Galactic tides

Like the earth’s oceans at their shores, the universe’s galaxies also experience tides, but on a much larger scale called as Galactic tides.
About:

Vibrio vulnificus

Vibrio vulnificus is a bacterium found near oceans which can become a threat to coastal communities.
About the species:
- V vulnificus belongs to the same family as Vibrio cholerae, which causes cholera, a highly contagious diarrhoeal disease.
- Vibrio vulnificus is a bacterium that causes septicemia, severe wound infections, and gastroenteritis.
- Failure to recognize and treat this infection promptly leads to high morbidity and mortality.
- Most Vibrio infections are caused by eating raw or undercooked oysters or other shellfish.
Threats:
- In India, the sea surface temperatures average 28°C, making the waters conducive to growth and proliferation of V vulnificus.
- Despite conducive marine conditions and a long coastline, reports of human infections of V vulnificus from India are sparse.
- Researchers have also routinely found V vulnificus in seafood and marine environments in India.
- The microbes can enter the digestive tract when people eat raw or undercooked seafood. “As Indians mostly consume properly cooked seafood, they are less at risk of contracting the infection through this route.
