Szczepionka przeciwko mykoplazmozie kur

Attempts have been made to prepare a vaccine against poultry toxoplasmosis. Mycoplasma gallisepticum antigen mixed with an oil adiuvant (Emulsigen) was used. The vaccine passed innocuity and potency tests carried out under laboratory conditions positively. It has been found that intramuscular administration of 0.3 ml of the vaccine to 3-5 week-old chickens produced the best immunological response. Totally, over 12 000 chickens have been vaccinated in field conditions with good results determined on the basis of epidemiological observations.
