| aedes aegypti resistance to temephos during 2001 in several municipalities in the states of rio de janeiro, sergipe, and alagoas, brazil. | for more than 30 years temephos, an organophosphate insecticide, has been the sole larvicide used in brazil in the control of aedes aegypti. organophosphates were also used for adult control, being replaced by pyrethroids since 1999. in this same year the brazilian health foundation started the coordination of the ae. aegypti insecticide resistance monitoring program. in the context of this program, our group was responsible for the detection of temephos resistance in a total of 12 municipalitie ... | 2004 | 15250476 |
| epidemiological aspects of dengue in aracaju, state of sergipe, brazil. | the dengue fever remains to be a disease of serious public health concern, and its incidence has increased in the past decades. this study aimed to characterize the epidemiological incidence of dengue in the period 2001-2010. | 2011 | 22231240 |
| genetic variability and spatial distribution in small geographic scale of aedes aegypti (diptera: culicidae) under different climatic conditions in northeastern brazil. | the study of the genetic structure of aedes aegypti is essential to understanding their population dynamics as well as for the analysis of factors responsible for their resistance and ecological adaptation. the use of molecular markers in identifying differences amongst populations of ae. aegypti in different geographical areas as well as the temporal variation of the vector populations has contributed to the improvement of vector control strategies. the present study aims to determine the genet ... | 2016 | 27716392 |
| underreporting of dengue-4 in brazil due to low sensitivity of the ns1 ag test in routine control programs. | we have identified fifty-eight samples that were positive for dengue-4 among 119 samples with negative diagnoses for dengue via the platelia™ dengue ns1 ag in aracaju, state of sergipe, brazil. we determined that the low sensitivity of the ns1 ag test could be related to secondary dengue infections in the studied population. therefore, we concluded that the sensitivity and specificity of the platelia™ dengue ns1 ag test as a screening method for monitoring circulating dengue serotypes must be re ... | 2013 | 23717529 |
| [identification and spatial distribution of key premises for aedes aegypti in the porto dantas neighborhood, aracaju, sergipe state, brazil, 2007-2008]. | currently the best way to avoid new dengue epidemics is to control the mosquito vector aedes aegypti. this study thus aimed to identify and analyze the spatial distribution of "key premises" for ae. aegypti in aracaju, sergipe state, brazil. three entomological surveys were performed prior to, during, and after the dengue epidemic and in different conditions of precipitation: the end of the rainy season, beginning of the rainy season, and the dry season. key premises were identified by positivit ... | 2013 | 23459822 |
