| 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 |
| genotypic identification of three new strains of spotted fever group rickettsiae isolated in china. | polymerase chain reaction (pcr) and restriction endonuclease fragment length polymorphism (rflp) analysis were used to characterize the genotypic diversity of three isolates of spotted fever group (sfg) rickettsiae isolated from ticks in china. a primer pair designed from dna sequence encoding 190 k protein antigen of r. rickettsii and genomic dnas obtained from the isolates were used in pcr. the pcr products were cleaved with restriction endonucleases psti and rsai, and the digestion patterns w ... | 1996 | 9014012 |
| 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 |
| sequence and annotation of rickettsia sibirica sibirica genome. | rickettsia sibirica sibirica is the causative agent of siberian or north asian tick typhus, a tick-borne rickettsiosis known to exist in siberia and eastern china. here we present the draft genome of rickettsia sibirica sibirica strain bj-90 isolated from dermacentor sinicus ticks collected in beijing, china. | 0 | 22493192 |
| sfts virus in ticks in an endemic area of china. | in total, 3,145 ticks of the species haemaphysalis longicornis (3,048; 96.9%), r. microplus (82; 2.6%), h. campanulata (9; 0.3%), and dermacentor sinicus (5; 0.2%) were collected from animals and vegetation at yantai in shandong province. both adult and immature ticks were obtained, and all ticks collected from vegetation were unfed. eggs were obtained from 22 blood-fed female ticks through maintenance at room temperature after collection. severe fever with thrombocytopenia syndrome virus (sftsv ... | 2015 | 25711611 |
| expression pattern of suba in different tissues and blood-feeding status in haemaphysalis flava. | tick-borne-diseases (tbd) pose a huge threat to the health of both humans and animals worldwide. tick vaccines constitute an attractive alternative for tick control, due to their cost-efficiency and environmental-friendliness. subolesin, a protective antigen against ticks, is reported to be a promising candidate for the development of broad-spectrum vaccines. however, the entire length of its gene, suba, and its gene expression pattern in different tissues and blood-feeding status (or different ... | 2016 | 27631766 |
| [epidemiological investigation of predominance tick and the infectious status of severe fever thrombocytopenia syndrome virus in penglai and laizhou counties, shandong province]. | to investigate the predominance ticks and the infectious status of severe fever with thrombocytopenia (sftsv) in penglai and laizhou counties, shandong province. | 2015 | 26833011 |
| molecular survey of hard ticks in endemic areas of tick-borne diseases in china. | over the past several years, there was a substantial increase in the number of cases of known and novel tick-borne infections in humans in china. to better understand the ticks associated with these infections, we collected hard ticks from animals or around livestock shelters in 29 localities in 5 provinces (beijing, henan, hubei, inner mongolia, and zhejiang) where cases of tick-borne illness were reported. we collected 2950 hard ticks representing 7 species of 4 genera (dermacentor sinicus, ha ... | 2013 | 23538111 |
