چکیده

Background: tick-borne rickettsioses are considered important emerging zoonoses worldwide,but their etiological agents,rickettsiae,remain poorly characterized in northeastern china,where many human cases have been reported during the past several years. here,we determined the characteristics of rickettsia spp. infections in ticks in this area. methods: ticks were collected by flagging vegetation from jilin and heilongjiang provinces of northeastern china followed by morphological identification. the presence of rickettsia spp. in ticks was detected by pcr targeting the 23s-5s ribosomal rna intergenic spacer,citrate synthase (glta) gene,and 190-kda outer membrane protein gene (ompa). the newly-generated sequences were subjected to phylogenetic analysis using the software mega 6.0. results: the overall infection rate of rickettsia spp. was 6.12 %. phylogenetic analyses based on the partial glta and ompa genes demonstrated that rickettsiae detected in the ticks belong to four species,including candidatus rickettsia tarasevichiae
