In an effort to inform control efforts, the presence of tick-borne pathogens and their vectors was assessed in a recreational park in Walker County, Texas. Here we report data from questing ticks collected on three dates from June 2017 to June 2018. The majority of ticks collected were Amblyomma americanum (96.69%) followed by three additional tick species: Dermacentor variabilis (2.59%), Ixodes scapularis (0.52%), and A. maculatum (0.21%). Ticks were pooled and tested for molecular evidence of bacterial and viral pathogens, respectively. All of the 68 pools of A. americanum had molecular evidence of the spotted fever group rickettsia, Rickettsia amblyommatis. Additionally, six (8.82%) of the A. americanum pools contained sequences matching Ehrlichia chaffeensis, the pathogen responsible for human monocytotropic ehrlichiosis, and 11 (16.18%) for E. ewingii. Three of the A. americanum pools demonstrated evidence of Borrelia lonestari. The presence of etiologic agents of known human disease in this study merits the continued surveillance efforts of ticks and their pathogens in areas where they could pose risks to public health.<\/jats:p>","DOI":"10.3390\/insects10100315","type":"journal-article","created":{"date-parts":[[2019,9,26]],"date-time":"2019-09-26T03:06:51Z","timestamp":1569467211000},"page":"315","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Detection of Rickettsiae, Borreliae, and Ehrlichiae in Ticks Collected from Walker County, Texas, 2017\u20132018"],"prefix":"10.3390","volume":"10","author":[{"given":"Nicole","family":"Mendell","sequence":"first","affiliation":[{"name":"Department of Pathology, University of Texas Medical Branch, 301 University Boulevard, Galveston, TX 77555, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2847-0982","authenticated-orcid":false,"given":"Erin","family":"Reynolds","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology, SUNY Upstate Medical University, 505 Irving Avenue, Syracuse, NY 13210, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucas","family":"Blanton","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, University of Texas Medical Branch, 301 University Boulevard, Galveston, TX 77555, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meghan","family":"Hermance","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology, SUNY Upstate Medical University, 505 Irving Avenue, Syracuse, NY 13210, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4703-1387","authenticated-orcid":false,"given":"Andres","family":"Londo\u00f1o","sequence":"additional","affiliation":[{"name":"Department of Pathology, Uniformed Services University of the Health Sciences, 4301 Jones Bridge Road, Bethesda, MD 20814, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charles","family":"Hart","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology, SUNY Upstate Medical University, 505 Irving Avenue, Syracuse, NY 13210, USA"},{"name":"The Institution for Translational Sciences, University of Texas Medical Branch, 301 University Boulevard, Galveston, TX 77555, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bethany","family":"Quade","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, University of Texas Medical Branch, 301 University Boulevard, Galveston, TX 77555, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Allen","family":"Esterly","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology, SUNY Upstate Medical University, 505 Irving Avenue, Syracuse, NY 13210, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C\u2019Brionne","family":"Hendrix","sequence":"additional","affiliation":[{"name":"Department of Cell Biology, University of Texas Medical Branch, 301 University Boulevard, Galveston, TX 77555, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pete","family":"Teel","sequence":"additional","affiliation":[{"name":"Department of Entomology, Texas A&amp;M AgriLife Research, College Station, TX 77843, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5043-9068","authenticated-orcid":false,"given":"Donald","family":"Bouyer","sequence":"additional","affiliation":[{"name":"Department of Pathology, University of Texas Medical Branch, 301 University Boulevard, Galveston, TX 77555, USA"},{"name":"Center for Biodefense and Emerging Infectious Diseases, Sealy Institute for Vaccine Studies, Center for Tropical Diseases, University of Texas Medical Branch, 301 University Boulevard, Galveston, TX 77555, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saravanan","family":"Thangamani","sequence":"additional","affiliation":[{"name":"Department of Pathology, University of Texas Medical Branch, 301 University Boulevard, Galveston, TX 77555, USA"},{"name":"Department of Microbiology and Immunology, SUNY Upstate Medical University, 505 Irving Avenue, Syracuse, NY 13210, USA"},{"name":"SUNY Center for Environmental Health and Medicine, SUNY Upstate Medical University, 505 Irving Avenue, Syracuse, NY 13210, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,9,25]]},"reference":[{"key":"ref_1","unstructured":"Center for Disease Control and Prevention, National Center for Emerging and Zoonotic Infectious Diseases (NCEZID), and Division of Vector-Borne Diseases (DVBD) (2019, August 05).
