Word Finder - viruses

definition

A submicroscopic, non-cellular structure consisting of a core of DNA or RNA surrounded by a protein coat, that requires a living host cell to replicate, and often causes disease in the host organism.

As a consequence of co-evolution with their hosts, viruses have acquired host genes and genetic mutations that confer dominance over normal cell function.

Whether due to viruses or bacteria, the infection is spread from person to person by airborne droplets, hand contact or kissing.

The pathogens include bacteria which cause dysentery, viruses responsible for polio and hepatitis, and many others.

The viruses colonize the gut mucosa and provoke antibody formation both in the blood stream and in the gut epithelium.
