Figure 1From: Identification of novel aspartic proteases from Strongyloides ratti and characterisation of their evolutionary relationships, stage-specific expression and molecular structureLife-cycle of S. ratti. Eggs produced by mitotic parthenogenesis by parasitic females can develop either directly into iL3s by homogonic development or into free-living males and females, which reproduce sexually to produce eggs that develop into iL3s.Back to article page
