The larvae of the family Trombiculidae are ectoparasites of vertebrates, including birds. The bite of some species can cause deep lesions and severe skin reactions in the host, these can lead to dermatitis, popularly known as trombiculiasis. A morphological study of chiggers collected on birds from the state of Minas Gerais in Southeastern Brazil discovered Blankaartia sinnamaryi-infestation on Passeriformes birds. Molecular studies of the disclosed the 18S rDNA sequences of the mite, and the detection of a Rickettsia sp. in this chigger mite species.
恙螨科幼虫是包括鸟类在内的脊椎动物的体外寄生虫。某些种类的叮咬会在宿主身上引起深部损伤和严重的皮肤反应，这些反应可能导致皮炎，俗称恙螨病。对从巴西东南部米纳斯吉拉斯州鸟类身上采集的恙螨进行的形态学研究发现，雀形目鸟类感染了辛纳马里布兰卡恙螨。对该恙螨的分子研究揭示了其18S rDNA序列，并在这种恙螨中检测到一种立克次氏体。
