O Sistema de Gestão da Qualidade vem sendo implementado no Centro de Pesquisas René Rachou desde 2003. Este estudo investigou sua importância para os colaboradores dos laboratórios de pesquisa. Tratou-se de um estudo quantitativo, descritivo, realizado com um grupo de 113 colaboradores. Utilizou-se a diretriz Práticas de Qualidade na Pesquisa Biomédica Básica (QPBR), da Organização Mundial de Saúde. Os questionários aplicados avaliaram os parâmetros dessa diretriz utilizando a escala Likert. Biossegurança, treinamento e ética foram os fatores considerados mais importantes. Supervisão e garantia da Qualidade, registro de dados, plano de estudo, POP e arquivo obtiveram uma avaliação intermediária. A menor avaliação foi obtida para relatório, verificação de resultados, pessoal e práticas de publicação. Entender a percepção dos colaboradores permitirá o desenvolvimento de ações de melhoria, contribuindo para a construção de um programa de treinamento e estratégias de disseminação da qualidade.

Quality Management System has been implemented at the René Rachou Research Center since 2003. This study investigated its importance for collaborators (Cs) in laboratories. This was a quantitative and descriptive study performed in a group of 113 collaborators. It was based on the World Health Organization handbook: Quality Practices in Basic Biomedical Research. The questionnaires evaluated the parameters using the Likert scale. Biosafety, training and ethics were considered to be the most important parameters. Supervision and quality assurance, data recording, study plan, SOPs and file storage achieved intermediate evaluation. The lower frequency of responses was obtained for result report, result verification, personnel and publishing practices. Understanding the perception of the collaborators allows the development of improvement actions aiming the construction of a training program directing strategies for disseminating quality.

El Sistema de Gestión de la Calidad ha sido implementado en el Centro de Investigación René Rachou desde el año 2003. En este estudio se investigó la importancia de dicho sistema para los trabajadores de los laboratorios de investigación. Se realizó un estudio de tipo cuantitativo, descriptivo con un grupo de 113 trabajadores. Fueron utilizadas las guías sobre Prácticas de Calidad en Investigación Biomédica Básica (QPBR) de la Organización Mundial de la Salud. El cuestionario evalúa los parámetros de esta guía utilizando la Escala Likert. Bioseguridad, formación y ética fueron los factores considerados como los más importantes dentro del cuestionario. Supervisión y Control de calidad, registro de datos, plan de estudios, POP y el archivo obtuvieron una puntuación intermedia. La puntuación más baja fue obtenida por el informe, la verificación de resultados, el personal y las prácticas de publicación. Conocer las opiniones de los trabajadores permitirá el desarrollo de acciones para la mejora del Sistema de Gestión de la Calidad, contribuyendo al desarrollo de un programa de capacitación y de estrategias para la difusión de la calidad.

The alpha-glycerophosphate dehydrogenase (alpha-GPDH) activity in flight muscles of Panstrongylus megistus and Triatoma sordida, vectors of Chagas disease in Brazil, was studied. Both species showed higher enzymatic activities in fliers than in non-fliers insects. T. sordida exhibited a higher proportion of flier insects than P. megistus. A possible role of alpha-GPDH on triatomines flight is discussed.

Biological parameters of Triatoma brasiliensis and T. pseudomaculata that could influence the epidemiological importance of these insects as vectors of Trypanosoma cruzi were compared. The parameters studied were incubation period, interval between hatching or moulting and first feeding, number of blood meals, development time, mortality, net reproductive rate, instantaneous daily reproductive rate, time-lapse before starting feeding, duration of feeding, blood ingestion capacity, occurrence of defecation and blood ingestion velocity. Most aspects of feeding were similar for the two species, although T. pseudomaculata had a longer life cycle than T. brasiliensis producing one and two generations per year, respectively. The two species had similar instantaneous daily rates of population growth.

Among the triatomines considered as secondary in the epidemiology of Chagas disease, Rhodnius neglectus is frequently captured in artificial ecotopes, especially peridomiciliary ones, rarely producing colonies indoors. Nevertheless, the presence of breeding colonies in houses was unquestionably demonstrated in some areas of the State of Goiás, Brazil. Previous isoenzyme comparisons of this species with morphologically close triatomines, such as R. prolixus, R. robustus or R. nasutus, did not produce definitive conclusions because of doubt about the geographical origin of the R. neglectus. We present here, for the first time, the isoenzyme profile of topotypes of R. neglectus. In addition, wild caught specimens from the type locality, Uberaba (Minas Gerais, Brazil), were compared to wild caught specimens from Jaraguá (Goiás, Brazil), where R. neglectus is more frequently reported invading houses. We used isoenzyme, morphology and morphometry analysis. Neither morphological nor enzymatic differences were found between areas, but metric, size-related divergence was evidenced between them.
