Ticks (Acari: Ixodidae) collected from wild birds in Panama were tested for the presence of tick-borne pathogens as Rickettsia, Anaplasma, Ehrlichia, Bartonella, Borrelia, Hepatozoon sp., and Babesia. Overall 124 ticks were found in 57 birds belonging to 28 species: Amblyomma longirostre (32 larvae, 1 nymph), Amblyomma nodosum (30 nymphs), Amblyomma geayi (15 larvae, 1 nymph), Amblyomma varium (5 larvae, 2 nymphs), Amblyomma naponense (2 larvae), Amblyomma ovale (2 larvae), and Amblyomma calcaratum (1 larva). DNA of Rickettsia amblyommatis was detected in 65% of A. longirostre, 69% of A. geayi and 14% of A. varium. Moreover, results from two larvae of A. longirostre showed DNA of unidentified Rickettsia sp. No DNA of Borrelia, Bartonella, Anaplasmataceae neither Babesia nor Hepatozoon was detected. These results expand knowledge about the host for immature Amblyomma ticks in Panama and show the first data of Rickettsia in ticks collected from birds in this country.
