[Comparison of the diagnostic indices in poultry treated against fowl typhoid pullorum]

A study was carried out on the influence of the treatment with furasolidon and altabactin, alone and in combination with spectam and Esb3, in naturally infected and chronically suffering from typhus-puporosis fowls. It was proved that the treatment leads to a clinical but not to a epizootological recovery. It was also proved that the treatment of fowls against typhus-pulorosis, did not have any effect on the sensitivity, the specificity and the detectability of the allergic reaction, whereas the diagnostic value of the serological reaction always diminished. With all the fowls treated, characteristic pathohistological changes were detected, typical of typhus-pulorosis, which make more complete the results of the serological, the allergic and the bacteriological studies, and contributed to the detection of chronically ill fowls.
