<br/><br/> Capripox viruses infect only ungulates and most strains of the virus tend to cause clinical disease in only one species ( Carn, 1993 ) . Different strains of the virus appear to have different degree of virulence in different species ( Kitching and Taylor , 1985 ) . Capripox viruses control without vaccination is extremely difficult in endemic areas
