new species of chiggers trombidiformes trombiculidae and leeuwenhoekiidae from the conservation unit parque nacional da serra das confusoes brazil
Journal of Medical Entomology, 2021Co-Authors: Fernando De Castro Jacinavicius, Ricardo Bassinisilva, Darci Moraes Barrosbattesti, Matheus Huangbastos, Mauricio Claudio HortaAbstract:The Piaui State, Brazil, has never had its chigger fauna recorded. In this study, we examined chiggers collected on marsupials, rodents, and lizards from the conservation unit Parque Nacional da Serra das Confusoes (PNSC). Herein we describe four new species, Paraguacarus klompenin. sp., Neoschoengastia ochoain. sp., Quadraseta welbournin. sp., and Susa bauchanin. sp. Furthermore, an additional seven species are reported: Eutrombicula alfreddugesi (Oudemans, 1910), Microtrombicula brachytrichiaBrennan, 1971, Microtrombicula rhipidomysiGoff, Whitaker and Dietz, 1983, Parascoschoengastia aemulata (Brennan and Jones, 1964), Parasecia validaBrennan, 1969, Pseudochoengastia petrolinensis Jacinavicius, Bassini-Silva and Barros-Battesti 2019, and Quadraseta flochi (Brennan and Jones, 1960). This is the first report of chiggers in Piaui State, which includes one of the most biodiverse areas in the Caatinga biome and is of particular importance to conservation. The genera Paraguacarus Goff and Whitaker, 1984 and Susa Audy and Nadcharam, 1960 are reported here for the first time to Brazil.

Molecular detection of Rickettsia genus in chigger mites (Trombidiformes: Trombiculidae) collected on small mammals in southeastern brazilian
Revista Brasileira De Parasitologia Veterinaria, 2019Co-Authors: Fernando De Castro Jacinavicius, Ricardo Bassini-silva, Cal Welbourn, Sebastián Muñoz-leal, Marcelo Bahia Labruna, Darci Moraes Barros-battestiAbstract:Chiggers are ectoparasites of vertebrates and may cause trombiculiasis or transmit pathogens to their hosts. Specimens collected from rodents and marsupials were morphologically identified as Herpetacarus hertigi, Eutrombicula tinami, Kymocta sp., Quadraseta brasiliensis, Quadraseta falconensis, Quadraseta flochi, Quadraseta mackenziei, Quadraseta pazca, Quadraseta trapezoides, Quadraseta sp., Serratacarus sp., and Trombewingia bakeri. These mites were submitted individually to molecular analyses for the detection of bacteria of the genus Coxiella, Hepatozoon and Rickettsia. Samples were positive to Rickettsia only. Obtained sequences for the gltA (350 pb) and ompA (488 pb) genes were identical to "Candidatus Rickettsia colombianensi", a species previously detected in ticks. In addition, molecular identification of mites based on 18S rDNA sequences are provided for H. hertigi, Kymocta sp., Q. brasiliensis, Q. pazca, Q. trapezoides, Quadraseta sp., and T. bakeri for the first time. This is the first report of the detection of a Rickettsia sp. in chigger mites collected on rodents in Brazil.

Eutrombicula tinami oudemans 1910 trombidiformes trombiculidae in brazil a neglected ectoparasite of several animals including humans
Systematic & Applied Acarology, 2019Co-Authors: Ricardo Bassinisilva, Fernando De Castro Jacinavicius, Cal Welbourn, Adriano Pinter, Gislene F S R Fournier, Camile Lugarini, Ariane Ferreira, Luciano Moreiralima, Erika Hingstzaher, Ron OchoaAbstract:The genus Eutrombicula comprises ca. 80 species worldwide, some of which have been reported as causative agents of severe irritation to the host’s skin, known as trombiculiasis. Six species of Eutrombicula have been recorded from Brazil until present, with two reports of humans as hosts. In this study, Eutrombicula tinami (Oudemans) is redescribed and new records for the states of Minas Gerais, Rio de Janeiro, Santa Catarina and Sao Paulo as well as new parasite-host associations with Columbiformes, Cuculiformes, Passeriformes, Tinamiformes, Carnivora, Didelphimorphia and Lagomorpha are listed. Besides that, a two detailed report cases of trombiculiasis is provided.

description of parasecia fernandae sp n trombidiformes trombiculidae and new records of chiggers from rodents in rio de janeiro state brazil
Acarina, 2018Co-Authors: Fernando De Castro Jacinavicius, Darci Moraes Barrosbattesti, Marinete Amorim, Gilberto Salles Gazeta, Liege R Siqueira, Warren C Welbourn, Usa Consumer Services GainesvilleAbstract:In this article, we describe a new species of chiggers, Parasecia fernandae sp.n., and report the presence of Arisocerus hertigi (Brennan et Jones, 1964), Eutrombicula goeldii (Oudemans, 1910), Microtrombicula brachytrichia Brennan, 1971, Parasecia manueli (Brennan et Jones, 1960), Quadraseta brasiliensis Goff et Gettinger, 1989 and Serratacarus dietzi Goff et Whitaker, 1984, for the first time in Rio de Janeiro State. P. manueli is a new record for Brazil. All of these species of chiggers were found parasitizing Nectomys squamipes (Brants, 1827). Besides that, A. hertigi was found on Oxymycterus sp., and S. dietzi—on Cerradomys subflavus (Wagner, 1842).

First record of Eutrombicula tinami (Oudemans, 1910) (Trombidiformes: Trombiculidae) parasitizing a cat in Brazil
Parasitology Research, 2020Co-Authors: G. Cousandier, Ricardo Bassini-silva, Fernando C. Jacinavicius, Darci Moraes Barros-battesti, Matheus Huang-bastos, L. L. Dias CastroAbstract:Chigger mites are ectoparasites of terrestrial tetrapods and can cause dermatitis in the host, known as trombiculiasis. In Brazil, there are 73 species of chiggers; however, cats never have recorded as a host in this country. Here, we report the first record of chiggers parasitizing a domestic cat in Brazil; and a new locality for Eutrombicula tinami (Oudemans 1910 ) in the Rio Grande do Sul state, Brazil.

trombiculiasis in domestic goats and humans in the state of maranhao brazil
Revista Brasileira De Parasitologia Veterinaria, 2017Co-Authors: Joao Luiz Horacio Faccini, Fernando De Castro Jacinavicius, Ana Clara Gomes Dos Santos, Ricardo Bassinisilva, Sandra Batista Dos Santos, Darci Moraes BarrosbattestiAbstract:Trombiculiasis is an infestation caused by larval mites (chiggers) of the family Trombiculidae. Here, we provide the first report on parasitism by the chigger species Eutrombicula alfreddugesi (Oudemans) and Eutrombicula batatas (Linnaeus) in goats and humans on farms in the state of Maranhao, northeastern Brazil. Severe itching and dermatitis caused by the chiggers' bites were seen. From a total of 779 examined goats, 214 of them showed clinical signs of infestation, as well as family members of three farms of the region. Most of the cases occurred during the rainy season, from March to September.
