Post Weaning Multisystemic Wasting Syndrome - Threat for Piggery Farming in India

Porcine circovirus have been associated with multiple disease syndromes in pigs, including post weaning multi-systemic wasting syndrome, porcine dermatitis and nephropathy syndrome and reproductive disorders which lead to economic loss in swine industry. Virus has been detected in all body secretions. Affected pigs are unthrifty, dyspnoea with a marked expiratory effort, pallor, rough hair coat, enlarged inguinal lymph nodes and diarrhoea. Detection of PCV2 antigen or nucleic acid by polymerase chain reaction is considered the gold standard for the diagnosis. Genetic mutation in porcine circovirus makes difficult in control however, vaccination against PCV2 is only available preventive strategy and protects the swine farmers from the economic losses.
