This study verified the occurrence of Bartonella spp. in dogs, cats, wild mammals and their ectoparasites Petrolina Lagoa Grande Counties, Pernambuco, located a semi-arid region Northeastern Brazil. Anti-Bartonella antibodies were detected by indirect immunofluorescence assay (IFA) 24.8% dogs (27/109) 15% cats (6/40). sp. DNA was identified PCR performed on extracted from blood using primers targeting gltA ribC genes 100% (9/9) Pulex irritans Cerdocyon thous, 57.4% (35/61) P. 2.3% (1/43)...
We conducted a molecular survey for Borrelia spp. in Ornithodoros ticks previously reported as biting humans. collected specimens natural ecosystems and inside human dwellings 6 states Brazil. Phylogenetic analyses unveiled the occurrence of 4 putatively new species relapsing fever group borreliae.
Tick-borne relapsing fever group (RFG) borreliosis remains neglected as a human disease and little is known on its maintenance in ticks vertebrates, especially South America. Therefore, this study investigated borrelial infection Ornithodoros collected rodent-inhabited rock formations the Brazilian semiarid region, within Caatinga biome. Collected (Ornithodoros rietcorreai cf. tabajara) were allowed to feed under laboratory conditions guinea pigs, which had blood samples examined daily by...
This study aimed to detect, isolate and characterize by molecular methods a relapsing fever group (RFG) Borrelia in white-eared opossums (Didelphis albiventris) from Brazil. During 2015–2018, when spp.) were captured six municipalities of the state São Paulo, Brazil, analyses revealed presence novel RFG sp. blood seven albiventris), out 142 sampled (4.9% infection rate). All infected single location (Ribeirão Preto municipality). In subsequent field Ribeirão during 2021, two new (D....
Abstract Coxiella burnetii is a zoonotic agent transmitted mainly by small ruminants. In Brazil the disease has been classified as notifiable since 2013, when human cases were reported. This study aimed to identify risk factors associated with presence of anti- antibodies in goats and sheep semiarid region Northeastern Brazil. Sera 412 403 from municipality Petrolina, Pernambuco, examined Indirect Fluorescent Antibody Test (IFAT) against antigens C. burnetii. Information about management...
This study evaluated rickettsial infection in Amblyomma rotundatum ticks collected from toads (Rhinella jimi) the Brazilian Caatinga biome, an unique semiarid region of South America. Tick infestations were observed 57.8% (26/45); mean infestation: 1.6 ticks/toad. DNA extraction 42 (6 larvae, 22 nymphs and 11 female adults) was tested by polymerase chain reaction (PCR) targeting Rickettsia organisms, which detected 100% ticks. Amplicons' sequences identical to each other 99% bellii GenBank....
Abstract This study aimed to determine the seroprevalence, factors associated with seropositivity Leishmania infection in dogs and spatial analysis six municipalities semiarid region of Pernambuco, Brazil. Blood samples were collected from 462 dogs, 77 each municipality, used for serological [dual path platform (DPP®) enzyme-linked immunosorbent assay (ELISA)]. Clinical signs evaluated analyzed using robust Poisson regression model. A seroprevalence 42.8% (198/462, IC: 95% = 38.6%-47.6%) was...
In this study, we report soft ticks from bat-inhabiting caves in different areas of Brazil. From 2010 to 2019, collected 807 tick specimens nine located four Brazilian states among two biomes. Ticks were morphologically identified as Antricola guglielmonei (282 specimens), Ornithodoros cavernicolous (260 and fonsecai (265 specimens). Whereas A. was on bat guano hot caves, O. cracks crevices the walls cold sometimes same chamber. Morphological identifications corroborated by molecular...
The species Pseudoschoengastia petrolinensis n. sp. is described and illustrated below from specimens discovered parasitizing a white-eared opossum, Dildelphis albiventris Lund (Didelphimorphia, Didelphidae), in Carneiros, Petrolina municipality, Pernambuco state, Brazil. In addition the Eutrombicula spipi Quadraseta falconensis are also new records to D. host record batatas, E. spipi, Q. falconensis, state of locality for all these...
Abstract The bacterial genus Borrelia comprises vector-borne spirochetes that have been classified into three major groups: the relapsing fever group (RFG), burgdorferi Johnson, Schmid, Hyde, Steigerwalt & Brenner sensu lato (Bbsl), and reptile-monotreme (RMG). All groups associated mainly with ticks wild animals, especially rodents, birds, reptiles. Here, we searched for infection among 99 vampire bats [Desmodus rotundus (É. Geoffroy)] (Chiroptera: Phyllostomidae) from Brazilian...
Abstract Brazilian spotted fever (BSF) is a common tick-borne disease caused by Rickettsia rickettsii. Horses are the primary hosts of main vector, Amblyomma sculptum, and considered efficient sentinels for circulation Rickettsia. Therefore, aim this study was to detect antibodies reactive R. rickettsii antigens in horses from non-endemic area north-central region Bahia state, Brazil. Blood samples ticks were collected 70 municipalities Senhor do Bonfim, Antônio Gonçalves, Pindobaçu, Campo...
RESUMO A Caatinga é um bioma exclusivamente brasileiro e dos mais diversificados do mundo, abrigando grande variedade faunística. Este estudo objetivou relatar a presença de carrapatos em tamanduás Tamandua tetradactyla (Linnaeus, 1758) atendidos no Centro Conservação Manejo Fauna da Caatinga, Petrolina-PE, Brasil. De fevereiro 2010 2016, 23 T. foram recebidos inspecionados para avaliação carrapatos. identificação foi realizada pela observação das características morfológicas utilização...
Leptus Latreille is the most diverse genus of Erythraeidae Robineau-Desvoidy, with 275 species (based on larval stage) worldwide described. Their stage parasitizes different arthropods. Until date, 12 have been registered for Brazil. In this study, we identified first time a larva parasitizing an adult Ornithodoros soft tick in This record mite argasid tick, and increases known number Brazil to 13.
Abstract The domestic cat is not considered a primary host for any specific tick species; however, it can be affected by some Ixodidae species, such as Rhipicephalus sanguineus sensu lato and Amblyomma spp. study reports parasitism auricularium the detection of anti-Rickettsia antibodies in cats from rural property Afrânio municipality, Pernambuco, Brazil. (24 nymphs, six females, four males) sp. (42 larvae) parasitized three cats, 73 free-living ticks were captured armadillo burrows: A. (36...
Abstract The Brazilian tick fauna currently comprises 77 valid species categorized into two families: Ixodidae (53 species) and Argasidae (24 species). In the state of Alagoas, only six Ixodid ticks have been reported to date, with no previous reports in family. Here, we assessed 33 White-eared Opossum (Didelphis albiventris Lund, 1840) rescued metropolitan region Maceió referred Wild Animal Screening Center (Cetas) city. Upon arrival, animals were examined for ectoparasites within 24 hours....
