The aim of this work was to compare the epidemiological and clinical characteristics of Rickettsia parkeririckettsiosis related to Amblyomma tristeand Amblyomma tigrinumecological regions in Argentina. We reviewed cases of R. parkeririckettsiosis from 2007 to 2017 evaluated at Muñiz Hospital, directly or through referral. Univariate analysis was used to examine the association between different variables and the disease related by each vector species. The eighteen cases of R. parkeririckettsiosis included had fever, inoculation eschar and all except one had rash. Regional differences in epidemiological variables were identified, depending on the vector. There was a significantly increased risk of exposure to A. tigrinumin peri-domestic areas (odd ratio 12, p = 0.02), whereas an increased risk of exposure to A. tristewas evident in wildlife areas (odd ratio 12, p = 0.02). Seasonality of R. parkeririckettsiosis differed based on its vector. Cases associated with A. tristeoccurred predominantly during spring and summer, whereas those associated with A. tigrinumoccurred during fall, winter, and springtime. Exanthema was maculopapular (13/18), maculo-vesicular (3/18) or petechial (1/18). No clinical differences were identified depending on the vector. |
