On the other hand, mice are only infected with trophozoites of N. fowleri; amoebas are found in the lumen of the nasal cavity covered with both IgA and IgG as well as being surrounded by many PMNs; however, all this events are not able to avoid the infection, probably because the PMNs are not being activated via the FcR as those PMNs from immunized mice (Carrasco-Yepez et al. 2014). The gene discussed is CD79A; the disease is infection.
