Effects of microplastics on Daphnia-associated microbiomes in situ and in vitro
This study investigated how microplastic exposure alters the microbiome associated with Daphnia in freshwater, finding shifts in bacterial community composition that may affect host health and ecological function. The results suggest that microplastics can indirectly harm zooplankton by disrupting their microbial symbionts.
Impact of Schistosoma sp., infection on biological, behavioral, physiological, histological, and genotoxicological aspects of Biomphalaria alexandrina and Bulinus truncatus snails
Not relevant to microplastics research; this paper studies how Schistosoma parasite infection alters the physiology, behavior, reproduction, and tissue health of freshwater snails that serve as intermediate hosts, with no connection to microplastic pollution.
Population response of intestinal microbiota to acute Vibrio alginolyticus infection in half-smooth tongue sole (Cynoglossus semilaevis)
Researchers examined intestinal microbiota responses to acute Vibrio alginolyticus infection in half-smooth tongue sole, finding that infection increased vulnerability to secondary infections by intestinal pathogens and promoted antibiotic resistance gene transfer.
More deterministic assembly constrains the diversity of gut microbiota in freshwater snails
Researchers compared the gut microbiota assembly processes of invasive and native freshwater snails coexisting at multiple sites in southern China. They found that invasive snails exhibited more deterministic gut microbiome assembly with lower microbial diversity, which may contribute to their competitive advantage. The study provides insights into how gut microbial community dynamics may influence the success of invasive species in freshwater ecosystems.
