RESUMEN
Despite the worldwide occurrence and high genetic diversity of Bartonella spp. in bats, few studies investigate their occurrence in bat-associated mites. To date, 26 species of Macronyssidae mite species have been reported from Brazil, and 15 of which were found parasitizing bats. The present study aimed to investigate the presence of Bartonella DNA in bat-associated macronyssid mites from Brazil. For this purpose, 393 macronyssid specimens were selected by convenience from the tissue bank of the Acari Collection of the Instituto Butantan (IBSP). These mites were collected from 14 different bat species in three different Brazilian States (Minas Gerais, Paraná, and Rio de Janeiro). Out of 165 mites positive in the PCR for the endogenous 18S rRNA gene, only eight were positive in the qPCR for Bartonella spp. based on the nuoG gene, and we were able to obtain two sequences base in this same gene, and one sequence based on the 16S rRNA gene. The phylogenetic inference based on the nuoG gene grouped the obtained sequences with Bartonella genotypes previously detected in bats and associated bat flies, while the phylogeny based on the 16S rRNA grouped the obtained sequence in the same clade of Bartonella genotypes previously detected in Dermanyssus gallinae. These findings suggest that macronyssid mites might be associated with the maintenance of bartonellae among bats.

Species of the genus Ultratenuipalpus bear a broad subquadrate propodosoma with many large, flattened, lanceolate to ovate dorsal setae. They also bear some plesiomorphic character states, such as the presence of three pairs of ventral ps setae. Here, we describe Ultratenuipalpus parameekeri Castro, Ochoa & Feres sp. nov. based on adult females, males, and immatures, collected on ferns from Brazil. We also re-describe Ultratenuipalpus meekeri (De Leon), the type species of the genus, based on types and newly collected material from Mexico, and include additional novel data (e.g., dorsal and ventral ornamentation, leg chaetotaxy, and setal measurements) in a standardized form. We include highly detailed images obtained using LT-SEM, accompanied by DNA barcodes, for both species. The ontogenetic additions of leg chaetotaxy are presented and discussed.
RESUMEN
Ornithonyssus bursa, known as the "tropical fowl mite," is a hematophagous mite of domestic and wild birds, which occasionally bites humans. Accidental bites on humans occur mainly when abandoned bird nests are close to homes or when people are handling parasitized birds. In the present study, we describe five case reports of bites on humans and new records of localities for this species. Based on the material examined, we provide morphological and molecular characterizations for this species herein.

Macronyssid mites are ectoparasites of terrestrial vertebrates. We slide-mounted and re-examined mite material collected in a 1987-1989 expedition to Maracá Ecological Station, Roraima State, Brazil. The specimens were identified as Acanthonyssus proechimys Yunker and Saunders (Mesostigmata: Macronyssidae), which were collected parasitizing a South American spiny rat, Proechimys sp. This represents the first record of Acanthonyssus in Brazil.(AU)
Os ácaros macronissídeos são ectoparasitas de vertebrados terrestres. Nós montamos e reexaminamos material de ácaros coletado em uma expedição entre 1987-1989 à Estação Ecológica de Maracá, Estado de Roraima, Brasil. Os espécimes foram identificados como Acanthonyssus proechimys Yunker e Saunders (Mesostigmata: Macronyssidae), que haviam sido coletados parasitando um echimídeo sul-americano, Proechimys sp. Este é o primeiro registro de Acanthonyssus no Brasil.(AU)

Macronyssid mites are ectoparasites of reptiles, birds, and mammals (mainly bats). Out of 35 genera in this family, Radfordiella Fonseca, 1948 is a genus from the Neotropical region with six valid species, found parasitizing phyllostomid bats. Only Radfordiella desmodi Radovsky, 1967 and Radfordiella oudemansi Fonseca, 1948 have been registered in Brazil. The present study provides a new locality record for the species R. desmodi, microscopy images to aid in the identification, and a distribution map.
RESUMEN
Ornithonyssus bursa (Berlese, 1888), known as the tropical fowl mite, is a hematophagous mite of domestic and wild birds. This mite can bite humans accidentally, causing “gamasoidosis,” “avian-mite dermatitis,” or “bird-mite dermatitis” in tropical and subtropical regions of the world. In Brazil, O. bursa was previously recorded parasitizing birds of the orders Charadriiformes Huxley, 1867, Columbiformes Latham, 1790, Galliformes Temminck, 1820, Passeriformes Linnaeus, 1758, Strigiformes Wagler, 1830, and Tinamiformes Huxley, 1872. Here, we provide a new association of O. bursa with Harris’s hawk, Parabuteo unicinctus (Temminck, 1824) (Accipitriformes: Accipitridae) and the first record of this mite species in the Paraíba State, Brazil.

RESUMEN
Abstract Ornithonyssus bursa, known as the "tropical fowl mite", is a hematophagous mite of domestic and wild birds, occasionally biting humans. Infestation on humans occurs mainly when the abandoned nests are close to homes, or by manipulation of infested birds by humans. In Brazil, this species occurs in the south and southeast of the country. In the present study we are reporting bites on humans, new localities records, host associations, and molecular information of O. bursa.
Resumo Ornithonyssus bursa, conhecido como "ácaro tropical de galinha", é um ácaro hematófago de aves domésticas e silvestres, ocasionalmente picando humanos. A infestação em humanos ocorre principalmente quando os ninhos abandonados de aves estão próximos de casas, ou pela manipulação de humanos de aves infestadas. No Brasil, esta espécie ocorre na região sul e sudeste do país. No presente estudo, estamos relatando picadas em humanos, registros de novas localidades de ocorrência, novo hospedeiro e informações moleculares de O. bursa.

The genus Pellonyssus Clark and Yunker, 1956 comprises 14 species worldwide that are associates of birds. One of these species, Pellonyssus gorgasi Yunker and Radovsky, 1966, parasitizes hummingbirds in the Americas. This study represents a new host association with Eupetomena macroura (Apodiformes: Trochilidae) and the first occurrence of this mite in the state of São Paulo.
