This fits with most medical school curricula since the causative agents span the full spectrum of medical microbiology (viruses, bacteria, protozoa, ectoparasites, and so on). This classical approach often proves difficult in clinical practice, where many different types of agents must be considered in the differential diagnosis of an individual patient.
