Bacterial Studies Assessing Damage to Eco-System
Dr. Wilma Subra, Toxicologist and Louisiana native explains her studies of the Gulf at a Truth Out Forum Held February 5, 2011 in New Orleans to a crowded church house of ill people, concerned journalists and people that want the truth.
“While visible damages are evident in the wildlife populations and marine estuaries, the most significant effect may be on the most basic level of the ecosystems: the bacterial and plankton populations,” wrote researchers in a study Feb. 28 in Nature Precedings. “Abrupt and severe changes in the microbial metabolism can produce long-term effects on the entire ecosystem.”
Led by biologist William Widger of the University of Houston, the researchers sequenced DNA from near-shore water and beach-soil samples gathered before and after oil arrived in Gulfport, Mississippi, and Grand Isle, Louisiana, following the blowout last spring.
By cross-referencing the DNA to microbe gene databases, they identified populations of bacteria and how they changed. Vibrio cholera, the bug that causes cholera, spiked upward after the spill. So did Rickettsiales, an order of bugs whose diseases include typhus and spotted fever. Here is a great Explanation by Brandon Keim called Deepwater Horizon’s Impacts Found in Bacteria.
