Viruses, bacteria, parasites, fungi: who does what, and how each one spreads
In cycle 1 you learned to recognise Newcastle disease, Gumboro and coccidiosis. But a technician does not settle for a list of diseases: he understands what causes them. A virus, a bacterium, a parasite and a fungus do not live the same way, do not travel the same way and do not die the same way.
