[Experience in the complex vaccination of birds against pseudoplague, infectious laryngotracheitis and diphtheria pox].
The immunity was studied as conferred by the simultaneous vaccination against Newcastle disease (strain La Sota), infectious laryngotracheitis (strain "TsNIIP"), and fowl pox (strain FK), applied at different sites. The vaccine against Newcastle disease was diluted at 1 : 10 and was applied nasally through instilling one drop in each orifice. When it was mixed with a vaccine against infectious laryngotracheitis at a ratio of 1 : 1 it was applied via the cloaca or nasally, orally, muscularly or through the ocular sinus. The vaccine against fowl pox was applied at the same time at dilution of 1 : 50 through the wing web. The effectiveness of the immunity conferred was checked through challenge infection, haemagglutination inhibition reactions, and virus-neutralization in chick embryos. It is stated that the resulting stress accompanying every vaccination was not stronger with the combination used than that in other cases. This was also an advantage over the alternative of administering the vaccines alone. The immunity against the three diseases, obtained at the simultaneous application of the vaccines, did not differ from that resulting from administering the vaccines alone. This, XXX indisputably, points to the fact that the method is equally useful from an epizootiologic and an economic standpoint.
