NewsScientists warn of rise in flesh-eating bacterial infection due to global warming
Continued warming of the climate would see a rise in the number and spread of potentially fatal infections caused by bacteria found along parts of the coast of the United States, researchers predict. Vibrio vulnificus bacteria grow in warm shallow coastal waters and can infect a cut or insect bite ...
