Until recently, Amblyomma cajennense (Fabricius, 1787) was considered to represent a single tick species in the New World. Recent studies have split this taxon into six species. While A. complex or (sensu lato) (s.l.) is currently represented by two Brazil, stricto) (s.s.) and sculptum Berlese, 1888, their geographical distribution poorly known. The of Brazil determined morphological examination all lots large collections collecting new material during three field expeditions possible...
Amblyomma cajennense F. is one of the best known and studied ticks in New World because its very wide distribution, economical importance as pest domestic ungulates, association with a variety animal human pathogens. Recent observations, however, have challenged taxonomic status this tick indicated that intraspecific cryptic speciation might be occurring. In present study, we investigate evolutionary demographic history examine genetic structure based on analyses three mitochondrial...
Bats and their ectoparasites play a crucial role in understanding the ecology transmission of vector-borne pathogens, yet these dynamics remain poorly studied Portugal. This study aimed to investigate molecular occurrence bacteria (Anaplasma spp., Bartonella Ehrlichia Rickettsia spp.) protozoa (Babesia spp. Theileria cave-dwelling bats. were sampled from two caves Portugal, included wing mites (Spinturnix myoti), ticks (Ixodes simplex), bat flies (Penicillidia conspicua Nycteribia...
The tick species found in Brazil are reviewed. Today, 61 belonging to nine genera (Argas (1 sp.), Antricola (3 spp.), Carios (10 Ornithodoros Amblyomma (30 Dermacentor Haemaphysalis Ixodes (8 and Rhipicephalus (2 spp.)) regarded as endemic or established Brazil. presence of 11 (Amblyomma albopictum, fulvum, hirtum, multipunctum, pseudoparvum, scutatum, Aponomma omissum, Argas persicus, puertoricensis, pararicinus, turanicus) is doubtful requires confirmation. Reports americanum,...
A new species of argasid tick (Acari: Argasidae) is described from immature and adult specimens collected several localities in Brazil. complete morphological account provided for all postembryonic life stages, i.e., larva, nymph, female, male. Ornithodoros cavernicolous n. sp. the 113th genus. Morphologically, shares common features, e.g., presence well-developed cheeks legs with micromammillate cuticle, other bat-associated ticks included subgenus Alectorobius. In particular,...
The aim of the study was to evaluate rickettsial infection in ticks from wild birds Semidecidual and Atlantic Rainforest remnants three municipalities State Paraná, southern Brazil. Overall, 53 larvae nymphs collected were checked for presence Rickettsia DNA by molecular tests. Five tick species tested: Amblyomma aureolatum (Pallas), calcaratum Neumann, longirostre (Koch), ovale Koch, parkeri Fonseca Aragão. A. infected with spotted fever group agents amblyommii strain AL (32.3% rate) NOD...
Most argasid ticks from the Neotropical region are parasites of mammals and birds, with a few records reptiles. Many species genus Ornithodoros known only through larval descriptions, their chaetotaxy morphological characteristics have been used to separate taxa. In present study, we describe larva nymph first instar new that was collected frogs Thoropa miliaris.Larvae were T. miliaris at waterfalls in state Rio de Janeiro, southeastern Brazil. The nymphal description based on optical...
Borrelia burgdorferi (sensu lato) is a complex containing pathogenic bacteria of which some species, such as lusitaniae, use birds, small mammals and reptiles reservoirs. In Italy, the have been detected in reptilian avian reservoirs northern central regions. Here, 211 from three orders [Squamata (Sauria with seven species five families Ophidia 11 families), Crocodylia (one family two species), Testudines (two species)] were examined for ectoparasites molecular detection B. (s.l.) different...
A checklist of the family Trombiculidae and Leeuwenhoekiidae is presented, containing 63 species in 30 genera chiggers from 80 different hosts 146 localities Brazil. The type locality depository are provided, including new host records for country.
The tick collection of the Museu de Historia Natural Capão da Imbuia was first sorted in end 80's, and a list specimens published 1992. During last ten years, has grown substantially became depository for type-specimens. is most regional representative ticks from State Paraná, it one four largest Brazilian collections number specimens. All material revised, data were computerized catalogued cards. To date, includes 504 vials, with 2,073 specimens, belonging to 25 species six genera families...
The bat tick Ornithodoros mimon Kohls, Clifford & Jones is currently known by only few reports in Bolivia, Uruguay, Argentina, and the state of São Paulo southeastern Brazil. Here, we expand distribution O. Brazil to states Minas Gerais (southeastern region), Goiás (central-western), Pernambuco, Rio Grande do Norte (northeastern). Ticks were collected on human dwellings, where there had been repeated complains bites persons during night. Tick generally followed intense inflammatory reactions...
SUMMARY Anaplasmataceae agents comprise obligate intracellular bacteria that can cause disease in humans and animals. Between August 2013 March 2015, 31 Nasua nasua (coati), 78 Cerdocyon thous (crab-eating fox), seven Leopardus pardalis (ocelot), 110 wild rodents, 30 marsupials, 42 dogs were sampled the Pantanal wetland, Brazil. In addition, ectoparasites found parasitizing animals collected identified. The present work aimed to investigate occurrence of mammals, domestic ectoparasites, by...
Spinturnicid mites are ectoparasites exclusively of bats. Herein, we provide a comprehensive catalogue spinturnicid species recorded in Brazil focusing on their distribution nationwide. This listed 16 into four different genera, and key for the genera Brazil. Also, it provides new locality records species: Cameronieta almaensis Almeida, Gettinger Gardner, Periglischrus acutisternus Machado-Allison, caligus Kolenati, iheringi Oudemans. Additionally, this study includes detailed discussion...
