Abstract  Background  Spotted fever is a tick-borne rickettsial disease. In Brazil, its notification to the Ministry of Health is compulsory. Since 2007, cases of spotted fever have been integrated to the Notifiable Diseases Information System, and epidemiological analyzes are part of the routines on surveillance programs.  Methods  This descriptive study updates epidemiological information on cases of spotted fever registered in Brazil between 2007 and 2015.  Results  In Brazil, 17,117 suspected cases of the disease were reported and 1,245 were confirmed in 12 states, mainly in São Paulo (550, 44.2 %) and Santa Catarina (276, 22.2 %). No geographic information was registered for 132 cases (10.6 %). Most of the infected people were men (70.9 %), mainly in...

Arthropods associated with the crown of Mauritia flexuosa (Arecaceae) palm trees in three different environments from Brazilian Cerrado
Provedor de dados: 82
Autores: Gurgel-Gonçalves,Rodrigo; Palma,Alexandre R.T.; Motta,Paulo C.; Bar,Maria E.; Cuba,Cesar A.C.
Canopy arthropods, mainly from palm trees, are little known in the Brazilian Cerrado. In order to describe the arthropod community structure associated with the crown of Mauritia flexuosa (Arecaceae), we sampled 150 palm trees in six "veredas" of the Federal District, Brazil, in wild, rural and periurban areas in the rainy season. The arthropods within abandoned bird nests, mammal refuges, leaves and organic matter were manually collected, preserved in ethanol 70% and separated by order, family, morphospecies and feeding guilds. Stem height and diameter of the palm crowns were measured and leaves and bird nests were counted. We collected 3,862 arthropods, from 15 orders, 45 families and 135 morphospecies. The most abundant orders were Coleoptera (28.6%),...

Morphometric changes of Rhodnius neglectus (Hemiptera: Reduviidae): in the transition from sylvatic to laboratory conditions
Provedor de dados: 103
Autores: Gurgel-Gonçalves,Rodrigo; Maeda,Maicon H; Ferreira,Jônatas B.C; Rosa,Aline da F; Cuba,César A.C.
In the present work, we investigated whether it is possible to detect morphometric changes in Rhodnius neglectus Lent, 1954 (a candidate vector of Chagas disease in Central Brazil) populations in the transition from sylvatic to laboratory conditions. We analyzed size and shape variation in wings of sylvatic parents and their laboratory descendents (first, third and fifth generations) using geometric morphometric techniques. Sexual size dimorphism and shape of wings were maintained, but wing size decreased from sylvatic specimens to their laboratory generations. Size variation in R. neglectus should reflect the expected morphometric changes between sylvatic and domestic populations and can be applied to analyze the level of adaptation of R. neglectus to...

Infestation of thornbird nests (Passeriformes: Furnariidae) by Psammolestes tertius (Hemiptera: Reduviidae) across Brazilian Cerrado and Caatinga ecoregions
Provedor de dados: 103
Autores: Gurgel-Gonçalves,Rodrigo; Cuba,César Augusto Cuba.
Psammolestes tertius Lent &amp;amp; Jurberg, 1965 is a sylvatic triatomine bug species that occurs in thornbird nests in Brazil. We studied infestation of 527 nests of Phacellodomus rufifrons Wied, 1821 and Phacellodomus ruber Vieillot, 1817 by P. tertius in eight Brazilian states across the Cerrado and Caatinga ecoregions. Psammolestes tertius occurred in 44% of the nests, mainly in those of P. ruber. Overall, 3,261 specimens (52% nymphs) were captured, with an average of 14 bugs per infested nest (range 1-75). While P. tertius occurrence and age structure (percentage of nymphs) were similar in Cerrado and Caatinga nests, infestation intensity (bugs/infested nest) was higher in the Cerrado. Last-stage nymphs and adults were predominant in P. tertius...

Variação morfológica de pegadas de roedores arborícolas e cursoriais do Cerrado
Provedor de dados: 104
Autores: Camargo,Nícholas F. de; Gurgel-Gonçalves,Rodrigo; Palma,Alexandre R. T.
Considerando que os roedores possuem diversas formas de locomoção, o presente estudo apresenta e discute variações na forma das pegadas anteriores e posteriores de sete espécies [Akodon cursor (Winge, 1887), Necromys lasiurus (Lund, 1840), Oecomys bicolor (Tomes, 1860), Oecomys concolor (Wagner, 1845), Oligoryzomys nigripes (Olfers, 1818), Hylaeamys megacephalus (Fischer, 1814) e Rhipidomys macrurus (Gervais, 1855)], utilizando técnicas de morfometria geométrica e análises discriminantes. As variáveis de forma das pegadas foram relacionadas com a topologia filogenética e os modos de locomoção das espécies para verificar a influência de fatores históricos e ecológicos na morfologia das pegadas. A forma das pegadas dos roedores arborícolas (curtas e largas)...

Estrutura de populações de Rhodnius neglectus Lent e Psammolestes tertius Lent &amp;amp; Jurberg (Hemiptera, Reduviidae) em ninhos de pássaros (Furnariidae) presentes na palmeira Mauritia flexuosa no Distrito Federal, Brasil
Provedor de dados: 104
Autores: Gurgel-Gonçalves,Rodrigo; Cuba,César A. C.
Rhodnius neglectus Lent, 1954 {Rn}e Psammolestes tertius Lent &amp;amp; Jurberg, 1965 {Pt} são triatomíneos que ocorrem em ninhos de aves, principalmente da família Furnariidae. O ciclo biológico dessas espécies é conhecido em condições de laboratório, sendo poucos estudos em ecótopos silvestres. Para analisar a infestação e estrutura de populações de Rn e Pt em ninhos de aves presentes na palmeira Mauritia flexuosa Linnaeus, em duas estações climáticas do Brasil Central, foram amostradas 41 palmeiras com evidências de nidificação de Phacellodomus ruber Vieillot, 1817 (22 na estação chuvosa e 19 na estação seca) em quatro áreas do Distrito Federal. Os insetos foram capturados usando-se coleta manual na copa da palmeira, identificados morfologicamente,...

Morphometric identification of small mammal footprints from ink tracking tunnels in the Brazilian Cerrado
Provedor de dados: 104
Autores: Palma,Alexandre R. T.; Gurgel-Gonçalves,Rodrigo.
An alternative method for identifying and inventorying rodents and marsupials inhabiting forests and grasslands of Brazilian Cerrado is presented and discussed. Ink tracking tunnels were designed according to the size of target species and used to build a reference collection of small mammal footprints composed of 1408 footprints belonging to 251 individuals from 30 species (21 rodents and nine marsupials). Sherman traps and ink tracking tunnels were used to conduct inventories in gallery forests. Footprints obtained in ink tracking tunnels were digitalized and compared with those in reference collection using Discriminant Analysis (DFA). DFA allowed good footprint differentiation, even among congeneric species. In DFA analysis, the first two axis were...
