Abstract
Ixodid ticks are responsible for the transmission of various intracellular bacteria, such as the Rickettsia species. Little Information is available about the genetic characterization and epidemiology of Rickettsia spp. The current study was designed to assess the tick species infesting various livestock hosts and the associated Rickettsia spp. in Pakistan. Ticks were collected from different livestock hosts (equids, cattle, buffaloes, sheep, goats, and camels); morphologically identified; and s

Abstract
Spotted fever illness caused by the tick-borne pathogen Rickettsia parkeri has emerged in the Pampa biome in southern Brazil, where the tick Amblyomma tigrinum is implicated as the main vector. Because domestic dogs are commonly parasitized by A. tigrinum, this canid is also a suitable sentinel for R. parkeri-associated spotted fever. Herein, we investigate rickettsial infection in ticks, domestic dogs and small mammals in a natural reserve of the Pampa biome in southern Brazil. The ticks A. tig

Abstract
Objetivo. Informe sobre especies de garrapatas que parasitan a los humanos en un área del bioma semiárido de Caatinga, noreste de Brasil, con nota de infección por rickettsias. Materiales y métodos. Todas las garrapatas se identificaron morfológicamente con estereomicroscopio. Algunas de las garrapatas recolectadas se analizaron molecularmente para detectar la presencia de ADN de bacterias del género Rickettsia. Las garrapatas se sometieron individualmente a la extracción de ADN (gen de la citra
