Causes of Quail bronchitis
Mostly young Bobwhite quail are susceptible to this acute to chronic disease. The agent involved in the aetiology of this disease is an Adenovirus, which is an unenveloped, icosahedral double-stranded DNA virus that replicates in the nucleus forming basophilic inclusion bodies.
Mode of transmission
It is spread by airborne route.
Special note
It may cause immunosuppression.
Effects of Quail bronchitis
(There is a 2.7 day incubation period). Signs include coughing, sneezing, huddling, depression, lacrimation, conjunctivitis and neurological signs (tremors and paralysis).
Post mortem lesions
Lesions include mucous in the trachea or bronchi, air sacs and cloudy corneas, and sinusitis. Foci in liver, spleen mottled and swollen, and reddened lungs are consolidated, and atrophy of bursa of Fabricius can be seen.
Diagnosis of Quail bronchitis
Isolation of virus from trachea in embryonated eggs is important. Neutralization of virus with specific sera is also helpful. It Simulates Aspergillosis, and Newcastle Disease.
Treatment & Control of Quail bronchitis
Prevention
Biosecurity and sanitation are helpful to control the disease.
Treatment
Broad-spectrum antibiotics for secondary invaders are also helpful.
