title: Nodular trombiculinosis caused by Apolonia tigipioensis, Torres and Braga (1938), in an ostrich (Struthio camelus) and a house sparrow (Passer domesticus).
abstract: Nodular trombiculinosis has been reported in Brazil in chickens [Torres, S., Braga, W., 1939. Apolonia tigipioensis, g. e sp. n. (Trombiculinae) parasito de Gallus gallus dom. Chave para determinação de gêneros. Boletim da S.A.I.C. 4, 37-44] and humans [Carneiro, L.S., 1952. Uma nova acaríase humana - Contribuição ao seu estudo. Imprensa Industrial, Recife. Faculdade de Medicina da Universidade do Recife, Tese Livre Docência, p. 56]. In this report, a juvenile ostrich and a house sparrow, both originating from a riverside property in the town of Petrolina in the state of Pernambuco, presented 87 and eight nodules, respectively, on various locations of their bodies. Physical expression of the nodules liberated parasites that were morphologically identified as mites from the family Trombiculidae. The mites were further identified as Apolonia tigipioensis by the presence of an elongated body form and transversely striated, three pairs of long legs each with seven segments, primary coxae with a single seta, each tarsus terminating with three claws, and a scutum with an anteromedian projection and paired anteromedian setae. Histopathologic examination of skin biopsies from these birds, stained with hematoxilin-eosin, revealed acute parasitic cystic lymphoplasmacytic dermatitis.
