Vector-related case-control study of severe malaria in Kilifi District, Kenya.

A case-control study examined vector-related and environmental parameters associated with severe malaria in Kilifi District along the coast of Kenya. Over an 11-month period, 119 children identified with severe malaria infections at the Kilifi District Hospital were matched by age with control children who reported to the outpatient clinic with nonsevere infections. Intensive mosquito sampling was done in each of the case-control houses over a four-day period, beginning within a week of index case admission.

Relationships between Plasmodium falciparum transmission by vector populations and the incidence of severe disease at nine sites on the Kenyan coast.

The transmission of Plasmodium falciparum was studied in relation to the incidence of severe malaria infections at nine sites in the Kilifi District in Kenya. Intensive mosquito sampling during a one-year period yielded Anopheles gambiae s. l.

Differentiation of vector species of phlebotominae (Diptera: Psychodidae) in Kenya by chorionic sculpturing of their eggs.

Chorionic sculpturing on eggs of Phlebotomus pedifer Lewis, Mutinga, and Ashford; the closely related Phlebotomus aculeatus Lewis, Minter, and Ashford (= P. elegonensis Ngoka, Madel, and Mutinga); and Phlebotomus martini Parrot was examined and compared by scanning electron microscopy. The eggs of P.

Characterization of Simulium (Edwardsellum) damnosum s.l. populations from six river systems in Kenya by cellulose acetate electrophoresis.

Isoenzyme characterization of the Simulium damnosum Theobald sibling species complex from two widely separated geographical areas in Kenya is presented based on 10 enzymatic loci. Four river systems in Western and Nyanza Provinces, namely, the Yala, Lusumu, Isiukhu and the Nzoia harbouring S. damnosum s.
