Abstract

Torque teno virus (TTV), a species of Anellovirus, is a non-enveloped single stranded DNA virus with a wide range of animal hosts. The incidence of TTV is quite ubiquitous throughout the world. A total of 235 serum samples obtained from 137 pigs and 98 cattle at slaughterhouses in Korea during April 2005 to May 2005 were tested by TTV-specific PCR as to monitor prevalence of TTV among swine and cattle. As a result, the prevalent rates of TTVs in pigs and cattle were 43.1% and 4.1%, respectively. It seems that TTV infection is quite prevalent in swine population.

Key Words: cattle, prevalence, swine, TTV
