with a rat or its excreta, or indirectly via arthropod vectors such as fleas and ticks. here, we report on the diversity and abundance of ectoparasitic arthropod species and associated pathogenic bacteria from 133 norway rats trapped over a 10-mo period in manhattan, new york, ny ... | 2015 | 26336309 |
| high prevalence of rickettsia typhi and bartonella species in rats and fleas, kisangani, democratic republic of the congo. | the prevalence and identity of rickettsia and bartonella in urban rat and flea populations were evaluated in kisangani, democratic republic of the congo (drc) by molecular tools. an overall prevalence of 17% bartonella species and 13% rickettsia typhi, the agent of murine typhus, was found in the cosmopolitan rat species, rattus rattus and rattus norvegicus that were infested by a majority of xenopsylla cheopis fleas. bartonella queenslandensis, bartonella elizabethae, and three bartonella genot ... | 2014 | 24445202 |
| isolation of bartonella species from rodents in taiwan including a strain closely related to 'bartonella rochalimae' from rattus norvegicus. | an increasing number of bartonella species originally isolated from small mammals have been identified as emerging human pathogens. during an investigation of bartonella infection in rodent populations carried out in taiwan in 2006, a total of 58 rodents were tested. it was determined that 10.3 % (6/58) of the animals were bartonella bacteraemic. after pcr/rflp analysis, four isolates were identified as bartonella elizabethae and one isolate as bartonella tribocorum. however, there was one speci ... | 2008 | 19018019 |
