[Crisis and blood coagulation in chickens with experimental spirochetosis].

Studied was the process of blood clotting in normal bursectomized and entire young birds, as well as in the conditions of experimentally induced spirochaetal infection. Use was made of 10 bursectomized and 10 nonbursectomized month-old birds. It was found that blood clotting with the uninfected bursectomized birds was more strongly manifested as compared to the entire ones. At the 120th hour following infection of the bursectomized birds the clotting of blood was comparatively more weakly expressed than it was in the nonbursectomized ones.
