These genes help the body trigger and and direct its immune response to an infection. 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 includes providing guidance on which specimens should be collected and the best diagnostic tests to use. However, death rates varied from place to place. Although the lack of clear records makes it hard to be precise, historians generally estimate the Black Death killed between 30% and 60% of Europes population between 1347 and 1351.

New research has said that clinical microbiology is critical to understanding COVID-19, with laboratories studying the coronavirus globally. 'Meanwhile, the immune cells send signals to bring in even more recruits, causing the lymph nodes to grow massively and providing a safe haven for microbial multiplication.'. While microbes are responsible for most of the methane produced on earth, contributing to global warming, this methane can also be beneficial as it can be used as a biofuel an alternative source of energy helping in the fight against climate change.
