For each of the following: Cyanobacteria, Coronavirus, Chytrids, Ciliates, and Chronic wasting disease. Explain with details how does the pathogen invades our tissues and body after transmission. You need to include any receptors, steps etc. in its life cycle and/or the type of replication or reproduction it exhibits and how and where it exits the cells, tissues, or body. This section can also include how it spreads through the body if that is relevant.
