The tick Amblyomma parkeri Fonseca and Aragão was described in 1952, based on female and immature ticks collected in the states of São Paulo and Santa Catarina, Brazil. Thereafter, there has been no further report of A. parkeri, and the male has remained unknown. Herein, we examined ticks collected on porcupines from a locality in the state of São Paulo. Some of the ticks were identified as Amblyomma longirostre (Koch, 1844), whereas others as A. parkeri, including male specimens, for which we provide the first description. We also provide additional reports of A. parkeri after examining collections of A. longirostre and Amblyomma geayi Neumann, 1899 from different tick collections. Morphological evidence to support the original description of A. parkeri is presented, supported by molecular analyses of portions of the 16S rRNA and 12S rRNA mitochondrial genes. Morphological particularities to separate A. parkeri, A. longirostre, and A. geayi are provided.

In Brazil, spotted fever (SF) is caused by two species of Rickettsia, both of which are transmitted by Amblyomma ticks: Rickettsia rickettsii, which results in severe and often fatal cases, and Rickettsia parkeri, which causes a mild illness. This study focused on R. parkeri in Amblyomma ovale ticks from the Maciço de Baturité region, Ceará, Northeast Brazil, an area endemic for SF with mild symptoms.

Article Synopsis
- Amblyomma maculatum is a significant tick species in the southwestern U.S. and northern Mexico, known for transmitting Rickettsia parkeri, which causes spotted fever.
- Monthly trapping and mist netting in Cochise County, Arizona revealed a total of 1949 ticks from various small mammals and birds, providing data on the tick's seasonal activity.
- The research indicated a univoltine life cycle tied to the North American monsoon seasons, with cotton rats having the highest infestation rates, suggesting they are key hosts in grass-dominated environments.

Article Synopsis
- * A total of 959 ticks were collected from companion animals and tested for various zoonotic pathogens using qPCR.
- * The survey identified five tick species and detected low prevalence rates for Rickettsia parkeri and Ehrlichia chaffeensis, pointing to the need for further monitoring and surveillance.

Infectious diseases, especially zoonotic, represent a significant global threat to both human and animal health. Ticks are among the primary vectors of pathogens affecting wild and domestic animals, some of which can also cause severe human diseases. To effectively face zoonotic diseases, the "One Health" approach is being promoted to integrate the health of human, animals, and ecosystems.
