Coryza is a kind of infection of the upper respiratory tract and very often seen in racing pigeons. The coryza affection can have several causes and is usually a combination of different disorders which work together:
- a viral herpes infection
- a bacterial Chlamydophila infection
- a mycoplasma infection
- a bacterial E. coli infection
In case of an infection we can see a quick deterioration of the condition and performance of the sick pigeons. A bad hygiene, less ventilation and an overpopulation on the loft are the main reasons for these respiratory problems. In case of chronic respiratory problems the treatment can be difficult; only a long treatment will give a good result.
