| delineation of a new species of the borrelia burgdorferi sensu lato complex, borrelia americana sp. nov. | analysis of borrelia isolates collected from ticks, birds, and rodents from the southeastern united states revealed the presence of well-established populations of borrelia burgdorferi sensu stricto, borrelia bissettii, borrelia carolinensis, and borrelia sp. nov. multilocus sequence analysis of five genomic loci from seven samples representing borrelia sp. nov. isolated from nymphal ixodes minor collected in south carolina showed their close relatedness to california strains known as genomospec ... | 2009 | 19846628 |
| the expanding lyme borrelia complex--clinical significance of genomic species? | ten years after the discovery of spirochaetes as agents of lyme disease in 1982 in the usa, three genomic species had diverged from the phenotypically heterogeneous strains of borrelia burgdorferi isolated in north america and europe: borrelia afzelii, b. burgdorferi sensu stricto (further b. burgdorferi), and borrelia garinii. whereas b. burgdorferi remained the only human pathogen in north america, all three species are aetiological agents of lyme borreliosis in europe. another seven genospeci ... | 2011 | 21414082 |
| molecular epidemiological surveillance to assess emergence and re-emergence of tick-borne infections in tick samples from china evaluated by nested pcrs. | an investigation was performed to detect eight pathogens in ticks collected from grass tips or animals in the southern, central and northeast regions of china. dna samples extracted from ticks were collected from ten different locations in eight provinces of china and subjected to screening for tick-borne pathogens, including borrelia burgdorferi sensu lato, ehrlichia spp., rickettsia spp., babesia/theileria spp., ehrlichia ruminantium, coxiella burnetii, and francisella tularensis, using nested ... | 2016 | 26943995 |
| detection of borrelia genomospecies 2 in ixodes spinipalpis ticks collected from a rabbit in canada. | lyme disease is a serious health problem, with many patients requiring in-depth clinical assessment and extended treatment. in the present study, we provide the first records of the western blacklegged tick, ixodes pacificus , and ixodes spinipalpis parasitizing eastern cottontails, sylvilagus floridanus . we also documented a triple co-infestation of 3 tick species (ixodes angustus, i. pacificus , i. spinipalpis) feeding on an eastern cottontail. notably, we discovered a unique member of the ly ... | 2017 | 27835071 |
| borrelia infection in ixodes pararicinus ticks (acari: ixodidae) from northwestern argentina. | the aim of this work was to describe for the first time the presence of borrelia burgdorferi sensu lato infecting ticks in argentina. unfed specimens of ixodes pararicinus collected from vegetation in jujuy province were tested for borrelia infection by pcr targeting the gene flagellin (fla), the rrfa-rrlb intergenic spacer region (igs) and the 16s rdna (rrs) gene. one male and one female of i. pararicinus collected in jujuy were found to be positive to borrelia infection with the three molecula ... | 2014 | 24979685 |
| geographical and genospecies distribution of borrelia burgdorferi sensu lato dna detected in humans in the usa. | the present study investigated the cause of illness in human patients primarily in the southern usa with suspected lyme disease based on erythema migrans-like skin lesions and/or symptoms consistent with early localized or late disseminated lyme borreliosis. the study also included some patients from other states throughout the usa. several pcr assays specific for either members of the genus borrelia or only for lyme group borrelia spp. (borrelia burgdorferi sensu lato), and dna sequence analysi ... | 2014 | 24568883 |
| eco-epidemiological factors contributing to the low risk of human exposure to ixodid tick-borne borreliae in southern california, usa. | little is known about the eco-epidemiology of lyme disease in southern california, a region where the incidence is much lower than it is in northern california. here, we sought to discover the previously unknown microhabitats of nymphs of the primary vector, the western black-legged tick (ixodes pacificus), in 3 moderately to heavily-utilized state parks in the santa monica mountains in los angeles county; to elucidate the seasonal distribution and abundance of adults of i. pacificus and another ... | 2013 | 23643357 |
