Infectious Coryza - 'Avibacterium Paragallinarum'
by the Cuckoo Stud
Due to alarming reports of an increase in this disease I am including this article here to hopefully give a better understanding
This is written resulting from research and consultation with professionals in the Avian field.
Coryza (Avibacterium Paragallinarum) is not transmitted via eggs.
The disease is spread quickly and easily by the infected bird simply using communal feed and water containers, also by sneezing and/or shaking the head which releases the disease into the air.
Coryza is a highly contagious respiratory disease, characterized by foamy conjunctivitis, sinusitis, nasal discharges, depression and lethargy.
The disease is believed to live only a few days away from the host bird. The best method of control is to depopulate, clean everything (everything, meaning everything on the property, not just the chook stuff), wait a few weeks after the cleaning then repopulate with birds that are known not to be infected. You can use eggs from infected birds to repopulate as the incubation period is longer than the life span of the disease outside the host.
The use of these eggs is also assuming you have thoroughly cleaned everything to help eradicate the disease before the eggs hatch
There is no such thing as a survivor of this disease; once they get it they always have it in their systems.
These infected birds are carriers and will spread the disease, mainly when stressed.
These birds will also have recurring bouts of the disease throughout their lives, they are highly contagious at these times.
There is no natural immunity to the disease.
Adult birds that have the disease do not pass immunity on to their offspring via the egg as neither the disease or any unfounded perceived immunity is transmitted via the egg.
Meaning the human factor using good bio-security with incubated eggs and chicks raised away from infected birds have little chance of contracting the disease.
There is no immunity to this disease. Infected birds will have recurring bouts of the disease their entire lives, predominantly during periods of stress. At these times they are more contagious than at non-stressed times.
Coryza is easily spread via contaminated feeders, waterers, your clothes etc. Also by sneezing birds and obviously sick birds.
Strict bio-security is the only way to help stop the spread of this disease if you insist on keeping infected birds.
If you decide not to cull known to be infected birds, whether they display symptoms or not, down the track standard antibiotics will not work due to resistance by the disease itself. You will then have to acquire more powerful types of antibiotics perpetuating the cycle as you can only treat the disease you cannot cure it.
In some cases Mycoplasma Gallisepticum can also be present with the Coryza.
Infections from Coryza are known to cause losses in flocks.
Coryza does affect laying ability. Affected flocks in lay can suffer drops in egg production from 5% to total loss (100%).
Sick birds can be treated with antibiotics, which should bring egg production levels back up
.
Antibiotics will not cure Coryza, carrier birds will spread it to others birds, mainly under stressful conditions.
Infectious Coryza vaccination will not stop the birds being infected.
However, this can lessen the signs of the disease and reduce its spread. All vaccinated birds are to be considered carriers.
Vaccination programmes for layers and/or breeders usually consists of a 2 dose regime.
The first vaccination, both sexes, is from 6 to 8 weeks of age. A second vaccination for pullets at point of lay is recommended.
The vaccination only protects from the symptoms it does not protect from the disease.
All vaccinated birds are to be considered carriers.
