Chagas' disease in the Amazon basin IV. Host records of Trypanosoma cruzi zymodemes in the states of Amazonas and Rondonia, Brazil.

Abstract: Of 151 Trypanosoma cruzi stocks from 117 different individual hosts collected in the states of Amazonas and Rondonia, 147 from 113 hosts were identified as zymodeme 1 (Z1). These included T. cruzi stocks from three marsupial species, two rodent species and three triatomine species although most were from the common opossum, Didelphis marsupialis. One T. cruzi stock from Rhodnius robustus was identified as Z1 with a Z3 PGM character, one from Sciurus sp. as Z3 and two from Monodelphis brevicaudata and Panstrongylus geniculatus as Z3 with a Z1 ASAT character. The ways in which stocks were isolated and grown up in vitro did not influence isozyme profile. These results support earlier evidence from Para State that Z2 is absent from the Amazon basin and that the distribution of T. cruzi zymodemes in this region is quite different to that in endemic areas on the south of the continent.

The ocurrence of dengue and weather changes in Brazil: A systematic review

Abstract: Introduction: Dengue is configures in recent decades as an important cause of morbidity and mortality in Brazil and around the world reaching the tropical and subtropical areas. Objective: To review the scientific literature on the occurrence of dengue in Brazil and its relationship with meteorological variables. Method: A systematic review of studies published in databases (SciELO, PubMed, MEDLINE, Lilacs) using descriptors related to weather variations and dengue fever in Brazil, published between 1991 to 2010. It was selected 31 articles that had the study area nationwide. Results: Most epidemiological studies use ecological design, the studies make use of entomological trapping, are common also series of studies of the disease and spatial analysis. It is evident relationship between dengue incidence with temperature and rainfall, the association is more significant from the second to fourth months of the year. Comparative studies of drought and rain show seasonal behavior of the disease. There are difficulties in establishing unique pattern of seasonality of disease incidence and weather variables for the country. Conclusion: Dengue is strongly related to meteorological variables. The seasonal variation in temperature and rainfall influences the dynamics of the vector and the incidence of the disease throughout the country, regardless of the climate category.

Plantas medicinais usadas para a saúde bucal pela comunidade do bairro Santa Cruz, Chapada dos Guimarães, MT, Brasil

Abstract: Em Mato Grosso, populacoes tradicionais recorrem ao uso de especies vegetais como alternativa terapeutica. Na cidade de Chapada dos Guimaraes, o bairro Santa Cruz se destaca por abrigar familias nascidas em areas urbanas ou rurais que conservam esses conhecimentos transmitidos por geracoes. Esta pesquisa tem como objetivo o levantamento das plantas medicinais utilizadas pela comunidade local, indicacoes terapeuticas, preparos e modos de uso visando a manutencao e recuperacao da saude bucal. Foram entrevistados 40 residentes, atraves de abordagem qualitativa, usando entrevista semi-estruturada. As especies catalogadas foram depositadas para identificacao no UFMT/Herbario Central. Foram citadas 87 especies pertencentes a 48 familias utilizadas na saude bucal, encontradas no bioma Cerrado ou cultivadas nas residencias. Conforme as afeccoes bucais citadas, as especies utilizadas sao: para erupcao dentaria: camomila (Matricaria chamomilla L.); candidiases, estomatites, gengivites e afta: acafrao (Crocus sativus L.); dor de dente: arnica-da-serra (Brickelia brasiliensis (Spreng.) Robinson). A folha foi a parte da planta mais usada e o cha, por decoccao, modo de preparo mais comum. Pessoas idosas, lideres comunitarios, parteiras e benzedeiras entrevistados apresentaram um maior conhecimento sobre o assunto. Constatou-se que a comunidade utiliza especies vegetais, nativas do cerrado ou exoticas, com finalidade terapeutica para manutencao e recuperacao da saude bucal, sendo uma alternativa tradicional, economica e atuante.
