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...
Abstract Background In recent years, Babesia and Bartonella species co-infections in patients with chronic, nonspecific illnesses have continued to challenge change the collective medical understanding of “individual pathogen” vector-borne infectious disease dynamics, pathogenesis epidemiology. The objective this case series is provide additional molecular documentation odocoilei infection humans Americas emphasize potential for co-infection a species. Methods development improved more...
The family Spinturnicidae comprises 110 species, 17 recorded in Brazil. These mites are exclusively ectoparasites of bats and can be found 13 different Chiropteran families. In this study, we provide 18S rRNA, 16S cox1 sequences for Periglischrus iheringi associated with Artibeus spp. We were able to identify species based on the examination type specimens. addition, recently collected material was used SEM micrographs further assist characterization widespread species.
Abstract Opossums are synanthropic animals that participate in the zoonotic transmission cycles. Chagas disease, a neglected tropical disease caused by Trypanosoma cruzi, affects many domestic and wild humans worldwide. This study aimed to determine occurrence of T. cruzi free-ranging opossums Canoinhas, Santa Catarina, Brazil. Fifty (Didelphis albiventris) (33 captured 17 road-killed) were evaluated using Nested-PCR assay. All tissue samples negative (0/17). Eight 33 (24.24%; 95%...
Domestic and wild felids are frequently parasitized by apicomplexan protozoa in the genus Cytauxzoon. Expanding species diversity has recently been described within this genus, with potential implications for epidemiology pathogenesis. In light of these findings, study assessed genetic Cytauxzoon spp. (n = 66) from different eco-regions Brazil Argentina. Of 66 blood samples analyzed, 53 (80.3%) were 18S rRNA gene PCR-positive spp., including 43 jaguars (Panthera onca) 10 ocelots (Leopardus...
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...
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...
Abstract Anaplasmataceae agents are obligatory intracellular Gram-negative α-proteobacteria that transmitted mostly by arthropod vectors. Although mammals of the Superorder Xenarthra (sloths, anteaters, and armadillos) have been implicated as reservoirs for several zoonotic agents, only few studies sought to detect in this group mammals. This study aimed investigate occurrence genetic diversity Anaplasma spp. Ehrlichia blood spleen samples free-living from four different states Brazil (São...
The lowland tapir (Tapirus terrestris) is the largest land mammal in Brazil and classified as a vulnerable species, according to assessment of risk extinction. present study aimed at investigating occurrence genetic diversity hemoplasmas free-ranging T. terrestris from Brazilian Pantanal Cerrado biomes. Blood samples were collected 94 living eight road-killed tapirs, totalizing 125 Conventional PCR targeting four different genes (16S rRNA, 23S RNAse P, dnaK) performed, obtained sequences...
The present study aimed to investigate, by molecular techniques, the occurrence of Anaplasmataceae, Bartonellaceae, Rickettsiaceae, Mycoplasmataceae, Coxiellaceae, and Babesiidae/Theileriidae agents in blood samples free-living wild boars (Sus scrofa) associated ticks south-eastern Brazil. For this purpose, 67 265 (264 Amblyomma sculptum one ovale) were analysed. In screening for Anaplasmataceae a PCR assay based on 16S rRNA gene, 5.97% 50.54% positive. Ehrlichia spp. dsb 9.24% Despite low...
Piroplasmids (order Piroplasmida) are a diverse group of tick-borne protozoa that may cause disease in animals and occasionally humans. Novel Piroplasmida clades species have been found wild from Brazil based on the phylogenetic assessment near-complete 18S rRNA, mitochondrial heat-shock protein genes. For instance, putative novel Babesia has detected capybaras Amblyomma ticks three Brazilian states. The present work aimed to describe, using assessments distinct molecular markers, this...
This study used serological and molecular methods to investigate the occurrence of vector-borne pathogens (VBP) with zoonotic potential in cats neutered at University Veterinary Hospital Canoinhas, Santa Catarina. The combined PCR results revealed that 17 (56.6%) were positive for one or more pathogens. sampled had antibodies Ehrlichia spp. (7/30), Anaplasma phagocytophilum (3/30) Leishmania infantum (2/30). assay detected DNA closely related canis 6/30 cats, Mycoplasma haemofelis 2/30 A....
Although mammals of the superorder Xenarthra are considered hosts a wide range zoonotic agents, works aiming at investigating role these animals as for bacteria with potential rare. The present study aimed to investigate occurrence and molecularly characterize Coxiella burnetii haemoplasma (haemotropic mycoplasmas) DNA in blood spleen samples from 397 free-living (233 sloths, 107 anteaters 57 armadillos) five Brazilian states (Mato Grosso do Sul, São Paulo, Pará, Rondônia Rio Grande Sul)....
The role of several feline vector-borne pathogens (FVBP) as a cause disease in cats has not been clearly determined. In fact, with the exception Bartonella spp. and hemoplasmas, FVBP determined Brazil yet. present study aimed at identifying, by using molecular methods, presence three showing non-specific clinical signs inclusions suggestive hemoparasites blood smears. Cytauxzoon felis, 'Candidatus Mycoplasma haemominutum', Ehrlichia sp. closely related to canis, Anaplasma phagocytophilum...
Despite numerous reports of Anaplasmataceae agents in mammals worldwide, few studies have investigated their occurrence birds. The present study aimed to investigate the and molecular identity birds from Pantanal wetland, Brazil. Blood samples were collected 93 different species. After DNA extraction, positive for avian β-actin gene subjected both a multiplex quantitative real-time (q)PCR Anaplasma Ehrlichia targeting groEL conventional PCR 16S rRNA gene. As result, 37 (7.4%) spp. 4 (0.8%)...
More than one-hundred Babesia species that affect animals and humans have been described, eight of which associated with emerging underdiagnosed zoonoses. Most diagnostic studies in used serology or molecular assays based on the 18S rRNA gene. Because gene is highly conserved, obtaining an accurate diagnosis at level difficult, particularly when amplified DNA fragment small. Also, due to its low copy number, sequencing product often unsuccessful. In contrast, because internal transcribed...
