'''When opening the air cell of a suspected dead Canada goose egg, you encounter the situation shown above.'''
 
<FlashCard questions="4">
|q1= What is the aetiological agent that produces the pathology seen in this egg?
|a1= The figure shows a fungal infection growing in the air cell of the membrane.

The most common aetiological agents producing such growth are ''Aspergillus sp.'', typically ''A. fumigatus'' but occasionally ''A. flavus''.
|l1= Aspergillosis#Birds
|q2= In addition to the lesion pictured, what are the other signs of this particular causative agent found in embryos or newly hatched birds?
|a2= Embryos may die before hatching or be weak and dyspnoeic after hatching.

Occasionally, nervous system problems or diarrhoea are found in birds that survive to hatch. Post-mortem findings include bronchial or tracheal plugs, air cell plaques or small yellow nodules in the lungs.
|l2= Aspergillosis#Birds
|q3= What is required for positive diagnosis?
|a3= Cultures of lesions on the air cell membrane, lungs, air sacs or air passages are collected for positive identification.
|l3= Aspergillosis#Birds
|q4= What are recommended treatments and preventive measures for this problem?
|a4= There is currently no recommended treatment for eggs infected with aspergillosis; efforts should be concentrated on prevention.

Aspergillosis can be a serious problem in forced-air incubators. Always clean and fumigate incubators and hatchers between batches of eggs and operate an ‘all in, all out’ policy. Eggs should be examined – weighed; candled; examined for cracks – at regular intervals.

Dead eggs should be removed at once as contamination of viable eggs by dead Aspergillus-infected eggs can occur. Eggs from damp or wet nests should not be incubated. UV sterilization of eggs may be used prior to incubation, as may sanitizing dips or washes.
