New Assay Rapidly Detects Pathogens in Marine Mammals

A three-year project by NCCOS scientists has culminated in a reliable tool for rapid detection of pathogenic Brucella bacteria in clinical samples from marine mammals. Rapid detection of these pathogens in marine mammals has been difficult ever since Brucella infections were first recognized in marine mammals in the 1990s. Brucellosis, a Brucella-based reproductive disease, is […]

Environmental Conditions Can Influence Development of Dermo Disease in Oysters

A recent NCCOS-sponsored study by the Smithsonian Institution showed that long-term exposure to daily fluctuations of hypoxia (low dissolved oxygen) increased Dermo disease (Perkinsus marinus) infection in previously uninfected eastern oysters. Surprisingly, daily-cycling pH (a measure of acidity) did not affect Dermo disease infection levels in conjunction with daily-cycling hypoxia or with continuous normal oxygen […]

NCCOS Identifies Cause of Large Fish Kills in North Carolina Estuaries

In recent years, North Carolina estuaries have experienced large fish kills often associated with rains and moderate temperatures. Most of the dead fish have exhibited large, open skin ulcers. Scientists at NCCOS analyzed the ulcerated fish collected by the North Carolina Department of Environment and Natural Resources (NCDENR) and the Neuse Riverkeeper Foundation using molecular assays […]

NCCOS Study on Antibiotic Resistance in Bacteria Safeguards Environmental and Human Health

Antibiotics may enter marine ecosystems from wastewater systems, agricultural run-off (particularly from concentrated animal farming operations), as well as direct release from aquaculture waters.  NCCOS intern and University of South Carolina Masters of Public Health candidate, Keri Lydon presented findings from an NCCOS study focused on determining antibiotic resistance in the environment and overall risks to marine […]

Toxic Turtles: Long-lasting Chemicals Could Be Harming Sea Turtles | Environmental Health News

From the moment they are born, sea turtles fight to survive. Buried alive, they dig themselves out and evade hungry crabs and birds as they crawl to the ocean, where they begin a long and treacherous migration. One out of 1,000 will survive into adulthood. And those that do will bear a toxic burden. Scientists […]

Recreational Water Pathogen Detection Workshops Build Skills for State Labs

The North Carolina Biotechnology Center funded NOAA and academic researchers to develop a training facility for public health officials and resource managers in advanced molecular methods to detect pathogens and harmful algae species more quickly and effectively. The first workshop, held March 11 – 15, 2013,  covered quantitative polymerase chain reaction techniques to detect Enterococcus, the […]

New Research Points to Better Method to Weigh Risk of Antibiotic Resistance in Bacteria | National Ocean Service

A recent study demonstrates a new approach that may allow scientists to better approximate the risks for bacteria to develop resistance to different families of antibiotics. In the study, conducted by NOAA’s National Centers for Coastal Ocean Science and the Arnold School of Public Health at the University of South Carolina, resistance genes from E. […]

S.C. Dolphin Drama: Humans Try to Help Distressed Animal | The Post and Courier | Charleston SC

The dolphin was coming straight up out of the water, making pitiful moans and then going back down, slowly swimming around the Bushy Park Boat Landing. Cathy Murphy spotted it Friday. It looked like something might be wrapped around its tail, dragging it down. “ We’ve watched dolphins for years, and we knew something was wrong,” she […]
