Abstract. Koch’s postulates were formulated in the late nineteenth century as guidelines for establishing that microbes cause specific diseases. Because the rules were developed for living agents—particularly bacteria—their applicability to inanimate pathogens such as viruses and infectious proteins has been problematic.
