) and genotypes were detected by a Knockdown resistance kdr CYP9K1 MOLDI-TOF based SNP genotyping assay (Sequenom iPLEX) in samples of collected at 13 sites throughout the Union of the Comoros Anopheles gambiae and Dar es Salaam, Tanzania during February and March 2011. All . A gambiae specimens collected in the Comoros were homozygous for the susceptible kdr alleles (+/+) while 96% of from Dar es Salaam were homozygous A. gambiae for the East African resistant genotype (E/E). In contrast, all specimens from kdr Dar es Salaam and the Comoros were homozygous for the cyp3 allele (c3/c3) at the CYP9K1 locus; the locus has been implicated in metabolic resistance against pyrethroid insecticides in West Africa. All specimens had typical A. genotypes for SNPs within the on all three gambiae divergence Islands chromosomes. Although further spatial and temporal studies are needed, the distribution of genotypes between the Comoros and Tanzania further kdr supports isolation of the Comoros populations from populations on A. gambiae mainland Africa. 1 2 1 1 2 3 1

Absence of kdr resistance alleles in the Union of the Comoros, East Africa
Knockdown resistance ( kdr) and CYP9K1 genotypes were detected by a MOLDI-TOF based SNP genotyping assay (Sequenom iPLEX) in samples of Anopheles gambiae collected at 13 sites throughout the Union of the Comoros and Dar es Salaam, Tanzania during February and March 2011. All A. gambiae specimens collected in the Comoros were homozygous for the susceptible kdr alleles (+/+) while 96% of A. gambi...
متن کاملA new high-performance PCR diagnostic for the detection of pyrethroid knockdown resistance kdr in Anopheles gambiae.
Monitoring the spread of the knockdown resistance allele kdr in areas of extensive pyrethroid use is critical to vector-control projects. Currently available methods for detecting kdr from DNA samples are characterized by poor amplification, time-consuming steps, and primers that exhibit frequent null alleles. We describe a new PCR diagnostic that uses fluorescent primers based on conserved pri...
متن کاملAn unusual distribution of the kdr gene among populations of Anopheles gambiae on the island of Bioko, Equatorial Guinea.
In West Africa, Anopheles gambiae exists in discrete subpopulations known as the M and S molecular forms. Although these forms occur in sympatry, pyrethroid knock-down resistance (kdr) is strongly associated with the S molecular form. On the island of Bioko, Equatorial Guinea we found high frequencies of the kdr mutation in M form individuals (55.8%) and a complete absence of kdr in the S form....
متن کاملPhylogeographic Reconstructions of a Rift Valley Fever Virus Strain Reveals Transboundary Animal Movements from Eastern Continental Africa to the Union of the Comoros.
Major explosive outbreaks of Rift Valley fever (RVF), an arthropod borne zoonotic disease, occur in humans and animals with significant mortality and economic impact across continental Africa and the Indian Ocean region (Madagascar, the Comoros archipelago). Recently, sporadic human cases have been reported in Mayotte and Grande Comore, two islands belonging to the Comoros archipelago. To ident...
متن کاملMultiple Origins of Knockdown Resistance Mutations in the Afrotropical Mosquito Vector Anopheles gambiae
How often insecticide resistance mutations arise in natural insect populations is a fundamental question for understanding the evolution of resistance and also for modeling its spread. Moreover, the development of resistance is regarded as a favored model to study the molecular evolution of adaptive traits. In the malaria vector Anopheles gambiae two point mutations (L1014F and L1014S) in the v...
