The Vibrio species are considered marine bacteria that exist in estuaries all over the world. Many Vibrio species cause serious human infections. We have summarized an overview of the current threat facing the world as a result of climate change which consequently affects humans and aquaculture. Little is understood regarding the possible consequences of global warming on marine prokaryotic communities due to a paucity of historical data. The biggest biological biomass in the ocean is made up of prokaryotes, which also play a vital role in the occurrence of diseases in humans and other animals as well as the cycling of nutrient elements.
