Diseases of poultry, Edition 8: Case history and sample collection: This variation might be due to the fact that their work was on disease outbreak and may also be due to the laboratory techniques employed; unlike the present study, they used antibody detection technique where there are numerous false positives due to cross protections [ 48 ]. Chickens are primarily affected, although the disease has occasionally been reported in pheasants and guinea fowls Charlton et al.

Buchanan RE, Gibbons, eds. No outbreak occurred during the study although there were numerous chicken showing sign of coryza.

The products of most cells, heterophil, and macrophages may be responsible for the severe vascular changes and cell damage leading to coryza. In susceptible chickens the symptoms first appear about hours after exposure to infection.

A cross sectional study on paraagallinarum coryza was conducted in Jimma, Ethiopia, from November to April with the objectives of determining the prevalence of infectious coryza, and associated paraglalinarum. The highest incidence was observed January to April. The disease is seen more frequently on intensive chicken farms, especially on large-scale egg production complexes and breeding farms Charlton et al.
