Name of the mutant parasite
RMgm numberRMgm-312
Principal name1318cl3
Alternative nameH-ko
Standardized name
Is the mutant parasite cloned after genetic modificationYes
top of page
Phenotype
Asexual blood stageNot different from wild type
Gametocyte/GameteNot different from wild type
Fertilization and ookineteNot different from wild type
OocystNormal numbers of oocysts are produced. In mature oocysts sporozoites are formed comparable to wild type. However, sporozoites do not egress from the oocysts (and only very low numbers of hemocoel sporozoites are detected)
SporozoiteSporozoites do not egress from the oocysts. Only very low numbers of hemocoel sporozoites are detected. Analysis of dissected salivary glands showed very low numbers of sporozoites (3800 sporozoites) compared to wild type (126.500 sporozoites). No further analysis was performed to determine whether these sporozoites are inside the salivary glands or were attached to the outside of the glands.
Liver stageNo blood stage infection after infection of mice by bite of infected mosquitoes
Additional remarks phenotype

Mutant/mutation
The parasite lacks expression of PBANKA_143370

Protein (function)
No information (see 'Additional information').

Phenotype
The phenotype has not been analyzed in detail. Blood stage development and gametocyte, ookinete and oocyst production were comparable to those of wild type.The phenotype analyses indicate a defect in the formation and/or egress of sporozoites from oocysts.

Additional information
The gene (gene H) was selected in a screen for genes with abundant transcripts in salivary gland sporozoites and the absence of the protein product as reported in proteome analyses of sporozoites.

The phenotype has not been published. The mutant can be obtained from the Leiden Malaria Research Group.
