Venn diagrams indicating the amount of secreted salivary proteins identified in four Anopheles species. The amount of putative secreted proteins identified by MS in An. gambiae, An. arabiensis, An. stephensi and An. albimanus SGEs was represented at each taxonomic level (q.v., Figure 1A, 1B). The percentage of proteins identified is indicated in bold with the corresponding number of protein in brackets.
