SporozoiteNormal numbers of oocysts produced. Normal numbers of midgut sporozoites inside oocysts. Reduced numbers of hemolymph sporozoites and no salivary gland sporozoites. Reduced egress of sporozoites from oocysts. Sporozoites are immotile inside and outside oocysts.
Liver stageNo infection of hepatocytes in vitro or mice by sporozoites isolated from midguts.
Additional remarks phenotype

Mutant/mutation
The mutant lacks expression of plasmepsin VIII

Protein (function)
P. berghei has 7 plasmepsins (aspartic proteases (PM IV-PM X).

Phenotype
Normal numbers of oocysts produced. Normal numbers of midgut sporozoites inside oocysts. Reduced numbers of hemolymph sporozoites and no salivary gland sporozoites. Reduced egress of sporozoites from oocysts. Sporozoites are immotile inside and outside oocysts. No infection of hepatocytes in vitro or mice by sporozoites isolated from midguts.
