Gizmodo: CDC Warns About Deadly 'Flesh-Eating' Bacteria Found in Warm Coastal Waters https://gizmodo.com/deadly-flesh-eating-bacteria-warm-coast-waters-cdc-1850810578 #necrotizingfasciitis #healthmedicalpharma #bacterialdiseases #disasteraccident #vibriovulnificus #environment #vibrionales #vulnificus #infection #vibrio

Because I swim in the Hudson River, I've gotten lots of links to this NYTimes article about this vibrio bacteria. Two people died in the NY Metropolitan area. What about Florida? Sea water gets a bit warm there. https://www.floridahealth.gov/diseases-and-conditions/vibrio-infections/vibrio-vulnificus/index.html Does anything like this even exist for the Gulf Coast? Do any of those southern states even track this?

Humans have been using the oceans as a dumping ground for decades, so when flesh-eating bacteria attaches itself to microplastics and single-cell organisms mutate into urchin-killing forms, it doesn't surprise me. I honestly don't know how we're going to solve this kind of shit. Maybe "praying" to the aliens isn't such a bad idea. I remember an old bit of graffiti from the 1990s read, "Space Brothers [sic] help us. Save us from ourselves." Indeed! 👽

#FLORIDA ALERT: A 5,000-mile wide blob of murky Sargassum #seaweed that’s been creeping menacingly across the #Atlantic has hit the Florida coast, and now giant clumps are washing up on local #beaches. Not only does the decomposing seaweed smell like rotten eggs, but scientists are warning of a real-life threat from the piles of brown algae — namely high levels of a FLESH-EATING bacteria. #news #usa #nature #globalwarming #bacteria #MedMastodon #vibrio

#Vibrio Colonization Is Highly Dynamic in Early #Microplastic-Associated #Biofilms as Well as on Field-Collected #Microplastics

by Katharina Keys, et al, December 2020

Abstract:

"Microplastics are ubiquitous in aquatic ecosystems and provide a habitat for biofilm-forming bacteria. The genus Vibrio, which includes potential #pathogens, was detected irregularly on microplastics. Since then, the potential of microplastics to enrich (and serve as a vector for) Vibrio has been widely discussed. We investigated Vibrio abundance and operational taxonomic unit (OTU) composition on polyethylene and polystyrene within the first 10 h of colonization during an in situ incubation experiment, along with those found on particles collected from the Baltic Sea. We used 16S rRNA gene amplicon sequencing and co-occurrence networks to elaborate the role of Vibrio within biofilms. Colonization of plastics with Vibrio was detectable after one hour of incubation; however, Vibrio numbers and composition were very dynamic, with a more stable population at the site with highest nutrients and lowest salinity. Likewise, Vibrio abundances on field-collected particles were variable but correlated with proximity to major cities. Vibrio was poorly connected within biofilm networks. Taken together, this indicates that Vibrio is an early colonizer of plastics, but that the process is undirected and independent of the specific surface. Still, higher nutrients could enhance a faster establishment of Vibrio populations. These parameters should be considered when planning studies investigating Vibrio on microplastics."

#Florida researchers find ‘high amounts’ of #FleshEating bacteria in #Sargassum

by Dylan Abad, May 30, 2023

"A new study from Florida Atlantic University is uncovering how the seaweed interacts with #plastic debris and Vibrio bacteria to create the 'perfect pathogen storm' for beachgoers and marine life.

"Samples collected by FAU revealed that Vibrio pathogens had harnessed the unique ability to 'stick' to #microplastics within the seaweed blob. The findings further showed that some #Vibrio bacteria had an ‘omnivorous’ lifestyle that targeted both plant and animal hosts.

"'Another interesting thing we discovered is a set of genes called ‘zot’ genes, which causes leaky gut syndrome,' said assistant professor Tracy Mincer, Ph.D.

"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.

"Simply put, the combination of the bacteria and microplastics could be responsible, in part, for the rapid growth of Sargassum."
