The protist exhibits several extracellular stages characterized by the presence of a long and motile flagellum and one intracellular life cycle stage termed amastigote, which possesses a tiny flagellum barely exiting the flagellar pocket. This stage was so far described as replicative but immotile cells. Unexpectedly, the recent work of M. M. Won, T. Krüger, M. Engstler, and B. A. Burleigh (mBio 14:e03556-22, 2023, https://doi.org/10.1128/mbio.03556-22) revealed that this short flagellum actually displays beating activity. This commentary explores how such a short flagellum could be constructed and why it could affect the parasite's survival inside the mammalian host.

Programming precise and specific microbial intraspecies or interspecies interaction would be powerful for microbial metabolic regulation, signal pathway mechanism understanding, and therapeutic application. However, it is still of great challenge to develop a simple and universal method to artificially encode the microbial interactions without interfering with the intrinsic cell metabolism. Here, we proposed an extensible and flexible framework nucleic acid strategy for encoding the specific and precise microbial interactions upon self-assembly.

In the phylum Nemertea, the class Hoplonemertea (former Enopla) comprises the largest number of studied species with complex spermatozoa. Asteronemertes gibsoni Chernyshev, 1991, a nemertean species having a symbiotic relationship with sea stars, is characterized by complex filiform spermatozoa. Here, spermatogenesis and spermatozoon structure in A.
