| [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 |
| detection of spotted fever group rickettsia in haemaphysalis longicornis in hebei province, china. | abstract dna samples from 737 ticks pools, representing 6850 haemaphysalis longicornis and 51 dermacentor nuttalli ticks collected from hebei province, china, were analyzed by pcr for the presence of spotted fever group rickettsia. there were 50 (6.9%) of 724 h. longicornis ticks pools found positive, but no positive samples found in 13 d. nuttalli. sequence analysis of the partial outer membrane protein a (ompa) genes from the ten positive samples showed 98% identity, but different from the hom ... | 2011 | 21506802 |
| molecular detection of anaplasma phagocytophilum in ixodid ticks in hebei province, china. | a total of 3696 ixodid ticks, collected from hebei province, china, were examined by a nested polymerase chain reaction for the presence of anaplasma phagocytophilum. forty-three (15.4%) of 280 pools tested, including 39 (14.6%) of 267 haemaphysalis longicornis and four (30.8%) of 13 dermacentor nuttalli, were positive, but no significant difference was found between d. nuttalli and h. longicornis (p>0.05). sequence and phylogenetic analyses of 16s rrna gene indicated that a. phagocytophilum in ... | 2011 | 21923254 |
| detection of borrelia burgdorferi from ticks (acari) in hebei province, china. | from may 1992 to august 1993, 1,196 ticks were collected by flagging vegetation and from domestic animals in chengde, zhangjiakou, shijiazhuang, and handan districts of hebei province. of those ticks collected, 954 were haemaphysalis japonicum warburton and h. longicornis neumann, 205 were ixodes persulcatus schulze, and 37 were dermacentor silvarum olenev. four strains of borrelia burgdorferi were isolated from 135 i. persulcatus collected in weichang and zhuolu counties. three of 574 haemaphys ... | 1998 | 9538567 |
