[Comparative studies of agglutinin formation in poultry experimentally infected by various routes with Salm. gallinarum-pullorum].

It has been established that the immunologic response in birds is directly associated with the way of infection. Parenteral treatment has proved to be the most effective route in establishing the highest degree of titers as early as the 6th day following injection -- 1:754. Using the intravenous route of infection the titers are found on the eighth day -- 1:580; at the intramuscular infection as well as the accomplished via subcutaneous injection the titers are observed on the tenth day --1:364. At oral infection the peak in the agglutination titer curve is noted on the twentieth day -- 1:383 (comparatively later); it has been found that the titers in this case remain at one and the same level for a much longer period of time.
