| the remarkable journey of adaptation of the plasmodium falciparum malaria parasite to new world anopheline mosquitoes. | plasmodium falciparum originated in africa, dispersed around the world as a result of human migration and had to adapt to several different indigenous anopheline mosquitoes. anophelines from the new world are evolutionary distant form african ones and this probably resulted in a more stringent selection of plasmodium as it adapted to these vectors. it is thought that plasmodium has been genetically selected by some anopheline species through unknown mechanisms. the mosquito immune system can gre ... | 0 | 25185006 |
| mutations in the voltage-gated sodium channel gene of anophelines and their association with resistance to pyrethroids - a review. | constant and extensive use of chemical insecticides has created a selection pressure and favored resistance development in many insect species worldwide. one of the most important pyrethroid resistance mechanisms is classified as target site insensitivity, due to conformational changes in the target site that impair a proper binding of the insecticide molecule. the voltage-gated sodium channel (nav) is the target of pyrethroids and ddt insecticides, used to control insects of medical, agricultur ... | 2014 | 25292318 |
| anopheles species composition explains differences in plasmodium transmission in la guajira, northern colombia. | malaria in la guajira, the most northern state of colombia, shows two different epidemiological patterns. malaria is endemic in the municipality of dibulla whereas in riohacha it is characterised by sporadic outbreaks. this study aimed to establish whether differences in transmission patterns could be attributed to different vector species. the most abundant adult female species were anopheles aquasalis, exclusive to riohacha, and anopheles darlingi, restricted to dibulla. anopheles mosquitoes w ... | 0 | 25411002 |
| hybrid sterility in crosses between two brazilian sibling species of the anopheles albitarsis complex. | complexes of cryptic species are common in several taxa and this is also the case in the anopheles genus, a group including all known human malaria vectors. the anopheles albitarsis complex comprises at least nine cryptic species, some of which are implicated as vectors of human malaria. several different types of data have been generated for this species complex such as cytogenetics, alloenzymes, morphological and feeding behavioral, hybridization experiments, rapd-pcr and rflp and mitochondria ... | 2014 | 25471342 |
| an overview of malaria transmission from the perspective of amazon anopheles vectors. | in the americas, areas with a high risk of malaria transmission are mainly located in the amazon forest, which extends across nine countries. one keystone step to understanding the plasmodium life cycle in anopheles species from the amazon region is to obtain experimentally infected mosquito vectors. several attempts to colonise anopheles species have been conducted, but with only short-lived success or no success at all. in this review, we review the literature on malaria transmission from the ... | 2015 | 25742262 |
| a nuclear ribosomal dna pseudogene in triatomines opens a new research field of fundamental and applied implications in chagas disease. | a pseudogene, designated as "ps(5.8s+its-2)", paralogous to the 5.8s gene and internal transcribed spacer (its)-2 of the nuclear ribosomal dna (rdna), has been recently found in many triatomine species distributed throughout north america, central america and northern south america. among characteristics used as criteria for pseudogene verification, secondary structures and free energy are highlighted, showing a lower fit between minimum free energy, partition function and centroid structures, a ... | 2015 | 25760450 |
