Title: Genotyping by array of Anopheles gambiae infected with Serratia marcescens      
dateReleased:
11-30-2013
description:
Anopheles gambiae mosquitoes of the M form N'gousso laboratory colony were antibiotic treated and subsequently orally infected with the Db11-GFP fluorescent strain of Serratia marcescens. Bacteria-fed mosquitoes were separated 2 days post infection based on the presence in the mosquito gut of a dye contained in the sugar solution. Mosquitoes were dissected 5 days post infection and the level of S. marcescens infection was determined through microscopic observation of mosquito guts under a fluorescence microscope. Highly infected mosquitoes, with an extensive presence of fluorescent S. marcescens throughout their gut and non-infected mosquitoes, with no sign of fluorescence traced in their gut, were further used for SNP genotyping. Genomic DNA from pools of 15 highly infected and 15 non-infected mosquitoes, in equimolar amounts, was hybridized in a customized Affymetrix 400k SNP genotyping arrays, interrogating genetic variation at ~400,000 variable positions in the An. gambiae genome, as determined by a previous sequencing effort of M/S An. gambiae molecular forms. Allele calls in both array hybridizations were used to determine the minor allele frequency difference for each individual SNP between the two phenotypic pools, which were subsequently used to determine loci associated with the outcome of S. marcescens infection.
