Survival of this bacteria off birds: Days to Weeks !

Common worldwide: Particularly in fall and winter in tropical and temperate climates.

Carrier: Most birds that have had or been exposed to Coryza become either an active or passive carrier. They will eventually keep this bacteria active and pass it on to birds not exposed, some may never become active with coryza but will be carriers in the future.

Symptoms: First sign is sneezing & foamy-swollen eyes followed by clogging of the nostrils & sinuses, (sometimes a clear looking liquid is present). As symptons progress over a few days the drainage from nostrils & sinuses becomes a sticky, putrid-smelling exudate. This becomes cheesy and accumulates in the sinuses and eyes, causing the face        and eyes to appear extremely swollen. In some cases wattles may also appear to be somewhat swollen. There is normally a decrease in water consumption. Once this happens comb & wattles may become bluish although not always and the droppings will be off color. Fertility disappears and laying stops.

Treatment: Immediately remove chicken from area located near other birds. Cage & treat

separately - if possible put cage in separate barn or garage.

As soon as symptoms appear and you are unsure of the treatment, contact your poultry supplier or

your vet immediately.

Symptoms may disappear after 3 days but it is only hidden and will reappear quickly if not given

the medication the appropriate number of days.

Symptoms may reappear in this bird or others that have been exposed indefinitely. Treatment will

be on- going for the rest of its life and will keep this bacteria active or passive in your coop

forever.

Prevention: Culling is preferable since survivors (including all birds in the flock) may be carriers. This is not always possible so disinfecting your coop may be preferable. Consider that this disease will always be with us in the United States until all birds with this disease are eradicated.
