Why is there an optimal pH for malaria evaluation?
Trophozoites of P.vivax stained at pH7.4 (A) or pH6.9 (B ad C). Note that staining at the more alkaline conditions (pH7.4) gives the red cell a pale blue colour when compared to the acidic conditions (pH6.9), with these conditions making both the trophozoite and the added cytoplasmic dots more visible. Where pH7.4 is used the key features of parasite shape and red cell morphology can still be seen, but parasites are less evident and dots may be fainter (B) or absent (C). Description
