Sedimentary Vibrio Blooms in the Xisha Islands May Associate with the 2020 Coral Bleaching Event.

ABSTRACT: Coral reefs are among the most biodiverse ecosystems, providing habitats for various organisms. Studies on coral bleaching have been increasing recently, but little is known about the distribution and community assembly of coral pathogenic bacteria (e.g., several Vibrio species). We elucidated the distribution pattern and interaction relationships of total bacteria and Vibrio spp. in sediments from the Xisha Islands, which are characterized by their high coverage and diversity of coral resources. Vibrio spp. showed significantly higher relative abundance values in the Xisha Islands (1.00 × 10⁸ copies/g) than in other areas (approximately 1 × 10⁴ to 9.04 × 10⁵ copies/g), indicating that the coral bleaching event of 2020 may have promoted
