Summary: | Cases of tick-borne diseases, including spotted fever rickettsioses, borreliosis, babesiosis, anaplasmosis and ehrlichiosis, in the United States and territories have more than doubled from 2004 to 2016 and account for 77% of all vector-borne disease reports. 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
(96.69%) followed by three additional tick species:
(2.59%),
(0.52%), and
(0.21%). Ticks were pooled and tested for molecular evidence of bacterial and viral pathogens, respectively. All of the 68 pools of
had molecular evidence of the spotted fever group rickettsia,
Additionally, six (8.82%) of the
pools contained sequences matching
, the pathogen responsible for human monocytotropic ehrlichiosis, and 11 (16.18%) for
. Three of the
pools demonstrated evidence of
. 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. |
