A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. [1] Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea.
Bacteriophages are viruses that infect bacteria and archaea. [76] They are important in marine ecology: as the infected bacteria burst, carbon compounds are released back into the environment, which stimulates fresh organic growth. Bacteriophages are useful in scientific research because they are harmless to humans and can be studied easily.

Viruses and other microorganisms are so tiny that they get swept up into the atmosphere in small particles from soil-dust and sea spray, returning to the Earth via rain, snow, and sandstorms ...
Coxsackie B virus infection Enterovirus infection is diagnosed mainly via serological tests such as ELISA and from cell culture. There is no well-accepted treatment for the Coxsackie B group of viruses. Under research [10] PRNP: Creutzfeldt–Jakob disease (CJD) No Crimean-Congo hemorrhagic fever virus Crimean-Congo hemorrhagic fever (CCHF) No
Gamma phage, an example of virus particles (visualised by electron microscopy) 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 ...
Diverse viruses colonize the human skin and differ by skin site. [27] This skin virome includes human viruses (i.e. human papillomavirus) and bacteriophages (bacterial viruses) that infect commensal skin bacteria such as Staphylococci. [28] Virus communities differ by moisture levels and degree of protection from the external environment. [27]
On the whole, flu A viruses tend to cause a more intense illness, Dr. Russo says. “Both flu A and flu B can be lethal, but flu A tends to cause more severe disease,” he says.
