Outside of a host or living cell, a virus is an inactive particle but once a host cell is detected and entered, it becomes active, taking over the cell’s metabolic machinery for the synthesis of new viral particles called virions. Virions are viral particles that consist of RNA or DNA with a protein cost and act as the infectious form of the virus, in turn going on to impact other host cells.
Influenza Virus & Bacteriophage
There are a variety of methods for detecting viruses including PCR (Polymerase chain reaction) which is, in recent times, conspicuous with SARS-CoV-2 (Coronavirus). This technique makes copies of the virus genomes using virus-specific probes, this then tests for the presence of the target virus. Sequencing is another nucleic acid-based method of detecting the presence of a virus as well as providing researchers with the full sequence of the genome. In addition to these methods, there are microscopy-based methods that can detect the presence of viruses too, for example, immunofluorescence. This method utilizes IFA (immunofluorescent assay) to identify the presence of viruses by reaction with viral antigens in infected cells [4,5].
