| genotypic and antigenic identification of two new strains of spotted fever group rickettsiae isolated from china. | four isolates of spotted fever group rickettsiae isolated from ticks in china were compared with all known species and strains of spotted fever group rickettsiae by immunofluorescence assay, dna polymerase chain reaction followed by restriction endonuclease fragment length polymorphism analysis, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and western immunoblot. the chinese isolates belonged to three types, including a novel serotype which has not been described before. one isolat ... | 1993 | 8093253 |
| [a molecular epidemiologic investigation of north asia fever in scenic spots of beijing suburb]. | pcr/rflp technique was used to detect spotted fever group rickettsiae (sfgr) in ticks and small mammals collected in eleven scenic spots of beijing suburb. we not only detected rickettsia sibirica in d. sinicus and hedgehog collected nearby the museum of aviation, but also isolated two strains of sfgr from them, named as bj-95 strain and bjh-95 strain respectively. the two strains were identified as r. sibirica by sds-page, western blot and pcr/rflp. the results demonstrated the existence of hor ... | 1997 | 9812516 |
| genetic differentiation of chinese isolates of rickettsia sibirica by partial ompa gene sequencing and multispacer typing. | current data on rickettsiae and rickettsial diseases in china remain limited. using partial ompa gene sequencing and multispacer typing, we identified 15 rickettsial isolates from china. all isolates were found to belong to rickettsia sibirica subsp. sibirica. four isolates from dermacentor sinicus collected in beijing, china, were fully identical to strain bj-90, previously demonstrated to belong to r. sibirica subsp. sibirica despite antigenic and genotypic specificities. all 11 remaining isol ... | 2006 | 16825365 |
