Poultry Avian Pox Study Guide
Overview and Clinical Importance
Avian pox (fowl pox, fowlpox) is a slow-spreading viral disease of poultry caused by viruses of the genus Avipoxvirus within the family Poxviridae. This disease has worldwide distribution and represents a significant economic concern in the poultry industry due to decreased egg production, poor growth, and potential mortality in severe cases.
Avian pox is characterized by two distinct clinical forms: the cutaneous (dry) form affecting unfeathered skin areas including the comb, wattles, and eyelids, and the diphtheritic (wet) form causing fibrinonecrotic lesions in the upper respiratory and digestive tracts. Understanding this disease is essential for NAVLE success as it frequently appears in board examinations.
