The Triatoma brasiliensis complex is a monophyletic group, comprising three species, one of which includes two subspecific taxa, distributed across 12 Brazilian states, in the caatinga and cerrado biomes. Members are diverse terms epidemiological importance, morphology, biology, ecology, genetics. b. most disease-relevant member epidemiology, extensive distribution, broad feeding preferences, ecological high rates infection with Trypanosoma cruzi; consequently, it considered principal vector...

To clarify the epidemiologic importance of Triatoma brasiliensis, most important Chagas disease vector in Northeastern Brazil, capture data related to this species, its distribution, index, and percentages natural infection by Trypanosoma cruzi were examined 12 different Brazilian states. The National Health Foundation collected these from 1993 1999, a period during which total 1,591,280 triatomines (21 species) captured domiciles within geographic range T. brasiliensis. Of total, 422,965...

We present here a multisource approach that takes advantage of several disciplines to address taxonomic issue. A triatomine related Rhodnius robustus Larrousse, 1927 was recently found in the state Rondônia, Brazil. The name montenegrensis n. sp. is suggested because it municipality Monte Negro. main differences between these two species can be detected female and male genitalia, but there are also noticeable their eggs. Molecular analysis using PCR-RFLP technique Bayesian inferences based...

Industrial toxin and drugs have been associated with non-alcoholic fatty liver disease (NAFLD); in these cases, the has termed toxicant-associated steatohepatitis (TASH).This study hypothesizes that use of anabolic-androgenic steroids (AAS) could also be a risk factor to TASH or better (TAFLD) development.Case-control including 180 non-competitive recreational male bodybuilders from August/2007 March/2009. Ninety-five had history intramuscular AAS (cases; G1) 85 were non-users (controls;...

We used an individual-based molecular multisource approach to assess the epidemiological importance of Triatoma brasiliensis collected in distinct sites and ecotopes Rio Grande do Norte State, Brazil. In semi-arid zones Brazil, this blood sucking bug is most important vector Trypanosoma cruzi--the parasite that causes Chagas disease. First, cytochrome b (cytb) microsatellite markers were for inferences on genetic structure five populations (108 bugs). Second, we determined natural T. cruzi...

In Latin America, the bloodsucking bugs Triatominae are vectors of Trypanosoma cruzi, parasite that causes Chagas disease. Chemical elimination programs have been launched to control disease vectors. However, persists because native from sylvatic habitats able (re)colonize houses-a process called domiciliation. Triatoma brasiliensis is one example. Because chemosensory system allows insects interact with their environment and plays a key role in insect adaption, we conducted descriptive...

Chagas disease persists as one of the most important, and yet neglected, diseases in world, several changes its epidemiological aspects have been recorded since discovery. Currently, some relevant are related to: (i) reduction incidence endemic due to control important vectors, Triatoma infestans Rhodnius prolixus, many countries; (ii) migration human populations spreading cases throughout from non-endemic areas, transforming into a global threat; (iii) new acute deaths caused by oral...

O infarto agudo do miocárdio (IAM) é uma das principais causas de mortalidade global, destacando-se como relevante questão saúde pública. Portanto, este estudo teve o objetivo identificar perfil sociodemográfico e epidemiológico óbitos por Infarto Agudo Miocárdio no estado Ceará dos anos 2014 a 2023. Trata-se um retrospectivo descritivo, com abordagem quantitativa, que examinou variáveis faixa etária, sexo, cor/raça, civil local ocorrência óbitos. A IAM aumentou progressivamente idade, sendo...

Abstract Background Triatoma brasiliensis is the primary vector of Chagas disease in Brazil's semi-arid regions, exhibiting adaptability to various environments, including domestic and peridomestic. Despite its significance, comprehensive genomic data for this subspecies remain limited. Methods We assembled complete mitochondrial genome T. b. using a combination Illumina Sanger sequencing technologies, latter being necessary obtain control region with eight primers designed study. The...

The phylogenetic position of Triatoma sherlocki within triatomines group was inferred by analyzing mtDNA fragments Cyt B and 16S ribosomal RNA using maximum parsimony Bayesian analysis. Despite being differentiated from members the T. brasiliensis complex on morphologic grounds, molecular analysis suggests is a member this complex; moreover, it placed as sister species melanica . These suggestions were supported robust credibility rates. Hence, we show evidence for paraphyletic “ complex,”...

Multiple fragments of mitochondrial DNA genes (cytochrome b, cytochrome oxidase I, and 16S rDNA) were used to evaluate the phylogenetic relationships among Triatoma melanocephala, tibiamaculata, vitticeps, other members brasiliensis subcomplex under a Bayesian framework maximum parsimony criterion. With addition new sequences T. tibiamaculata juazeirensis, melanica newly sequenced three first sylvatic species, strongly recovered into clade separate from with remaining species South America,...

In the subfamily Triatominae, Triatoma exhibits largest number of species, which are arranged in complexes. For T.brasiliensis species complex, recent investigations based on results geometric morphometrics combined with phylogeny have provided evidence that it should be composed seven species: T.brasiliensis, T.bahiensis, T.juazeirensis, T.lenti, T.melanica, T.petrocchiae, and T.sherlocki, is divided two subspecies: T.b.brasiliensis T.b.macromelasoma. A taxonomic key presented to identify...

Innovative approaches used to combat Chagas disease transmission tend combine a set of comprehensive efforts understand the ecology local vectors. In this work we identified molecularly blood meal 181 Triatoma brasiliensis, distributed in 18 populations (8 sylvatic and 10 peridomestic), which were collected across range 240 km (East-West) 95 (North-South) semi-arid region northeastern, Brazil. We vertebrate mitochondrial gene (cytochrome B) sequencing applied DNA isolated from bug midgut...

The presence of Triatoma rubrovaria in Brazil has only been confirmed the States Paraná and Rio Grande do Sul (RS), where it is found naturally infected with Trypanosoma cruzi. In wild environment occurs rocky habitats an eclectic diet, feeding from cockroaches, reptiles mammals. Data Chagas Disease Control Program obtained by Fundação Nacional de Saúde, between 1975 1997, indicate a growing domiciliary peridomiciliary invasion T. RS, become most frequently Triatominae species captured this...

Abstract. Searches for Chagas disease vectors were performed at the type locality from which Triatoma sherlocki Papa et al. (Hemiptera: Reduviidae: Triatominae) was described in municipality of Gentio do Ouro, state Bahia, Brazil, and a small artisan quarry‐mining community ∼13 km distant remote area same municipality. The latter site represents new record this species. Adults, nymphs exuviae T. found 21% human dwellings, indicating that species is process domiciliation. Prevalence...

Triatoma brasiliensis is considered one of the most important Chagas disease vectors being a widespread species in semiarid areas northeastern Brazil. The displays distinct chromatic patterns cuticle different localities. Four populations were analyzed this study: 1-Caicó, Rio Grande do Norte, it will be called population; 2-Espinosa, Minas Gerais, melanica 3-Petrolina, Pernambuco, macromelasoma population, and 4-Juazeiro, Bahia, darker overall coloration, Juazeiro population. In order to...

The Triatoma brasiliensis genetic structure was analyzed using the Cyt B gene in different geographic locations and ecotopes after a short long period insecticide treatment. Four localities (16-40 km apart) state of Paraíba, Brazil, were sampled. Analysis molecular variance (AMOVA) showed that grouping populations according to location or ecotope resulted higher among within groups (Phi(SC) ranging from 0.15 0.17) than (Phi(CT) 0.04 0.07). percentage variation reduced increased = 0.08,...
