RESUMO

Rickettsia has been receiving attention from several researcher groups around the world, once these bacteria can infect animals and human being. In this study, monthly, during the period of July, 2008 and June, 2009, was carried out at Núcleo Itutinga Pilões, localized in the Parque Estadual da Serra do Mar, a field research when ticks were collected from vegetation in six specific trials into the forest, overall were collected 455 adults, 1,939 nymphs and 46 larval agglomerates ticks. This study found out 13 different tick species (A. aureolatum, A. brasiliense, A. dubitatum, A. fuscum, A. incisum, A. longirostre, A. naponense, A. nodosum, A. ovale, Ixodes aragaoi, Ixodes loricatus. Haemaphysalis juxtakochi e Riphicephalus sanguineus). The majority found species were: A. incisum, H. juxtakochi and A. ovale. Three Rickettsia species were found naturaly infecting ticks in the park: R. parkeri, R. bellii e R. amblyommii. A. ovale ticks showed a R. parkeri infection prevalence of 11.7% for free-living ticks and 15.3% for ticks collected upon dogs. Ticks R. sanguineus collected feeding upon the same dogs as A. ovale were also found infected with R. parkeri. Since A. ovale ticks can attach onto human being, we predict that visitors of this park might be exposed to Spotted Fever Group Rickettsia infected ticks.
