Molecular Confirmation of Rickettsia parkeri in Amblyomma ovale Ticks, Veracruz, Mexico [PDF]
Emerging Infectious Diseases, 2019 We found Rickettsia parkeri in Amblyomma ovale ticks collected in Veracruz, Mexico, in 2018. We sequenced gene segments of gltA, htrA, sca0, and sca5; phylogenetic reconstruction revealed near-complete identity with R. parkeri strain Atlantic Rainforest.

Dynamics of Exposure toRickettsia parkeriin Cattle in the Paraná River Delta, Argentina [PDF]
Journal of Medical Entomology, 2016 Several cases of human rickettsiosis caused by Rickettsia parkeri were recently documented in the Paraná River delta of Argentina, where the tick vector is Amblyomma triste Koch. As cattle suffer recurrent A. triste infestations, they are at risk of becoming infected with R. parkeri Herein we investigated the dynamics of R. parkeri and its A.

Rickettsiosis Caused by Rickettsia parkeri, Mexico. [PDF]
Emerg Infect Dis, 2022 We report a human case of rickettsiosis caused by Rickettsia parkeri strain Atlantic Rainforest in Mexico in an adult woman from a small town in the north of Yucatan, Mexico. We confirmed diagnosis using conventional PCR and sequence analysis. Health providers should be aware of clinical manifestations of rickettsioses in this region.
