Community knowledge on dengue in territories under risk in the state of São Paulo

In the last decades, the global incidence of arboviruses transmitted by the vector Aedes aegypti has increased dramatically with the increased oh human mobility and urbanization. The study of the mosquito population is of great importance for public health in countries where climatic and environmental conditions are favorable for the spread of these diseases transmitted by A. aegypti. This was a cross-sectional study that assessed causal relationships between why mosquitoes are prevalent in the region studied and socioeconomic variables, practices, knowledge, attitudes, and the effect of the cause in two regions chosen according to vulnerability (São Paulo Social Vulnerability Index). Of the 435 residents interviewed, 95% (413/435) were informed about vector control and claimed to contribute to the day-to-day sanitary practices necessary to combat it, in addition to being able to identify it. Most participants in both regions believed they were at risk, but vector control practices did not match those recorded in the survey. A correlation was found between the population's level of education and the practices observed. Despite the high levels of knowledge and the perceptions of the interviewed population about A. aegypti, the erroneous behavior of the residents persisted, thus hindering disease prevention and vector control actions, promoting the conditions conducive to the proliferation of the vector, and, consequently, increasing the risk of disease. The study indicated that one of the most effective means to control the A. aegypti vector is a society informed about preventive measures in the surveillance sectors.

Qualidade microbiológica do peixe serra (Scomberomerus brasiliensis) e do gelo utilizado na sua conservação / Microbiological quality of the fish saw (Scomberomorus brasiliensis) and the ice used for its conservation

Objetivou-se avaliar a qualidade microbiológica do peixe serra (S. brasiliensis) desembarcado no município de Raposa (MA) e do gelo utilizado na sua conservação. As amostras de gelo e de peixe serra foram submetidas às análises de determinação do Número Mais Provável (NMP) de Coliformes Totais, Termotolerantes e Escherichia coli. Para as amostras de peixe, realizou-se ainda pesquisa de Staphylococcus coagulase positivo, Salmonella spp. e Aeromonas spp. Aplicou-se aos pescadores um questionário com 20 perguntas referentes à manipulação do pescado. As amostras de gelo apresentaram qualidade microbiológica insatisfatória. O peixe serra encontrou-se contaminado por A. hydrophila, podendo veicular este agente ao ser consumido pela população.(AU)

This study aimed at evaluating the microbiological quality of the saw fish (S. brasiliensis) landed in the city of Raposa (MA) and the ice used in its conservation. Samples of ice and saw fish were subjected to analysis to determine the Most Probable Number (MPN) of coliforms, thermo-tolerants and Escherichia coli. Fish samples were also tested for Staphylococcus coagulase positive, Salmonella spp. and Aeromonas spp. Fishermen were given a questionnaire with 20 questions concerning the handling of the fish. The ice samples showed unsatisfactory microbiological quality. The saw fish was contaminated with A. hydrophila, which means it could convey this agent to be consumed by the population.(AU)

Pescada amarela (Cynoscion acoupa) desembarcada: características microbiológicas e qualidade do gelo utilizado na sua conservação / Microbiological characteristics and quality of the ice used for preserving landed yellow hake (Cynoscion acoupa)

No presente estudo foram identificadas as características microbiológicas da pescada amarela (Cynoscion acoupa) desembarcada em Cedral/MA e avaliada a qualidade do gelo utilizado na sua conservação. Foram coletadas 42 amostras de pescada e analisadas quanto à pesquisa de Salmonella spp, V. parahaemolyticus, Escherichia coli, Staphylococcus coagulase positivo, Aeromonas spp, contagem de bactérias aeróbias mesófilas e Número Mais Provável de coliformes a 35 °C e coliformes a 45 °C. Onze amostras de gelo foram analisadas quanto à contagem de coliformes a 35 °C e a 45 °C e de bactérias psicrotróficas. A pescada amarela mostrou contaminação por bactérias mesófilas, coliformes e A. hydrophila, e ausência de Salmonella, Staphylococcus coagulase positivo e V. parahaemolyticus. As amostras de gelo foram consideradas impróprias para uso na conservação do pescado.
