Molecular evidence of Wolbachia in bat-associated mite Periglischrus Iheringi Oudemans, 1902 (Mesostigmata: Spinturnicidae) from Brazil.

Wolbachia is an intracellular endosymbiont bacterium found in nematodes and arthopods. Regarding mites, the Wolbachia supergroup U has been described based on strains found in the genus Spinturnix. In this study, ten specimens of Periglischrus iheringi (Mesostigmata: Spinturnicidae), collected from Artibeus obscurus (Chiroptera: Phyllostomidae) in Santa Catarina State, were found to be infected with Wolbachia.

New records of Spelaeorhynchus praecursor Neumann, 1902 (Mesostigmata: Spelaeorhynchidae) in the Brazilian Caatinga.

The Neotropical bat-ectoparasite family Spelaeorhynchidae comprises seven species into in one genus. The species Spelaeorhynchus praecursor is the most distributed in the region, parasitizing phyllostomid bats of the subfamilies Carolliinae, Glossophaginae and Stenodermatinae. The present study expands the known geographic distribution of this species, providing new host records, as well as the first SEM images detailing the main characteristics of this species.

Bottom-Up Proteomics Workflow for Studying Multi-organism Systems.

In recent years, discovery proteomics has emerged as a pivotal tool in biological research, especially when studying the intricate relationships among multiple organisms. To delve deeper into these interactions, we pioneered a bottom-up proteomics workflow. Using nanoLC-MS/MS and a label-free quantification method, this work specifically examines the differential protein expression in fleas (Ctenocephalides felis felis) that have been experimentally infected with Bartonella henselae, the causative agent of cat scratch disease (CSD).

Genetic diversity of Bartonella spp. in vampire bats and associated Streblidae bat flies in the Brazilian Amazon.

Among mammals, bats stand out as important reservoirs for Bartonella spp., second only to rodents. In Brazil, out of the 182 species of bats described, three are hematophagous: Desmodus rotundus, Diphylla ecaudata and Diaemus youngii.

Molecular survey of vector-borne agents in lowland tapirs (Tapirus terrestris) from Brazil reveals a new Anaplasma genotype.

Although vector-borne agents have been detected in different species of wild animals, studies involving tapirs (Tapirus terrestris), the largest land mammals in Brazil, are scarce. The aim of the present study was to investigate the occurrence and molecular identity of Anaplasmataceae agents, Coxiella burnetii and Hepatozoon spp. in blood samples of wild T.

Ticks and hemoplasma screening in dromedary camels (Camelus dromedarius) from Somalia.

Hemotropic mycoplasmas (hemoplasmas) are small pleomorphic bacteria that parasitize the surface of red blood cells of mammals. Hemoplasmas have been described in different species from the Camelidae Family, such as llamas and alpacas (South American camelids), but data on dromedary camels (Camelus dromedarius) are limited to a few reports. Somalia has one of the world's largest dromedary camel populations, and studies on hemoplasmas and tick-borne pathogens are lacking.

Bartonella spp. in bats from the Brazilian Amazon Forest.

Despite the great diversity of bats (64 species) in the State of Acre, northwestern Brazil, there are no studies on occurrence and diversity of Bartonella spp. in bats in this region. The present study investigated the occurrence and molecular identity of Bartonella spp.

Cytauxzoon brasiliensis sp. nov. (Apicomplexa: Theileriidae), a new species infecting a little-spotted-cat (Leopardus tigrinus) (Carnivora: Felidae) from Brazil.

Cytauxzoon spp. have been detected in Brazil infecting mainly asymptomatic domestic cats and wild felids. However, the supposed genetic similarity with the pathogenic Cytauxzoon felis is questionable because it is based on analysis of short sequences of the 18S rRNA gene.

A wingless fly on a winged mammal: host-parasite dynamics between Basilia travassosi (Diptera: Nycteribiidae) and Myotis lavali (Chiroptera: Vespertilionidae).

Nycteribiidae encompasses a specialized group of wingless blood-sucking flies that parasitize bats worldwide. Such relationships are frequently species- or genus-specific, indicating unique eco-evolutionary processes. However, despite this significance, comprehensive studies on the relationships of these flies with their hosts, particularly in the New World, have been scarce.

First report of unusual case of parasitism by Amblyomma nodosum (Neumann, 1889) in a yellow cururu toad (Rhinella icterica) in the Northeastern Brazilian Caatinga.

The Amblyomma genus (Arachnida: Ixodidae) is widely distributed in South America, with 34 species occurring in Brazil. Amblyomma nodosum Neumann 1889 is a species that predominantly feeds on Passeriformes during immature stages (larvae and nymphs) and anteaters (Myrmecophagidae) during adult stages. The aim of the present study is to report, for the first time, an unusual case of parasitism by adults of A.

Diversity of spp., spp. and spp. in vampire bats.

Although bats (Mammalia: Chiroptera) act as natural reservoirs for many zoonotic pathogens around the world, few studies have investigated the occurrence of agents in bats, especially vampire bats. The family (order Rickettsiales) encompasses obligate intracellular bacteria of the genera , , , , , and . The present study aimed to investigate, using molecular techniques, the presence of species of , , and in vampire bats sampled in northern Brazil.

Bartonella species in dromedaries and ruminants from Lower Shabelle and Benadir regions, Somalia.

Background: Bartonellosis, caused by bacteria of the genus Bartonella, is a zoonotic disease with several mammalian reservoir hosts. In Somalia, a country heavily reliant on livestock, zoonotic diseases pose significant public health and economic challenges. To the best of our knowledge, no study has been performed aiming to verify the occurrence of Bartonella spp.

Novel Tick-Borne Anaplasmataceae Genotypes in Tropical Birds from the Brazilian Pantanal Wetland.

Despite numerous reports of Anaplasmataceae agents in mammals worldwide, few studies have investigated their occurrence in birds. The present study aimed to investigate the occurrence and molecular identity of Anaplasmataceae agents in birds from the Pantanal wetland, Brazil. Blood samples were collected from 93 different species.

Phylogenetic inferences based on distinct molecular markers reveals a novel Babesia (Babesia pantanalensis nov. sp.) and a Hepatozoon americanum-related genotype in crab-eating foxes (Cerdocyon thous).

Piroplasmids and Hepatozoon spp. Are apicomplexan protozoa that may cause disease in several canid species. The present study aimed to expand the knowledge on the diversity of piroplasmids and Hepatozoon in crab-eating foxes (Cerdocyon thous; n = 12) sampled in the Pantanal of Mato Grosso do Sul State, central-western Brazil.

Post-mortem detection of hemoplasmas (hemotropic Mycoplasma spp.) in South American fur seal (Arctocephalus australis) sampled in Rio Grande do Sul State, southern Brazil.

Hemotropic mycoplasmas are bacteria that attaches to erythrocytes surface, which some species presents zoonotic concerns. In the suborder Pinnipedia, genera Otaria and Arctocephalus are prominent in Brazil. This study investigated the occurrence of hemoplasmas in Arctocephalus sp.

Molecular detection of Bartonella spp. in bat-associated macronyssid mites (Acari: Macronyssidae) from Southern and Southeastern Brazil.

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.
