Researchers at Duke Medicine and Duke-NUS Graduate Medical School Singapore found the Yersinia pestis bacteria that cause bubonic plague hitchhike on immune cells in the lymph nodes and eventually ride into the lungs and the blood stream, where the infection is easily transmitted to others. 'This work demonstrates that it may be possible to target the trafficking of host immune cells and not the pathogens themselves to effectively treat infection and reduce mortality,' St. John said. With antibiotics, most people get better. Its an example of a disease that can spread between animals and people (a zoonotic disease).
