Morphologic study of the effect of iron on pseudocyst formation in Trichomonas vaginalis and its interaction with human epithelial cells.

Background: Trichomonas vaginalis is the aetiological agent of human trichomoniasis, which is one of the most prevalent sexually transmitted diseases in humans. Iron is an important element for the survival of this parasite and the colonisation of the host urogenital tract.

Objectives: In this study, we investigated the effects of iron on parasite proliferation in the dynamics of pseudocyst formation and morphologically characterised iron depletion-induced pseudocysts.

Proteomics reveals major components of oogenesis in the reproductive tract of sugar-fed Anopheles aquasalis.

Anopheles (Nyssorhynchus) aquasalis is a malaria vector mainly distributed along the coastal regions of South and Central America. In the absence of an effective vaccine against malaria, strategies for controlling the vector are the main tool for interrupting parasite transmission. Mechanisms of oogenesis and embryogenesis in anautogenous mosquitoes are mainly modulated by blood feeding.
