The incidence of V. vulnificus infections is increasing, especially in northern parts of the United States, compared to 20 years
Korvikt [17]

Answer:

The effects of climate change may be associated with the increased incidence of <em>V. vulnificus</em> infection

Explanation:

<em>Vibrio vulnificus</em> is a harmful bacterium that causes a serious disease due to eating contaminated seafood, which is the main cause of seafood-related deaths in the USA. <em>V. vulnificus</em> is naturally present in the flora of coastal waters around the world and this bacterium has been isolated from a variety of seafood (e.g.., fish, oysters, shrimp, etc). Epidemiologic studies have shown that the incidence of <em>V. vulnificus</em> infection has increased dramatically since 1996. During this same period, climate change has been responsible for the increase in salinity and temperature of the coastal waters (i.e., the natural habitat of this bacterium). In consequence, it is reasonable to suppose that the change in climatic conditions may be associated with the increased incidence of <em>V. vulnificus</em> infection.
