A new gyrovirus in human feces

A novel gyrovirus genome found in the feces of an adult with diarrhea is described. The genome shows the three expected main ORFs encoding a structural protein (VP1), nonstructural protein (VP2), and Apoptin protein (VP3), which shared identities of 41, 42, and 38 % with those of the most closely related gyrovirus proteins, respectively. Given the high divergence in its genome, this gyrovirus may be considered the prototype for a new viral species (GyV9) in the Gyrovirus genus. Because the closest relatives of this gyrovirus infect chicken, a possible dietary origin for the presence of this virus in human feces is discussed.
