Domestic, peridomestic and wild hosts in the transmission of Trypanosoma cruzi in the Caatinga area colonised by Triatoma brasiliensis
Acidentes causados por aranhas e escorpiões no Estado do Ceará, Nordeste do Brasil: casos subnotificados e superestimados baseados na distribuição geográfica das espécies
The accidents caused by arachnids have increased its frequency along the years and the majority of accidents reports do not contain species identification, contributing to underreporting of data. In Ceará state, specific information about accidents with full notifications or accident description are scarce. In this present study, data about accidents involving spiders and scorpions in Ceará state from 2010 to 2015 period were correlated with geographic distribution based on data from main Brazilian scientific collections of arachnids. An increased number of accidents caused by spiders and scorpions was observed, mainly in 2013 for scorpions, and a constant number of municipalities reported scorpionic accidents to this period. According to Sistema de Informação de Agravos de Notificação - SINAN, in Ceará state, many cases were credited to Phoneutria sp., Loxosceles sp., and Latrodectus sp., whoever this occurrence is not correlated with their geographic distribution supported on arachnid collections data. Therefore, knowledge on species geographic distribution with public health significance combined with properly notified records can contribute to reduction of accidents numbers and development of politics aimed to public health.A frequência dos acidentes causados por aracnídeos tem crescido ao longo dos anos e a maioria dos acidentes reportados não apresenta identificação das espécies causadoras, contribuindo assim para a subnotificação dos dados. No Estado do Ceará, informações específicas sobre acidentes com notificações completas ou descrição dos acidentes são escassos. No presente trabalho, os dados sobre acidentes com aranhas e escorpiões no Estado do Ceará do período de 2010 a 2015 foram confrontados com a distribuição geográfica baseada em dados existentes nas principais coleções científicas brasileiras de aracnídeos. Foi observado um aumento do número de acidentes causados por aranhas e escorpiões, principalmente em 2013 para escorpiões e um constante número de municípios reportaram acidentes escorpiônicos para o período. De acordo com o Sistema de Informação de Agravos de Notificação - SINAN, no Estado do Ceará, muitos casos foram atribuídos a Phoneutria sp., Loxosceles sp. e Latrodectus sp., contudo essa ocorrência não está correlacionada com sua distribuição geográfica existente nas coleções de aracnídeos. Desse modo, o conhecimento da distribuição geográfica das espécies de interesse em saúde combinados com registros devidamente notificados podem contribuir para redução dos números de acidentes e para o desenvolvimento de políticas voltadas para saúde pública
Escorpiones del estado de Ceará, Brasil: distribución y comentarios ecológicos
Scorpions are venomous synanthropic arachnids, in 2019 they were responsible for more than 37000 cases of envenomation in the state of Ceará, Northeastern Brazil. To update the knowledge about the scorpiofauna in Ceará, a distribution list of scorpions collected/received by municipal agents of the Health Surveillance Service was performed in 165 municipalities (89%) of Ceará (2018 – 2019) and deposited in the Dr. Thomaz Corrêa Aragão Entomology Laboratory scientific collection, including species distribution maps and ecological data. This study included a total of 999 scorpions from two families (Buthidae and Bothriuridae) and eleven species. The most abundant species were: Tityus stigmurus (40.1%), Jaguajir rochae (37.2%), Bothriurus asper (8.3%) and Bothriurus rochai (6.7%), mainly inhabiting municipalities in the Caatinga biome. The first record of Tityus confluens and Tityus maranhensis in the Sobral mesoregion is herein presented, expanding the distribution of these species in Brazil.Los escorpiones son arácnidos sinantrópicos venenosos; durante el año 2019 fueron responsables de más de 37000 casos de envenenamiento en el estado de Ceará, noreste de Brasil. Para actualizar el conocimiento sobre la escorpiónofauna en Ceará, se realizó una lista de distribución de escorpiones recolectados / recibidos em las agencias municipales del Servicio de Vigilancia de Salud de 165 municipios (89%) de Ceará (2018 – 2019), y depositados en la colección científica de Entomología del laboratorio Dr. Thomaz Corrêa Aragão, junto con mapas de distribución de especies y datos ecológicos. Este estudio incluyó un total de 999 escorpiones pertenecientes a dos familias (Buthidae y Bothriuridae) y once especies. Entre ellos, los más abundantes fueron: Tityus stigmurus (40.1%), Jaguajir rochae (37.2%), Bothriurus asper (8.3%) y Bothriurus rochai (6.7%), que habitan principalmente municipios en el bioma Caatinga. Aquí se presenta el primer registro de Tityus confluens y Tityus maranhensis en la mesorregión de Sobral, ampliando la distribución de estas especies en Brasil
Domestic, peridomestic and wild hosts in the transmission of Trypanosoma cruzi in the Caatinga area colonised by Triatoma brasiliensis
The role played by different mammal species in the maintenance of Trypanosoma cruzi is not constant and varies in time and place. This study aimed to characterise the importance of domestic, wild and peridomestic hosts in the transmission of T. cruzi in Tauá, state of Ceará, Caatinga area, Brazil, with an emphasis on those environments colonised by Triatoma brasiliensis. Direct parasitological examinations were performed on insects and mammals, serologic tests were performed on household and outdoor mammals and multiplex polymerase chain reaction was used on wild mammals. Cytochrome b was used as a food source for wild insects. The serum prevalence in dogs was 38% (20/53), while in pigs it was 6% (2/34). The percentages of the most abundantly infected wild animals were as follows: Thrichomys laurentius 74% (83/112) and Kerodon rupestris 10% (11/112). Of the 749 triatomines collected in the household research, 49.3% (369/749) were positive for T. brasiliensis, while 6.8% were infected with T. cruzi (25/369). In captured animals, T. brasiliensis shares a natural environment with T. laurentius, K. rupestris, Didelphis albiventris, Monodelphis domestica, Galea spixii, Wiedomys pyrrhorhinos, Conepatus semistriatus and Mus musculus. In animals identified via their food source, T. brasiliensis shares a natural environment with G. spixii, K. rupestris, Capra hircus, Gallus gallus, Tropidurus oreadicus and Tupinambis merianae. The high prevalence of T. cruzi in household and peridomiciliar animals reinforces the narrow relationship between the enzootic cycle and humans in environments with T. brasiliensis and characterises it as ubiquitous
