| Abstract: | Adult ticks of the species Amblyomma parvum were collected from thevegetation in the Pantanal biome (state of Mato Grosso do Sul) and from horses in theCerrado biome (state of Piauí) in Brazil. The ticks wereindividually tested for rickettsial infection via polymerase chain reaction (PCR)targeting three rickettsial genes, gltA, ompA andompB. Overall, 63.5% (40/63) and 66.7% (2/3) of A.parvum ticks from Pantanal and Cerrado, respectively, containedrickettsial DNA, which were all confirmed by DNA sequencing to be 100% identical tothe corresponding fragments of the gltA, ompA andompB genes of Candidatus Rickettsia andeanae.This report is the first to describe Ca. R. andeanae in Brazil. |
