Vibrio vulnificus

Facts for Prelims (FFP)


Source: DTE

 Context: Vibrio vulnificus, a marine bacterium, could pose a major threat to coastal populations due to ideal conditions created by climate change.

  • This bacterium can cause life-threatening infections and has a high mortality rate, particularly among those with weakened immune systems or comorbidities.



  • Underreported Cases: Researchers suggest that cases of Vibrio vulnificus infections are likely underreported in India.
  • Climate Change Impact: As climate change leads to more frequent cyclones, heavy rainfall, and flooding, coastal communities may face an increased risk of exposure to Vibrio vulnificus.
  • India’s sea surface temperatures are conducive to the growth of Vibrio vulnificus.
  • Mortality Rate: Vibrio vulnificus has a high mortality rate, particularly when it enters the bloodstream.
  • Preventive Measures: Researchers are developing tools to predict the abundance of Vibrio vulnificus based on sea surface temperature and phytoplankton levels
