What is aspergillosis?
aspergillosis meaning a widespread fungal infection of Caribbean soft corals. It affects six species of sea fans and sea whips. The pathogen is Aspergillosis sydowii, a terrestrial fungus which infects gorgonia after germination of spores on the coral surface. This is followed by penetration and spread of hyphae in coral tissue, resulting in highly visible lesions which may be associated with complete loss of tissue and skeleton. Lesions often occur at multiple sites across an infected colony.-Purple galls may be produced by the coral host to encapsulate fungal hyphae.
