- Adenovirus infection — An infectious and contagious disease caused by adenoviruses, structurally and functionally affecting the mucous membranes of the respiratory, digestive, or ocular tracts, as well as the associated lymphoid tissue. This condition manifests clinically through a variety of syndromes, including pharyngitis, conjunctivitis (pharyngoconjunctival fever), gastroenteritis, or mesenteric adenitis, being particularly common among children.
- Adenovirus — A genus of medium-sized, non-enveloped viruses with an icosahedral structure and a double-stranded DNA genome, responsible for a wide range of infectious diseases in humans and animals. This structural pathogen frequently infects the linings of the respiratory, digestive, and ocular tracts, causing rhinitis, pharyngitis, gastroenteritis, or epidemic conjunctivitis.
- Aphanobionta — An archaic or neologistic systematic designation used in certain evolutionary biological classifications to group viruses and other submicroscopic infectious entities, characterized by the complete absence of an independent cellular structure and the inability to replicate outside a living host cell. The term highlights their hidden nature, invisible under conventional light microscopy, and their absolute dependence on the biochemical machinery of the parasitized organism.
- Amphotropic — Describing plant ovules: an accepted orthographic variant for 'amfitrop', describing a structure strongly bent in a horseshoe shape; in virology, describing a virus (especially a retrovirus) capable of infecting and structurally replicating within both the cells of its original host species and cells of different species, exhibiting a dual tropism.
- Anavirus — A virus structurally modified through physical or chemical methods that completely loses its replication capacity and virulent pathogenicity, while preserving its original antigenic structure intact. This attenuated biological preparation is used in immunology to stimulate the production of protective antibodies within modern vaccines.
- Anti-coronavirus — Combating, neutralizing, preventing, or halting the multiplication and spread of viruses from the Coronaviridae family (including SARS-CoV-2); an antiviral medication, monoclonal antibody, immunological vaccine, or surface disinfectant specifically formulated to destroy or inhibit the viral structure in the organism or the environment.
- Antiretroviral — Combating, inhibiting, or halting the replication of retroviruses, particularly the human immunodeficiency virus (HIV). As an adjective, it describes medications, therapies (such as HAART), or clinical protocols designed to block different stages of the viral replication cycle (reverse transcriptase, protease, integrase). As a noun, it denotes the therapeutic agent used to lower viral load, protect the immune system, and prevent progression to AIDS.
- Antiviral — Destroying viruses or halting their replication inside host cells; a medication or biological agent (such as acyclovir or oseltamivir) used in the treatment of viral infectious diseases. These compounds act by blocking viral membrane attachment, inhibiting genetic material replication, or preventing the release of new virions.
- Antiviral — Combating viruses, destroying their infectious structure, or halting their intracellular replication; a medication used as a perfect synonym for the term antiviral, but preferred within Romanian clinical and pharmaceutical jargon to classify active substances (such as ganciclovir or ribavirin) prescribed for treating chronic hepatitis, influenza, or herpes.
- Antiviral therapy — A specialized branch of clinical medicine or a complex therapeutic protocol based on the combined and controlled administration of antiviral drugs aimed at eradicating, suppressing, or controlling infections caused by severe pathogenic viruses (such as HIV, hepatitis B and C, or influenza viruses), preventing cellular damage and the progression of chronic disease.
- Autoinoculation — A pathological process whereby an infectious agent (particularly viruses such as HPV, Molluscum contagiosum, or herpes simplex) is mechanically transferred by the patient from an existing primary lesion to another, healthy area of their own body. The phenomenon frequently occurs through scratching, shaving, or direct friction, leading to the local or regional expansion of the cutaneous or mucosal disease.
- Bacteriophage — A virus that infects and destroys exclusively bacterial cells, utilizing their genetic mechanisms to replicate. In a medical and biochemical context, bacteriophages (or phages) represent an extremely specific and ecological alternative to antibiotics, used in phage therapy to combat drug-resistant superbugs.
- Bacteriophagy — A biological phenomenon consisting of the destruction, lysis, or phagocytosis of bacteria by specific viruses (bacteriophages) or by cells endowed with macrophage capacities. In a narrow sense, the process describes the dynamics of the lytic cycle in which entire bacterial populations are rapidly reduced under viral infection, playing a crucial role in the ecological regulation of microbial biomass.
