Ocorrência de Panstrongylus guentheri Berg (Hemiptera: Reduviidae) no Mato Grosso do Sul

Relata-se a primeira ocorrência de Panstrongylus guentheri Berg no Brasil. Essa espécie, até então, havia sido observada somente na Argentina, Paraguai, Bolívia e Uruguai. Desta feita, amplia-se a distribuição geográfica desse Triatominae por meio de dois exemplares capturados nos municípios de Bodoquena e Itaporã, ambos no Mato Grosso do Sul. Esses exemplares estavam em ambiente intradomiciliar

Microsatellite Polymorphisms in Cassava Landraces from the Cerrado Biome, Mato Grosso do Sul, Brazil

Using nine microsatellite loci, we investigated genetic structure and diversity in 83 Brazilian cassava accessions, including several landraces, in the Cerrado biome in Mato Grosso do Sul, Brazil. All nine loci were polymorphic, averaging 6.00 alleles per locus. Treating each of seven municipalities as a cassava group or population, they averaged 3.5 alleles per locus, with 97% polymorphic loci, high values for observed heterozygosity (0.32) and gene diversity (0.56). Total genetic variability was high (0.668), and most of this genetic variability was concentrated within municipalities (0.577). Cluster and structure analyses divided accessions into two major clusters or populations (K = 2). Also, a significant genetic versus geographic correlation was found (r = 0.4567; P < 0.0260). Migratory routes in the Cerrado are considered main contributors to the region`s high cassava diversity and spatial genetic structure, amplifying interactions between traditional farmers and the evolutionary dynamics of this crop.

Motivations for the establishment of PNHRs and analysis of the incentives for their creation and management in Mato Grosso do Sul

The development of efficient programs of incentive to voluntary conservation in private lands require an extensive knowledge on the motivations of land owners for conservation and their degree of acceptance on the benefits offered. Thus, this paper intended to evaluate the motivations for the establishment of PNHRs, the difficulties faced by their recognition and the incentives received for their establishment and management in Mato Grosso do Sul, and also to discuss some possibilities of widening the benefits offered. To this end, people responsible for 34 PNHRs were interviewed between March/2008 and March/2009. The results show that conservation is among the main reasons for the creation of these areas, in spite of economical and personal factors also being mentioned. The slowness and the red tape during the process of recognition were also emphasized as problems; on the other hand, several PNHRs received or receive support for their creation or management. Finally, some considerations are made on the benefits offered to owners of PNHRs and their possibilities of widening throughout the state.

Floristic composition of seasonal riparian forests in Mato Grosso do Sul State, Brazil

(Floristic composition of seasonal riparian forests in Mato Grosso do Sit] State, Brazil). This Study aimed to characterize the floristic composition in two stretches of seasonal semideciduous forest associated with the Formoso River, Bonito, Mato Grosso do Sul State, and in three stretches of seasonal deciduous and semideciduous forests associated with the Salobra, Salobrinha and Perdido rivers in Bodoquena Plateau National Park (76,481 ha) - the only Federal Conservation unit with Integral Protection in the state of Mato Grosso do Sul. The floristic survey was carried out monthly from October/2004 to March/2006, where flowering and fruiting phanerogams were collected by the method of evaluation time. The floristic survey resulted in 56 families, 184 genera and 307 species. Of the total number of species, 68% were trees, 17% shrubs, 14% lianas and only 1% palms. The Fabaceae family (Leguminosae), represented by 51 (16.6%) species, was the most species-rich. These results increase our knowledge of the Mato Grosso do Sul flora and its geographic distribution, thus emphasizing the need for conservation of these riparian forests and providing subsidies for restoration projects of the degraded areas around the conservation unit and permanent protection areas (APPs) of regional rivers.

Serological Evidence of Paracoccidioides brasiliensis Infection in Chickens from Parana and Mato Grosso do Sul States, Brazil

The objective of this study was to detect antibodies against Paracoccidioides brasiliensis in free-range and caged chickens Gallus domesticus. Initially, the humoral immune response of two chickens immunized with P. brasiliensis was evaluated. Both animals showed the production of antibodies to gp43, the major P. brasiliensis antigen. The seroepidemiological survey was conducted in chickens from the Pantanal region in Mato Grosso do Sul State (free-range n = 40) and from northern region of Parana State (free-range n = 100, caged n = 43). The serum samples were analyzed by indirect ELISA using gp43 as antigen. The positivity observed in free-range chickens from Mato Grosso do Sul (55%) was significantly higher (P = 0.0001) than in free-range chickens from Parana State (16%). In contrast to the free-range chickens, no positivity was observed in the caged chickens (P = 0.003). This is the first report showing serological evidence of P. brasiliensis infection in chickens. The results suggest that free-range chickens are more frequently infected by P. brasiliensis, probably due to the constant contact with soil than caged chickens and could be useful as epidemiological markers of paracoccidioidomycosis.

