Table 1 Promastigotes from gut smears were measured under light microscopy with an oil-immersion objective. MIG (Lutzomyia migonei). BRA (Leishmania (Viannia) braziliensis). LONG (Lutzomyia longipalpis). INF (Leishmania (Leishmania) infantum). PI (postinfection). EN (elongated nectomonads). SN (short nectomonads). HAP (haptomonads). MET (metacyclic promastigotes).

From: Experimental infections and co-infections with Leishmania braziliensis and Leishmania infantum in two sand fly species, Lutzomyia migonei and Lutzomyia longipalpis
