Microorganisms constitute more than 90% of the biomass in the sea. It is estimated that viruses kill approximately 20% of this biomass each day and that there are 10 to 15 times as many viruses in the oceans as there are bacteria and archaea. [205]
Viruses infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea. [138] [139] More than 6,000 virus species have been described in detail. [140] Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. [141] [142]
This is a list of all virus species, including satellites and viroids. Excluded are other ranks, and other non-cellular life such as prions. Also excluded are common names and obsolete names for viruses. The taxonomy is taken from ICTV taxonomy 2022 release [1] For a list of virus families and subfamilies, see List of virus families and ...
Coxsackie B virus: Coxsackie B virus infection Enterovirus infection is diagnosed mainly via serological tests such as ELISA and from cell culture.

[21] [22] According to the World Health Organization, approximately 10 million new TB infections occur every year, and 1.5 million people die from it each year – making it the world's top infectious killer (before COVID-19 pandemic). [21] However, there is a lack of sources which describe major TB epidemics with definite time spans and death ...
Many latent and asymptomatic viruses are present in the human body all the time. Viruses infect all life forms; therefore the bacterial, plant, and animal cells and material in the gut also carry viruses. [6] When viruses cause harm by infecting the cells in the body, a symptomatic disease may develop.
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 ...