Species-specific identification of Leishmania in naturally infected sand flies captured in Mato Grosso do Sul State, Brazil

An increase in cutaneous and visceral leishmaniasis cases has been reported in recent years in the state of Mato Grosso do Sul, Brazil, and little is known to date about their etiological agents. An investigation into natural Leishmania infection of sand flies captured in this state between December 2003 and August 2004 was carried out. Mini-exon sequences were used as targets to identify Leishmania, and an RFLP technique was employed for those identified as belonging to the Viannia subgenus. Calculation of the minimal infection rate (MR) revealed that 1.6% of sand flies captured in the forest, peridomicile and intradomicile were positive. Six species were found to be infected by Leishmania (V.) braziliensis. Interestingly, two of the six species. Lutzomyia longipalpis and Nyssomyia whitmani, were captured in anthropic environments. The findings of this study constitute a useful tool for planning control measures against this disease in the State of Mato Grosso do Sul. (C) 2010 Elsevier B.V. All rights reserved.

Observations on the feeding habits of Lutzomyia longipalpis (Lutz & Neiva, 1912) (Diptera: Psychodidae: Phlebotominae) in Campo Grande, an endemic area of visceral leishmaniasis in Mato Grosso do Sul, Brazil

Sand flies were captured weekly with CDC light traps from December 2003 to November 2005 in three areas of Campo Grande, in the Brazilian state of Mato Grosso do Sul. These areas incorporated two patches of remnant forest and five houses. The blood meals of engorged female sand flies were identified using the avidin-biotin system of immunoenzymatic ELISA capture. Most (327/355) of the females analysed were Lutzomyia longipalpis, of which 66.4% reacted with human blood, 64.8% with that of birds and 8.9% with that of dogs. Females that had taken human blood predominated in the residential areas and two forest patches. The following combinations of blood were also detected for L. longipalpis in some of the samples analysed: bird + human (43.4%), bird + human + dog (6.1%). The combination bird + human + dog + pig was also found for Nyssomyia whitmani. Dogs and pigs appear to have little attractiveness for L. longipalpis. The results obtained demonstrate the eclecticism and high anthropophily of L. longipalpis and raise new questions with regard to the importance of dogs in VL epidemiology and the possible role of man as a source of infection for sand flies.

Seasonal variation of Lutzomyia longipalpis (Lutz & neiva, 1912) (Diptera : Psychodidae : Phlebotominae) in endemic area of visceral leishmaniasis, Campo Grande, state of Mato Grosso do Sul, Brazil

The seasonal distribution of Lutzomyia longipalpis was studied in two forested and five domiciliary areas of the urban area of Campo Grande; MS, from December 2003 to November 2005. Weekly captures were carried out with CDC light traps positioned on ground and in the canopy inside a residual forest and on the edge (ground) of a woodland and in at least one of the following ecotopes in peridomiciles-a cultivated area, a chicken coop, a pigsty, a kennel, a goat and sheep shelter and an intradomicile. A total of 9519 sand flies were collected, 2666 during the first year and 6853 during the second. L. longipalpis was found throughout the 2-year period, presenting smaller peaks at intervals of 2-3 months and two greater peaks, the first in February and the second in April 2005, soon after periods of heavy rain. Only In one of the woodlands was a significant negative correlation (p < 0.05) between the number of insects and temperature during the first year and the climatic factors (temperature, RHA and rain) was observed. In the domiciliary areas in four domiciles some positive correlations (p < 0.05) occurred in relation to one or more climatic factors; however, the species shows a clear tendency to greater frequency (72%) in the rainy season than in the dry (28%). Thus, we recommend an intensification of the VL control measures applied in Campo Grande, MS, during the rainy season with a view to reducing the risk of the transmission of the disease.

