Beyond a single bacterial fix: systemic climate, pollution, and community actions needed to safeguard Caribbean reefs

Laboratory assays show that the predatory bacterium V. carnivora lyses Vibrio coralliilyticus, a key pathogen of White‑Band disease, reducing infection rates by up to 70% in controlled tanks. However, field trials reveal variable efficacy due to temperature spikes and nutrient loads, underscoring the need for multi‑factorial experimental designs. Robust longitudinal monitoring and meta‑analysis are essential before scaling up.
The predatory bacterium offers a valuable tool, but its impact is bounded by the larger climate, pollution, and governance context that drives coral disease.
Historical patterns of colonial exploitation and contemporary over‑tourism have eroded reef resilience, a reality that Indigenous stewardship and cross‑cultural practices can help reverse when integrated into policy and technology. By embedding microbial biocontrol within community‑led nurseries, robust water‑quality legislation, and open‑access benefit‑sharing frameworks, actors—from local fishers to international donors—can co‑create a resilient reef system that addresses both the microscopic and systemic threats. This holistic approach aligns scientific rigor with cultural wisdom, ensuring that the cure does not become a new source of inequity.
