With respect to their life cycles, how are fungal pathogens different than bacterial pathogens?
What will be an ideal response?
Answer: Some bacterial pathogens have life cycles that depend on human infection to propagate and/or disperse the infectious agents; however, fungal pathogens do not depend on humans to thrive. Pathogenic fungi essentially have an unlimited reservoir of soil, so they are impossible to eradicate. Pathogenic bacteria often have reservoirs that limit their abundance.
