Preparation of vaccine
1. Use only clean, cool, non-chlorinated, preferably distilled water of C. The
volume of water for reconstitution should be sufficient to ensure an even
distribution when sprayed onto the birds. This will vary according to the size of
the birds being vaccinated and the management system, but 250 to 400 ml of
water per 1000 doses is recommended. Follow the instructions of the fine-
spraying device.
2. Open the vial submerged under water.
3. Remove the seal and stopper from the vial.
The reconstituted vaccine must be clear, with no flocculation or sediments.
Administration
1. Vaccinate with a fine-spraying device suitable for nebulization application of
vaccines (particle size: < 100 µm). The vaccine suspension should be spread
evenly over the correct number of birds, at a distance of approximately 40 cm.
2. Do not use any disinfectants, skimmed milk or other agents impairing the
performance of the vaccine in the fine-spraying device.
3. Shut off all fans and close air-inlets while fine-spray vaccinating.
4. Clean the fine-spraying device thoroughly after use according to the
manufacturer’s recommendation.

gallisepticum.
Vaccinated future layers may excrete the vaccine strain up to 15 weeks following
vaccination.

birds, geese, and ducks. Special precautions should be taken to avoid spreading of
the vaccine strain to those species. Seroconversion may occur after vaccination.
The vaccine strain can be differentiated from wild Mycoplasma gallisepticum based
on routine DNA analysis.
