Animal pathogens are disease-causing microorganisms—including bacteria, viruses, fungi, and parasites—that primarily infect animals but may share evolutionary origins, transmission vectors, or host-range overlaps with plant-associated pathogens. Understanding animal pathogens is increasingly relevant to plant science because some microbes can infect both plant and animal hosts, and studying cross-kingdom pathogen biology helps researchers identify conserved infection mechanisms and immune evasion strategies. This comparative approach informs the development of broader disease management strategies and sheds light on how pathogens evolve and jump between host kingdoms.
