New genotypes of Anaplasmataceae agents have been detected in wild carnivores, birds and deer in Brazil. The present work aimed to investigate the presence of Ehrlichia and Anaplasma species in rodents sampled in Brazil. Additionally, a newly designed quantitative 5' nuclease real-time multiplex PCR for Ehrlichia and Anaplasma spp. detection based on groEL gene amplification was designed, showing high specificity and sensitivity (10 groEL fragment copy/μL). Between 2000 and 2011, different rodent species [n=60] were trapped in 5 Brazilian biomes. Among 458 rodent spleen samples, 0.4% (2/458) and 2.4% (11/458) were positive for Ehrlichia and Anaplasma spp., respectively. Of 458 samples, 2.0% (9/458) and 1.1% (5/458) were positive for Anaplasma sp. and Ehrlichia sp., respectively, using conventional 16S rRNA PCR assays. Maximum Likelihood phylogenetic analyse based on a small region of 16S rRNA genes positioned the Anaplasma genotypes in rodents near Anaplasma phagocytophilum or Anaplasma marginale and Anaplasma odocoilei isolates. Ehrlichia genotypes were closely related to E. canis. There was a low occurrence of Anaplasma and Ehrlichia in wild and synanthropic rodents in Brazil, suggesting the circulation of new genotypes of these agents in rodents in the studied areas.

“…The family Argasidae, known as soft ticks, comprises more than 200 species worldwide with 91 representatives in the Neotropics (NAVA et al, 2010;GUGLIELMONE et al, 2010;BARROS-BATTESTI et al, 2013VENZAL et al, 2015;MUÑOZ-LEAL et al, 2016a;LABRUNA et al, 2016). While in Brazil Argasidae is represented by 24 species belonging to Antricola, Argas, Nothoaspis, and Ornithodoros genera, at least 19 species belong to the genus Ornithodoros: Ornithodoros brasiliensis Aragão, 1923;Ornithodoros capensis Neumann, 1901; Ornithodoros fonsecai (Labruna & Venzal, 2009); Ornithodoros guaporensis Nava, Venzal & Labruna, 2013; Ornithodoros hasei (Schulze, 1935); Ornithodoros jul Schulze, 1940; Ornithodoros kohlsi (Guglielmone & Keirans, 2002); Ornithodoros marinkellei Kohls, Clifford & Jones, 1969; Ornithodoros mimon Kohls, Clifford & Jones, 1969;Ornithodoros nattereri Warburton, 1927; Ornithodoros rondoniensis (Labruna, Terrassini, Camargo, Brandão, Ribeiro & Estrada-Peña, 2008); Ornithodoros rostratus Aragão, 1911; Ornithodoros rudis Karsh, 1880; Ornithodoros setosus Kohls, Clifford & Jones, 1969; Ornithodoros stageri Cooley & Kohls, 1941; Ornithodoros talaje (Guérin-Méneville, 1849); Ornithodoros faccinii Barros-Battesti, Landulfo & Luz, 2015; Ornithodoros cavernicolous Dantas-Torres, Venzal & Labruna, 2012 and Ornithodoros rietcorreai Labruna, Nava & Venzal, 2016(GUGLIELMONE et al, 2010DANTAS-TORRES et al, 2012;BARROS-BATTESTI et al, 2013WOLF et al, 2016;LABRUNA et al, 2016).

In this paper, the authors report ticks parasitizing bats from the Serra das Almas Natural Reserve (RPPN) located in the municipality of Crateús, state of Ceará, in the semiarid Caatinga biome of northeastern Brazil. The study was carried out during nine nights in the dry season (July 2012) and 10 nights in the rainy season (February 2013). Only bats of the Phyllostomidae and Mormoopidae families were parasitized by ticks. The species Artibeus planirostris and Carolia perspicillata were the most parasitized. A total of 409 larvae were collected and classified into three genera: Antricola (n = 1), Nothoaspis (n = 1) and Ornithodoros (n = 407). Four species were morphologically identified as Nothoaspis amazoniensis, Ornithodoros cavernicolous, Ornithodoros fonsecai, Ornithodoros hasei, and Ornithodoros marinkellei. Ornithodoros hasei was the most common tick associated with bats in the current study. The present study expand the distributional ranges of at least three soft ticks into the Caatinga biome, and highlight an unexpected richness of argasid ticks inhabiting this arid ecosystem.

Recently, the importance of wild-living rodents for maintenance of pathogens of the family Anaplasmataceae in the environment was investigated. These mammals play a role as reservoirs for these pathogens and act as hosts for the immature stages of tick vectors. The aim of the present study was to investigate the prevalence of Ehrlichia sp. and Anaplasma sp. in 24 specimens of Azara's agouti (Dasyprocta azarae) that had been trapped in the Itapiracó Environmental Reserve, in São Luís, Maranhão, northeastern Brazil, using molecular methods. Four animals (16.7%) were positive for Ehrlichia spp. in nested PCR assays based on the 16S rRNA gene. In a phylogenetic analysis based on the 16S rRNA gene, using the maximum likelihood method and the GTRGAMMA+I evolutionary model, Ehrlichia sp. genotypes detected in Azara's agoutis were found to be closely related to E. canis and to genotypes relating to E. canis that had previously been detected in free-living animals in Brazil. The present work showed the first molecular detection of Ehrlichia sp. in Azara's agoutis in Brazil.
