Disease manifestations are strikingly similar in both species, and illness in dogs can precede illness in people. <jats:italic>R. rickettsii<\/jats:italic> has been identified as a Select Agent by the CDC as a Category C priority pathogen by the National Institute of Allergic and Infectious Diseases because it is amenable to use as a bioterror agent. The clinical and temporal relationship of naturally occurring diseases in dogs and people suggests that dogs could serve as sentinels for natural infection and bioterrorist attacks using this organism. Recognizing genetic modifications in naturally occurring disease agents in order to distinguish them from intentionally released agents are priorities put forth by the NIAID. To determine whether the rickettsiae naturally infecting dogs is the same as those that infect persons in a given geographical region, we characterized rickettsial isolates obtained from three dogs and two persons diagnosed with RMSF in North Carolina. Portions of three genes (<jats:italic>ompA,<\/jats:italic><jats:italic>rrs<\/jats:italic>, and <jats:italic>gltA<\/jats:italic>) amplified by PCR were cloned and sequenced or directly sequenced. Reactions were run in duplicate in forward and reverse directions. Gene sequences were aligned with known sequences deposited in GenBank and with each other. Sequences of the 5\u2032 region of the ompA gene were 100% homologous with a tick strain (Bitterroot) of <jats:italic>R. rickettsii<\/jats:italic> for all five isolates. Sequences of the <jats:italic>rrs<\/jats:italic> gene were 99.8 99.9% homologous with a tick strain (Sawtooth) of <jats:italic>R. rickettsii<\/jats:italic>. <jats:italic>rrs<\/jats:italic> gene sequences from one dog and the two persons was identical. Sequences of one dog isolate differed from these by one base pair. Sequences from another dog isolate differed by two base pairs. Sequences of the <jats:italic>gltA<\/jats:italic> gene are pending. This confirms on a molecular level that <jats:italic>R. rickettsii<\/jats:italic> causing naturally occurring RMSF in dogs in North Carolina is highly homologous to <jats:italic>R. rickettsii<\/jats:italic> that causes the disease in people in the same region. Sequence data will be deposited in GenBank, thereby providing genetic information regarding naturally occurring <jats:italic>R. rickettsii<\/jats:italic>.<\/jats:bold> <\/jats:p>","DOI":"10.1196\/annals.1374.079","type":"journal-article","created":{"date-parts":[[2006,11,18]],"date-time":"2006-11-18T02:13:56Z","timestamp":1163816036000},"page":"400-409","source":"Crossref","is-referenced-by-count":11,"title":["Molecular Characterization of <i>Rickettsia rickettsii<\/i> Infecting Dogs and People in North Carolina"],"prefix":"10.1111","volume":"1078","author":[{"given":"LINDA","family":"KIDD","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"BARBARA","family":"HEGARTY","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"DANIEL","family":"SEXTON","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"EDWARD","family":"BREITSCHWERDT","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,10,31]]},"reference":[{"key":"e_1_2_6_2_2","first-page":"87","article-title":"Rickettsial disease: classical and modern aspects","volume":"27","author":"Rizzo M.","year":"2003","journal-title":"New Microbiol."},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1128\/CMR.10.4.694"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1128\/jcm.35.11.2715-2727.1997"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.2460\/javma.2002.221.1413"},{"key":"e_1_2_6_6_2","unstructured":"http:\/\/www.cdc.gov\/ncidod\/dvid\/rmsf\/organism.htm."},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.4269\/ajtmh.2002.67.349"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.5326\/15473317-37-1-41"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1093\/infdis\/135.6.911"},{"key":"e_1_2_6_10_2","first-page":"851","article-title":"Studies on the pathogenesis of Rickettsia rickettsii in the dog: clinical and clinicopathologic changes of experimental infection","volume":"38","author":"Keenan K.P.","year":"1977","journal-title":"Am.
