Concurrent avian pox and Newcastle disease infection in a Houbara bustard (Chlamydotis undulata)

Abstract

A case of acute respiratory disease was observed on a 3-month-old Houbara bustard (Chlamydotis undulata) at the National Wildlife Research Center (NWRC) breeding unit. Newcastle disease (ND) and avian pox viruses were isolated from the lungs, spleen and trachea of the affected bird. A heavy secondary bacterial infection was also noticed. The clinical and pathological findings observed in this case are described. It is the first description of the isolation of ND virus from a Houbara bustard. The epidemiology of the disease in the breeding flock is discussed. © 1995, Taylor & Francis Group, LLC. All rights reserved.
