B)Diseases with clearcut syndromes (collections of associated signs and symptoms)
C)Pathogen strain variability
D)Obligate intracellular metabolism of some pathogens
E)All are equally confounding

Diseases with clearcut syndromes (collections of associated signs and symptoms) do not complicate the application of Koch's postulates. In fact, having a clear understanding of the symptoms associated with a disease can aid in the identification and isolation of the pathogen responsible for the disease.
