In total, 142 birds, mostly passerines, belonging to 42 species were examined for the presence of ticks in 3 locations in Mato Grosso do Sul Brazil during 2006. Seven birds (5%) were infested with 4 nymphs of Amblyomma calcaratum (Ramphocelus carbo, 3 infested/12 examined) and 5 larvae of Amblyomma sp. (Furnarius rufus, 2/5; Turd us leucomelas, 1/6; and Paroaria capitata, 1/8). All 4 nymphs of A. calcaratum tested by polymerase chain reaction targeting rickettsial genes gltA and ompA and by amplicon sequencing were found to be infected with a Rickettsia sp. strain NOD, a Rickettsia parkeri-like agent. A. calcaratum infected with a rickettsial bacterium was found for the first time.
