Researchers say the intricate relationship between the algae, called sargassum, plastic marine debris and vibrio bacteria create the perfect “pathogen” storm. Here's what they're finding.
Little is known about the ecological relationship of vibrios and sargassum, according to FAU, which says that open ocean vibrios represent a group of microbes that went undescribed until now.
“Another interesting thing we discovered is a set of genes called ‘zot’ genes, which causes leaky gut syndrome,” said Mincer. “For instance, if a fish eats a piece of plastic and gets infected by this vibrio, which then results in a leaky gut and diarrhea, it’s going to release waste nutrients such nitrogen and phosphate that could stimulate Sargassum growth and other surrounding organisms.”
“We really want to make the public aware of these associated risks. In particular, caution should be exercised regarding the harvest and processing of sargassum biomass until the risks are explored more thoroughly,” Mincer said.Vibrio describes several species of bacteria that live in certain coastal waters and can cause human illness called vibriosis, according to the Centers for Disease Control and Prevention. The most common species in the U.S.
