Researchers report in the journal Geohealth that local rivers and streams were the source of the Salmonella enterica contamination along coastal North Carolina after Hurricane Florence in 2018 – not the previously suspected high number of pig farms in the region. 

These findings have critical implications for controlling the spread of disease caused by antibiotic-resistant pathogens after flooding events, particularly in the coastal regions of developing countries that are being highly impacted by the increase in tropical storms. 

Aquatic birds, especially ducks, can carry influenza viruses but they don’t often become severely ill, leading scientists to wonder how their immune systems act as a reservoir for a highly infectious and pathogenic virus, but the birds remain relatively unharmed. Additionally, could the immune system be engineered to thwart transmission to other animals and humans, ultimately preventing future pandemics?

Salmonella are food-borne pathogens that infect millions of people a year. To do so, these bacteria depend on a complex network of genes and gene products that allow them to sense environmental conditions. In a new paper, researchers have investigated the role of small RNAs that help Salmonella express their virulence genes.

Compost—organic material that is added to soil to help plants grow—is widely used by gardeners because it improves soil health and reduces the amount of organic waste in landfills. Although several studies have looked at commercial composts, very few have investigated backyard compost samples. In a new study, researchers have measured the number of pathogens in both types of compost.
