ticks (acari: ixodidae) infesting wild birds in the atlantic forest in northeastern brazil, with notes on rickettsial infection in ticks.	a total of 232 individuals representing 46 species of birds were mist-netted and screened for ticks in a region of the atlantic forest, state of bahia, brazil. thirty-eight (16.4%) of these birds representing 17 species were found infested by immature stages of amblyomma ticks, namely, amblyomma longirostre (koch, 1844) (15 larvae and seven nymphs), amblyomma nodosum (neumann, 1899) (nine nymphs), amblyomma calcaratum (neumann, 1899) (five nymphs), amblyomma cajennense (fabricius, 1787) (seven l ...	2010	20953629
importation of exotic ticks and tick-borne spotted fever group rickettsiae into the united states by migrating songbirds.	birds are capable of carrying ticks and, consequently, tick-transmitted microorganisms over long distances and across geographical barriers such as oceans and deserts. ticks are hosts for several species of spotted fever group rickettsiae (sfgr), which can be transmitted to vertebrates during blood meals. in this study, the prevalence of this group of rickettsiae was examined in ticks infesting migratory songbirds by using polymerase chain reaction (pcr). during the 2009 and 2010 spring migratio ...	2013	24252263
rickettsial agents in avian ixodid ticks in northeast brazil.	birds are important in the maintenance and spread of ticks and tick-borne diseases. in this context we screened birds in the atlantic forest north of the são francisco river and caatinga in northeast brazil. in the atlantic forest amblyomma longirostre, amblyomma nodosum, amblyomma varium and amblyomma auricularium were identified. a. longirostre was infected by "candidatus rickettsia amblyommii" and a. nodosum by a rickettsia parkeri-like agent. in caatinga, amblyomma parvum and a. auricularium ...	2015	25800099
molecular detection of rickettsia rhipicephali and other spotted fever group rickettsia species in amblyomma ticks infesting wild birds in the state of minas gerais, brazil.	the current study evaluated parasitism of wild birds by ticks in a fragment of atlantic forest in the state of minas gerais, brazil, and examined the ticks for rickettsial agents. birds were captured during 2014 and 2015 and ticks were identified by sequencing fragments of the 16s and 12s ribosomal dna. among 260 birds representing 19 families and 52 species, a total of 69 (26.5%) were found to be infested by larvae (ll) and/or nymphs (nn) of amblyomma longirostre (koch, 1844) (45 ll, 4 nn), amb ...	2017	27745888