THE RIO APA CRATON IN MATO GROSSO DO SUL (BRAZIL) AND NORTHERN PARAGUAY: GEOCHRONOLOGICAL EVOLUTION, CORRELATIONS AND TECTONIC IMPLICATIONS FOR RODINIA AND GONDWANA

The Rio Apa cratonic fragment crops out in Mato Grosso do Sul State of Brazil and in northeastern Paraguay. It comprises Paleo-Mesoproterozoic medium grade metamorphic rocks, intruded by granitic rocks, and is covered by the Neoproterozoic deposits of the Corumbi and Itapocurni Groups. Eastward it is bound by the southern portion of the Paraguay belt. In this work, more than 100 isotopic determinations, including U-Pb SHRIMP zircon ages, Rb-Sr and Sm-Nd whole-rock determinations, as well as K-Ar and Ar-Ar mineral ages, were reassessed in order to obtain a complete picture of its regional geological history. The tectonic evolution of the Rio Apa Craton starts with the formation of a series of magmatic arc complexes. The oldest U-Pb SHRIMP zircon age comes from a banded gneiss collected in the northern part of the region, with an age of 1950 +/- 23 Ma. The large granitic intrusion of the Alumiador Batholith yielded a U-Pb zircon age of 1839 +/- 33 Ma, and from the southeastern part of the area two orthogneisses gave zircon U-Pb ages of 1774 +/- 26 Ma and 1721 +/- 25 Ma. These may be coeval with the Alto Terere metamorphic rocks of the northeastern corner, intruded in their turn by the Baia das Garcas granitic rocks, one of them yielding a zircon U-Pb age of 1754 +/- 49 Ma. The original magmatic protoliths of these rocks involved some crustal component, as indicated by the Sm-Nd TDm model ages, between 1.9 and 2.5 Ga. Regional Sr isotopic homogenization, associated with tectonic deformation and medium-grade metamorphism occurred at approximately 1670 Ma, as suggested by Rb-Sr whole rock reference isochrons. Finally, at 1300 Ma ago, the Ar work indicates that the Rio Apa Craton was affected by widespread regional heating, when the temperature probably exceeded 350 degrees C. Geographic distribution, age and isotopic signature of the fithotectonic units suggest the existence of a major suture separating two different tectonic domains, juxtaposed at about 1670 Ma. From that time on, the unified Rio Apa continental block behaved as one coherent and stable tectonic unit. It correlates well with the SW corner of the Amazonian Craton, where the medium-grade rocks of the Juruena-Rio Negro tectonic province, with ages between 1600 and 1780 Ma, were reworked at about 1300 Ma. Looking at the largest scale, the Rio Apa Craton is probably attached to the larger Amazonian Craton, and the actual configuration of southwestern South America is possibly due to a complex arrangement of allochthonous blocks such as the Arequipa, Antofalla and Pampia, with different sizes, that may have originated as disrupted parts of either Laurentia or Amazonia, and were trapped during later collisions of these continental masses.

Análise epidemiológica das causas externas em unidades de urgência e emergência em Cuiabá/Mato Grosso

OBJETIVO: Apesar da importância das causas externas como problema de saúde pública, pouco se conhece sobre a demanda de serviços de urgência e emergência. Este estudo tem como objetivo caracterizar a morbidade por causas externas em unidades de urgência e emergência do município de Cuiabá/MT. MÉTODO: Trata-se de um estudo transversal e descritivo. Foram analisadas 3.786 vítimas de causas externas atendidas pelas cinco unidades de urgência e emergência da Secretaria Municipal de Saúde de Cuiabá/MT, no período de 1 de maio a 30 de junho de 2005. RESULTADOS: Aproximadamente 88% dos atendimentos se referiam a vítimas de acidentes, 9% corresponderam a agressões e 2% a lesões autoprovocadas. Os acidentes de transportes representaram 22% dos atendimentos, sendo os motociclistas as principais vítimas (49%); as quedas foram as causas mais freqüentes no grupo de outras causas externas de traumatismos acidentais. A prevalência em homens superou a de mulheres. A maior parte das vítimas era menor de 40 anos (79%). No entanto, a análise por tipo de causa externa apresenta resultados diferentes segundo sexo e faixa etária. Cerca da metade dos eventos ocorreu em casa e, em sua maioria, as vítimas receberam alta após o atendimento, sendo que a taxa de mortalidade foi baixa (0,4%). CONCLUSÃO: Os resultados revelam a importância da análise sistemática dos dados referentes às vítimas de acidentes e violência atendidas em unidades de urgência e emergência, como complemento às informações sobre mortalidade e morbidade hospitalar visando o monitoramento dessas causas.

