Asymptomatic Carriers of Plasmodium spp. as Infection Source for Malaria Vector Mosquitoes in the Brazilian Amazon
Although the asymptomatic group infected mosquitoes at a much lower rate, these patients remain infective longer than treated, symptomatic patients, and have implications for the malaria control program in Brazil, which focuses essentially on the treatment of symptomatic Patients. Expand
Amazonian malaria vector anopheline relationships interpreted from ITS2 rDNA sequences
Rdosomal DNA sequences of the second internal transcribed spacer (ITS2) from samples of 16 species of Anopheles captured in the Amazon Basin, Brazil proved to be a useful tool for species identification and, potentially, to solve taxonomic problems. Expand
Mosquito transgenesis: what is the fitness cost?
The generation of transgenic mosquitoes with a minimal fitness load is a prerequisite for the success of strategies for controlling mosquito-borne diseases using transgenic insects, and realistic estimates of transgene fitness costs are essential for modeling and planning release strategies. Expand
The second internal transcribed spacer of nuclear ribosomal DNA as a tool for Latin American anopheline taxonomy - a critical review.
Overall the ITS2 sequences distinguish anopheline species, however, information on intraspecific and geographic variations is scarce and it is suggested that misidentification and/or sequencing errors could be responsible for some of the high values of divergence. Expand
Sequence analysis of the second internal transcribed spacer of ribosomal DNA in Anopheles oswaldoi (Diptera: Culicidae).
Analysis of sequence divergence in the second internal transcribed spacer of ribosomal DNA provided evidence that An. Expand
Kerteszia subgenus of Anopheles associated with the Brazilian Atlantic rainforest:current knowledge and future challenges
The current state of knowledge about Kerteszia species in relation to the Atlantic rainforest ecosystem was discussed, and emphasis was placed on ecological characteristics related to epidemiological aspects of this group of mosquitoes. Expand
Genetic control of mosquitoes: population suppression strategies.
Releasing of Insects carrying a dominant lethal gene (RIDL) offers a solution to many of the drawbacks of traditional SIT that have limited its application in mosquitoes while maintaining its environmentally friendly and species-specific utility. Expand
Transgenic malaria-resistant mosquitoes have a fitness advantage when feeding on Plasmodium-infected blood
It is shown that when feeding on Plasmodium-infected blood, transgenic malaria-resistant mosquitoes have a selective advantage over nontransgenic mosquitoes, which has important implications for devising malaria control strategies by means of genetic modification of mosquitoes. Expand
Anopheles oswaldoi a potential malaria vector in Acre, Brazil.
Analysis of ITS2 DNA sequences from Brazilian Anopheles darlingi (Diptera: Culicidae).
Specimens of Anopheles darlingi Root, the major vector of malaria in Brazil, were collected from several states and a 4-5% sequence divergence was observed in the ITS2 of mosquitoes captured in the southeast (Dourado); further analysis is needed to determine if these differences indicate that Dourado population may be a separate species.
