Abstract
Mycoplasma gallisepticum (MG) infections are commonly known as chronic respiratory disease
(CRD) of chickens. The infection with this bacterium is characterized by respiratory rales, coughing,
nasal discharge and conjunctivitis (Ley, 2003). Economic losses from condemnation, reduced egg
production and increased medication costs make CRD one of the costliest disease problems
confronting poultry production. Complicating infections like colibacillosis and some live vaccines
are known to result in more sever MG diseases (Mohammad et al., 1987 and Gross, 1990). A case
of misdiagnosis leading to use of live infectious bronchitis virus (IBV) vaccine which exaggerated
CRD in layer chickens is reported.
