DOI: 10.1002/jmor.21292
Abstract: The process of spermatogenesis and spermatozoon morphology was characterized from a deep‐sea bivalve, Calyptogena pacifica (Vesicomyidae, Pliocardiinae), a member of the superfamily Glossoidea, using light and electron microscopy. Spermatogenesis in C. pacifica is generally similar… read more here.

DOI: 10.1002/jmor.21524
Abstract: In contrast to numerous studies on spermatozoa length, relatively little work focuses on the width of spermatozoa, and particularly the width of the midpiece and flagellum. In flagellated spermatozoa, the flagellum provides forward thrust while… read more here.

DOI: 10.1016/j.cub.2019.08.034
Abstract: Bees can protect themselves from infection by accumulating specific nectars in the honey crop. A new study shows that as parasites pass through the crop, their flagellum is thereby removed, which prevents host infection. read more here.

DOI: 10.1016/j.micpath.2020.104057
Abstract: Some serovars of salmonella cause huge global diseases such as enteric fever and invasive non typhoidal Salmonella disease. Flagellin as a key antigenic component of salmonella, can induce humoral and cellular immunity responses. In this… read more here.

DOI: 10.1126/scisignal.abc6435
Abstract: Flagellum inheritance in trypanosomes requires strategically timed suppression of Polo-like kinase activity. Passing the flagellum in trypanosomes The single flagellum of the unicellular parasite Trypanosoma brucei is critical for virulence, and Polo-like kinase (TbPLK) is… read more here.

DOI: 10.1128/mbio.00736-17
Abstract: ABSTRACT Flagellum-driven motility of Salmonella enterica serovar Typhimurium facilitates host colonization. However, the large extracellular flagellum is also a prime target for the immune system. As consequence, expression of flagella is bistable within a population… read more here.
