Device to Attract and Trap Motile Aquatic Pathogens
The Caribbean region is considered a coral disease hotspot, with over 20 documented diseases and syndromes affecting over 20 species of corals. One motile marine pathogen family, Vibrionaceae, which is responsible for 50% of coral diseases, is strongly thermodependent, thus warming sea-surface temperatures, driven by pollution and global climate change,...
