Virology
scientific study of biological viruses
Virology is the scientific study of biological viruses. It is a subfield of microbiology that focuses on their detection, structure, classification and evolution, their methods of infection and exploitation of host cells for reproduction, their interaction with host organism physiology and immunity, the diseases they cause, the techniques to isolate and culture them, and their use in research and therapy.
The identification of the causative agent of tobacco mosaic disease (TMV) as a novel pathogen by Martinus Beijerinck (1898) is now acknowledged as being the official beginning of the field of virology as a discipline distinct from bacteriology. He realized the source was neither a bacterial nor a fungal infection, but something completely different. Beijerinck used the word "virus" to describe the mysterious agent in his 'contagium vivum fluidum' ('contagious living fluid'). Rosalind Franklin proposed the full structure of the tobacco mosaic virus in 1955.
As an applied science, virology forms a significant portion of medical microbiology and medicine. The application of virology in veterinary medicine is called veterinary virology, and the study of plant viruses forms part of plant pathology. Viral pathogenesis is the branch of virology studying how viruses infect and cause diseases to their hosts.
Virology began when there were no methods for propagating or visualizing viruses or specific laboratory tests for viral infections.
The public source identifies “Virology” as scientific study of biological viruses. This brief keeps that definition visible, then builds a research path around Virology, scientific and study.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Virology”, the useful work is to connect “scientific study of biological viruses” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q7215. The Library of Congress control number is sh85143799. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1898 and 1955.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
- Current terminology
- Classification context
- Finding cited technical literature
Primary datasets, specimen catalogues, standards bodies and the most recent peer-reviewed literature.
Three-step research path
- Establish the record: confirm the title “Virology”, its source revision and the description used here.
- Expand the search: follow Virology primary sources, Virology archive and Virology research across catalogues and specialist indexes.
- Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
