To better understand the prevalence and risk factors for spotted fever group <jats:italic>Rickettsia<\/jats:italic> (SFGR) and typhus group <jats:italic>Rickettsia<\/jats:italic> (TGR) along the Texas\u2013Mexico border, we conducted a seroprevalence study of adults residing in Starr County, Texas (<jats:italic>N<\/jats:italic> = 616). Plasma samples were screened for IgG reactivity to SFGR and TGR using commercially available ELISA. ELISA-positive samples were confirmed using a dual spot IgG indirect immunofluorescent assay. Seropositivity was defined as having a \u22651:128 titer. Analysis was conducted to assess risk factors associated with seropositivity. A higher seroprevalence of TGR (10.9%) was identified compared with SFGR (4.6%) and <jats:italic>Rickettsia<\/jats:italic> unspecified (2.0%). These findings add to the growing body of evidence suggesting that both SFGR and TGR are endemic along the Texas\u2013Mexico border.<\/jats:p>","DOI":"10.4269\/ajtmh.24-0528","type":"journal-article","created":{"date-parts":[[2025,3,11]],"date-time":"2025-03-11T20:26:58Z","timestamp":1741724818000},"page":"1116-1119","source":"Crossref","is-referenced-by-count":0,"title":["The Seroprevalence and Risk Factors for Spotted Fever Group and Typhus Group Rickettsia Along the Texas\u2013Mexico Border"],"prefix":"10.4269","volume":"112","author":[{"given":"Frederick M.","family":"Cramer","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Baylor College of Medicine and Texas Children\u2019s Hospital, Houston, Texas;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lauren M.","family":"Leining","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Baylor College of Medicine and Texas Children\u2019s Hospital, Houston, Texas;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Timothy A.","family":"Erickson","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Baylor College of Medicine and Texas Children\u2019s Hospital, Houston, Texas;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Josephine","family":"Tolan","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Baylor College of Medicine and Texas Children\u2019s Hospital, Houston, Texas;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Craig L.","family":"Hanis","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, Biostatistics, and Environmental Sciences, School of Public Health, University of Texas Health Science Center at Houston, Houston, Texas"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eric L.","family":"Brown","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, Biostatistics, and Environmental Sciences, School of Public Health, University of Texas Health Science Center at Houston, Houston, Texas"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sarah M.","family":"Gunter","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Baylor College of Medicine and Texas Children\u2019s Hospital, Houston, Texas;"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2795","reference":[{"key":"b1","series-title":"Front Public Health","first-page":"177","article-title":"Pathogenic landscape of transboundary zoonotic diseases in the Mexico\u2013US border along the Rio Grande","volume":"2","author":"Esteve-Gassent","year":"2014"},{"key":"b2","series-title":"Ann NY Acad Sci","first-page":"516","article-title":"The changing picture of murine typhus in the United States","volume":"70","author":"Pratt","year":"1958"},{"key":"b3","series-title":"Emerg Infect Dis","first-page":"179","article-title":"Rickettsial pathogens and their arthropod vectors","volume":"4","author":"Azad","year":"1998"},{"key":"b4","series-title":"Emerg Infect Dis","first-page":"645","article-title":"Typhus group rickettsiosis, Texas, United States, 2003\u20132013","volume":"23","author":"Murray","year":"2017"},{"year":"2019","key":"b5","article-title":"Annual Reported Cases of Notifiable Diseases, by Region and Reporting Area, United States and U.S. Territories, Excluding Non-U.S. Residents"},{"year":"2023","key":"b6","article-title":"Texas Notifiable Conditions.