Desenvolvimento de pré-escolares na educação infantil em Cuiabá, Mato Grosso, Brasil

O objetivo foi avaliar o desenvolvimento neuropsicomotor de pré-escolares na educação infantil. Estudo de corte transversal, utilizando 38 itens do teste de Denver II. Foram avaliados todos os pré-escolares com idade entre quatro e seis anos incompletos matriculados na Rede Pública Municipal de Ensino de Cuiabá, Mato Grosso, Brasil, no período de agosto 2002 a novembro 2003. Nesse período havia 960 pré-escolares matriculados em 27 creches e duas escolas públicas. Para a análise estatística foi aplicado o teste Ç2 com intervalo de 95% de confiança e ± = 5%. Para calcular os percentis da idade em que os pré-escolares passaram em cada prova foi realizada uma regressão logística. Dos 960 pré-escolares avaliados, 67% apresentaram desempenho normal, 30,2% questionável e 2,8% anormal. Em 27/38 itens avaliados, o percentual de acertos ultrapassou 90%. O desempenho alterado predominou no sexo masculino, no grupo de cinco a seis anos. O desempenho dessa população foi muito semelhante ao dos pré-escolares norte-americanos de Denver, Colorado. O melhor resultado segundo o gênero ocorreu no sexo feminino e segundo a idade no grupo de quatro anos.

Acidentes de transporte em Cuiabá, Mato Grosso: morbi-mortalidade

Os acidentes de trânsito continuam a se constituir em um importante problema de saúde pública no Brasil. Objetivo : Analisar as características dos acidentes de transporte terrestre e suas vítimas no município de Cuiabá. Método: Para o estudo da mortalidade foram obtidos dados do Sistema de Informações sobre Mortalidade /Ministério da Saúde, disponíveis em CD-ROM referente aos anos de 1980-2005; para o de morbidade hospitalar foram utilizados os dados Sistemas de Informações Hospitalares no período de 1998-2006 e para o estudo da demanda das unidades de urgência e emergência foi utilizado um banco de dados construído especialmente para esse fim, referente aos meses de maio a junho de 2005. Adotaram-se os conceitos definições estabelecidos na Classificação Internacional de Doenças 10: acidentes de transporte (categ. V01-V99) e acidente de transporte terrestre (V01-V89). Resultados: Em todas as análises, as taxas de mortalidade/morbidade hospitalar se expressaram com valores maiores que a média brasileira. Apesar de apresentar aspectos distintos entre mortalidade, morbidade hospitalar e morbidade da demanda de unidades de urgência e emergência, destacam-se como principais vítimas os jovens do sexo masculino; a vítima qualificada como "ocupante" predomina nos acidentes fatais e os "motociclistas", nos não fatais.Conclusão: este estudo revela que Cuiabá é uma área onde os acidentes de transporte terrestre devem ser tratados como prioridade devido à sua magnitude, seja na mortalidade ou morbidade, trazendo subsídios para o seu enfrentamento

Diferenciais de cárie dentária entre os índios Xavante de Mato Grosso, Brasil

O objetivo do estudo foi avaliar níveis de experiência de cárie entre subgrupos Xavante que vivem em diferentes Terras Indígenas (T.I.) no Estado de Mato Grosso, Brasil, a fim de investigar a presença de desigualdades no interior de uma mesma etnia indígena. Os dados foram coletados através de um censo de saúde bucal realizados em 2004. Das sete T.I. Xavante existentes, foram investigadas quatro (Pimentel Barbosa, Sangradouro, Areões e Marechal Rondon), nas quais foram selecionadas a maior aldeia de cada. Foram adotados os critérios preconizados pela Organização Mundial da Saúde, e utilizado o índice CPOS. Para mensurar as diferenças entre as T.I. foi estimada a razão de prevalência (RP) por meio de análise de regressão de Poisson, efetuada na faixa etária entre 6 e 34 anos para cada sexo, incluindo a idade como covariável. Nesta faixa etária, as perdas variaram entre 26 a 30 por cento. Pimentel Barbosa foi considerada como referência para comparações por apresentar menor prevalência de cárie em todas as faixas etárias analisadas. A maior disparidade foi notada entre as T.I. Pimentel Barbosa e Sangradouro, tanto em homens (RP 2,68- IC95 por cento 2,41 a 2,97) como em mulheres (RP 2,03- IC95 por cento 1,85 a 2,23). A RP do componente obturado em Areões e Marechal Rondon (diferença relativa a Pimentel Barbosa) é muito pequena em relação à carga de doença total nestas T.I., indicando menor presença de serviço odontológico restaurador. Conclui-se que a transição em saúde bucal não é homogênea entre os Xavante e que as diferenças podem estar associadas a particularidades do processo histórico de interação com a sociedade não-indígena (Continua) (Continuação) Determinantes locais e regionais, incluindo fatores demográficos, características econômicas e sócio-culturais específicas, acesso e utilização de serviços de saúde, podem ter determinado as desigualdades de ataque de cárie observadas entre os Xavante
