Opportunistic etiological agents causing lung infections: emerging need to transform lung-targeted delivery
blood test for bacterial infection :: Article Creator Engineered Universal Blood Made Possible By Bacterial Enzymes Credit: Mathias Jensen Bacterial enzymes can cleave sugars that are part of a type A or B blood cell antigen, converting them to type O. Bacterial enzymes may help increase the supply of universal blood. There is an outsize demand for type O blood, specifically because it includes red blood cells that can be transfused into anyone without the risk of the recipient's immune system attacking those cells. This is because types A and B blood cells have characteristic sugar molecules attached to the H antigen, while type O blood cells simply present the H antigen. This feature makes type O blood the most valuable in an emergency when a patient needs a transfusion but there's no time to determine their blood type. This demand means that type O blood is the first to run out during a blood shortage, but a solution may be on th...
