| granulocytic ehrlichiae in ixodes persulcatus ticks from an area in china where lyme disease is endemic. | a total of 372 adult ixodes persulcatus ticks were collected from vegetation in a forest area of heilongjiang province in northeastern china, where lyme disease is known to be endemic. the ticks were examined for the presence of granulocytic ehrlichiae by heminested pcr with primers derived from the 16s rrna gene. of 310 ticks obtained from the dahe forestry farm, two pools (each containing 5 ticks) were found positive, with a minimum infection rate of 0.6%. ehrlichial dna was also detected in o ... | 2000 | 11060091 |
| sero-epidemiology of lyme disease in an endemic area in china. | a sero-epidemiological investigation on lyme disease was carried out in a forestry center of hailin county, heilongjiang province, china. a total of 381 participants including forestry workers and their dependents completed questionnaires and had blood samples taken for detection of antibody against borrelia burgdorferi by indirect immunofluorescent assay. of 381 participants, 250 (65.6%) had a history of tick bites between may and july, 1987, and 379 (99.5%) at some time in the past, 56 (14.7%) ... | 1994 | 7968682 |
| epidemiological and aetiological evidence for transmission of lyme disease by adult ixodes persulcatus in an endemic area in china. | involvement of adult ixodes persulcatus ticks in the transmission of lyme disease in hailin county, heilongjiang province, china, is reported. in 1986 from april through august adult i. persulcatus was the dominant tick in this endemic area with an infection rate of 43% for the lyme disease spirochaete, borrelia burgdorferi. the incidence of lyme disease cases presenting the symptom of erythema chronicum migrans (ecm) within this area was correlated with the seasonal abundance of adult i. persul ... | 1990 | 2083990 |
| [survey on tick vectors of lyme disease spirochetes in china]. | since 1987 we have been studying on lyme disease in china. there were 71 isolates of borrelia burgdorferi recovered from six species of ticks including ixodes persulcatus, ixodes granulatus, ixodes rangtangensis, haemaphysalis concinna. haemaphysalis bispinosa and haemaphysalis longicornis, and 55 isolates from ixodes persulcatus collected from heilongjiang, jilin, liaoning, nei-monggol, hebei and xinjiang region (province). ixodes persulcarus is the dominant species accounted for more than 80% ... | 1992 | 1300244 |
| investigation of borrelia spp. in ticks (acari: ixodidae) at the border crossings between china and russia in heilongjiang province, china. | to investigate the precise species of tick vector and the borrelia spirochete pathogen at the heilongjiang province international border with russia. | 2012 | 22575978 |
| development of real-time polymerase chain reaction for detection of borrelia burgdorferi sensu lato in china. | universal primers and probes were selected on the basis of the 16s rrna gene sequence of borrelia burgdorferi in genbank®, and a real-time polymerase chain reaction (pcr) method for detection of b. burgdorferi was established. the results showed that this method could specifically detect the b31 strain (borrelia burgdorferi sensu stricto), the bo23 strain (borrelia afzelii), and the sz strain (borrelia garinii), without cross-reaction with genome dna of theileria (t. luwenshuni, t. uilenbergi, t ... | 2012 | 22448677 |
| lyme borreliosis caused by diverse genospecies of borrelia burgdorferi sensu lato in northeastern china. | the variety of borrelia burgdorferi sensu lato (b. burgdorferi) genospecies leads to distinction in clinical manifestations of lyme borreliosis (lb). there are reports of lb clinical characteristics in china, where the b. burgdorferi genospecies in ticks and animal hosts are different from those in europe and north america. during may to september in 2010 and 2011, all patients who had erythema migrans (em, more than 5 cm in diameter) after a recent tick-bite, and sought medical care at mudanjia ... | 2014 | 24438159 |
| [investigation on the vectors of borrella burgdorferi and on the identification of the isolates along china-russia border in eastern heilongjiang province, china]. | to explore the fact that the east border of heilongjiang had been a lyme disease natural focus,we investigated the species and distribution of ticks and isolated bacteria from ticks and identified genomic species of borrelia burdorferi sensu lato. this study provided evidence for prevention and control of lyme disease. | 2007 | 17575937 |
| host associations and seasonal abundance of immature ixodes persulcatus (acari: ixodidae) in a lyme-disease-endemic area in china. | ticks of nine small mammal species were studied in an area of endemic lyme disease in hailin county, heilongjiang province, from 1 may to 10 october 1986. the bulk (93%) total small mammal captures were apodemus speciosus (45%), clethrionomys rufocanus (31%), a. agrarius (11%) and eutamias sibiricus; (5%): these host species accounted for 97% of the 162 ticks collected. ixodes persulcatus schulze were most abundant on e. sibiricus (0.64 larvae and 0.08 nymphs/squirrel), and less abundant on a. a ... | 1991 | 1773682 |
