• viruses
  • Because antiviral agents taken prophylactically may prevent illness but not subclinical infection, some persons who take these drugs may still develop immune responses that will protect them when they are exposed to antigenically related viruses in later years. (cdc.gov)
  • Biological warfare (BW)-also known as germ warfare-is the use of biological toxins or infectious agents such as bacteria, viruses, and fungi with the intent to kill or incapacitate humans, animals or plants as an act of war. (wikipedia.org)
  • Biological weapons (often termed "bio-weapons", "biological threat agents", or "bio-agents") are living organisms or replicating entities (viruses, which are not universally considered "alive") that reproduce or replicate within their host victims. (wikipedia.org)
  • These agents are bacteria, viruses, fungi, or toxins, and may be in a naturally occurring or a human-modified form, in much the same way in biological warfare. (wikipedia.org)
  • According to the U.S. Centers for Disease Control and Prevention, bioterrorism is the deliberate release of viruses, bacteria, toxins or other harmful agents to cause illness or death in people, animals, or plants. (wikipedia.org)
  • treatment
  • A combination treatment consisting of three antiviral agents - the HIV-protease inhibitor Invirase, Hivid and AZT - may be a better option for HIV-infected persons than dual therapy with AZT plus either of the other drugs, according to a study in today's New England Journal of Medicine. (thefreedictionary.com)
  • The American Uveitis Society has established the following guidelines for ARN diagnosis: Retinal necrosis with one or more focus points borders in the peripheral retina In the absence of antiviral treatment, the condition progresses rapidly Spreading to the surroundings Buildup of blood vessels Inflammation of the vitreous. (wikipedia.org)
  • Currently treatment of ARN consists of antiviral therapy administered orally. (wikipedia.org)
  • biological agents
  • The use of biological agents in armed conflict is a war crime. (wikipedia.org)
  • Therefore, biological agents may be useful as strategic deterrents in addition to their utility as offensive weapons on the battlefield. (wikipedia.org)
  • Bioterrorism is terrorism involving the intentional release or dissemination of biological agents. (wikipedia.org)
  • Biological agents can be spread through the air, water, or in food. (wikipedia.org)
  • Terrorists tend to use biological agents because they are extremely difficult to detect and do not cause illness for several hours to several days. (wikipedia.org)
  • cells
  • Recent work has been done by virologists to learn more about the interference in infection of host cells and how DI genomes could potentially work as antiviral agents. (wikipedia.org)
  • typically
  • Unlike bioweapons, these midspectrum agents do not reproduce in their host and are typically characterized by shorter incubation periods. (wikipedia.org)
  • These agents are typically found in nature, but could be mutated or altered to increase their ability to cause disease, make them resistant to current medicines, or to increase their ability to be spread into the environment. (wikipedia.org)
  • less
  • In the absence of specific contraindications, amantadine and rimantadine are preferred for use in most patients because these two agents cost less than the other two. (umsystem.edu)
