Consumption of ready-to-eat (RTE) vegetables is quick, easy and healthy, especially when eaten without cooking. However, they might be a source of foodborne pathogenic microorganisms. The objective of this study was to evaluate the microbiological and parasitological contamination of fresh RTE vegetables produced in agroindustries in the Federal District of Brazil (FD), and to correlate contamination with good ...
We report an Acanthamoeba keratitis case associated with the use of contact lens in a 28-year-old female from Brasília, Brazil. Samples from corneal scraping and contact lens case were used for culture establishment, PCR amplification, and partial sequencing (fragments of ~400kb) of small subunit rDNA; both culture and PCR were positive. The sequence analyses of the cornea and of isolates from the contact lens ...

Background: knowledge on synanthropic phlebotomines and their natural infection by Leishmania is necessary for the identification of potential areas for leishmaniasis occurrence. Objective: to analyse the occurrence of Phlebotominae in gallery forests and household units (HUs) in the city of Palmas and to determine the rate of natural infection by trypanosomatids. Methods: gallery forests and adjacent household...
This study updates the geographic distributions of phlebotomine species in Central-West Brazil and analyses the climatic factors associated with their occurrence. The data were obtained from the entomology services of the state departments of health in Central-West Brazil, scientific collections and a literature review of articles from 1962-2014. Ecological niche models were produced for sandfly species with mo...
Psammolestes tertius Lent & 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 s...
Aproximadamente 90% da população no noroeste da Amazônia é composta de grupos indígenas e o acesso deles aos serviços de saúde ainda é um desafio. O objetivo deste estudo foi determinar a frequência de parasitos em dois grupos indígenas (Baré e Baniwa) no noroeste da Amazônia. Amostras de fezes de 270 indivíduos (199 Baniwa e 71 Baré) foram analisadas pelos métodos de Richie e sedimentação espontânea. Foram det...
INTRODUÇÃO: Populações de Triatoma sordida Stål, 1859 foram investigadas quanto à suscetibilidade à deltametrina. MÉTODOS: Análise por meio de bioensaios por aplicação tópica em 11 populações de T. sordida procedentes dos Estados de Goiás, Mato Grosso e Mato Grosso do Sul. RESULTADOS: As estimativas de DL50 e RR50 demonstraram elevados níveis de suscetibilidade (DL50 < 1 e RR50 < 2). Entretanto, as análises do ...
INTRODUÇÃO: As espécies de triatomíneos registradas pela vigilância entomológica da doença de Chagas no Distrito Federal (DF), Brasil, são Panstrongylus megistus, Panstrongylus geniculatus, Panstrongylus diasi, Rhodnius neglectus, Triatoma pseudomaculata e Triatoma sordida. Nosso objetivo foi analisar a ocorrência espacial e temporal das espécies de triatomíneos coletadas no DF, assim como seus índices de infec...
INTRODUCTION: The present study shows a descriptive analysis of triatomine occurrence and its natural Trypanosoma infection rates in the state of Pernambuco, Brazil, between 2006 and 2007. METHODS: Entomological data for the species, such as specimens captured in both intra and peridomiciles and natural infection index, were obtained via domiciliary capture in 147 municipalities from 11 Regional Managements of ...
