title: 100th anniversary of virology.
abstract: A short review of the beginnings of virology is presented, when Beijerinck formulated his concept of a new category of disease agents in plants. With the discovery of similar etiologies in diseases of animals (foot-and-mouth disease) and humans (yellow fever), the universality of this concept emerged and the discipline of virology was born.
