The dogma of bacteriology and other events as spearheads of virology

Abstract

This review analyzes some of the main events during the twentieth century that led to the birth of virology. In the literature of the time, a relationship of causality was established between virus and disease, and within this pathological context, the notions of fixed virus, volatile virus, contagium vivum fluidum and contagium fixum were formed. The transformation of the virus concept as a technoscientific object took place based on the criterion of filterability and on the methodology devised for the bacteriology dogma. Studies on tobacco mosaic virus are highlighted, as well as those on viral diseases of human beings and animals, which led to the discovery of these submicroscopic agents through the appropriation of technologies and the impulse triggered by political and economic factors.
