Comparative analysis of differentially expressed haemocyte genes with those seen in our previous experiments performed following in vivo infection of B. glabrata with S. mansoni revealed: two unknown genes (DY523254/DY523255) previously identified in haemocytes 2–24 h post-infection by SSH [10]; 12 genes including elongation factor 2, ubiquitin-conjugating enzyme E2D 2, elastase 2-like, exported avidin family protein, one hypothetical protein; and a further seven unknowns found previously in haemocytes 2–24 h post-infection using the 2K microarray [24]. Here, EEF2 is linked to infection.
