A type of microscopic algae called Karenia brevis has grown rapidly in Florida, leaving dead fish on the shore. Harmful “red tide” is wreaking smelly havoc on Florida’s Gulf Coast, canceling ...

Karenia brevis produce what are known as brevetoxins, which can kill marine life and birds. The red tide organism can also cause health problems in humans, such as skin irritation.

Florida's coastal waters are currently clear of the red tide organism, Karenia brevis, with no observable presence in samples ...

A type of toxic algae, Karenia brevis, ... K. brevis is increasing in Florida’s waters, more abundant year-round now than in the 1950s, most likely because of higher nutrients.

Florida environmental agencies are closely monitoring a minor detection of Karenia brevis, the organism responsible for red ...

T he lifecycle of Karenia brevis has only been partially described. Researchers know that haploid cells undergo mitosis (a) to boost population numbers—a process that is ramped up during red tide ...

Strength: If K. brevis becomes concentrated enough to start killing fish, it usually leads to a longer and stronger red tide event, says Robert Weisberg, an emeritus oceanography professor who ...

Published in the American Society for Microbiology's journal mSphere, the study is the first to identify viruses associated with Karenia brevis, the single-celled organism that causes red tide.By ...

Karenia brevis produces brevetoxins. For people with severe or chronic respiratory conditions, such as emphysema or asthma, the toxins can cause serious illness.

Karenia brevis is the organism that causes red tide. During red tide events, the researchers collected Karenia brevis bloom samples to analyze in a lab.
