To assess the relative contribution of both macrophages and neutrophils to control Salmonella infection, Tg(mfap4:mCherry-F/mpx:GFP) embryos were infected in the HBV with E2Crimson fluorescent Salmonella (Sal-E2Crimson) and imaged from 3 to 14 hpi (Figure 3G and Video 4). The gene discussed is MFAP4; the disease is Salmonella Infections.
