Summary:After a brief reference to the ordinary use of the "Komarov" mesogenic vaccinal strain of Newcastle disease virus for the secondary vaccination of domestic fowls, the authors deal with laboratory experiments conducted to ascertain that this strain can be used for the same purpose by the drinking water method. Three groups of chickens 45 days old previously vaccinated with LaSota strain in the drinking water at 20 days old, were revaccinated with the normal dose by the "Komarov" strain, as follows: a) intramuscularly, b) by the drinking water and c) per os. A fourth group was left as negative control. To investigate the effect of the revaccination by the two different routes of administration, the hemagglutination-inhibition test was used. The results of these tests are finally compared and discussed.
