Abstract

Infectious bronchitis in broiler chickens in Iraq. I. Isolation and identification of the isolant (AM 88).

Abstract

Infectious bronchitis was recorded in 2- to 5-week-old broiler chickens in Iraq. The disease was characterized by respiratory symptoms and high mortality. The main post-mortem findings indicated a mucoid plug in the tracheal bifuractions. The isolate, AM 88, was obtained from the trachea and lungs of infected birds. This isolate produced curling, dwarfing and about 10% deaths in infected chick embryos after 3 passages. The physico-chemical characteristics of the isolate revealed that it did not agglutinate avian or ovine erythrocytes.
