Morphology of the daughter sporocysts of Cercaria etgesii Shchenkov, 2017 (Pleurogenidae) has been described according to conventional histological techniques and subsequent 3D reconstruction with Bitplanelmaris® software. Novel data were obtained concerning the spatial organization of the brood cavity of Pleurogenidae daughter sporocysts. It was shown that the laminated structures of the endocyst are lining the brood cavity and carry out its compartmentalisation by formation of the chambers around developing and disintegrating embryos of cercariae. First description of the germinal mass of the Pleurogenidae daughter sporocysts is given. No mitoses in germinal mass were evident although apparent production of the cercariae embryos by the sporocysts take place. The analogous principle of daughter sporocysts morphofunctional organisation was noted for the studied representatives of closely related taxa of trematodes: Pleurogenidae (C. etgesii) and Microphallidae (Microphallus 'pygmaeus' group).

A single-cell atlas of the miracidium larva of reveals cell types, developmental pathways, and tissue architecture.

Wellcome Sanger Institute, Wellcome Genome Campus, Hinxton, United Kingdom.
Article Synopsis
- The text discusses a parasitic flatworm's life cycle, focusing on the miracidium stage which infects freshwater snails to eventually cause schistosomiasis in humans.
- Researchers created a detailed cellular atlas revealing the 365 cells in the miracidium and identified 19 distinct cell clusters through single-cell RNA sequencing.
- The study found that most of the larva's cells are somatic, with a small percentage being stem cells, and the stem cells display distinct characteristics potentially related to sex.

Article Synopsis
- * Researchers created a gene knockout strain (RHΔ) to study the role of the HAD2a gene, finding that it is crucial for the parasite's replication and virulence.
- * Vaccination with the RHΔ strain showed promising results in mice, providing partial to strong protection against various strains of the disease, indicating its potential as a candidate for developing more effective vaccines.

Introduction: Apicomplexan AP2 family of proteins (ApiAP2) are transcription factors (TFs) that regulate parasite growth and development, but little is known about the ApiAP2 TFs in spp. sequence is predicted to encode a ApiAP2 protein (EnApiAP2).
Methods: The cDNAs encoding full-length and truncated EnApiAP2 protein were cloned and sequenced, respectively.

Plasmodium parasites have a complex life cycle alternating between a mosquito and a vertebrate host. Following the bite of an Anopheles female mosquito, Plasmodium sporozoites are transmitted from the skin to the liver; their first place of replication within the host. Successfully invaded sporozoites undergo a massive replication and growth involving asynchronous DNA replication and division that results in the generation of tens of thousands or even hundreds of thousands of merozoites depending on the Plasmodium species.

Article Synopsis
- The study tracked the location of S. mansoni larvae within Biomphalaria glabrata snails after infection, noting they initially reside in the head-foot area before moving to the hepatopancreas and ovotestis at later stages.
- Using extracts from different snail organs for lab culturing revealed that the head-foot extract supports extended larval growth, while combined use with the hepatopancreas extract enhances the larvae's development into sporocysts.
