A comparison of Anopheles gambiae and Plasmodium falciparum genetic structure over space and time

Population genetic structure and subdivision are key factors affecting the evolution of organisms. In this study, we analysed and compared the population genetic structure of the malaria parasite Plasmodium falciparum and its mosquito vector Anopheles gambiae over space and time in the Nianza Province, near Victoria Lake in Kenya. The parasites wer...

Analysis of genetic variability in Anopheles arabiensis and Anopheles gambiae using microsatellite loci

We analysed genetic variability in Anopheles arabiensis and Anopheles gambiae populations using microsatellite loci to determine whether the Rift Valley restricts the flow of genes. Deviations from Hardy-Weinberg expectations were significant, and were most likely to be due to the high frequency of null alleles observed. An. arabiensis populations ...

Changes in vector species composition and current vector biology and behaviour will favour malaria elimination in Santa Isabel Province, Solomon Islands

BACKGROUND:In 2009, Santa Isabel Province in the Solomon Islands embarked on a malaria elimination programme. However, very little is known in the Province about the anopheline fauna, which species are vectors, their bionomics and how they may respond to intensified intervention measures. The purpose of this study was to provide baseline data on th...

DNA profiling of human blood in anophelines from lowland and highland sites in western Kenya

We used polymerase chain reaction (PCR)-based DNA profiling to determine the person from whom Anopheles funestus and An. gambiae collected in natural human habitations obtained their blood meals. Less than 20% of human hosts contributed to > 50% of all blood meals, and 42% were not bitten at all, including people in the age group bitten most often....

Evidence for transmission of Plasmodium vivax among a duffy antigen negative population in Western Kenya

We present evidence that a parasite with characteristics of Plasmodium vivax is being transmitted among Duffy blood group-negative inhabitants of Kenya. Thirty-two of 4,901 Anopheles gambiae and An. funestus (0.65%) collected in Nyanza Province were ELISA positive for the P. vivax circumsporozoite protein VK 247. All positives were found late in th...

Field efficacy of thermally expelled or live potted repellent plants against African malaria vectors in western Kenya

Trop Med Int Health 8(11), 1005-1011. (Nov 2003)

OBJECTIVE To estimate the effectiveness of live potted plants and thermal expulsion of plant materials in repelling African malaria vectors in traditional houses in western Kenya. METHODS Ocimum americanum, Lantana camara and Lippia ukambensis were tested in live, intact potted form whereas leaves of Corymbia citriodora, leaves and seeds of O. kili...

Field testing an enzyme-linked synthetic oligonucleotide probe for identification of Anopheles gambiae s.s. and An. arabiensis

Tests were carried out in Kenya to determine whether the enzyme-linked synthetic oligonucleotide probe (pAna 1) developed for identifying species of the Anopheles gambiae complex could be used under field conditions. The An. arabiensis male-specific pAna 1 probe was able to identify all male larval instars and adult males. However, the non-radioact...
