| high prevalence of "candidatus rickettsia andeanae" and apparent exclusion of rickettsia parkeri in adult amblyomma maculatum (acari: ixodidae) from kansas and oklahoma. | amblyomma maculatum (the gulf coast tick), an aggressive, human-biting, nearctic and neotropical tick, is the principal vector of rickettsia parkeri in the united states. this pathogenic spotted fever group rickettsia species has been identified in 8-52% of questing adult gulf coast ticks in the southeastern united states. to our knowledge, r. parkeri has not been reported previously from adult specimens of a. maculatum collected in kansas or oklahoma. a total of 216 adult a. maculatum ticks wer ... | 2015 | 25773931 |
| rickettsia parkeri and "candidatus rickettsia andeanae" in questing amblyomma maculatum (acari: ixodidae) from mississippi. | amblyomma maculatum koch (acari: ixodidae), the primary vector for rickettsia parkeri, may also be infected with a rickettsia of unknown pathogenicity, "candidatus rickettsia andeanae." infection rates with these rickettsiae vary geographically, and coinfected ticks have been reported. in this study, infection rates of r. parkeri and "ca r. andeanae" were evaluated, and rickettsial dna levels quantified, in 335 questing adult a. maculatum collected in 2013 (n = 95), 2014 (n = 139), and 2015 (n = ... | 2016 | 27773866 |
