Gulf Coast Urged to Watch for Deadly Vibrio Bacteria in Warm Waters

Health officials warn that Vibrio vulnificus, a bacteria thriving in warm, brackish Gulf waters, can cause severe illness from contaminated shellfish (often raw oysters) or exposed wounds and can progress rapidly to bloodstream infection, especially in people with liver disease or weakened immunity. Florida has 14 cases and 2 deaths, Louisiana 9 cases and 5 deaths so far this year. Warning signs include worsening pain, redness, swelling, fever, discharge or blistering; seek medical care urgently. Treatment typically involves antibiotics, sometimes IV antibiotics and sepsis care. Prevention includes thorough shellfish cooking and avoiding seawater exposure with wounds. The CDC advises prompt treatment if Vibrio infection is suspected; warmer water, flooding, and major weather events can raise Vibrio levels along the Gulf.

FDA warns WA-sourced oysters and clams may carry norovirus across nine states

The FDA warned that certain raw oysters from Drayton Harbor Oyster Co. and Manila clams from Lummi Indian Business Council harvested Feb. 13–Mar. 3 may be contaminated with norovirus and distributed to retailers and restaurants in Arizona, California, Florida, Georgia, Illinois, Nevada, New York, Oregon and Washington. Restaurants and retailers should not sell or serve these shellfish and should dispose of them or arrange destruction to prevent cross-contamination. Illness typically begins 13–48 hours after exposure and lasts 24–72 hours.

"Shellfish Face Ancient Cancer Epidemic: A Virus-Like Spread Unveiled"

Scientists have discovered two strains of an ancient form of leukemia-like cancer that spreads among shellfish, similar to how Tasmanian devils and dogs transmit cancer cells. The transmissible tumor cells float in the water and are taken up by clams, multiplying and replicating in their hosts before escaping to attack others. This discovery raises the possibility that there may be more forms of transmissible cancer in the animal kingdom, posing a potential threat to humans. The research also revealed that the cancer cells in shellfish exhibit highly variable amounts of genetic material, challenging the belief that cancers require stable genomes to survive long-term.

Centuries-Long Spread of Bizarre Cancer Among Shellfish Unveiled

Scientists have discovered that a bizarre form of contagious cancer has been spreading among shellfish for centuries, possibly even thousands of years. The cancer cells, which originated from a single ancestral cell, invade and multiply inside their new victims before spreading to attack other shellfish. This phenomenon has been observed in various species of shellfish, including clams and cockles. Researchers have found that these contagious cancers have accumulated a surprising number of mutations over time, with some cells having extra chromosomes or duplicated genomes. The ability of these cancers to survive and mutate for such long periods remains a mystery, but studying them could provide insights into cancer in humans and potentially uncover new targets for drugs.

Species Adaptation During Earth's Largest Extinction: A Study on Shell Life Competition

A new study conducted by paleontologists from the University of Bristol and Wuhan University challenges the long-held belief that bivalves outcompeted brachiopods during the end-Permian mass extinction. The research, published in Nature Communications, suggests that both groups were equally affected by the crisis and responded to similar external drivers. While bivalves eventually thrived and adapted to high ocean temperatures, brachiopods retreated to deeper waters. The study sheds light on the evolution of life after the mass extinction and the construction of modern ecosystems.
