====== Serial Passage ====== **Serial passage** refers to the process of growing [[bacteria]], [[virus]]es, or other [[microorganism]]s in one environment, traditionally a [[cell culture]], then transferring it to another environment, often repeatedly, in order to select for the survivors. This can be done for the purpose of introducing a microorganism to an animal host as a way to engineer [[zoonosis]]. ===== Link dump to sort ===== https://onlinelibrary.wiley.com/doi/10.1002/bies.202100017
