ticks (acari: ixodidae) infesting wild birds in an atlantic forest area in the state of são paulo, brazil, with isolation of rickettsia from the tick amblyomma longirostre.during field work in nazaré paulista, state of são paulo, brazil, we found 13 (56.5%) of 23 birds (mostly passeriformes) to be infested by 28 larvae and 1 nymph of amblyomma spp. two larvae were reared to the adult stage, being taxonomically identified as amblyomma parkeri fonseca and aragio, whereas five larvae and one nymph were identified as amblyomma longirostre koch. all six a. longirostre specimens were shown to be infected by rickettsia, as demonstrated by polymerase chain reaction (pcr) ...200818714882
molecular evidence for a spotted fever group rickettsia species in the tick amblyomma longirostre in brazil.two amblyomma longirostre adult male ticks were collected from a brazilian porcupine coendou prehensilis l. in the state of rondonia, western amazon, brazil. the two ticks were pooled for dna extraction and tested for the presence of rickettsial dna by amplifying portions of the glta, 17-kda, ompa, and ompb rickettsial genes by polymerase chain reaction (pcr). portions of the four genes were amplified from the sample and subsequently sequenced. these results indicated the presence of a rickettsi ...200415185961
