Microbial disease and the coral holobiont

Area of Science:

• Marine Biology
• Microbial Ecology
• Conservation Science

Background:

• Tropical coral reefs are vital biodiversity hotspots facing unprecedented threats from climate change and human activities.
• Emerging coral diseases disrupt the coral holobiont, a complex symbiosis essential for reef health, leading to widespread reef deterioration.
• Understanding the role of microorganisms in coral health and disease is critical for reef conservation.

Purpose of the Study:

• To review current knowledge on the role of microorganisms in coral health and disease.
• To identify interdisciplinary research priorities for elucidating coral disease mechanisms.
• To advocate for integrated approaches combining medical, veterinary, and ecological expertise for coral disease research.

Main Methods:

• Review of existing scientific literature on coral diseases and microbial roles.
• Emphasis on multidisciplinary studies integrating host-agent-environment interactions.
• Application of advanced molecular technologies (DNA, RNA, protein analysis) alongside traditional methods (histology, microbial ecology).

Main Results:

• Coral diseases significantly impact reef health by compromising the coral holobiont.
• A comprehensive understanding of disease mechanisms requires integrating diverse scientific disciplines.
• Advanced diagnostic and ecological methods are essential for accurate assessment.

Conclusions:

• Interdisciplinary research, drawing parallels with human and veterinary medicine, is paramount for advancing coral disease understanding.
• Standardized methodologies and cutting-edge technologies are needed to investigate coral mortality causes.
• This research will inform effective management strategies for mitigating coral reef decline.
