DNA reveals chemosynthesis genes in bacteria living on coral reef fish gills‎

Chemosynthetic bacteria have been documented in various marine environments and in association with invertebrate hosts such as annelid worms and mollusks, but their presence in fish appears to be a new discovery. The findings show that fish gills host a complex and specialized microbiome that is not yet well understood but could play an important role in fish metabolism, immunity and health.
