However, they are also involved in a wide range of other biological activities, including immune patrolling, cell migration, and binding to cells by certain viruses, such as adenovirus, echovirus, hantavirus, and foot and mouth disease viruses.

On the basis of their pathogenesis in humans and animals, the enteroviruses were originally classified into four groups, polioviruses, Coxsackie A viruses ( CA ), Coxsackie B viruses ( CB ), and echoviruses, but it was quickly realized that there were significant overlaps in the biological properties of viruses in the different groups.

:: In the case of myalgic encephalomyelitis ( ME ), " almost clueless " may be an appropriate way to describe the current understanding of the metabolic etiology of this disease; but the primal etiology of ME perhaps warrants a " possibly due to " chronic infection with Coxsackie B viruses, and / or echoviruses, and / or herpes family viruses, as well as various toxic contributory causes.
