The diversity of trypanosomatid RNA viruses goes far beyond the well-known leishmaniaviruses. Newly discovered viral lineages across multiple families reveal host-specific patterns and distant evolutionary transitions, highlighting the trajectories of viral acquisition and subsequent evolution shaped by parasite biology and ecology.
Parasitic plants rely on other plants for nutrients, but they steer clear of exploiting their relatives, a behavior known as kin avoidance. Recently, Xiang et al. revealed that the parasitic plant Phtheirospermum japonicum glucosylates and inactivates its haustorium-inducing factors (HIFs), thereby inhibiting prehaustorium formation and avoiding parasitism of its own species.
Loiasis remains one of the least prioritised filarial infections, yet its neglect undermines onchocerciasis elimination and limits progress toward global NTD goals. Recognising Loa loa as a neglected tropical disease would unlock resources, promote safe mass drug administration, and accelerate the World Health Organization's 2030 targets.
Vector-borne infectious diseases remain a burden within the intertropical belt, and developing holistic vector-control strategies poses a significant challenge. Recently, Tang and colleagues engineered an entomopathogenic fungus that attracts and kills mosquitoes by emitting a woody-scented compound.
Francesco Redi invented scientifically controlled experimentation. He is best known for demonstrating that insects arise only from the eggs of other insects and not spontaneously from decaying matter, and is regarded by many as the father of parasitology. Here, we highlight the foundational work of Redi for his 400th birthday.
