Freeze-fracturing was used to study the ultrastructure of the sporozoites of P. vivax within the salivary gland (SG) of A. stephensi. The architecture of the pellicular complex of the SG sporozoites was essentially the same as that reported for the intraoocystic forms, but the outline of cross-fractured P. vivax sporozoites was more flattened and crescent shaped as opposed to the circular outline described for the intraoocystic sporozoites. The SG sporozoites of P. vivax also exhibited apical rosettes and a cytosome connected to a food vacuole, 2 unique structures not previously reported for malarial sporozoites.
