High frequency of pathogenic bacteria poses risks to preterm or immunocompromised infants
Samples of human breast milk purchased through Internet milk-sharing sites were frequently contaminated with pathogenic bacteria and exhibited high overall bacterial growth, a recent study found. Consumption of milk obtained from these largely unregulated websites can introduce risks for infants, especially those born preterm or with immunecompromised status, the lead researcher says.
Researchers develop system that concentrates foodborne pathogens by using hollow thread-like fibers to filter out the cells
One of the most stubborn bottlenecks in rapid detection and identification of foodborne pathogens has long been the very first step: Concentration of enough cells to accurately identify the pathogen. Current standard methods of cell concentration take about 24 hours, but a new method developed by researchers at Purdue University could cut that time to as little as one hour.
