Bajor, Dist. Sikar, Pin – 332001, India ABSTRACT It is caused by a virus belonging to the genus Gyrovirus of family Circoviridae. The virus is a 25nm in size and has a negative ssDNA circular molecule of approximately 2,300 nucleotides with three open reading frames (Nulty et al., 1990). The three reading frames encode for VP1, VP2 and VP3 proteins (Natesan et al., 2006). VP1 is the major capsid protein, VP2 is required for viral assembly and VP3 for disease pathogenesis (Miller et al., 2005). The virus is resistant to pH 3 and temperature 175 F for 30 min and so more difficult to eliminate them from affected farms. CIA is much important due to its frequent outbreaks in commercial poultry industries and is considered as one of the emerging diseases of poultry at global level.
