Experimental malaria infections in 'saltwater' and 'freshwater' Anopheles gambiae from East Africa

1. 1) Two insectary strains of Anopheles gambiae, a typical “freshwater” strain and a “saltwater” variant, from East Africa, were found to be susceptible to infection with local strains of Plasmodium falciparum. 2. 2) The data indicated that the “freshwater,” or “Kisumu,” strain was slightly more susceptible to infection than the “saltwater” strain when fed on subjects with moderate to high gametocyte densities.
