A highly sensitive, nested polymerase chain reaction based method using simple DNA extraction to detect malaria sporozoites in mosquitos

Vythilingam, I, Nitiavathy, K, Yi, P, Bakotee, B, Hugo, B, Singh, B, Wirtz, RA, Palmer, K
Southeast Asian J Trop Med Public Health 30(4), 631-5. (1999-12)

Dried Anopheles farauti mosquitos caught in Solomon Islands in 1990 were examined for malaria sporozoites by ELISA and nested polymerase chain reaction (PCR). Only heads and thoraces were used. Plasmodium genus-specific nested PCR amplifications were carried out on all samples. Of the 402 pools of mosquitos that were processed, 30 were positive for...

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...

"Clonal" population structure of the malaria agent Plasmodium falciparum in high-infection regions

The population genetic structure of Plasmodium falciparum, the agent of malignant malaria, has been shown to be predominantly "clonal" (i.e., highly inbred) in regions of low infectivity; in high-infectivity regions, it is often thought to be panmictic, or nearly so, although there is little supporting evidence for this. The matter can be settled b...

Comparative determination of Plasmodium falciparum sporozoite rates in Afrotropical Anopheles from Kenya by dissection and ELISA

Adungo, N. I., Mahadevan, S., Mulaya, N. L., Situbi, A. P., Githure, J. I.
Ann Trop Med Parasitol 85(4), 387-94. (1991)

The Plasmodium falciparum rate was determined by microscopical examination of one salivary gland (three lobes) and by enzyme-linked immunosorbent assay (ELISA) of the other salivary gland in each of 1580 Anopheles mosquitoes collected from western Kenya during both the wet and dry seasons. The sporozoite rate in the wet season was much higher than ...

Detection of human antibodies against Plasmodium falciparum antigens in blood meals of anopheline mosquitoes

Contreras, C. E., Beier, J. C.
J Am Mosq Control Assoc 8(3), 252-5. (Sep 1992)

Human IgG antibodies against Plasmodium falciparum asexual stages, gametocytes and sporozoites were detected by indirect fluorescent antibody (IFA) techniques in the blood meals of Anopheles gambiae s.l. from a malaria-endemic area of western Kenya. Field-collected mosquitoes, which had been stored dry for over 2 years, were screened first for huma...

Effect of permethrin-treated bed nets on the spatial distribution of malaria vectors in western Kenya

Gimnig, J. E., Kolczak, M. S., Hightower, A. W., Vulule, J. M., Schoute, E., Kamau, L., Phillips-Howard, P. A., ter Kuile, F. O., Nahlen, B. L., Hawley, W. A.
Am J Trop Med Hyg 68(4 Suppl), 115-20. (2003)

The effect of insecticide (permethrin)-treated bed nets (ITNs) on the spatial distribution of malaria vectors in neighboring villages lacking ITNs was studied during a randomized controlled trial of ITNs in western Kenya. There was a trend of decreased abundance of Anopheles gambiae with decreasing distance from intervention villages both before (P...

Effect of Plasmodium falciparum on blood feeding behavior of naturally infected Anopheles mosquitoes in western Kenya

Wekesa, J. W., Copeland, R. S., Mwangi, R. W.
Am J Trop Med Hyg 47(4), 484-8. (1992)

Feeding behavior was compared between infected and uninfected field-collected groups of Anopheles gambiae sensu lato and An. funestus from western Kenya. A significantly greater percentage (81%) of Plasmodium falciparum-infected An. gambiae s.l. females probed on experimental hosts (hamsters) than did uninfected females (38%). Among those females t...

Evaluation of fenitrothion for the control of malaria

Fontaine, RE, Pull, JH, Payne, D, Pradhan, GD, Joshi, GP, Pearson, JA, Thymakis, MK, Camacho, ME
Bulletin of the World Health Organization 56(3), 445-52. (1978)

Fenitrothion was evaluated for residual spraying in antimalaria programmes in a large-scale field trial near Kisumu, Kenya from 1972 to 1976. The insecticide was applied in a hyper/holoendemic malarious area of 200 km(2) inhabited by about 50 000 people. All houses and animal shelters were sprayed at a target dosage rate of 2 g/m(2) at 3-month inte...
