In the present study, we assessed annual screening coverage (i.e., percentage of dogs that are screened for anti-Leishmania antibodies annually) in municipality Sobral, Ceará state, Brazil. Data on number during 2008−2017 (except 2010) were obtained from Centre Zoonoses Control Sobral. The 2012−2017 was calculated. human visceral leishmaniasis (VL) cases compiled National Disease Notification System. Correlation analyses performed to assess correlation between canine and data. During...
Canine vector-borne pathogens (CVBPs) comprise a group of disease agents mainly transmitted by ticks, fleas, mosquitoes and sand flies. In this study, we assessed the presence CVBPs in an Afro-descendent community (Quilombola) northeastern, Brazil. Dog blood samples (n = 201) were collected analyzed rapid test for detection antibodies against Leishmania spp., Anaplasma Ehrlichia spp. Borrelia burgdorferi sensu lato (s.l.), antigens Dirofilaria immitis. addition, polymerase chain reactions...
Capybaras (Hydrochoerus hydrochaeris) are the largest rodents on Earth. While capybaras hosts for various tick species, there is limited information regarding tick-borne pathogens they can carry. We investigated presence of piroplasmids and Ehrlichia spp. in their associated ticks two peri-urban areas Goiás state, central-western Brazil. Blood samples collected from 23 were used to investigate stained-blood smears by PCR. Ticks identified morphologically also tested using PCR same pathogens....
Colletotrichum musae is an important cosmopolitan pathogenic fungus that causes anthracnose in banana fruit. The entire genome of C. isolate GM20 (CMM 4420), originally isolated from infected fruit Alagoas State, Brazil, was sequenced and annotated. pathogen genomic DNA on HiSeq Illumina platform. has 50,635,197 bp with G + C content 53.74% its present assembly 2763 scaffolds, harboring 13,451 putative genes average length 1626 bp. Gene prediction annotation performed by Funannotate...
The tick Amblyomma cajennense sensu stricto (A. s.s.) frequently parasitizes animals and humans in the Amazon biome, addition to being a vector of Rickettsia amblyommatis. In present study, we evaluated both population dynamics A. s.s. degraded area biome presence rickettsial organisms this population. study was carried out rural Santa Inês municipality (altitude: 24 m a.s.l.), Maranhão state, Brazil. Ticks were collected from environment for consecutive months, June 2021 May 2023. region is...
Here, we report the complete 5.3-Mb genome sequence of Xanthomonas campestris pv. viticola (CCRMXCV 80), which causes grapevine (Vitis vinifera L.) bacterial canker. Genome data will improve our understanding strain's comparative genomics and epidemiology, help to further define plant protection quarantine procedures.
Abstract Blood-feeding behavior has independently evolved in arthropods multiple times. Unlike hard ticks, soft ticks employ a rapid-feeding strategy for hematophagy, and there are comparatively limited studies on the transcriptomes of these organisms. This study investigates tick Ornithodoros hermsi , conducting histopathological examinations at bitten skin sites whole-body transcriptomic analyses across various developmental feeding stages, including larvae, 1st-nymphal, 2nd-nymphal...
Abstract Background Female ticks remain attached to their host for multiple days complete a blood meal. This prolonged feeding period is accompanied by significant increase in the tick’s size and body weight, paralleled noteworthy changes tick midgut. While midgut recognized its established role storage processing, importance extends playing crucial acquisition, survival, proliferation of pathogens. Despite this, our overall understanding biology limited. Results Our transcriptome analysis...
Abstract Ticks, as pool feeders, obtain a blood meal by lacerating small vessels and ingesting the that flows to feeding site, which triggers various host-derived responses. However, ticks face challenge of wound healing, process involving hemostasis, inflammation, cell proliferation migration, remodeling, hindering acquisition. To overcome these obstacles, tick salivary glands produce diverse array bioactive molecules. Here, we characterize ixochymostatin, an Ixodes scapularis protein...

This study was carried out from February 2020 to September 2021 in Parque Nacional das Emas (PNE), a national park located the Cerrado biome, midwestern Brazil, as well surrounding rural properties. Serum and tick samples were collected dogs, terrestrial small mammals, humans. Ticks also environment. Dogs infested with Rhipicephalus linnaei adults, whereas mammals by immature stages of Amblyomma spp., triste, dubitatum, coelebs. vegetation belonged several species genus Amblyomma, including...
